Short Wave

The Dog Aging Project [https://dogagingproject.org/] is a long-term nationwide survey on the health and lifestyles of U.S. dogs that launched in 2019. Today, the project has more than 50,000 canines and counting. Today, hear what researchers have learned from one of the largest dog health data sets and what it could tell us both about increasing the lifespan of our furry friends and us.

"Olo" does not exist in nature, nor can it be found among paint cans. But for a very select few, olo can be seen — through the intervention of careful computing and lasers. A team led by vision scientist Austin Roorda [http://roorda.vision.berkeley.edu/] and computer scientist Ren Ng [https://www2.eecs.berkeley.edu/Faculty/Homepages/yirenng.html] at UC Berkeley figured out a method for stimulating only one specific subset of cones of the retina. It's the only way to view this spectacular teal. Creating the color is helping push the boundaries of vision science.

There are over 200 species of deep-sea anglerfish; some are long and thin, some are squat and round, some have fins that they use to "walk" along the sea floor, and others have huge eyes set far back into their heads. But how did all this morphological diversity first come to be? Thanks to a new anglerfish family tree, now we know. Scientists built this evolutionary tree using genetic information from hundreds of samples and anglerfish specimens across the globe. It indicates that anglerfish originated from an ancestor that crawled along the seafloor ... and sheds new light on how experts could think about biodiversity as a whole.

As artificial intelligence seeps into some realms of society, it rushes into others. One area it's making a big difference is protein science — as in the "building blocks of life," proteins! Producer Berly McCoy [https://www.npr.org/people/985775371/berly-mccoy] talks to host Emily Kwong [https://www.npr.org/people/767284140/emily-kwong] about the newest advance in protein science: AlphaFold3, an AI program from Google DeepMind. Plus, they talk about the wider field of AI protein science and why researchers hope it will solve a range of problems, from disease to the climate. Have other aspects of AI you want us to cover?

For hundreds of years sailors have told stories about miles of glowing ocean during moonless nights. This phenomenon is known as "milky seas," but the only scientific sample was collected in 1985. So atmospheric scientist Justin Hudson [https://graduateschool.colostate.edu/success-stories/justin-hudson/], a PhD candidate at Colorado State University [https://graduateschool.colostate.edu/success-stories/justin-hudson/], used accounts spanning 400 years to create a database of milky seas. By also using satellite images to visually confirm the tales, Justin hopes his research brings us one step closer to unraveling this maritime mystery.
