    Much of the country is deep in the middle of a heat wave right now. And every summer, Duane Stilwell's town in Arizona seems to get hotter. It has him worried — and he's not the only one. Since 1980, the average number of heat waves in the U.S has doubled and the average length of a heat wave season has increased from 40 days to 70. Future summers, experts say, will be even hotter. But why exactly is that happening, and what can people do to protect themselves from the heat?This episode is part of Nature Quest, a monthly segment that answers listeners' questions about their local environment.

    The twilight zone of the ocean is a mysterious place. At 200-1000 meters below the surface, it's a tough place to study. That's why, during World War II, people reading sonograms from this zone were perplexed when it looked as if the ocean floor was moving up. Every day. And then back down again before dawn.

    Whether you love spiders or can't be within 10 feet of them, you probably think of them crawling around on land. Historically, most researchers would probably say the same thing: Based on the fossil record, they've thought the earliest arachnid ancestors existed around 450 million years ago, living and diversifying exclusively on land. But a new study out this week in the journal Current Biology suggests arachnid brains may have originated much earlier in the ocean. Want to hear more stories about the history of animals on Earth?

    Eating disorders are complicated illnesses that skyrocketed among teenagers during the COVID-19 pandemic. Pediatrician Eva Trujillo says they "literally rewire the brain," decrease brain size, and make it harder to concentrate and to regulate emotions. Malnutrition can slow the metabolism, impact bone density and even lead to cardiac arrest. But Eva says, with the right treatment, people can also recover fully. She's the president of the International Association of Eating Disorder Professionals and co-founder of Comenzar de Nuevo, a leading treatment facility in Latin America.

    Earlier this year, the White House proposed a nearly 24% cut to NASA's 2026 fiscal year budget — the largest in the agency's history. The trims are largely aimed at the NASA's fundamental science research and would halt science that has already been partially paid for, like the Mars sample return and the Nancy Grace Roman Space Telescope. Many scientists and policy experts are also worried that the reduced funding would cause a scientific brain drain. But within the last month, Congress has started to discuss appropriations packages that may not severely contract the budget after all.

    A warming climate doesn't just affect dry land — it affects the ocean, too. For years, Earth's ocean has acted as a heat sink for climate change: A large part of the heat generated by human use of fossil fuels is being absorbed by the ocean. And while the deep sea is largely unaffected by this heat absorption, oceanographers have discovered that the upper ocean currents are accelerating. That acceleration has the potential for huge knock-on effects, including sea level rise, changing fish migration cycles, shifting storm patterns, and more.This is the first episode of Sea Camp, Short Wave's summer series exploring the intriguing and otherworldly depths of the ocean.

    Since last week, Israel has been attacking Iran's nuclear facilities, along with many other targets around the country. Iran has fired hundreds of missiles in response. NPR correspondent Geoff Brumfiel has been watching all of this very closely because Israel's missile defenses have been a focus of the Trump White House. This year, President Trump requested funding from Congress for a "Golden Dome for America" — a missile defense system that would protect all of the United States. The idea comes from Israel's Iron Dome — a network of interceptor missiles stationed at points across the country. Iron Dome and related Israeli air defenses don't get every missile fired — including some launched in the past few days by Iran — but the Israeli military says it has intercepted thousands of rockets since it was built. Trying to get that kind of protection for America, though, might be a very different matter.

    "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 and computer scientist Ren Ng 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.Follow Short Wave on Spotify, and Apple Podcasts.More questions about the science behind our everyday lives?

    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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

    Solving A Centuries Old Maritime Mystery

    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, a PhD candidate at University of Colorado, 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.

    Why Daylight Boosts Immunity

    Depending on what time it is, your body responds differently to an injury or infection. During the day, you're likely to heal faster and fight infection better than at night. And historically, scientists weren't entirely sure why. That picture is starting to clear up thanks to a new study published last week in the journal Science Immunology. The research finds a missing piece of the puzzle in neutrophils, powerful immune cells that — despite living less than 24 hours — know the difference between day and night.Got a question about how the body works?

    It's Memorial Day, Short Wavers. This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend on them for GPS location, Internet timing, stock trading and even space navigation. In today's encore episode, hosts Emily Kwong and Regina G. Barber learn how to build a better clock. In order to do that, they ask: How do atomic clocks really work, anyway? What makes a clock precise? And how could that process be improved for even greater accuracy?- For more about Holly's Optical Atomic Strontium Ion Clock, check out the OASIC project on NASA's website.- For more about the Longitude Problem, check out Dava Sobel's book, Longitude.

    Riddle us this: Which animal is pink, curved beaked and a master of the physics required to create water tornadoes? If you guessed flamingos, you're right. New research out this month in the journal Proceedings of the National Academy of Sciences shows that across a range of harsh environments, flamingos have become masters — of physics, fluid dynamics and so much more — all in pursuit of their filter-fed prey. Short Wave host Regina G. Barber sits down with biomechanics researcher Victor Ortega Jiménez to hear all of the incredibly involved lengths these birds go through to get their prey.

    What's it like to get bit by a venomous snake? "It's like a bee sting times a thousand," Tim Friede says. Tim would know. Over the past few decades, he's let himself be bitten over 200 times by all kinds of venomous snakes — black mambas, taipans, cobras, kraits and more. With time, he's gradually built immunity to multiple types of venom. Could scientists help him share that immunity with others? Science reporter Ari Daniel joins Short Wave to explain how antivenom works, what scientists discovered and where the research may lead.
