Short Wave

Dogs are man’s best friend. And it’s no secret that we at Short Wave love cats (Regina has four)! Both of these iconic pets have been domesticated – evolved and adapted to live alongside humans – for millennia. And a recent study suggests that the common raccoon may be on its first steps towards joining them. So how do scientists look for signs of domestication and what do those signs mean? And could you have a litter box trained raccoon in your lifetime? We talk to the study’s lead author, Raffaela Lesch, to find out.Interested in more animal science stories?

And insurance coverage has been tricky to navigate for a lot of people. That’s why there’s a lot of excitement around a new pill form of the drug. NPR Pharmaceuticals Correspondent Sydney Lupkin chats about these experimental pills with host Emily Kwong. Check out more of NPR’s coverage about GLP-1s.Interested in more health stories?

Humankind has the technology to go to space. Space architect Ariel Ekblaw says the bottleneck now is real estate: getting larger volumes of space stations in orbit. Her company is working on the equivalent of giant, magnetic space Legos—hexagons that could self-assemble in space into livable, workable structures. This episode, host Regina G. Barber talks to her about this space architecture and why she says that the goal isn’t to abandon Earth–but to off-world industries like agriculture and manufacturing in order to build a better Earth.If you liked this episode, check out our Space Camp series.Interested in more space tech episodes?
