• An Apple Is An Ovary: The Science of Apple Breeding

  What's your favorite apple? Maybe it's the crowd-pleasing Honeycrisp, the tart Granny Smith or the infamous Red Delicious. Either way, before that apple made it to your local grocery store or orchard it had to be invented — by a scientist. So today, we're going straight to the source: Talking to an apple breeder. Producer Hannah Chinn reports how apples are selected, bred, grown ... and the discoveries that could change that process. Plus, what's a "spitter"?Read more of Hannah's apple reporting.Want to know how science impacts other food you eat?

• Mental ‘Workouts’ Could Keep Your Brain Young

  Scientists have found the first compelling evidence that cognitive training can boost levels of a brain chemical that typically declines as people age. The results of this 10-week study back earlier animal research showing that environments that stimulate the brain can increase levels of certain neurotransmitters. And other studies of people have suggested that cognitive training can improve thinking and memory. So how does it all work? And by how much does it all work? Here to break everything down and help you understand how to keep your brain sharp is NPR science correspondent Jon Hamilton.Interested in more brain science?

• Are we cooked? How social media shapes your language w/ Adam Aleksic (from TED Tech)

  This week, we’re sharing a special episode from TED Tech exploring Gen Z slang words like "unalive," "skibidi" and "rizz." Where do these words come from — and how do they get popular so fast? Linguist Adam Aleksic explores how the forces of social media algorithms are reshaping the way people talk and view their very own identities. Technology’s role in our lives is evolving fast. TED Tech helps you explore the riveting questions and tough challenges we’re faced with that sit at the intersection of technology and humanity. Listen in every Friday, with host, journalist Sherrell Dorsey, as TED speakers explore the way tech shapes how we think about society, science, design, business, and more. Listen to TED Tech wherever you get your podcasts or go to: https://link.mgln.ai/Ng9EKL Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

• Data Centers, Icy Moons And Chameleons

  It’s another news roundup! This time, we cover how, using data analytics – and ironically, some AI – a team at Cornell University has mapped the environmental impact of AI by state. They determined that, by 2030, the rate of AI growth in the U.S. would put an additional 24 to 44 million metric tons of carbon dioxide into the atmosphere. The team further calculated that by 2030, AI could use as much water as 6 to 10 millions Americans do every year. All of this, they conclude, would put the tech industry’s climate goals out of reach. This episode, we also get into the potential for life on one of Saturn’s moons and a new discovery about why chameleons’ eyes are so special. Interested in reporting on the environmental impact of AI?

• The Future Of Immune Health Might Be Here

  David Ewing Duncan has spent the last 25 years being poked and prodded in the name of science. He’s signed up for hundreds of tests because, as a journalist, he writes about emerging health breakthroughs. He says one recent test contains more useful data than anything he’s seen to date. He talks to host Emily Kwong about his score on the Immune Health Metric, which was developed by immunologist John Tsang. Together, David and John explain why immune health is so central to overall health and how a simple blood test could one day predict disease before it starts.Learn more about the Human Immunome Project.Read David’s full article about his experience with the Immune Health Metric. The piece is a collaboration between MIT Technology Review and Aventine, a non-profit research foundation that creates and supports content about how technology and science are changing the way we live.
