Episode 33: Dr. Natalie Batalha talks about exoplanets and the possibility of life in our Milky Way and beyond
Dr. Natalie Batalha’s STEM-Talk interview was so contagious that Dawn Kernagis said it made her dream of returning to school to get a second graduate degree in astronomy.
“Hearing Natalie talk about her research had all of us in the STEM-Talk studio buzzing,” said Dawn, the podcast’s co-host.
Natalie is an astrophysicist and the project scientist for NASA’s Kepler Mission, a space observatory launched by NASA to discover Earth-sized planets orbiting other stars. She sat down with Dawn and veteran astronaut and IHMC senior research scientist Tom Jones for episode 33 of STEM-Talk.
As one of the original co-investigators of the Kepler Mission, Natalie has been a leader in using the telescope to discover exoplanets, which are planets that orbit stars other than our own sun. Natalie has been involved in the Kepler Mission since the proposal stage and has helped identify more than 150,000 stars that are monitored by the telescope.
She holds a bachelor’s degree in physics from The University of California Berkeley, and a doctoral degree in astrophysics from UC Santa Cruz. She taught physics and astronomy for 10 years at San Jose State University before joining the Space Sciences Division of the NASA Ames Research Center, which is located in California’s Silicon Valley.
In 2011, Natalie received a NASA Public Service Medal for her vision in communicating Kepler’s science to the public, and also for her outstanding leadership in coordinating the Kepler science team. That same year Natalie also headed up the analysis that led to the discovery of Kepler 10b, the first confirmed rocky planet outside our solar system.
She joined the leadership team of a new NASA initiative in 2015, which is dedicated to the search for evidence of life beyond our solar system. Called the Nexus for Exoplanet System Science, the program brings together teams from multiple disciplines to understand the diversity of worlds, and which of those exoplanets are most likely to harbor life.
As if Dawn and the STEM-Talk gang weren’t excited enough after talking to Natalie about the search for life beyond our solar system, NASA announced about a month after our interview with Natalie that its Spitzer Space Telescope had revealed the first known system of seven Earth-sized planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
According to a NASA press release in February, the discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water – key to life as we know it – under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.
0:30: Dawn welcomes Ken Ford, IHMC founder and director as well as the chairman of the Double Secret Selection Committee that chooses guests who appear on STEM-Talk. Dawn and Ken then talk about Natalie’s background as an astrophysicist.
4:35: Dawn welcomes her co-host for this episode of STEM-Talk, Tom Jones, and they begin the interview by asking Natalie how she became interested in astronomy.

25:30: Natalie talks about lava worlds, which have oceans larger than the Pacific Ocean, but they’re made of lava, which is why scientists call them lava worlds.
27:30: Dawn asks Natalie about the discovery of Kepler 10b, which was the identification of the first rocky planet outside of our own solar system.
32:30: Natalie describes how the host star that Kepler 10b orbits is almost exactly like Earth’s sun, except that it’s about 8 billion to 11 billion years old as opposed to our sun which is four and a half billion years old.
36:30: Dawn reads a quote that describes the discovery of Kepler 10lb as one of the most profound scientific discoveries in human history and asks Natalie to talk about that.

Episode 32: Dr. Claire Fraser explains how our gut microbes improve our health, prevent disease and even play a role in our mental health
Women who are pregnant often talk how careful they are about what they eat and drink. They’re careful, points out Dr. Claire Fraser, because they’re feeding their baby.
“Well, we should all think about diet in the same way that pregnant women do,” says Fraser. “Everything we put into our mouths, we’re either feeding or not feeding our gut microbes … And it’s important we keep our gut microbes happy.”
Fraser is a pioneer and global leader in genomic medicine, a branch of molecular biology that focuses on the genome. In episode 32 of STEM-Talk, Fraser sits down with host Dawn Kernagis and IHMC founder Ken Ford to explain why we should all pay more attention to our guts, which is the home of more than 100 trillion bacteria.
An endowed professor at the University of Maryland School of Medicine, Fraser is a founder and director of Maryland’s Institute for Genome Sciences. From 1998 to 2007, she was the director of the Institute for Genomic Research in Rockville, Maryland, and led teams that sequenced the genomes of several microbial organisms, including important human and animal pathogens.
In 1995, she became the first person to map the complete genetic code of a free-living organism, Haemophilus Influenza, the bacterium that causes lower respiratory tract infections and meningitis in infants and young children. This discovery forever changed microbiology and launched a new field of study, microbial genomics.
During this time, she and her team also sequenced the bacteria behind syphilis and Lyme disease, and eventually the first plant genome and the first human-pathogenic parasite. She even helped identify the source of a deadly 2001 anthrax attack in one of the biggest investigations conducted by U.S. law enforcement.
Research into the benefits of gut bacteria has exploded around the world in the past decade. In this STEM-Talk episode, Fraser explains the role these microbes play in improving health, preventing disease, and keeping us mentally sharp. She even shares how her diet has changed since she started studying the gut microbiome.
Fraser also talks about working with the FBI during the 2001 antrhax attacks and her early work in microbiology that led to the first mapping of a free-living organism’s complete genetic code.
Her recent lecture at IHMC, titled “The Human Gut Microbiome in Health and Disease,” can be viewed at ihmc.us/lectures.
If you’re interested in learning more about the gut microbiome, Fraser in her lecture recommended “The Good Gut: Taking Control of Your Weight, Your Mood, and Your Long-term Health” by Stanford University scientists Justin and Erica Sonnenburg.
1:36: Dawn reads the five-star iTunes review titled “Intellectually Stimulating.”
2:28: Dawn and Ken provide a summary of Claire’s background and research, pointing out that she has authored more than 320 scientific publications, edited three books, and has served on committees of the National Science Foundation, Department of Energy, and National Institutes of Health.
4:13: Dawn welcomes Claire to STEM-Talk.
4:27: Claire talks about growing up in a suburb of Boston and taking her first biology course as a freshman in high school, which set her on a path toward a career in science.
5:37: Dawn asks Claire what led her to study microbiology.
6:53: Ken points out that there are more microbes on a person’s hand than there are people in the world. He asks Claire to give listeners a short intro into “Microbiome 101.”
9:34: Claire talks about the role of Lactobacillus rhamnosus GG (LGG), a strain of bacteria that is part of many popular probiotic products and has a reputation as a helpful microbe.
12:00: Ken asks Claire to expand upon the potential of probiotics and their usage in human beings.
14:56: Dawn points out that Claire is internationally known for her role in genome sequencing and asks what led Claire to establish the Institute of Genomics at Maryland.
18:02: Claire talks about her involvement in the first genome sequencing and where the technology stands today.
22:39: Dawn follows up with a question about how the evolution of sequencing technology has changed the way we monitor the spread of pathogens.
29:26: Claire talks about some of the new sequencing technology on the horizon.
32:02: Ken asks Claire to explain the kind of data-analysis challenges that this new technology is creating.
34:29: Claire describes her experience working on the anthrax attacks in 2001, which at the time was one of the biggest investigations conducted by U.S. law enforcement.
41:39: Dawn asks Claire about the effects of antibiotics on the gut.
47:00: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
47:25: Fraser talks about the early science of fecal transplants.
50:04: Ken asks Claire about the role of the microbiome in obesity and chronic diseases like diabetes.
52:38: Dawn asks what kinds of solutions there are against antibiotic-resistant strains.

Episode 31: Dr. Michael Turner, who coined the phrase ‘dark energy,’ talks about the deepest issues in cosmology
Dr. Michael Turner makes a “big bang” in the world of theoretical cosmology. Translation: He’s an expert on the universe—what it’s made of, what’s in its future, and how it came to be.
Turner is the Rauner Distinguished Service Professor and Director of the Kavli Institute for Cosmological Physics at the University of Chicago. From 2003 until 2006, was Assistant Director for Mathematical and Physical Sciences for the National Science Foundation. He is the recipient of numerous awards and prizes, and he is a Fellow of the American Association for the Advancement of Science (AAAS).
Michael Turner and Vera Rubben, who recently passed away.
Turner is most well-known for having coined the phrase “dark energy” in 1998, which he calls “very, very mysterious stuff.” Thought to comprise 70 percent of the universe, dark energy is responsible for both the expansion of the universe and the increasing speed at which that expansion is occurring.
Another five percent of the universe is atoms, and the remaining twenty-five percent is “dark matter”—what Turner calls “the cosmic infrastructure of the universe.” The universe, he adds, has largely “been a battle between the two dark titans: dark energy and dark matter.”
“He [Turner] is able to explain the deepest issues in cosmology with a rare clarity and elegance,” says IHMC Director Ken Ford. “His research focuses on the earliest moments of creation.”
With Chicago cosmologist Rocky Kolb, Turner co-wrote the well-known book “The Early Universe.”
More information on Turner can be found here: https://kicp.uchicago.edu/people/profile/michael_turner.html and here: https://en.wikipedia.org/wiki/Michael_Turner_(cosmologist).
Turner’s 2011 IHMC lecture, “The Dark Side of the Universe,” can be viewed here: . Turner was also a guest on STEM-Talk for an earlier episode for his interview on the discovery of gravitational waves.
Turner is interviewed by regular STEM-Talk host Dawn Kernagis and guest host Tom Jones, a veteran NASA astronaut and senior research scientist at IHMC.
00:37: Ken calls Dr. Michael Turner “exactly the right guy to talk to about dark energy and dark matter. After all, he coined the phrase dark energy. He is able to explain deepest issues in cosmology with a rare clarity and elegance.”
1:04: Ken pays tribute to Vera Rubin, who passed away on Christmas Day. She confirmed the existence of dark matter and transformed modern physics and astronomy.
2:24: Ken asks for feedback on STEM-Talk and reads 5-star iTunes review from BobRXUF: “With all of the garbage we are bombarded with, listening to STEM-Talk reminds me that there is higher intelligence, the hope for mankind.”
3:35: Dawn and Ken introduce Michael and talk about his background.
4:17: Dawn and Tom welcome Michael to STEM-Talk.
4:39: Tom asks Michael to give listeners the big picture about the structure of our universe and explain how we stumbled upon the phenomenon called dark matter and dark energy?
5:14: Michael explains that a half of one percent of the universe is in the form of stars. The other 99.5 percent is dark.
6:29: Michael talks about how dark matter matter provides the cosmic infrastructure of the universe.
7:45: “Our universe,” says Michael, “has really been a battle between the two dark titans: dark energy and dark matter.”
9:49: Michael explains that’s it’s the stars that give off energy and it’s the atoms we’re made of. “We’re the tip of the iceberg. We’re the special stuff.”
10:52: “Michael talks about producing dark matter particles at the Large Hadron Collider (LHC) in Geneva, Switzerland, the world’s most powerful particle accelerator.
11:25: Tom asks Michael what was the original evidence for dark matter and dark energy and who were the people who made that discovery?
13:20: Michael describes how Vera Rubin, a scientist working at the Department of Terrestrial Magnetism at the Carnegie Institution of Washington, was able to confirm dark matter at work in our own galaxy.
15:06: Tom asks if it’s dark matter that holds things together and makes the clock, the universe, tick?
17:37: Michael explains how Fritz Zwicky and Vera Rubin went about building empirical evidence for dark matter.
19:40: Michael talks about research into “neutralinos,” particles that scientists speculate are left over from the Big Bang. “We’re in the midst of this detective story.”
21:24: Tom asks if the facilities and equipment exist to solve the mystery of the neutralinos and the dark-matter particle?
24:31: Commercial break.
24:55: Dawn wonders if our understanding of dark matter and dark energy continues to advance, what future applications might arise from this knowledge?
25:21: Michael explains that if scientists are able to verify the existence of the neutralino, “it would be the first evidence of the super string theory, which unifies all the forces—a very, very bold theory that says there may be additional dimensions in space-time.”
27:20: In continuing to answer Dawn’s question, Michael says, “If history is any guide, any time we understand nature a little better, there will be spin-offs and practical applications that change and improve the way we live.”
27:43: Tom asks Michael to talk about dark energy and the continuous expansion of the universe.
28:54: Michael shares how two teams discovered in 1998 that rather than slowing down, the expansion of the universe is speeding up, suggesting it’s back to the drawing board on the ultimate fate of the universe.
30:18: Michael talks about what he describes as the most profound mystery in all of science: that gravity can be repulsive rather than attractive.
32:48: Michael refers to a theory that could prove to be even grander than Einstein’s. This new theory says that “as the universe thins out, after expanding for 15 billion years, it starts to speed up.
35:27: Tom asks about Congressional funding for the National Science Foundation research and Turner explains that almost every country on earth is grappling with funding allocations for science.
42:22: Michael talks about the James Webb Space Telescope (JWST), which he describes as big and bold and the kind of project that only the U.S. can do.
43:17: When Dawn asks Michael what led him to become a cosmologist, he talks about how great high school teachers led him into science.
43:51: Michael encourages young people to pursue careers in science. “Just about every challenge that our country and our planet have involves science…trying to understand the secrets of nature and solve the mysteries of mankind are really, really exciting. The career opportunities are good.”
44:41: Michael describes the rewarding nature of his career. “I get to think about the mysteries of the universe. I get to think about how the universe began and how it will end. That’s a pretty good job to have.”
46:3: Tom talks about getting his first telescope when he was 12 years old and how that was a gateway into science.
47:19: Dawn recaps the “mind-boggling statistics” Turner shared in the podcast, staring with 99.5 percent of our universe is dark.
47:38: Ken talks about the great turn of phrases Michael used during the podcast, such as when Michael referred to the evolution of the universe as a “battle between two dark titans.”

Episode 30: Art De Vany Talks About Hollywood Economics, the Paleo Way, and the Role of Fitness and Diet in Aging
Dr. Art De Vany is an American economist known for his work on the Hollywood film industry. He is perhaps best known, however, as the grandfather of the paleo diet, a high-protein, high-fiber way of eating similar to the way our hunter-gather ancestors ate during the Stone Age.
Born in 1937, he has had a varied career that began right out of high school when he signed a baseball contract with the Hollywood Stars, a minor-league affiliate of the Pittsburg Pirates. Even though he could “run like a deer” and “hit the ball out of sight,” his poor eyesight ended his baseball career and led him the UCLA where earned a doctorate in economics. He spent most of his academic career studying Hollywood and the film industry. His research has ranged from “Hollywood Economics: How Extreme Uncertainty Shapes the Film Industry” to “Quality Revaluations and the Breakdown of Statistical Herding in the Dynamics of Box Office Revenues.”
De Vany turns 80 in August and has spent the past 40 years living the paleo way. He outlined his diet and fitness philosophy in “The New Evolution Diet: What Our Paleolithic Ancestors Can Teach Us About Weight Loss, Fitness and Aging.” https://www.amazon.com/New-Evolution-Diet-Paleolithic-Ancestors-ebook/dp/B004EBT6SS/ref=sr_1_1?s=books&ie=UTF8&qid=1487717091&sr=1-1&keywords=New+evolution
He is working on a new book that’s tentatively titled “Renewing Cycles: Healing the Wounds of Aging Through Improved Cellular Defense and Systemic Signaling.” De Vany gave a lecture at IHMC in Pensacola last December where he talked about the New Evolution Diet” as well as his upcoming book on aging.
In Episode 30 of STEM-Talk, host Dawn Kernagis and IHMC Founder Ken Ford have a wide-ranging conversation with De Vany that covers his statistical study of home-run hitting to the dynamics of box-office revenues to the role that exercise and diet play in aging.
0:15: Dawn welcomes Ken, who talks briefly about Art’s background.
1:32: Dawn announces the winning iTunes review.
2:05: Dawn and Ken give an overview of Art’s career and research.
3:12: – Dawn welcomes Art to the show.

7:40: Ken and Art compare the lean physiques of great sluggers active in the ‘50s, ‘60s and ‘70s such as Ted Williams, Hank Aaron and Carl Yastrzemski with today’s much larger home run hitters.
10:37: Art recalls how debates with one of his professors at UCLA about central planning versus decentralized control systems led him into economics.
13:10: Dawn asks Art to talk about his research into the economics of Hollywood.
16:17: Art explains the impact of movies like “The Titanic,” which can generate 10 percent of all the box-office revenues during a year that will see 600 to 700 movies that are released.
17:06: Dawn asks Art to share his fondest scientific and professional memories.
18:11: In 1979, Art’s newborn son is diagnosed with type 1 diabetes and leads to Art’s interest and research into metabolism.
20:20: Dawn asks Art to describe the most profound power laws he has discovered in his pursuit to counter the aging process.
22:26: Ken shares his thoughts about “The New Evolution Diet,” which he describes as beautifully built on Art’s personal interest in evolution and his professional interest in complex stochastic systems.
25:26: Art explains how the book grew out of his realization that insulin controls the pathways that drive growth and obesity as well as shutting down the protective pathways.
26:45: Art describes genes as Bayesian forecasters arising from non-genetic influences on genetic expression.
28:17: Ken inquires about Art’s time at the Institute for Mathematical Behavioral Sciences, which Art describes as a dream place for him.
30:05: Dawn asks Art to expand upon his comment that there’s no such thing as healthy aging.
33:22: Art responds to Dawn’s question about Blue Zones and points out that the healthiest long-term aging individuals have low insulin, high strength, and they have not exhausted their subcutaneous body fat.
36:10: Ken asks Art about the role that exercise and diet play in epigenetics and molecular-level changes.
41:10: Art addresses how muscle development aids the immune system and how strength is probably the best predictor of a person’s future longevity.

Episode 29: Leonard Wong Discusses a Culture of Dishonesty in the Army
Dr. Leonard Wong, a research professor at the Strategic Studies Institute (SSI) of the U.S. Army War College, led an important study titled: “Lying to Ourselves: Dishonesty in the Army Profession.” The study, which was published in 2015 generated much discussion as well as some consternation and reflection.
www.strategicstudiesinstitute.army.mil/pdffiles/PUB1250.pdf
In this episode, Host Dawn Kernagis and IHMC’s Director Ken Ford talk with Wong about his study and its implications. Wong also lectured about his study at IHMC in Pensacola last September:
http://www.ihmc.us/lectures/20160907/.
Wong’s research focuses on the human and organizational dimensions of the military and includes topics such as leadership development in the military profession. He is a retired Army Officer and taught leadership at West Point. He is also an analyst for the Chief of Staff in the Army. Wong’s research has led him Iraq, Afghanistan, Bosnia, Kosovo and Vietnam. He has testified before Congress and has been featured widely in the media, including the New Yorker, the Washington Post, the New York Times, PBS, NPR, 60 Minutes and CNN.
Wong is a professional engineer and holds a Bachelor’s from the U.S. Military Academy. He also has a Master’s and a Ph.D. in business administration from Texas Tech University.
1:43: Ken reads five-star iTunes review from “CC Rider,” which is entitled “Intelligent Podcast: What a Relief:” “What a pleasure to hear intelligent, articulate people discussing worthwhile topics.”
2:17: Dawn describes Wong’s bio.
3:18: Dawn welcomes Wong and Ken.
3:42: Wong describes his role at the U.S. Army War College, as well as the College’s structure. When Army leaders arrive at the War College, they’ve generally been in the Army for twenty years. They’re at the point of thinking strategically about leadership and their roles.
5:27: Wong’s research into this topic started over a decade ago, with the question of how to build more time into the schedule of junior offices to facilitate innovation. Wong and his colleagues discovered an overwhelming amount of requirements, which were stifling Innovation. In the back of his mind, Wong concluded: ‘If we require more than they can possibly do, what are we reporting?’
6:36: Wong, in conversation with his colleague Steve Gerras, once asked him what he was doing on his computer. He was supposedly doing mandatory training, but not really. He said, ‘I know, I’m just saying I did it.’ Wong realized then ‘how casually we approach lying, but we don’t call it lying.’
7:15: The theory of Wong’s subsequent study came from a book entitled “Blind Spots: Why We Fail to Do What’s Right and What to Do About It,” by Max Bazerman and Ann Tenbrunsel (http://amzn.to/2gBJtib), along with what David Messick called ethical fading. The methodology was to use focus groups from various ranks throughout the Army, including staff officers at the Pentagon.
8:12: Dawn mentions that Wong’s study had a precedent: In 1970, the U.S. Army War College published a study showing that lying in the Army was pervasive. Digitization, the audit culture, and downsizing have made it worse today.
8:43: Wong says, “The Army is like a compulsive hoarder. It collects requirements, and it never gives any up. We always add more. We keep adding to the pile. Technology has made a huge influence on this.” Now, with email and Internet, we can ask people to provide digital signatures, and do various online trainings.
9:42: Wong characterizes another part of the problem: “The Army has had a giant emphasis on being a profession. It’s a good thing, but it’s made us believe that we are better than we are. We forget that we are humans. We forget that we are talking about people who can fall to the same temptations, go the same route, as an ordinary human.”
10:35: Ken asks about Wong’s description of people in the Army being so overwhelmed that they have to prioritize.
10:50: Wong says, “One of the ways to ethically fade is you take away moral aspects…. So you are void of all the baggage that an ethical dilemma brings.” Euphemisms are a common way around this, and prioritize is one way of saying you lied. “Prioritize means taking a risk: We didn’t do it, but are going to still report that we did it. Prioritize is a convenient way to convince ourselves that we haven’t lied.”
12:00: “What this study isn’t saying is we have an institution full of liars, or a cohort of people with low ethics. We’ve created an institution with a bureaucracy…with a system that is putting an onerous burden on people to do everything and report they’ve done it. Inadvertently it creates a culture in which we have to tell a system what it wants to hear or it won’t get done.”
12:39: Wong recalls the old days and how easy it was to take a leave form (31) for travel. Today there is a complicated trips form, in which you have to specify where you are going, when you are stopping, any medications you’re taking, who is traveling with you, vehicle inspections.
13:51: “We’ve surrounded ourselves with an audit culture where we have to tell a system that something has happened when it really hasn’t.”
14:00: Ken comments these are typically for the benefit of “CYA.”
14:13: Wong cites the good intentions of the people behind these requirements.
14:40: Yet he questions whether this is the best system for the desired outcomes. “It’s well-meaning, yet the system we create encourages people to lie to it.”
15:00: Study’s conclusion was that process and paperwork are replacing leadership.
15:38: “We don’t want to replace leadership with a process because a process will always tell us what we want to hear…A leader might not. We can’t always trust leaders because leaders are human. That’s where we may prefer a process, which gives us a green light. But it may not be telling us the truth.”
16:30: Ken comments that the growth of procedures and lack of discretion left to leaders “almost presumes poor leadership, judgment, and I think is a step in the wrong direction.”
17:10: Wong says, “We grow leaders. We shouldn’t be ashamed to use leaders, but at the same time we can’t expect leaders to be perfect or their people to be perfect.”
17:43: Wong describes an Army storyboard: In the old days, after an event, someone had to brief an intelligence officer on what they saw/happened. Now the storyboard “allows us to create PowerPoint slides, derived from a template, that has pictures, a narrative and a map.” These have become burdensome to create.
18:30: “You stop focusing on what happened and start focusing on making the storyboard look correctly. It encouraged people to copy and paste; or ignore the storyboard. They would either omit it, or they’d duplicate it, and fabricate them.”
20:46: “There are many things that allowed them to think that they did tell the truth, and technology is one of them. The further you move away from the why…from a statement that you know is not truthful, it allows our mind to rest at ease, and technology allows us to do that.”
21:20: One example of this is annual ratings forms to council the rated officers, which is supposed to happen every quarter. “You have to show you counseled them every quarter. The clerk will fill in dates. They’ll agonize over picking the right dates so it doesn’t fall on the weekend. Tens of thousands are turned in every year.”
23:00: Ken observes that, “In many agencies and companies, and most particularly DoD, PowerPoint has become the defacto communication tool. PowerPoint can obscure the paucity of thought underlying a particular slide. In NASA we used to have a saying, ‘This guy is one slide deep.’”
23:53: Wong notes that PowerPoint is a double edged sword — perfect for briefings when used correctly, but it’s very dangerous when used incorrectly.
25:10: Ken comments that “Jeff Bezos famously banned power point on Amazon as a low information communication medium that often supports the illusion that the presenter actually has a coherent position or argument.”
25:35: Wong says, “PowerPoint when used incorrectly is a lazy man’s tool. But when used correctly, it’s a good stimulus for discussion.”
26:40: Ken talks about the APPP: anti-power point political party in Switzerland. Their stance: “Decreasing professional use of PowerPoint and other presentation software, which the party claims, causes national economic damage, and lowers the quality of the presentation in 95 percent of the cases.”
28:44: Some examples of ridiculous training compliance modules: Every Marine, including those that have never smoked, are required to take a smoking cessation class. This year Wong had to take training on fetal alcohol syndrome. “That’s when you get in the mind, ‘This is a dumb requirement,’ and that helps me breeze through it.”
30:00: “The danger of all these trivial examples is that added up, it creates a culture. Some reports are really important…so many reports people view as dumb. Because of this culture we’ve created, we give them permission to lie about what’s dumb.”
31:08: Dawn asks what is worse: the lying, or the pervasive perception that it’s not lying; and that we’re above lying.
31:20: Wong says, “The lying is a problem but can be corrected. If we don’t admit that we do this, then we’re headed for hypocrisy, for hubris, and that’s more of a problem.”
31:42: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
32:24: Wong describes ethical fading as “removing the glare of the bright colors of moral decisions. You make it so it’s not black and white, right or wrong. You make it so it’s gray. One way to do that is to numb us: We start psychologically disconnecting from the ethical part of it.” One example: Every year to use computer systems in Army, they have to sign a statement that says, ‘I have read, understood and agreed with the procedures …” Preceding that is a 1900-word document. “Every single person initials that, and I haven’t met anyone who has actually read it.”
33:26: Wong mentions that in the U.K. they did an experiment where they offered free Wi-Fi to people and one of the agreements was ‘I promise to give my first born.’ “They had to stop that because every single person signed up for it. We don’t think we’re lying to a person; we think we are lying to a system. That distance allows us to convince ourselves that we don’t lie.
34:20: Wong discusses the potentially more serious implications of the lies.
35:05: “You add up all these Iraqi units that were graded green, and we had a very good Iraqi Army on paper. Then we saw what happened when ISIS came in, and suddenly all these green units didn’t perform the way all our power point slides said they did.”
35:28: Wong reflects on his own experience with compliance measures in the Army: “I remember feeling pressured, but not to the degree that they do today.”
36:32: Ken calls Wong’s study “brave.” He asks about the reaction in the Army, and whether it was rank-dependent.
36:55: Wong says it was “eye-opening.” After some initial anger, “I started getting emails, calls, and notes from people throughout the Army: You’ve just exposed what everyone knows about. Senior leaders had a hard time acknowledging it.”
38:02: “The more senior you go in an organization, the less you have to comply with these trivial requirements.”
38:50: After the anger died down, the leadership came to realize people were not under attack, but rather a culture that had been created. “To see policies change because of a 34-page document…I’m glad to be part of that.”
39:09: Ken comments that the military has a track record of leading the way in cultural changes. The problem is much broader than the military; it reflects the culture of which it’s part.
40:18: Wong says the Army could do three things to improve its situation: First, acknowledge the problem…and that it happens at all levels. Secondly, exercise restraint. “Every level of Army likes to create requirements for those below them, but we need to allow those at the bottom to exercise their own judgment.” Third: We have to lead truthfully.
44:30: Ken notes the tendency to make up words so you aren’t committing a bad act; but rather referring to the word. Prioritize is an example. In the Navy, we used to call it, “Gun Decking or Pencil Whipping.”
45:10: Ken says it is often seen as a key role of a leader to provide “high cover” for subordinates. When you unpack that, it often implies that the leader took the hit; that’s who checked the boxes.
46:10: Ken says Wong’s work is not seen as a criticism of the Army or people; rather of the audit culture… “Little by little, it diminishes the integrity of the force.”
46:46: Dawn directs listeners to Wong’s IHMC lecture: http://www.ihmc.us/lectures/20160907/
46:50: Dawn and Ken sign off.

Episode 28: Mike Gernhardt Discusses the Overlapping Challenges of Working Undersea and in Space
Mike Gernhardt’s career epitomizes the scientific overlap between the depths of the ocean and space. Prior to his career as a NASA astronaut, Gernhardt was a professional diver and engineer on subsea oil field construction and repair projects around the world.
As a child, Gernhardt vacationed in Florida, where he developed a love of the ocean. Like many children, Gernhardt dreamed of becoming an astronaut. However, unlike most kids, he stuck with his dream and began taking steps to pursue it in high school when, in his own words, he “had already put together that working in space and in the sea were similar.”
Gernhardt received his undergraduate degree in Physics from Vanderbilt University, followed by his Master’s and Ph.D.—both in Bioengineering—from the University of Pennsylvania. At the University of Pennsylvania, he worked with his life-long mentor C.J. Lambertson, who is considered to be one of the godfathers of diving medicine.
Under Lambertson, Gernhardt received unparalleled field work experience, testing real-time the decompression tables that he’d developed and still constitute the commercial diving standard.
In 1992, Gernhardt was selected to be an astronaut at NASA, where he completed four space flights and space walks. He also started a company called Oceaneering Space Systems, where he transferred his subsea robotics experience to NASA. Gernhardt stated, “There’s really a lot of synergy between working underwater and working in space, and the design of the task for human and robot compatibility.”
Gernhardt has received numerous awards and honors, including the highly coveted NASA Distinguished Service Medal. To view his bios: https://en.wikipedia.org/wiki/Michael_L._Gernhardt ; http://www.jsc.nasa.gov/Bios/htmlbios/gernhard.html
In this episode, STEM-Talk Host Dawn Kernagis, an esteemed diver and undersea expert herself, and co-host Tom Jones, a veteran NASA astronaut, engage in a thought-provoking conversation.
1:35: Ken reads a 5-star iTunes review from Paula Olivet: “I wish this podcast aired everyday.” This show takes science as a personal, academic and professional venture, which it entirely is. It’s not all pipettes and mice. It’s ambition, and unquenchable thirst for answers. Even when I think the episode subject matter is not for me, I still find myself completely enthralled.”
2:32: Dawn recounts Gernhardt’s educational and professional background: He hold a Bachelor’s degree in Physics from Vanderbilt University and a Master’s degree and Ph.D. in Bioengineering from the University of Pennsylvania. He has been a professional deep sea diver and engineer on projects around world. He was a manager and Vice President of Special Projects for Oceaneering International, and established Oceaneering Space Systems to transfer subsea technology and operational experience to the international space program.
3:05: Ken adds: “His impact on the agency and how we do human space flight is really extensive.”
4:02: Dawn welcomes Mike and Tom to the episode.
4:31: Gernhardt explains his initial interest in diving: “As a four or five-year old I was always going fishing with my dad in Florida. At nine or ten, I was doing scuba diving on a family vacation. I got certified at age 12 and became a dive instructor at 18.” For the first couple of summers after college, he worked as a scuba instructor and boat captain at St. Thomas in the Virgin Islands. Then he got into commercial diving, where he noted the limitations in decompression tables.
5:38: These limitations inspired him to study the physiology and biophysics of diving. In college, he studied physics and math, and was a pre-med major. When he graduated, he wasn’t ready to commit to graduate or medical school, so he worked as a commercial diver.
6:40: Describing his commercial diving experience, he says: “Unlike the more sheltered college environment, here it was like: What can you do in the water at the end of the hose? That really inspired me.”
7:02: The Medical Director of Ocean Systems was C.J. Lambertson, who took him under his wing. Gernhardt decided to go to graduate school at the University of Pennsylvania in order to study with Lambertson. “That turned into a 30-year relationship.”
7:43: “We would generate the new decompression tables, and then I would go out and use them…. We tested them real-time.”
8:05: Lambertson said his ultimate goal was to make the field a laboratory. “In this period of three years, we generated tables that became the Oceaneering standard.” Roughly ten million dives have been done on those tables.
9:09: Dawn calls Lambertson one of the godfathers of diving medicine and asks what it was like to work with him.
9:20: Gernhardt answers: “He was an amazing guy. I started reading his books as an undergraduate. When I then met him for the first time, he looked professorial, older, he had a beard…When you shook his hand, he could squeeze your hand off.” Lambertson was also influential during World War II. “He wrote undersea warfare tactics/strategy that influenced everything, on top of the physiological work he did.”
10:24: Gernhardt adds: “He was a personal friend and father figure. When I was there he would just make the time to sit and talk. He was also a great mentor.” Lambertson read “every word” of Gernhardt’s dissertation. “He was hard on me.”
11:10: Gernhardt explains that Lambertson had been an advisor to NASA for decades and sat on all the review committees. “He was reviewing my work. People at headquarters said that was a conflict of interest. I told them, ‘No one’s going to be harder on me than Dr. Lambertson.’ We kind of fought off the bureaucrats on that and produced stuff that has really enabled the assembly and maintenance of space station.”
13:04: Gernhardt started Oceaneering Space Systems in 1987, where he transferred his sub-sea robotics experience to NASA. He invented the Cryopak, which used liquid oxygen for breathing and cooling to handle issues in micro-gravity. They called it the magnetic intake dewar.
15:02: Of the company, Gernhardt says, “We won a large contract to build a sub-critical liquid oxygen storage system, and we beat out major aerospace contractors. That was exciting for our young company at the time. That transitioned us into the space world.”
17:11: Gernhardt says, “There’s really a lot of synergy between working underwater and working in space, and the design of the task for human and robot compatibility.”
17:34: Gernhardt recalls the aerospace contractors who would go to the shop and think that we were selling atmospheric diving suits that weighed about a ton. “I was selling the concepts, the operational knowledge, the design knowledge, and some of these folks thought they were going to buy a suit from us.”
18:15: His company initially included just him and a secretary. “I hired every commercial diver that I knew, that had gone back and gotten an engineering degree. He combined that with going up to the best universities and interviewing top talent. “We put together this magical combination of seasoned commercial divers and smart as heck MIT and JPL [Jet Propulsion Laboratory at NASA] grads and really did an amazing amount of work.”
18:55: Tom asks him how he gave that all up to become a “worker-bee astronaut.”
19:35: Gernhardt explains that becoming an astronaut had been a lifelong goal of his. “In my early teens, I had already put together that working in space and in sea were similar.” Athletic as well, he had “set the distant goal to be an astronaut.”
20:20: Of his first year on the job (as astronaut), he recalls: “There’s a pile of manuals that go up from the floor past your desk, and you’ve got to learn all this, and then you’ve gotta learn to fly a T-38 jet…and then next thing you know you’re flying in space.”
20:45: Gernhardt says he was different from most astronauts in that his area of academic expertise was directly related to EVA (extravehicular activity.) That allowed him to design tools.
21:25: Gernhardt had invented the body-restraint tether (BRT) for undersea diving that became useful in space, as well.
23:20: Tom describes his experience using the BRT: “It was a dream. It enabled you to scramble anyplace on the space station and then grab onto a handrail with your third arm, which you provided, and that left your hands free. And you could turn your body left, right, in and out, and then you could carry it around just by bending it over your shoulder, and it was out of the way of your other tools. It was a very handy device on the space station.”
24:25: Dawn asks about the similarities between diving and EVA.
24:40: Gernhardt replies: “What’s similar is you’re working in a three-dimensional hostile environment: no air in sea or in space.” Furthermore, the way you think about planning the operation is similar, in terms of A, B and C. But the mechanics are very different: “Underwater we’re not in pressurized suits, so you have more mobility and dexterity. You use your hands to feel, but you also have poor visibility…you tend to use all of your body senses. In EVA you’re in a pressurized suit with a similar inflation pressure as a football or basketball; so, every time you move, you’re fighting that inflation pressure.”
26:18: In space, Gernhardt explains, even though you are “weightless,” you actually are not massless. “You and the suit weigh over 500 pounds in space. If you go fast, you could tumble out of control. My motto was: ‘You cannot go too slow’. Never let your hands get ahead of your brain.”
27:24: Another difference between the ocean depths and space: “In space, you have unlimited visibility. You can see literally millions of miles.”
27:40: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
28:00: Tom asks about Gernhardt’s first EVA because a few weeks before launch, Gernhardt sustained an injury that might have prevented him from participating.
28:30: Gernhardt tells the story: the mission was delayed a week, so he went on a date in Galveston. It was pouring rain and, after dropping his date off at the Grand Theater, he slipped and dislocated his shoulder while running through the parking lot in the rain.
30:10: “I had a great attitude,” Gernhardt says about his recovery and prospect of missing the mission. “If I can do it, great,” he though. “If not, it’s not about me—it’s about the mission.”
32:00: Gernhardt shares an anecdote about how the doctors okayed him for the mission after he proved that he could get in and out of the space suit. “I was in about as much pain as a human can stand. It was a huge mental focus, but it all worked out.”
37:00: Gernhardt talks about the oxygen prebreathe protocol he developed with his team. Fifty subjects experienced no bends, and very few bubbles.
38:42: Tom says: You can see Mike doing the prebreathe protocol on an Imax movie called “Space Station 3D.” https://www.youtube.com/watch?v=O9X84b9t3Do
39:00: Dawn says she was a research assistant on prebreathe protocol at Duke University with Dr. Vann. She assisted with monitoring of subjects and measuring how much they were bubbling at altitude.
40:42: Gernhardt talks about the in-suit light exercise protocol that saves complexity over other exercise protocols. “We use that routinely on space station, and we’ve never had any bends—we’ve had close to 200 EVAs without any decompression sickness.”
41:28: He is working on developing the details of a Phobos Mission in Mars Orbit planned for the 2030s.
42:20: On those missions, he adds, “We would do excursions in a pressurized excursion vehicle,” another of Gernhardt’s inventions. This is a small cabin with great windows; two people live in it for two weeks at a time. The pressure of that cabin is 8.2 pounds per square inch, with 34 percent oxygen.” It puts us at a much better posture for not having to denitrogenate to avoid decompression sickness.”
43:10: Air-lock operations are not fun, Gernhardt says. Tom compares the compressed feeling to “two hippos in the front seat of a Volkswagen.”
43:45: Gernhardt also invented the work efficiency index: the work time you get outside divided by the overhead it took you to get outside. “On the station we spent about two and a half hours inside for every hour outside, and to me that was crazy.”
44:12: “The whole concept is that we have this cabin that is optimized for viewing and low-overhead EVAs. And we can combine that with different mobility elements.”
45:50: Tom characterizes Phobos as a “low-gravity body; the size of a big city.” He asks Gernhardt: “What advantages do we gain from being around Phobos (or Deimos)?”
46:08: Gernhardt answers that Phobos is “very interesting scientifically. It will tell us about the natural history and evolution of Mars… We can pick up pieces of Mars on the Moon of Mars.”
46:55: “It is so much easier to go to the Moon of Mars than Mars’ surface. Mars it the worst place on solar system to try to land because there’s just enough atmosphere to get you hot, but not enough to slow you down.”
47:19: “By going to Phobos, we develop the infrastructure needed to go to Mars.”
48:29: “Phobos is a stepping stone. Ninety-nine percent of everything we would use to go to Phobos takes us towards Mars’ surface.”
48:50: Gernhardt adds that “Mars is only 9,000 Kilometers from Phobos, so every exploration activity or public outreach event that we do will have Mars looming large over the horizon and keep our focus on where we’re going.”
49:10: “My hope is that we sign up to that [going to Mars sometime in the 2030s] and have a plan that we can close a budget around, and really have a focused exploration effort….”
49:50: Gernhardt’s advice to aspiring astronauts: “Get as much education as you can; do things that you like because, if you like them, you’re going to have a good life; you’re going to be good at them…” Do things, he adds, “that are directed towards being an astronaut, but don’t do things that you don’t like in order to be selected as an astronaut.”
50:23: “Learn to be a team player. It’s not about individual super stars.”
50:47: Dawn thanks Mike.
51:48: Dawn marvels at the overlap in the undersea world and space and Gernhardt’s own seamless transition from undersea to space.
52:02: Ken says: “It’s a smooth transition, and Mike depicted it beautifully. He’s a great guy, and a valued collaborator; in fact, he’s truly a man for all seasons.”
52:20: Dawn and Ken sign off.

Episode 27: Robb Wolf Discusses the Paleo Diet, Ketosis, Exercise, Nicotine … and Much More!
For fitness and Paleo Diet aficionados—and perhaps regular STEM-talk listeners—Robb Wolf is the type of esteemed guest who needs no introduction. Many people already know him by his best-selling book, “The Paleo Solution: The Original Human Diet,” (http://amzn.to/2gB6N4c) or his top-ranked podcast by that same name. (http://robbwolf.com/podcast/)
But what some people may not know is that Wolf also started the world’s first cross-fit affiliate gym; that he’s raising his young daughters on a paleo diet—which may account for their mouths having a similar phenotypical expression as hunters and gatherers; and that nicotine—yes, nicotine—can actually be good for you (just not delivered by cigarette) in some contexts.
STEM-Talk Host Dawn Kernagis and IHMC Founder Ken Ford talk to Wolf about these and other fascinating insights in this episode.
Wolf hailed from a relatively unhealthy family, which pushed him towards discovering good health on his own terms. A keen interest and aptitude in science (he was a biochemistry major at California State University-Chico) set Wolf on the path of evolutionary medicine.
He began thinking seriously about pre-agricultural diets in response to his mother’s poor reaction to her consumption of grains, legumes, and dairy. Since that time, Wolf has become an expert, researcher, and self-experimenter of the Paleo Diet. His expertise has led him to become a review editor for Journal of Nutrition and Metabolism; co-founder of The Performance Menu, a nutrition and athletic training journal; and co-owner of NorCal, one of Men’s Health magazine’s top thirty gyms in America. He is also a consultant for the Naval Special Warfare Resiliency Program.
Wolf recently gave a lecture entitled “Darwinian Medicine: Maybe There IS Something to This Evolution Thing” at IHMC: https://www.youtube.com/watch?v=qga4A3vnXmg
2:10: Dawn reads iTunes review entitled “No Bro Science Here” from someone nicknamed “Leafy Sweets:” “Science-based interviews with experts, post-docs and department/lab heads on relevant topics. No Bro Science here! Interesting discussions relevant to one’s well-being and interests.”
3:46: Dawn welcomes Robb and Ken.
4:10: “I was raised by two well-meaning, but quite ill parents. Both of them smoked, neither of them exercised, both of them developed Type-2 Diabetes pretty early in their lives, and I’m not really sure why…but somewhere along the line I suspected that if I ate better and exercised, that I could maybe have a better outcome.”
5:00: “They really kind of acquiesced all their health to the medical establishment, and I went just as opposite that vector as you can possibly imagine.”
5:30: “I had a pretty good interest in science in general… I got into an organic chemistry class (in high school) and loved it like I had never loved anything before, and actually discovered that I had an aptitude for spinning molecules in my head and thinking about bonding and stuff like that.”
6:55: After his degree in biochemistry, Wolf considered medical school, but he had some personal health problems. That’s when, “The evolutionary approach to health/medicine got on my radar.”
7:28: Plus, he says, “Academia seemed to move at glacial speeds.” “Around 2000-2001, I found this weird thing called Cross-fit. I opened a gym, and it happened to be the first cross-fit affiliate in the world, and I opened a second one (the fourth in the world) … That was kind of the medicine that I wanted to practice. I got to talk to people about sleep, food exercise; and build community.”
9:15: Wolf describes his entry into evolutionary medicine: He was vegan, he was not sleeping and he had moved to Seattle, into a tiny basement where he didn’t see the sun for several months. He had a lot of gastro-intestinal problems, as did his mother, whose rheumatologist told her she was allergic to grains, legumes and dairy.
10:47: Around 1998, Wolf learned about the Paleo Diet through the work of Arthur De Vany and Loren Cordain (who would become Wolf’s mentor). Lauren had written a paper called “Cereal Grains: Humanity’s Double-edged Sword.” (http://www.directms.org/pdf/EvolutionPaleolithic/Cereal%20Sword.pdf)
12:00: Dawn asks about the “contemporary collision between foods we’re wired to eat and what we find on the shelves of local supermarkets.”
12:15: Wolf responds: “We’re set up for failure. I half-jokingly say that if you live in this modern environment and you’re not diabetic and broken, then you are kind of screwing up. You’re not paying attention to your evolutionary history.”
12:45: “We have limitless caloric input. We don’t need to expend effort to obtain these items. We have limitless palate options.”
15:00: Wolf’s short definition of the Paleo Diet: “You’re generally not eating a much in terms of grains, legumes, and dairy. You eat everything else: meat, fruit, roots, shoots, vegetables.”
16:27: He also cautions against the trendy uptake of the diet: “Paleo became this thing where people were asking: ‘Is this Paleo or not?’ instead of ‘Is this a good item for me?’”
17:00: Wolf decries the use of the term “Paleo,” which was used early on in the anthropological literature to describe the diet.
17:25: Wolf says that he has been low-carb for a long time; he currently eats 100-150 grams of carbs a day. “I’ve really enjoyed ketogenic diets in the past. That’s where I get my best cognition from.”
17:35: “I am playing again with a ketogenic diet again because I am being leaned on by folks like you (Ford) and some other people to see if I can fuel my Brazilian Jujitsu activity.”
17:49: He can eat lentils, beans and corn…but not gluten. “I am highly reactive to gluten and gluten-like grains.”
18:45: Wolf discusses the role of genes in what we ought to eat, and the gut microbiome in modifying those genetics…He cites the studies of the Weizmann group in Israel, in which 800 people were given a sub-cutaneous glucose monitor and then fed a battery of meals. “The glycemic response was all over the map.”
20:00: “One person would eat a banana and have virtually no blood glucose response …Another person would eat a banana and get into nearly diabetic ranges… It’s clear in my mind that there’s massive variation in folks, and that a one size fits all approach is really, really problematic.”
21:00: Ken comments: “It would be surprising to me if Northern Europeans and Kitavans would both be ideally suited to eat exactly the same diet, particularly for genetic reasons, but also for gut microbiome reasons.”
21:50: Dawn asks if anyone has looked at the impact of ancestral diets on people doing manual labor jobs or professional athletes—since our ancestors were more active than we are.
22:00: Robb answers that most of the studies have been done in disease populations, such as people with cardiovascular disease, Type-2 Diabetes, insulin resistance or stage I/II renal disease.
23:43: “Both coaches and elite performers tend to be ahead of academia in empirically figuring out what works well.”
23:55: The Paleo way of eating has reached the Navy’s Special Warfare community.
25:05: “In college, most of us had some sort of horrific diet like pizza and beer for months on end and it didn’t kill us, so my greasy car salesman pitch is why don’t you give it [the Paleo diet] a shot for a month and see how you look, feel and perform; do blood work before and afterwards and see how it works.”
26:30: Dawn asks if an obese individual following a cleaner, healthier diet is enough to shift his/her phenotype to a healthier place.
27:11: “I think for the optimum human experience we need some sort of vigorous physical activity at least occasionally.”
28:00: “Ketogenic diet plus fasting can actually mimic a lot of the physiological processes that we see with exercise, but I’m not sure how much mileage we can get out of that. There’s some indication that a ketogenic diet and intermittent fasting can enhance certain elements of our metabolism, like mitochondrial density [along with] pro-apoptotic and autophagy benefits.”
28:50: “We need periods of relative abundance and some scarcity, and that is then sending signaling that is possibly most consistent with health and longevity.”
29:10: Wolf discusses who food and the metabolic byproducts of food and exercise are often signaling molecules. “There’s an expectation for a certain type of cadence and beat to our physical activity and nutrient intake, and if we get out of step with that, then I think that we’re pre-disposing ourselves to a transcriptome that may be pathogenic at some point.”
30:00: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
31:15: Dawn asks about studies comparing unprocessed, whole-food diets to comparable Paleo diet.
31:46: Robb cites a Lynda Frassetto study comparing the Mediterranean and Paleo diets. (http://jn.nutrition.org/content/early/2016/04/20/jn.115.224048.) The two groups were fed at a level so they would not lose weight. It was hard to get the Paleo group to eat enough food so they would not lose weight. Absent weight loss, they saw dramatically improved blood lipids and systemic inflammatory markers in the Paleo diet group.
34:26: Dawn talks about being vegetarian for 22 years, an emotional decision rooted in growing up on her grandparents’ farm during the summer and being uncomfortable eating what had been killed and that she had helped raise. “When I was seventeen, my grandfather told me who I was eating at the dinner table. So I called it quits…. But a lot of us are interested in the Paleo diet.” She asks about recommendations for vegetarians interested in the Paleo Diet.
36:08: Robb says, “If we’re doing eggs and dairy, it really is pretty easy to make that work. Properly prepared legumes are a great background, primary energy source; lots of coconut, coconut oil; cheese and butter.”
37:38: One possible caveat for those on vegetarian diets is to avoid a monochromatic dietary pattern. We need to be better about rotating foods in and out, like eggs.
39:50: At Wolf’s house, he does 90 percent of the cooking. His wife, who is Italian, was vegan when Wolf met her—and he impressed her with his cooking. She switched to his diet.
41:22: We really don’t eat much in the way of gluten. Many people think it’s just a fad. I’ve spent twenty years studying this from an immunological perspective, and there are a lot of folks that benefit from gluten free.
42:05: The preponderance of what they eat is sweet potatoes, fruit, fish, seafood; both of Wolf’s little girls eat homemade sauerkraut, homemade kimchi; liver.
42:22: His kids’ dentist has noticed that the kids have a lot of space between their teeth—and broad jaws, a notable phenotypic expression. This likely means they won’t have crowding of their teeth. Wolf attributes this to their nutrient-rich diet. On the contrary, lower nutrient-dense foods cause a shortening of the dental arch and crowding of teeth. “That would kill us were it not for modern dentistry.”
45:10: Still, his kids express the same attraction to sweet foods as everyone else. “We have to find some way …so that we aren’t on the losing end of food intake.”
45:48: Ken comments that the neuro-regulation of appetite is currently of huge interest and asks Rob to discuss it.
46:11: In the last fifty years, there have been a lot of macro-nutrient wars such as those between high and low carbs. “At the end of the day, what we want to see is some ability for people to eat an appropriate amount for their energetic needs and not much more/less. [It] boils down to the neuro-regulation of appetites.”
47:10: “The state of ketosis is incredibly satiating, and seems to be disproportionately so relative to caloric intake.
47:22: “One takeaway that I would love for folks to noodle on is that within medicine and dietetics, there is only one disordered eating that they acknowledge, and that is trying to limit palate options in some way. If you show up eating a big gulp and Twinkies — you are good to go.”
48:00: In every study that’s ever been done comparing the American Dietetics recommended diet with the vegan diet, or the high protein diet, etc. … the diet that fails consistently is the moderate, don’t-exclude-any-food-groups diet.
49:42: Ken asks Robb how he felt in ketosis initially, post-adaptation period.
51:22: Robb says when he first clicked into ketosis, around 1998, “It was amazing. I had incredible mental focus. I could go hours or even days without eating. It just didn’t phase me at all.” He was also very active at the time, doing gymnastics and Brazilian Capoeira.
54:30: Robb says exogenous ketones are “reasonably impressive.” Ketone salts give him GI upset. He is getting ready to play with ketone esters. He mixes MCT oil with soy lecithin and nut butter (as a carrier.) That mitigates his GI problems.
59:30: Robb comments on the cultural tendency to over-train. “We hold elite athletics on a pedestal. We assume their training should be emulated, and I haven’t seen that to be the case. And I see a lot of people break themselves as a consequence of that. Endurance athletes especially are neurotic about training.”
1:01:40: Ken comments: “Marathon running has been a sacred cow, and a symbol of personal virtue…We hear more and more of negative consequences associated with long-term, extreme endurance activities.”
1:04:12: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
1:04:50: Robb used to recommend high dose Omega 3 supplements. Now he recommends getting as much of it from your diet as you can, with deep water fish that are smaller on the food chain such as mackerel and sardines.
1:06:40: He says Omega 3s are “highly reactive poly-unsaturated fats: if we dump that into an already inflamed individual, that could be a disaster.” In certain people, other issues need to be tackled first before using Omega 3s as an adjunctive therapy.
1:08:30: Ken says nicotine gum seems to provide focus and a productivity boost, especially during activities demanding focus such as writing a book.
1:09:09: Robb started researching nicotine when he was giving talks on sleep, nutrition, alcohol and nicotine for the Navy SEALs. He found that nicotine enhances dopamine status; and is beneficial for gastrointestinal issues. The culprit (i.e., cigarettes) is the delivery system.
1:11:03: Robb tried nicotine gum, about which he says: “It was a whole other layer of peeling back the fog, and the focus. Plugging into the matrix for 45 minutes to an hour. I shared this information with the SEAL community. The flight docs just wanted to barbeque me alive.”
1:11:54: He recommends lozenges and gum, not cigarettes.
1:13:55: Dawn says her dad smoked when he did fine-scale modeling.
1:14:27: Ken comments that nicotine is among the most addictive drugs in common use. Nicotine has a 90 percent addiction liability (90 of 100 people would become addicted). Opiates are 50 percent; and alcohol, about 10 percent. With nicotine, there is not much of a list (unlike for opiates and alcohol) of societal or personal health hazards.
1:16:45: But one should probably be cautious regarding nicotine in cold weather. Robb once did long bow hunting in very cold weather and chewed nicotine gum, and because of the vascular constrictive effects, he went from being completely comfortable to his hands and feet turning into blocks of ice.
1:17:17: If you’re prone to Raynaud’s disease, nicotine would not be a good idea; or in a situation where your extremities need to be warm, it’s not a good idea.
1:18:04: Robb talks about the Lazy Lobo Ranch and the work of Allan Savory, who developed a process to reverse desertification by using smartly controlled grazing animals.
1:19:15: Robb moved to a three-acre ranch in Reno. Comments that Nevada used to be a giant grassland.
1:20:58: He uses a mob grazing technique with electric fencing. Because animals are bunched up tight, they compete to eat everything. The before/after photos of this piece of desert land are just stunning.
1:23:14: Allan Savory makes the point that one third of all the land masses on the planet are grasslands; this is amenable for growing grass/animals, and we’ve shied away from using these areas in these ways.
1:24:15: “I think there’s a real opportunity to produce lots of food, address some soil carbon issues, and heat sinks and water utilization. When you re-establish these grasslands, the water doesn’t just run off; you don’t get flooding. It actually re-fills aquifers.”
1:25:11: Ken says, “Allan Savory is a person that more people should know about and pay attention to.” (http://savory.global)
1:25:49: Robb’s new, upcoming book, “Wired to Eat,” is looking at the evolutionary biology story again. “The thing that seems to pop up again and again is sense of guilt and failure of morality around eating.” He diffuses that in the front of book.
1:28:24: “My hope is that both on a cognitive level and an emotional level people can plug into this and understand: ‘I’m not a failure because this stuff is hard.’” The back part of book contains a 30-day re-set for the neuro-regulation of appetite and getting your insulin in line. The final chapter is titled ‘Hammers, Drills and Ketosis: The Only Tool Your Doctor Will Never Use’. A carpenter wouldn’t argue about whether to use a drill, saw or ax — they each have specific and well-appreciated purposes. Ironically in medicine, the use of ketosis and fasting as tools is a controversial topic.
1:30:20: The book will be out in March or April, 2017. Amazon is taking pre-orders. (http://amzn.to/2hqfJJE)
1:30:46: Dawn asks about the genesis of Robb’s popular podcast. At first, the podcast was about answering questions from the audience and over time he shifted the podcast to an interview format. Currently, Dobb is thinking about adding a “news round-up” section to the podcast.
1:33:19: Dawn and Ken thank Robb for the interview and his recent IHMC lecture, available for viewing at: https://www.youtube.com/watch?v=qga4A3vnXmg

Episode 26: Richard Moon discusses deep-sea and high-altitude medicine
Dr. Richard Moon had an unusual inspiration to practicing medicine: a television show, in black and white, entitled, “Medicine in the ‘60s.” He remembers being blown away by watching live surgeries performed on the show. This eventually led him to a career in the operating room—not as a surgeon, but an anesthesiologist.
Like many STEM-Talk guests, Moon wears many hats. In addition to being a physician, he is a renowned researcher in the hyperbaric and diving medicine. He is currently a professor of anesthesiology and medicine at Duke University, and the Medical Director of Duke’s Center for Hyperbaric Medicine and Environmental Physiology. http://anesthesiology.duke.edu/?page_id=828766
In this episode, Host Dawn Kernagis, herself a rising research scientist in undersea medicine, as well as a highly experienced diver—earlier this year, she was inducted to the Women Divers Hall of Fame—talks with Moon, one of her mentors. Dawn met Moon when she participated in one of his research projects as a diver, and she went to him with research ideas as a potential research intern. She eventually became one of his graduate students at Duke University.
In this lively and informative mentor-mentee discussion, Dawn and Moon talk about the history of hyperbaric medicine, including the establishment of Duke’s world-renowned Center for Hyperbaric Medicine and Environmental Physiology. They talk about medical conditions that can occur in deep sea diving, such as high pressure nervous syndrome and immersion pulmonary edema, as well as high-altitude sickness.
Moon shares insights about his experiments in both high altitude and deep sea medicine, as well as his own expedition in climbing Mount Everest.
Check out Moon’s home page at Duke: http://anesthesiology.duke.edu/?portfolio=richard-moon-md ; as well as his lecture at IHMC last January: “From the Ocean Depths to the Mountain Tops: How Do Humans Adapt?” http://www.ihmc.us/lectures/20160121/
00:15: Dawn introduces Ken and describes Moon as a world-renowned physician and researcher who works in hyperbaric and diving medicine.
00:40: Dawn says she was “very lucky to have Dr. Moon as a mentor.” She participated in his research projects, as a diver. She then went to him with research ideas, and he accepted her as a graduate student, and he’s been a mentor and colleague ever since.
1:45: Ken reads a five-star iTunes review from “GTG2010” called “Exploding Kid:” “Dear STEM-Talk, I like your show. The super telescope looking at asteroids is cool. I like it so much I’m going to explode. Love, Griffin, age 6.”
2:38: Dawn runs through Moon’s bio. He holds an M.D. and a C.M. from McGill University in Canada, and a Master’s degree in biomedical engineering from the University of Toronto. He is a member of the Royal College of Physicians of Canada, as well as the American Board of Internal Medicine. He has authored hundreds of peer-reviewed publications.
3:48: Dawn welcomes Moon to the podcast.
4:06: Moon describes what sparked his interest in medicine when he was in high school. He watched a television show, in black and white, called “Medicine in the ‘60s.” “It showed operations. It was mind-blowing, so I decided that I had to go into medicine.”
4:49: In medical school, Moon’s first interest was in pulmonary medicine—simply because in the first-year lecture series on organ systems, the one on the pulmonary system was the best. Yet, he felt compelled to do something different and took a couple of years off to study biomedical engineering.
6:20: Moon went to Duke University with a fellowship in pulmonary medicine as well as an opportunity to undergo scientific training in diving physiology. One of his mentors, Enrico Camporesi, encouraged him to go into anesthesiology.
7:20: “Eventually he [Camporesi] won me over. That’s where I am today.”
7:46: Moon’s interest in diving physiology initially came from the television program “Sea Hunt.” He also read the Jacque Cousteau books, which talked about decompression sickness and carbon monoxide poisoning. “When it came time to figure out where I was going to go after internal medicine, since Duke had this mega lab, the best in the world, and some leading lights in diving physiology, I just couldn’t resist.”
8:48: Dawn comments that the F.G. Hall Laboratory, which is now part of the Center for Hyperbaric Medicine and Environmental Physiology “is considered to be one of the best and prestigious environmental physiology labs in the world. Especially back then, there was research being done that wasn’t being done and hasn’t been done anywhere else in the world.”
9:18: Moon talks about the history of the lab. People have always asked, ‘How did this undersea lab get to be in a place that isn’t near the ocean?’ “It was a confluence of interests at Duke at the time. Herb Salzman was a pulmonologist interested in diving; F.G. Hall had been of an earlier generation and interested in altitude physiology; a surgeon named Ivan Brown was interested in cardiac surgery under hyperbaric conditions. This was an era before heart and lung machines were developed. So, the notion of drenching the tissue with oxygen was very appealing – if you could hyperoxygenate tissues in a hyperbaric chamber during surgery, you would have longer available time to perform surgery.”
11:07: One of the chambers at the Duke Hyperbaric Center was built as a hyperbaric operating room. Enough money was put together to create the facility. By the time the chamber was open, heart and lung machines were in place, so the whole concept of surgery in a hyperbaric chamber was out of date; however, the Duke Hyperbaric Center remained a nice facility to treat patients.
12:03: In 1968, after the nuclear submarine disaster, the Navy realized that it didn’t have a facility to do deep diving. So, Saltzman was asked to develop a deep diving program for salvage operations at 1000 feet of seawater.
12:35: In the late ‘60s through mid-70s, there was a perceived expiration of oil. Several labs were created around the world (two labs in the U.S. (University of Pennsylvania, Duke), one lab in Europe, and one lab in Japan) to study the physiology of humans during exposure to relevant depths for oil exploration (1000-2000 feet). Several problems were identified for humans at these extreme depths, including high pressure nervous syndrome (HPNS, where a diver gets tremors, difficulty standing up, nausea, vomiting).
14:08: Part of the Duke endeavor, called the Atlantis Dive Series, was to work out how HPNS could be overcome. One idea: to put a little bit of narcotic gas (nitrogen) in the helium-oxygen breathing mix; it was felt this might offset HPNS. It did work, but it had other effects such as an increase in breathing gas density.
15:00: With an increase in gas density, did lung work to provide enough oxygen to the tissues and remove carbon dioxide? Duke was the first to measure blood gases, such as oxygen, and pH under those conditions. They found that the lungs actually worked pretty well breathing a denser gas, contrary to common belief. The Duke researchers provided the boundaries on what the lungs could do under those circumstances.
16:15: To get to 2,000 feet, it takes several days: one way to offset HPNS is to add nitrogen to the mix, Decompression is slow – it takes 2-3 weeks to get people to the surface from depth due to decompression issues.
17:10: The Atlantis Dive Series conducted four experiments—each with three male study participants living inside the chamber. “They were stuck inside. If one of them had developed an acute illness, say appendicitis, it would have taken us three weeks to get him out.” They were also in tight quarters and slept in bunks in layers. Food had to be locked in.
18:10: Our part of the experiment was to have each person exercise on an exercise bicycle. The other guys had to place an arterial catheter in the wrist. The blood samples then had to be analyzed in a blood gas machine. “It was an adventure not only in biology, but also in engineering. “
19:10: Dawn compares it to telemedicine, and asks about the psychological issues of the men in the experiment.
19:40: Moon says there were areas of friction: “Three is worse than two or four because one person is always the fall guy. It was a challenge. They were carefully chosen, and they were up to it, and ultimately did a great job.”
20:00: Dawn mentions linking to Duke University’s F.G. Hall Center: http://anesthesiology.duke.edu/?page_id=1061
20:48: One of the benefits of Duke’s chamber is that it is actually within a hospital. “We can expose people to high or low pressure to simulate altitude and have all the accoutrements of medicine available.” Moon adds they’ve been able to do some very interesting studies. He mentions one, led by Dr. Jake Freiberger, which looks at nitrogen narcosis and any cognitive effects of additional carbon dioxide.
22:21: Another study is looking at immersion pulmonary edema, which is basically “drowning from the inside,” or when divers’ or swimmers’ lungs fill up with fluid. They’ve shown: People who are susceptible to pulmonary edema have higher pressures for a given amount of exercise than others. This issue reached public consciousness because Navy Seals have experienced this malady. “These are young, healthy, exceptionally fit individuals who start coughing up fluid/blood in the middle of what would otherwise be a normal swim.”
24:00: Moon explains that the hearts of people susceptible to pulmonary edema are normal, but just a little bit different. Their left ventricle is a little stiffer than normal when the heart fills up with blood. Therefore, in order to fill it, the pressure is a little bit higher; adding to that is extreme exertion, which raises the pressure even higher. That’s enough to break the barrier between the blood within the lung and the air spaces within the lung, and cause fluid to leak.
25:18: To deal with it, a lot of people (including the Navy) have recommended pushing fluids. Dehydration is a bad thing; overloading with fluid tends to make the problem worse. Some potential drugs could be taken.
26:10: Navy SEALs tend to get it; and triathletes—especially during the swim part of the race – can also experience it. “Triathletes are go-go people; want to win the race. They often see it, not as a health problem so much as something that just slows them down.”
26:54: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
27:40: Problem with altitude boils down to one thing: low levels of oxygen. Because pressure is lower, the partial pressure of oxygen is lower as well…low oxygen has a variety of effects on human physiology. People who go to high altitude often experience acute mountain sickness, which is nausea, vomiting. It can cause high altitude cerebral edema or high altitude pulmonary edema, where lung fill up with fluid.
29:07: If you go to 10,000 feet and then exercise, you realize at altitude you really can’t do it as well as you can at a lower altitude (e.g., you are short of breath). One of the mysteries of altitude is people who have lived there, such as Sherpas…on Moon’s trek to Mount Everest, they were continually surpassed by Sherpas with 80 kilos on their back. They were small guys—150 pounds at most.
30:50: On their way to Mount Everest, their blood oxygen saturation started off in the 70s when their place landed; they were often down in the 60s. If you ask the average physician what would happen if blood oxygen is in the 60s, they would say brain damage. It’s also difficult to do field research. On the other hand, you can do things in the field that you can’t do in a lab-based facility. “It’s always a balance, and you get incremental pieces of information from each type of research.”
32:27: Moon mentions a study that was propelled by John Andrews, a Green Beret before medical school, who had experienced altitude issues. They studied a new drug, called Riociguat (for people for pulmonary hypertension); they are interested in whether this drug would increase exercise performance at altitude.
33:50: They found that pulmonary pressure did go down; the drug worked as advertised; but, unfortunately, it didn’t change exercise performance or improve oxygenation. Had it worked, it could have been a very useful drug for special forces deployed in mountainous areas throughout the world.
34:40: Moon discusses hyperbaric oxygen therapy, calling it “essentially a dive in a hyperbaric chamber breathing 100 percent oxygen at double the atmospheric pressure.” It has therapeutic applications for diving injuries and carbon monoxide poisoning. You can wake people up more quickly, prevent long-term complications, and make people feel better very quickly. It can also be used to treat gas gangrene—an infection of soft tissues that is highly lethal. Hyperbaric oxygen facilitates the killing of those organisms. It is also therapeutic for healing wounds in people with atherosclerosis and diabetes (related foot injuries).
37:14: Moon talks about career paths for people interested in studying diving or high-altitude medicine. He says there are several routes: one is doing expeditionary medicine in the Armed Forces. Another is going into a related field such as surgery, internal medicinal pulmonary medicine or anesthesia, and using altitude medicine as a sideline.
38:25: To do it full-time, Moon suggests programs at Duke or the University of Pennsylvania; or the military.
38:48: Dawn adds there are close ties (and opportunities) between both academic and military research centers.
39:30: Moon says he has read a lot of books written by people (like Jacque Cousteau) and many of the mountaineers. In terms of the medicine of diving, the book that really got him into it was edited by Peter Bennett and David Elliot. It’s a classic called “The Physiology and Medicine of Diving.” Fred Bove also edited a book called “Diving Medicine” for several editions.
40:41: Moon talks about his own expedition to Mount Everest, first noting that during the earliest “Hillary” expeditions, they had to walk from Katmandu. Now people fly into Lukla (in Nepal), “the most dangerous airport in the world. There’s no second chance for the pilot. You’re flying in with wingtips close to mountains…the runway goes cliff, runway, cliff…You have this little landing strip, so there’s no way to turn the aircraft around if you miss the landing.”
42:00: “The first day, you have to go down 1,000 feet, and then up 1,000 feet. At the end of that day, you think: ‘If this continues, I don’t think I’m going to be able to do it.’ But the scenery is spectacular: It starts off tropical. [Then it becomes] almost like a hike in a U.S. National Park. The higher you go, eventually it becomes barren, as trees drop away. Eventually it is snow and ice. By the time you get to base camp, it’s totally snow. But it also has a huge diurnal variation in temperature. When you wake up, you’ve gone through minus twenty degrees Fahrenheit. By lunchtime, you’re sitting with very little clothing on. Once the sun goes down behind the mountain, it becomes very cold again.”
43:36: “The Sherpas are delightful people. There is usually one room only that is warm; with a stove in the middle burning yak gum. Food is pretty good. “Despite eating like crazy because you’re hiking, and you’re hungry, we lost weight … It seems to be an altitude effect.”
45:00: Dawn observes that whenever they bring the tools of the trade into the field, whether deep divers or free divers, there’s always always a lot of interest peaked in terms of the research being done.
45:31: A British group had a full-blown lab at 12,000 feet at Namche, and another group had one at base camp: they were doing muscle biopsies, exercise tests…that data is still being crunched. “Climbing community is like the diving community: it’s a very elite group of people. Everyone’s got their own theory on how to do it, how best to prepare for it. There’s a relative lack of science because the experimental conditions are so tough.”
46:25: Dawn thanks Moon.
46:37: Dawn commentates on being able to interview her mentor, and Ken calls Moon “a broad and fascinating fellow.”
46:50: Dawn and Ken sign off.

Episode 25: James Briscione discusses the art & science of food & flavor
James Briscione’s stellar cooking career began humbly: As a teenager, he washed dishes at a now defunct restaurant (named Jubilee) on Pensacola Beach. He quickly rose through the ranks, at age 24 becoming the chef de cuisine at the Highlands Bar and Grill in Birmingham, Alabama, which is considered one of the best restaurants in the South, and later the sous chef at the prestigious New York City restaurant Daniel.
Today Briscione, who lives in New York City, is a top-tier chef, author of three books on cooking, director of culinary development at the Institute of Culinary Education, and a three-time champion on the Food Network’s cooking competition series Chopped. So what is he doing on STEM-Talk, you might ask? Briscione is also versed in the science of cooking and flavor. He partnered with IBM in creating the “Chef Watson” project. This computer-based program generates hundreds of novel flavor combinations based on the compatibility of chemical compounds in food.
In this episode, Briscione talks with IHMC Director Ken Ford and IHMC Chef Blake Rushing about the art and science of food, and Briscione’s career as a chef. Briscione’s three books include: “Just Married and Cooking” (with his wife Brooke Parkhurst): http://amzn.to/2eDIpJD; “Cognitive Cooking with Chef Watson”(http://amzn.to/2g04Kq0); and “The Great Cook: Essential Techniques and Inspired Flavors to Make Every Dish Better.” (http://amzn.to/2elhlDr). He also has his own, new television show on the Food Network called “Cooking with Dad.”
Briscione, his ideas on cooking and his own culinary creations have been featured in the New York Times, NPR, the New Yorker, Time Magazine and hundreds of other media outlets throughout the world. Briscione’s recent talk at IHMC, entitled “Who teaches the cooks to cook?” can be viewed at http://www.ihmc.us/lectures/20160811/
Dive into this delicious interview—an entertaining and informative conversation between three foodies.
00:32: Ken introduces Blake Rushing as the guest co-host of this episode of STEM-Talk. Rushing is IHMC’s chef, as well as the owner of Union Public House in Pensacola.
1:00: Ken introduces James Briscione as, “Working in the boundary spaces between the science of food, science and taste and even AI systems, such as Chef Watson.”
1:49: Dawn reads 5-Star iTunes review from “Beautronical:” “I am continually enthralled by the variety and depth of ideas presented here. Also, it is rare that one finds great minds matched by great voices. Given the ketogenic bent of certain interviewers, perhaps mellifluous is the wrong term, but I’ll use it nonetheless.”
4:42: Ken introduces himself and Blake Rushing as hosts of the interview; and then welcomes James to the interview.
5:05: James says he remembers the food made by his Italian grandmother. Among them: chicken cacciatore (although the mushy carrots bugged him.) The “greatest mashed potatoes… Sunday red sauce; sausage and meatballs loaded down with pecorino cheese.”
6:55: “True learning doesn’t often happen until you’re in the kitchen every day,” Briscione tells his students. He didn’t go to culinary school, but has been in the kitchen since he was 16.
8:15: At 16, he was a bus boy washing dishes for two restaurants: fine dining upstairs and casual beach dining downstairs.
9:33: As a teenager and at the beginning of college, Briscione thought, ‘There’s no way I am going to spend the rest of my life in a kitchen.’ He was working on a degree in sports medicine in Birmingham, and worked summers at the restaurant [in Pensacola]. After his second summer, something clicked: he changed his course of study from sports medicine to nutrition.
11:00: James knocked on the back door of Bottega Cafe [in Birmingham] http://www.bottegarestaurant.com/cafe/ and said, ‘I want to work here.’ He got a job as pizza maker with a wood-fired oven. He remembers stretching the dough and putting the toppings on it, then handing it off to the next guy. “That and lugging firewood to store underneath giant hearth oven.”
12:54: Briscione talks about working with Frank Stitt, owner and chef at the Highlands Bar and Grill in Birmingham http://www.highlandsbarandgrill.com , whom Briscione calls “a great leader.” He fosters a great sense of family in all of his restaurants; his cooks go and work in the farms for harvesting veggies. Briscione attributes his success to the fact that, “I showed up everyday. I was there, and I was there early.”
16:08: Briscione won on Chopped three times. “I always just try to do a little bit more than everybody else. I always want to out-hustle the other guy.”
17:05: He recalls one Chopped experience: “It’s insanely hot in that kitchen; four stoves; four ovens. No hoods pulling the heat away. It’s a warehouse essentially. I was mincing an onion as fast as I could. You could hear the judges say, ‘It seems like Chef James already has something’…I heard that; everyone else heard that. I at least gave the impression that I knew what I was doing. I never touched that onion.”
19:30: Another theme of Briscione’s career has been “being in the right place in the right time.”
20:00: Ken discusses fat as a taste receptor, and one of many taste receptors that humans have. Our tongues have receptors for detecting fat; he asks Briscione if he considers fat a taste or an oral sensation, or both.
21:00: Briscione says that he thinks it’s both.
21:36: “The tongue is a detector of nutrients and toxins. All of these different nutrients that are essential—I think we have receptors for all of those.”
22:10: Ken remarks that people make a distinction between having a receptor and taste; sensitivity of the fat receptor is modulated by a protein called CD36. People vary in their ability to sense fat, and it’s related to the level of that protein.
23:55: Ken adds that “The Physiology of Taste: Or Meditations on Transcendental Gastronomy,” by Jean Anselme Brillat-Savarin, and translated by M.F.K. Fisher) (http://amzn.to/2f4QkQw) is among the greatest works on food…largely because of the emergence of the wonderful notion of flavor.
24:24: Briscione on taste: When you take a bite of cake, you start to identify it because you smell it. It hits your tongue, which loves the sugar. As you begin to chew, the volatile molecules make their way to the back of the throat and cheeks.
26:00: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
27:00: Chef Watson sifts through data in a way that puts new flavors together. (https://www.ibmchefwatson.com/community)
27:48: Examples include salmon and licorice; pineapple and blue cheese.
29:00: Watson also understands different cultural ingredients.
30:22: Briscione talks about his favorites: gently cooked (sous vide) apples, surrounded by olive oil and fresh sage. Olives and cherries (a jam out of that—the best condiment for a cheese plate.)
31:50: “Mushrooms, strawberries and chicken didn’t make sense. But it works really, really well…. This [Chef Watson] is a great thing: it shows the true collaboration between man and machine.”
33:37: One of Briscione’s favorite compounds: 4-methylpentanoic acid, which is found in pizza. “We have scientific proof that pizza is delicious.”
35:02: A strawberry has 383 compounds that make up the smell of that strawberry; they may not be the ones we recognize right away. The body is still sensing all of those. A lot of matching happens.
35:40: Mesifurane is a key compound in strawberries; on its own, it smells like baked bread.
36:51: Ken and James discuss Chef Watson as a kind of “cognitive orthotic” enabling increased creativity and efficiency in the kitchen.
37:10: “Creating recipes usually means sitting down with a stack of cookbooks; it’s a long and complicated process, and I liken it to decision fatigue.”
38:48: Chef Watson removes this burden by providing a list of ingredients that will work together, so that chefs can focus on the creative process of putting those ingredients together.
39:40: Briscione talks about using the Golden Ratio in cooking; just as in painting, there are those born with an intuitive understanding of the proportionality in the Golden Ratio, and those that learn it. “[Chef] Watson helps you get to that point: I can find hidden pattern in food that helps me be better at what I do.”
40:40: Ken comments that the Golden Ratio is seen elsewhere, such as in mathematics, with the Fibonacci sequence.
41:56: “One of the strongest pairings is between olives and citrus: they have about 60 percent of compounds in common. Wherever olives grow, so do citrus fruits.”
43:27: In Briscione’s upcoming book, he features a lemon curd dessert with an extra olive oil (not butter) finish. The crumble top is a sort of streusel made with oil-cured olives, a bit of rosemary, brioche crumbs and sweetened almonds. “It’s a beautiful savory-sweet interesting dessert.”
44:37: “Computational creativity can break through the bias/blindness in the cultural underpinnings of cooking.”
45:15: In the Watson method, “We’re looking at ingredients with a complete blank slate.” For example, in looking at a tomato, break free from the basil. “Erasing those pre-conceived notions was key to project.”
47:30: More information on Chef Watson can be found at: www.ibmchefwatson.com.
48:40: Briscione talks about sous vide cooking: ‘under vacuum’ is the literal definition. It is very precise low-temperature cooking held at the exact degree of doneness that we want [whatever food] to be.
52:30: Ken talks about how when he was in the Navy, in the late 70s and 80, he invented a super crude version of sous vide. He vacuum-packed food in the same machine used for electronics. It was “seal-a-meal,” but much better than the green mess-hall food.
54:10: Briscione says the next thing in cooking will be precision temperature control, such as Control Freak (an induction top) from PolyScience Culinary; Combi ovens; and CVap (Controlled Vapor Technology) ovens.
56:15: Briscione talks about hydrocolloids or gums: “People have had them in their kitchens for as long as they’ve lived.” Examples include flour and corn starch, or anything that forms a gel in the presence of water. Xanthan gum is the gateway drug to hydrocolloids. Others are derived from seaweed.
1:00:00: Ken comments on the irony of the public perception that chemicals in food are a bad thing, when food is made up of chemical (compounds.) He shares a funny anecdote about walking in and out of popular restaurant in Atlanta that boasted of no chemicals in their food.
1:01:36: Ken asks Briscione what he eats, and he says, “So far, a muffin and coffee today.” As for Briscione’s favorite foods: “Any piece of the pig is going to make me really, really happy.”
1:02:15: “I can eat a large watermelon by myself in minutes. Vegetables make me really happy.”
1:03:00: A favorite recipe using modernist cooking techniques: Vegan ramen broth, with smoked tofu and dried Shitake mushrooms, ginger, garlic and scallions. With soy sauce and pork.
1:04:15: His own favorite restaurants: The NoMad in NYC: for their “wonderful vegetable entrees. They take a single ingredient and present it to you on the plate in three or four forms.” He’s also a fan of the Gramercy Tavern.
1:06:10: His favorite daddy-daughter date is Dominique Ansel’s bakery in NYC.
1:07:00: When Briscione and his wife Brooke Pankhurst (also a Pensacola native) come home to the South, they enjoy good fried seafood such as fried mullet, snapper throats and mullet backbones — as offered at Chet’s Seafood.
1:09:44: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
1:10:25: Briscione talks about his first cookbook, “Just Married and Cooking” (http://amzn.to/2eDIpJD): “The thing I love about that book is that I can open to any page in that book, and point to a recipe, and tell you a story about the first time we cooked that.” He characterizes the recipes as “everyday meals for ourselves.”
1:11:43: Talking about his book, “The Great Cook,” (http://amzn.to/2elhlDr) which came out last year: “It’s really kind of all these great dishes that all cooks should know.” It reads as if Briscione, a great cooking teacher, is sitting there at the kitchen counter and coaching them through dishes. Plus, it has really beautiful photography.
1:13:34: Also last year, the Chef Watson cookbook came out, “Cognitive Cooking with Chef Watson:” http://amzn.to/2g04Kq0. Briscione talks about one recipe: Spanish almond crescent, conceived as a pastry for a breakfast meeting. “I love Spanish food, and Spain. The almond is a seed for Watson to build the flavor pairings off of: saffron, black pepper, cocoa and coconut milk.”
1:16:30: Ken and Briscione talk about their favorite places in Pensacola, including Joe Patti’s fish market, and Chet’s and Jerry’s Drive-In.
1:17:28: Ken says: “When I have people in town, from NYC or San Francisco, food writers or chefs, I don’t take them to our fine dining restaurants. I get an excellent wine and good wine glasses; and we have a whole feast at Chet’s.” Ken’s favorites: marinated flounder or grouper.
1:19:20: Briscione talks about his new television show on the Food Network, “Cooking with Dad:” (http://www.foodnetwork.com/videos/dad-and-daughter-pasta-0251005.html). He describes it as: “What it looks like for a chef to cook at home with his kids…Or what’s it’s like to just put dinner on table every night. Or snack after tap class. Or Sunday morning brunch.”
It includes Briscione and Brooke, their 7-year-old daughter Parker, and 14-month-old son.
1:21:31: Ken thanks Briscione for the interview as well as his IHMC lecture, which gathered well over 300 people and can be viewed at: http://www.ihmc.us/lectures/20160811/
1:21:58: Ken says this episode “this episode combined two of my favorite topics: the science of food spiced with a touch of AI.”

Episode 24: Doug McGuff talks about resistance training, myokines, strength and health
One could say that Dr. Doug McGuff is one of the pioneers of BMX motocross bike racing in Texas. He built the state’s first race track, having gotten hooked on the sport as a teenager in the 1970s.
The sport also triggered a deeper interest in fitness. As McGuff tried strengthen his core for bike racing, he discovered Arthur Jones’ Nautilus training technique and bartered janitorial services for a Nautilus gym membership.
McGuff’s interest and aptitude for studying the body led him to pursue medicine at the University of Texas in San Antonio. He specialized in emergency medicine, was chief resident of emergency medicine at the University of Arkansas in Little Rock, and a staff physician at Wright-Patterson Air Force Base Hospital in Ohio. McGuff is currently an ER physician with Blue Ridge Emergency Physicians in Seneca, South Carolina.
The other side of McGuff’s career is dedicated to fitness, or as he says—helping people never have to go to the ER. Realizing a lifetime dream, he opened up his own fitness facility in 1997 called Ultimate Exercise. The gym is dedicated to the type of high-intensity fitness training using the Super Slow protocol.
In this episode of STEM-Talk, McGuff talks about why this type of exercise is better for the body, safer, and able to prevent age-related conditions such as sarcopenia.
McGuff is the author of three books: “Body by Science: A Research-Based Program for Strength Training, Body-building and Complete Fitness in 12 Minutes a Week,” http://amzn.to/2fy7vKN (co-authored with John Little), “The Primal Prescription: Surviving the “Sick Care” Sinkhole,” http://amzn.to/2fLTBtl (co-authored with economist Robert Murphy), and “BMX Training: A Scientific Approach.” http://amzn.to/2fUhqPd
He is also featured in several YouTube videos on high-intensity training. His recent IHMC lecture, entitled “Strength Training for Health and Longevity,” is available at http://www.ihmc.us/lectures/20160929/.
2:03: Dawn reads an an iTunes 5-star review from “Guy who likes Chipotle,” which is entitled “Interesting and just complex enough.” “STEM-Talk does an amazing job of delivering high-level information on a variety of topics, without making it too complex to understand.”
4:21: Dawn introduces Doug and Ken.
4:47: McGuff says that as a young teen, shortly after getting interested in BMX bike racing, he started working out with his brother’s weights, which was transformational. “It is still the closest thing to magic or a miracle that I’ve ever experienced in my life.”
6:44: Also as a teen, Doug McGuff bartered janitorial services for a membership to a Nautilus gym, where he found a copy of a book by Nautilus founder Arthur Jones (https://en.wikipedia.org/wiki/Arthur_Jones_(inventor)) about training principles. “It was the first book I ever read cover to cover. To say that book changed the course of my life would be a massive understatement.”
8:13: During the summer of 1994, McGuff met Arthur Jones, who greatly influenced his thoughts on exercise resistance training.
12:00: McGuff went into ER medicine because “It was rare to find something that I felt that I had intrinsic talent in. I felt like I functioned very well in that environment.” His career has focused on two things: taking care of people who fall down and get hurt; and trying to prevent it from happening in the first place.
13:00: McGuff talks about being a pioneer of BMX in Texas, as he built the first track there and went back to racing in the late 90s and won the state championship. He also trained some world champion level BMX racers.
14:30: Now he characterizes himself as “a practicing physician so busy with the chronically sick and massively debilitated; the chasm between day to day life and actually thinking about prevention is such a wide chasm that it’s hard to imagine.”
15:00: “I would love to see the day where the commercial says, ‘Ask your doctor if diet and exercise are right for you….’ Instead of whatever pill of the day.”
15:44: McGuff notes the idea of physiologic headroom, which economist Arthur De Vany came up with. “Physiologic headroom is the difference between the least you can do and the most you can do.” See De Vany’s book, “The New Evolution Diet”: http://amzn.to/2ewDOJ8
17:50: “The better part of our lives, in terms of our functional ability, are much less than what they should be.”
18:45: McGuff says that high-intensity interval training is what appears to reverse the biomarkers of aging, according to the literature on the topic.
21:00: In McGuff’s book, “Body by Science,” (http://amzn.to/2fy7vKN), he presents the concept of Super Slow training: lifting and lowering weights very slowly. This protocol emerged out of Nautilus, after Arthur Jones commissioned a University of Florida research study on osteoporosis. Ken Hutchins, an employee of Arthur Jones, was the primary person who defined and popularized the Super Slow form of resistance training exercise.
22:40: The protocol applied to younger subjects resulted in similarly good results.
23:18: More important is the style and intent (of lifting weights). “If your intent is to as intensely and deeply fatigue the muscle as you can…if you start weight-lifting with as gradual a load as possible, and then you just try to lift and lower with high effort, during that initial phase, depriving yourself of initial momentum allows the speed to express itself organically.” In one person, that cadence might be 4 seconds up, 4 down; or 8 up; 8 down. In most people that ends up being 10 seconds up; 10 down.
25:03: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
25:23: Ken talks about the importance of avoiding injury when exercising and posits that Super Slow should be good in this respect.
25:48: McGuff says that he opened his gym, Ultimate Exercise, in 1997. They average 100-120 workouts per week. “We’ve never injured anyone in the facility…. That gives some credit to a slow cadence protocol. You can still get hurt [during a slow cadence protocol] if you don’t observe good biomechanics.”
26:40: The mastermind of “congruent exercise” is Bill DeSimone (https://en.wikipedia.org/wiki/Bill_DeSimone), which is based on using biomechanics to prevent injury.
27:45: At his gym, McGuff tells his trainers: “train ‘em hard as hell, don’t injure anyone, give them adequate recovery.”
29:00: “When we talk about sarcopenia, the population has it in their head that it’s a natural consequence of aging. And it’s not. Sarcopenia is a natural consequence of aging with our modern Western lifestyle injected into the equation.” McGuff notes this did not happen in hunter gatherer societies. “That doesn’t mean modern tech cannot be exploited to leverage those evolutionary adaptations.”
30:10: Age-related sarcopenia occurs when there is atrophy in the type II muscle fibers. “When you recruit muscle to do work, that happens in an orderly and sequential function.” You start with lower-order muscles to do work. Finally, you recruit higher-order muscles, which produce a lot of force output, but they fatigue very quickly. The latter are hard to get at, so you have to produce fatigue in a disciplined fashion.
32:54: An elderly person loses balance because if you go off the vertical plane (not on bone and bone tower), the only way to right yourself is by activating very powerful muscles to correct that posture deficit. “They fall because they don’t have the fast-twitch IIB fibers to yank them back into corrective posture. That’s why they go down like a tree in the forest.”
34:00: McGuff defines exercise as protocolized strength training; disciplined and aimed at achieving a deep level of fatigue rapidly. You can’t stand more than 12-15 minutes of that intensity. You want the minimal effective dose.
35:07: “Most people think of exercise as directly causing the adaption. The exercise produces the stimulus; your body receives it and makes a physiologic adaption.”
35:40: “I make a clean distinction between exercise and activity.”
36:41: “Once you create this physiologic headroom, you want to use it. It’s like having a Ferrari and being restricted to the school zone. It just doesn’t work. That’s not a bad thing.”
37:30: McGuff talks about muscular failure, a term coined by Arthur Jones meaning lifting and lowering weight, and getting to a point where you are trying to lift weight, but it won’t go. The problem is that failure in and of itself does not necessarily define an adequate stimulus. The desired stimulus is a meaningful depth of fatigue, or a substantial reduction in one’s starting level of strength. In the gym, one may reach muscular failure in a particular exercise without reaching an adequate depth of fatigue.
41:25: Ken notes that the Super Slow protocol, as described in McGuff’s book, is performed exclusively on machines, and asks whether this training transfers to what are sometimes called “real world” functional movements and basic movement patterns (squat, hinge, push, pull, carry).
41:50: “When people talk about functional movements and movement patterns, I find that they are fairly ill-defined. Human movement in a functional sense is inherent to our physiology and anatomy. What is necessary for those to express themselves in real world applications is that you have to have a motor that is able to drive the movements of that appendage.”
43:00: “The notion that you have to recreate those functional movement patterns in the gym under load for those functional movement patterns to be expressed out of the gym is a little bit of a false construct. Some of those natural movement patterns, when done under load, are very joint incongruent.”
44:47: Ken and Doug note that confusing “sport” and “exercise” can be dangerous.
44:55: Dawn asks Doug about low intensity training as typically prescribed for the elderly.
45:15: Exercise recommendations for the elderly are often off-base. People making them don’t understand how to invoke high-intensity and low force at the same time. Being physically active at a low level of intensity is part of our evolutionary and biological background. If you get at those IIB fibers, that type of activity expresses itself organically.
46:40: What happens is that you carry out a type of long-term, low-intensity activity that says: This animal is carrying out chronic low-level activity. This becomes interpreted as a negative thing—the stimulus to lose type IIB muscle fibers rather than gain them. “In the long term, you’ve jettisoned one of largest glucose reservoirs in your body, and you have therefore undermined insulin sensitivity.” This accelerates sarcopenia.
47:20: Ken notes that one often sees this adaptation in marathon runners. McGuff, says, “That is why marathon and ultra-endurance athletes look cachexic … because they delivered a biological stimulus to their organism that says these type-IIB fibers are unnecessary for this activity and we need to get rid of them.”
48:12: Dawn asks about exercise while traveling and without good access to good equipment.
48:30: Doug, replies that “We’ve gotten the notion that weights are a necessary part of the equation, and they really aren’t. Through infimetrics, I can provide an intensity of workout that exceeds one with weights. It’s hard to describe in a podcast, but Google McGuff’s name and timed static contraction protocol or infimitric YouTube videos.
50:00: Ken notes that Blood flow restriction training, such as Kaatsu, increases localized IGF-1 levels and sensitivity via accumulation of metabolites, particularly lactate and H (+) and asks if McGuff thinks this type of training is useful.
51:53: Doug discusses blood-flow restriction training, which can produce equal hypertrophy and strength adaptions using a much lighter weight. The theory is that you are concentrating the by-products of metabolism that occur during exertion locally within the muscle, for example the entrapment of local IGF production.
52:46: “I think it is of benefit from several standpoints, one is the fact that it requires less resistance to get an equal result — that increases the safety margin and increases the safety margin for extremely strong people.”
53:37: When you use a slower-cadence protocol, that creates a high degree of sustained muscular tension that produces vascular congestion within musculature that traps metabolites in the same way blood flow restriction does.
54:48: Ken says he’s had good results using blood flow restriction (using the Kaatsu system). He particularly appreciates blood flow restriction training for those with painful or compromised joints given the very light weights. Also, hotels often have a very limited selection of relatively light weights, which are no problem with blood flow restriction.
55:18: Dawn asks whether electrical muscle stimulation (EMS) training might offer promise as a way to safely hit fast-twitch muscle in all age groups and whether McGuff has experience with EMS?
55:40: Doug discusses his experience with EMS and thinks it does let you hit the fast twitch fibers.
57:07: When you lose motor units, body starts to disconnect enervation of motor units.
57:52: Elderly with sarcopenia also have deconstructed this neuro-motor connection to higher-order motor units. “Where EMS is useful as a therapeutic modality is being able to activate type IIB motor units at the end of the set, so when they reach fatigue, that’s not fatigue like a younger person who still has that connection intact. You could invoke EMS at the end of the set to wake back up those type II motor units. The enervation of those motor units wakes up as well.” He says this is a “stop-gap measure to rehabilitate the enervation of higher-order motor units.
58:55: Commercial break: STEM-Talk is an educational service of the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging human cognition, perception, locomotion and resilience.
59:20: Ken mentions that Brian Caulfied at University College Dublin has been doing interesting and important work on EMS in both athletic populations and older cohort groups.
1:00:00: Ken says he’s optimistic about the future of EMS as new companies, such as PowerDot are offering systems that run on smart phones, etc.
1:00:39: Doug notes that people often “conflate athleticism and health.”
1:02:26: Ken notes that myokines have both local actions within the muscle tissue but also hormone like effects that target distant organs. He asks McGuff to discuss the role of myokines in exercise and the adaptations that occur as a result.
1:03:00: Resistance training is much greater than the sum of its parts.
1:04:30: Skeletal muscle is not just a tissue that produces movement. The muscle is the biggest and most active endocrine organ in our body; there’s a whole host of myokines—probably only of which a handful have been discovered. They are signaling locally and remotely—skin, hair, nervous tissue, cardiovascular system.
1:05:27: “The signals are going everywhere, and very few of them have been delineated thus far…. but the health benefits are becoming more and more obvious.”
1:05:46: The cytokines released by muscles have profound anti-inflammatory effects: they are the antithesis of metabolic syndrome and have anti-neoplastic effects. They are protective and reversive of neoplastic changes. “There’s a treasure trove there.”
1:06:30: Dawn asks about the role of myokines in tumor growth/suppression.
1:08:30: Doug says myokines have been found to arrest tumorigenesis for different types of cancer.
1:09:20: Different myokines are invoked by different forms and intensities of exercise.
1:10:35: Dawn asks how insulin sensitivity influences the production and sensitivity of myokines and Doug discusses their interaction.
1:12:11: Ken observed that recently the ketone body acetoacetate has been shown (in an animal model) to serve as a signaling metabolite in mediating muscle cell function and growth. Specifically, acetoacetate potentiated the stimulatory effect of IGF1 on muscle cell proliferation and antagonized the inhibitory effect of myostatin. Ken asks McGuff whether he sees a role for endogenous (or exogenous) ketone bodies in augmenting myokine-induced hypertrophy.
1:12:47: “The answer is yeah, I think so. It is just now becoming evident that those two operate by a similar mechanism.” Myostatin is a myokine that acts as a negative regulator of muscle growth.
1:14:00: With a sedentary lifestyle you can develop an overexpression of myostatin, one of the players in sarcopenia. It is upregulated in HIV, and certain cancer cells involved in cachexia.
1:14:18: “Acetoacetate has been shown to blunt its (myostatin) effect.”
1:15:10: Ketosis is when food supply is dwindling, and you tend to hunt and gather. The highest levels of physical output occur during hunting and gathering; it seems natural that ketosis and high level muscular activity would tend to occur/run in tandem. Those two things are running on parallel tracks biochemically.
1:16:17: Ken comments that both exercise induced myokines and ketone bodies appear to inhibit myostatin … yet pharma has spent decades looking for a safe and effective myostatin inhibitor.
1:17:00: McGuff refers to the Simon Melov paper which he found that 196 genes are expressed differently in youth and the elderly; they found an extensive reversal (back to their youthful levels) of gene expression in the elderly after physical training. Link to paper: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0000465
1:19:42: Dawn asks Doug about his thoughts on nutrition and to what extent does he see nutrition playing a role in skeletal muscle adaptation to exercise?
1:20:10: McGuff is a proponent of the Paleo diet: “You can never exercise your way out of a bad diet.”
1:22:28: Ken and Doug discuss how obesity is a recent phenomenon and that poor nutrition is at the heart of the problem.
1:28:08: Doug talks about his book, “The Primal Prescription: Surviving the Sick Care Sinkhole,” co-authored with economist Robert Murphy (http://amzn.to/2fLTBtl). It talks about the ER as the de facto safety net in the American healthcare system.
1:31:08: “[Writing the book] has given me a front-row seat to decay and collapse of medical system in this country; how it happened; and how recent attempts to address through ACA have put it on steroids, and made the medical system impossible to navigate.”
1:33:10: Dawn closes out the interview. She mentions McGuff’s lecture, entitled “Strength Training for Health and Longevity,” which can be viewed at: http://www.ihmc.us/lectures/20160929/.
1:34:20: Dawn and Ken sign off.
