Learn a new language faster than ever! Leave doubt in the dust! Be a better sniper! Could you do all that and more with just a zap to the noggin? Maybe.

Back in the early 2010s, Sally Adee, then an editor at New Scientist Magazine, went to a DARPA (Defense Advanced Research Projects Agency) conference and heard about a way to speed up learning with something called trans-cranial direct current stimulation (tDCS). A couple of years later, Sally found herself wielding an M4 assault rifle to pick off simulated enemy combatants with a battery wired to her temple. But that got then-producer Soren Wheeler thinking about this burgeoning world of electroceuticals, and if real, what limits will it reach.

For this episode, first aired back in 2014, we brought in Michael Weisend, then a neuroscientist at Wright State Research Institute, to tell us how it works (Bonus: you get to hear Jad get his brain zapped). And sat down with Peter Reiner and Nick Fitz, then at the University of British Columbia, to help us think through the consequences of a world where anyone with 20 dollars and access to a circuit board and a soldering iron, can make their own brain zapper. And then checked-in again to hear about the unexpected after-effects a day of super-charged sniper training can have on one mild-mannered science journalist.

This episode, originally aired more than a decade ago, attempts to answer one question: how do you win against your worst impulses? Zelda Gamson tried for decades to stop smoking, but the part of her that wanted to quit couldn’t beat the part of her that refused to let go. Adam Davidson, a co-founder of the NPR podcast Planet Money, talked to one of the greatest negotiators of all time, Nobel Prize-winning Economist Thomas Schelling, whose tactical skills saw him through high-stakes conflicts during the Cold War but fell apart when he tried them on himself in his battle to quit smoking. And a baby Pat Walters complicates things — in a good way — with the story of two brothers, Dennis and Kai Woo, who forged a deal with each other that wound up determining both of their futures.

Killer whales — orcas — eat all sorts of animals, including humpback calves. But one day, biologists saw a group of humpback whales trying to stop some killer whales from eating… a seal. And then it happened again. And again. It turns out, all across the oceans, humpback whales are swimming around stopping killer whales from hunting all kinds of animals — from seals to gray whales to sunfish. And of course while many scientists explain this behavior as the result of blind instincts that are ultimately selfish, much of the world celebrates humpbacks as superhero vigilantes of the sea. But when Annie McEwen dug into what was really going on between humpbacks and killer whales, she found a set of stories that refused to fit in either of those two ways of seeing the world.Special thanks to Eric J.

This episode originally aired in 2012.

An all-star lineup of producers — Pat Walters, Lynn Levy, and Sean Cole — bring you stories about traps, getaways, perpetual cycles, and staggering breakthroughs.

We kick things off with a true escape artist — a man who’s broken out of jail more times than anyone alive. Why does he keep running... and will he ever stop? Next, the ingeniously simple question that led Isaac Newton to an enormous intellectual breakthrough: why doesn’t the moon fall out of the sky? In the wake of Newton's new idea, we find ourselves in a strange space at the edge of the solar system, about to cross a boundary beyond which we know nothing. Finally, we hear the story of a blind kid who freed himself from an unhappy childhood by climbing into the telephone system, and bending it to his will.

Now sit back, relax and enjoy what we hope will prove to be a welcomed Escape.Episode Credits:Reported and produced by Pat Walters, Lynn Levy, and Sean Cole

This week, Reporter Peter Smith and Senior Producer Matt Kielty tell the story of the U.S. Supreme Court decision that set the standard for scientific expertise in a courtroom, i.e., whether an expert can testify in a lawsuit. They also tell the story of the Daubert family — yes, the Dauberts of “Daubert v Merrell Dow” — whose win before the nine justices translated into a deeper loss.

Special thanks to Leah Litman, Rachel Rebouche, Jennifer Mnookin, David Savitz, Brooke Borel, and Tom Zeller Jr.

This is an episode that first aired in 2018 and then again in the thick of the pandemic in 2020. Why? Because though Horseshoe crabs are not much to look at, beneath their unassuming catcher’s-mitt shell, they harbor a half-billion-year-old secret: a superpower that helped them outlive the dinosaurs, survive all the Earth’s mass extinctions, and was essential in the development of the COVID vaccines. And what is that secret superpower? Their blood. Their baby blue blood. And it’s so miraculous that for decades, it hasn’t just been saving their butts, it’s been saving ours too.

But that all might be about to change.

Follow us as we follow these ancient critters - from a raunchy beach orgy to a marine blood drive to the most secluded waterslide - and learn a thing or two from them about how much we depend on nature and how much it depends on us.

Today, we go to a spot that may be one of the most philosophical places in the universe: the thymus, an organ that knows what is you, and what is not you. Its mood may be existential, but its role is practical — the thymus is the biological training ground where the body learns to protect itself from outside invaders (think: bacteria, coronaviruses). But this training is not the humdrum bit of science you might expect. It’s a magical shadowland with dire consequences.

Then, we’ll leave the thymus to visit a team of doctors who are using this organ that protects you as a way to protect someone… else. Their work could change everything.

Special Thanks:

One thousand thanks to Hannah Meyer, Salomé Carcy, Josh Torres, and Cold Spring Harbor Laboratory for showing us a real-life (mouse) thymus for this episode. Special thanks also go to Diane Mathis and Kate Webb.
