Time heals all wounds
Did you know that some species of worms can be cut into multiple pieces and each piece will make a new worm? Some can even make a whole new brain. Wild, right?While not all forms of healing are quite as miraculous as this, the body’s ability to repair itself is pretty darned cool. So today, we’re answering your questions about healing. Like…Why do we pick at scabs?Why do animals lick their wounds?How does breath work affect the nervous system?What's the best outdoor activity to help heal from heartbreak?For our next Outside/Inbox roundup, we’re looking for questions all about love!

Of Men and Mice
At any given time, millions of lab mice are being used in research facilities nationwide. And yet nearly all of them can be connected back to a single source: The Jackson Laboratory in Bar Harbor, Maine, where the modern lab mouse was invented.What started as a research project aimed at understanding heredity is now a global business. Research on lab mice has led to more than two dozen Nobel prizes, helped save countless human lives, and has pushed science and medicine to new heights. But behind it all is a cost that’s rarely discussed outside of the ethics boards that determine how lab mice are used. In this episode, we hear the story of how a leading eugenicist turned the humble mouse from a household pest into science’s number one guinea pig. Plus, we get a rare peek inside the Jackson Laboratory - where over 10,000 strains of lab mice DNA are kept cryogenically frozen. Featuring Bethany Brookshire, Kristin Blanchette, Lon Cardon, Rachael Pelletier, Karen Rader, Nadia Rosenthal and Mark Wanner. Produced by Jeongyoon Han.

Time flies like an arrow. Fruit flies like a banana.
According to our unscientific office poll, the annual changing of the clocks has all the popularity of a root canal. With few exceptions, people described the shift to and from Daylight Saving Time as disorienting, arbitrary, and unwelcome.On a more existential level, winding the clocks back and forth reminds us that no matter how concrete minutes and hours may feel, the way we perceive time is fluid. Time flies when you’re having fun. A watched pot never boils. So to celebrate (or perhaps protest) another year setting back the clocks, the Outside/In team has uncovered four mini-stories that will poke at, stretch, or even obliterate your perception of time. From “time expansion experiences”, to time-space synaesthesia, to the slow-motion life of a fly, prepare for a totally different type of time warp.Featuring Steve Taylor, Rhitu Chatterjee, Kevin Healy, Katherine Akey, and Patricia Lynne Duffy.This episode was produced by Felix Poon.

Critical Mast
Every so often, oak trees go into overdrive. During these so-called mast years, the gentle patter of falling acorns grows into a mighty downpour and ripples across and over ecosystems like a flood. What happens when a small thing goes from scarce to plentiful? When a player usually hidden behind the scenes vaults onto the main stage? From swimming squirrels and bug-infested weddings, to an explosion in babies named Oaklee, we investigate the myriad ways a sudden surge in abundance can trigger unexpected consequences. This episode is part of a playful exercise in community podcasting, with 6 different shows each producing their own stories about or inspired by the mystery of masting, and releasing them at (approximately) the same time.

On the edge of the ice
Thwaites Glacier in Antarctica is massive, bigger than the state of Florida. If it collapses, it could reshape every coast on this planet during this century. That’s why it’s sometimes known as “the Doomsday Glacier.”And yet, until recently, we knew very little about it. Because Thwaites is extremely remote, reachable only by crossing the wildest ocean on the planet, scientists had never observed its calving edge firsthand. In 2019, a ground-breaking international mission set out to change that, and writer Elizabeth Rush was on board to document the voyage. We caught up with her to learn about life on an Antarctic icebreaker, how she grappled with classic Antarctic narratives about exploration (and domination), and how she summons hope even after coming face-to-face with Thwaites. This episode was first published in early 2024. Featuring Elizabeth Rush. SUPPORTOutside/In is made possible with listener support. Click here to become a sustaining member.

LINKSIf you’re interested in reading more about the journey to Thwaites, check out Elizabeth’s book, “The Quickening: Creation and Community at the Ends of the Earth”.A paper published in Nature with some of the findings from Elizabeth's voyage, showing that Thwaites has historically retreated two to three times faster than we’ve ever observed. Here’s the one detailing findings about Thwaites’ past extent, extrapolated from their study of ancient penguin bones, and another sharing observations about water currents beneath its ice shelf.The Trump administration has pulled funding for the US’s only Antarctic icebreaker dedicated to scientific research.
