What we can learn from a mass of black hole mergers, and ecological insights from 30 years of Arctic animal movements

First up, host Sarah Crespi talks with Staff Writer Adrian Cho about new gravitational wave detections from the first half of 2019—including 37 new black hole mergers. With so many mergers now recorded, astrophysicists can do different kinds of research into things like how new pairs of black holes come to be and how often they merge. Sarah also talks with Sarah Davidson, data curator at the Max Planck Institute of Animal Behavior, about results from an Arctic animal tracking project that includes 3 decades of location information on many species, from soaring golden eagles to baby caribou taking their first steps. The early results from the Arctic Animal Movement Archive show that researchers can use the database as a baseline for future Arctic investigations and to examine the effects of climate on ecosystems in this key region.

Taking the politicians out of tough policy decisions; the late, great works of Charles Turner; and the science of cooking

First up, host Sarah Crespi talks to News Intern Cathleen O’Grady about the growing use of citizens’ assemblies, or “minipublics,” to deliberate on tough policy questions like climate change and abortion. Can random groups of citizens do a better job forming policy than politicians? Next, we feature the latest of a new series of insight pieces that revisit landmark Science papers. Sarah talks with Hiruni Samadi Galpayage Dona, a Ph.D. student at Queen Mary University of London, about Charles Turner, a Black zoologist who published multiple times in Science in the early 1900s. Despite being far ahead of his time in his studies of animal cognition, Turner’s work was long overlooked—due in large part to the many difficulties facing a Black man in academia at the turn of the century. Finally, in our monthly books segment, host Kiki Sanford chats with author Pia Sorensen about her new book: Science and Cooking: Physics Meets Food, From Homemade to Haute Cuisine.

Early approval of a COVID-19 vaccine could cause ethical problems for other vax candidates, and ‘upcycling’ plastic bags

First up, host Sarah Crespi talks with Staff Writer Jon Cohen about some tricky ethical questions that may arise after the first coronavirus vaccine is authorized for use in the United States. Will people continue to participate in clinical trials of other vaccines? Will it still be OK to give participants placebo vaccines? Next, producer Meagan Cantwell talks with Bert Weckhuysen, a professor at Utrecht University, about a process for taking low-value plastic like polyethylene (often used for packaging and grocery bags) and “upcycling” it into biodegradable materials that can be used for new purposes.

Making sure American Indian COVID-19 cases are counted, and feeding a hungry heart

First up, host Meagan Cantwell speaks with Abigail Echo-Hawk, director of the Urban Indian Health Institute and chief research officer for the Seattle Indian Health Board. Echo-Hawk shares what inspired her journey in public health and explains the repercussions of excluding native people from health data. This story was originally reported by Lizzie Wade, who profiled Echo-Hawk as part of Science’s “voices of the pandemic” series. Next, host Sarah Crespi interviews Danielle Murashige, a Ph.D. student at the University of Pennsylvania, about her Science paper that attempts to quantify how much fuel a healthy heart needs.  This week’s episode was produced with help from Podigy.

Visiting a once-watery asteroid, and how buzzing the tongue can treat tinnitus

First up, Staff Writer Paul Voosen talks with host Sarah Crespi about the Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission to the asteroid Bennu. After OSIRIS-REx’s up-close surveys of the surface revealed fewer likely touchdown points than expected, its sampling mission has been rejiggered. Paul talks about the prospects for a safe sampling in mid-October and what we might learn when the craft returns to Earth in 2023. Sarah also talks with Hubert Lim, from the University of Minnesota, Twin Cities, and Neuromod Devices Limited, about his Science Translational Medicine paper on a new treatment for tinnitus. The team showed that bimodal stimulation—playing sounds in the ear and buzzes on the tongue—was able to change the brain and turn down the tinnitus in a large clinical trial. This week’s episode was produced with help from Podigy. Extra audio credits: Tinnitus sound samples courtesy of the American tinnitus Association. Treatment samples courtesy of Neuromod Ltd.

FDA clinical trial protection failures, and an AI that can beat curling’s top players

Investigative journalist Charles Piller joins host Sarah Crespi to discuss his latest Science exclusive: a deep dive into the Food and Drug Administration’s protection of human subjects in clinical trials. Based on months of data analysis and interviews, he uncovered long-term failures in safety enforcement in clinical trials and potential problems with trial data used to make decisions about drug and device approvals. Sarah also talks with Klaus-Robert Müller, a professor of machine learning at the Technical University of Berlin, about an artificial intelligence (AI) trained in the sport of curling—often described as a cross between bowling and chess. Although AI has succeeded in chess, Go, and poker, the constantly changing environment of curling is far harder for a nonhuman mind to adapt to. But AIs were the big winners in competitions with top human players, Müller and colleagues report this week in Science Robotics. This week’s episode was produced with help from Podigy.

How Neanderthals got human Y chromosomes, and the earliest human footprints in Arabia

Contributing Correspondent Ann Gibbons talks with host Sarah Crespi about a series of 120,000-year-old human footprints found alongside prints from animals like asses, elephants, and camels in a dried-up lake on the Arabian Peninsula. These are the earliest human footprints found so far in Arabia and may help researchers better understand the history of early hominin migrations out of Africa. Continuing on the history of humanity theme, Sarah talks with Janet Kelso of the Max Planck Institute for Evolutionary Anthropology, about her team’s efforts to fish the elusive Y chromosome out of Neanderthal and Denisovan DNA. It turns out Y chromosomes tell a different story about our past interbreeding with Neanderthals than previous tales told by the rest of the genome. Read a related Insight article.

Performing magic for animals, and why the pandemic is pushing people out of prisons

Staff Writer Kelly Servick joins host Sarah Crespi to discuss how jail and prison populations in the United States have dropped in the face of coronavirus and what kinds of scientific questions about public health and criminal justice are arising as a result. Also this week, Elias García-Pelegrín, a Ph.D. student at the University of Cambridge, talks with Sarah about his article on watching animals watch magic tricks. Do animals fall for the same illusions we do? What does it say about the way their minds work? This week’s episode was produced with help from Podigy. Listen to previous podcasts.

Alien hunters get a funding boost, and checking on the link between chromosome ‘caps’ and aging

First up this week, Senior Correspondent Daniel Clery talks with host Sarah Crespi about how Breakthrough Listen—a privately funded initiative that aims to spend $100 million over 10 years to find extraterrestrial intelligent life—has changed the hunt for alien intelligence-link.  And as part of a special issue on the Genotype-Tissue Expression  (GTEx) Project, Brandon Pierce, a professor in the Departments of Public Health Sciences and Human Genetics at the University of Chicago, joins Sarah to discuss his group’s work on variation in the protective caps at the end of our chromosomes. The gradual shortening of these caps, also known as telomeres, has been associated with aging.  Read more from the GTEx special issue. This week’s episode was produced with help from Podigy.
