Science, Spoken

During a recent Uber ride, Madhuri Hegde’s driver asked her what she did for a living. The chief scientific officer for laboratory services at PerkinElmer, she prepared to bore him with a description of the tests her company had developed—most recently to flag serious genetic disorders. Instead, he was intrigued. “Where can I get one of those?” he asked. For years, PerkinElmer has only offered that clinical test to doctors. Learn about your ad choices: dovetail.prx.org/ad-choices

A few rules for the cleanroom where NASA’s new InSight Mars lander waits for launch. One, if you must sneeze, sneeze away from the spacecraft. Two, if you drop anything, let one of NASA’s escorts pick it up for you. Three, do not under any circumstances cross the black-and-yellow-striped tape and touch the spacecraft. Oh also—an engineer tells a dozen media in a conference room at Vandenberg Air Force Base—do not lick the spacecraft. Learn about your ad choices: dovetail.prx.org/ad-choices

Rock-Paper-Scissors works great for deciding who has to take out the garbage. But have you ever noticed what happens when, instead of playing best of three, you just let the game continue round after round? At first, you play a pattern that gives you the upper hand, but then your opponent quickly catches on and turns things in her favor. As strategies evolve, a point is reached where neither side seems to be able to improve any further. Learn about your ad choices: dovetail.prx.org/ad-choices

Around 2013, plastic surgeons like Boris Paskhover started to notice a bizarre trend in their doctor’s offices. More and more young patients—under 40, as young as 20—were asking for nose jobs. In Paskhover’s office in New York, new patients would plop down, hand over their phone, and complain about how their schnoz looked in selfies. In turn, Paskhover would hand them a mirror and tell them to take a look. “This is what you really look like,” he says. Learn about your ad choices: dovetail.prx.org/ad-choices

Getting older is supposed to give you perspective. But for one out of five people over the age of 65, it does the opposite. Macular degeneration is a common progressive eye condition, one that thins and breaks down a tissue behind the center of the retina. Without that tissue, the light-sensing cells it supports atrophy and die, making it impossible to get a clear picture of anything straight ahead of you—like, say, the faces of your loved ones or anything past your steering wheel.

It's tough being a parent. Sometimes I try to help my kids with their physics homework because I like to pretend that I'm sort of OK with physics. Recently, my daughter wanted me to check her answer for this question. Where do you weigh more, at the equator or at the North Pole? Oh boy. I'm not sure what answer to give. OK, I think I know the answer and I also think I know the answer that the teacher wants (and these two answers might not be the same). Really, it's not the best question.

Step one: Gently suck up the bumblebees with a special vacuum. Step two: Place them in the fridge to chill until they’re immobilized. Step three: Remove bees and superglue a sort of tiny, simplified QR code on their backs. Superglue what, you say? Yes, QR codes—a pretty significant upgrade for entomologists. Researchers used to stand over colonies, laboriously tracking the behavior of individual bees. Learn about your ad choices: dovetail.prx.org/ad-choices

Scientists, environmentalists, and anyone who lives within a hundred miles of the winding Mississippi River will tell you—have told you, repeatedly, for 150 years—that efforts to tame the river have only made it more feral. But scientists would like more than intuition, more than a history of 18th-century river level gauges and discharge stations, more than written and folkloric memory. They would like proof. Luckily, rivers inscribe their history onto the landscape. Learn about your ad choices: dovetail.prx.org/ad-choices

In 1965, physicist Richard Feynman was busy. He was busy winning the Nobel Prize, and he was busy learning to draw. One day during that productive time in his life, he saw astrophysics student Virginia Trimble striding across Caltech's campus and thought, There's a good model. Soon, she was posing for him a couple Tuesdays a month, in exchange for $5.50 each session and a lot of physics talk. Learn about your ad choices: dovetail.prx.org/ad-choices

Biotech has been betting big on Crispr, the gene-editing technique that promises to snip away some of humanity’s worst diseases. But last May, a small case study suggested the much-hyped technology might actually be quite dangerous—and pop went the Crispr bubble, briefly tanking shares of Crispr companies like Editas Medicine, Intellia Therapeutics, and Crispr Therapeutics.
