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…

1. Why do we pick at scabs?
2. Why do animals lick their wounds?
3. How does breath work affect the nervous system?
4. 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! From what happens in our bodies when we fall in and out of love, to whether animals fall in love. Send us your questions by recording yourself on a voice memo, and emailing that to us at outsidein@nhpr.org. Or you can call our hotline: 844-GO-OTTER.

Featuring Mansi Srivastava, Mona Gohara, Susan Taylor, Henk Brand, Jane Sykes, Aditi Garg, Carolina Estêvão, and Sandra Langeslag.

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. For a transcript and full list of credits, go to outsideinradio.org.

The garment industry has a giant carbon footprint, labor issues, and a massive waste problem. We have the power to change how and where we shop, but there’s another way to shift our consumption: the practice of repairing our clothes. After all, the most sustainable garment is always the one already hanging in your closet.

But mending is more than a household chore: it can also infuse new joy in our habits, skills, perspective, and community.

Outside/In producer Justine Paradis talked to a few repair pros and came up with 8 tips on embracing a repair mindset, lengthening the life of our clothes, and getting the practice of mending into the rhythm of our lives.

Featuring Emilia Petrarca, Dante Zagros Gonzalez, Steve Foss, Arounna Khounnoraj, Sonali Diddi, Vrylena Olney, Ely Spencer, and Ali Mann.

A few extraordinary examples of mending: Celia Pym’s Norwegian Sweater, a Japanese fisherman’s jacket constructed with sashiko, wool coats repaired with lavish embroidery, and a plain white t-shirt mended by Maya Skylark.

Look for mending classes at your local library, thrift stores, knitting shops, or other community gathering places. Remote classes are also offered at places like Tatter. You can also find a repair cafe near you, explore starting your own, or try throwing a repair party with friends.
