  • These Adorable Hamster Dads Take Fatherhood Seriously

    Most mammalian dads are pretty absent from their offspring’s lives. That sets the Djungarian hamster apart from its fellow fathers. These hamster dads are involved in the birth of their pups, care for them in infancy and even provide food during weaning. They also let the mother hamster go on cooldown walks outside of the burrow, which professor of veterinary medicine and hamster expert Katherine Wynne-Edwards thinks could be essential to the survival of the species in its superharsh environment. But there’s also some familiar mate selection at play: female Djungarian hamsters choose to mate with males who will provide quality parental care.

  • What ‘Immortal’ Jellyfish and Famously Old Tortoises Tell Us about Aging

    Animals’ lifespans can be far shorter or much longer than those of humans. Scientists are researching creatures such as “immortal” jellyfish and long-lived tortoises and digging deep into genetic codes to figure out why animals age—and what we can do to improve longevity in humans. João Pedro de Magalhães, chair of molecular biogerontology at the University of Birmingham in England, lays out the state of aging science.

  • Cosmic Coin Toss, Record Heat in the North Atlantic and Living Worm Towers

    New simulations suggest the Milky Way’s long-predicted collision with Andromeda might be less of a cosmic certainty than we thought. A massive marine heat wave in 2023 sent North Atlantic temperatures soaring—equal to two decades’ worth of typical warming—with weak winds and climate change largely to blame. And researchers reveal that the planet’s most abundant animals—nematodes—may use teamwork and tower-building to hitch rides to new homes.

  • Is the National Weather Service Ready for an Extreme Summer?

    The dedicated staff of the National Weather Service are responsible for the data that underpin your weather forecast and emergency alerts. DOGE Service cuts to the NWS are putting the collection and communication of those data at risk right as we enter a dangerous season of hurricanes, tornadoes, wildfires and extreme heat in the U.S. Senior sustainability editor Andrea Thompson joins host Rachel Feltman to explain what the NWS does, why we need its expertise and what we risk when that expertise is lost.

  • Megalodon Diets, Teeth Sensitivity and a Bunch of Vaccine News

    The measles outbreak in West Texas is slowing. Health officials think an increase in vaccination rates contributed to the slowdown, but Texas lawmakers have pushed a new bill to make it even quicker and easier for parents to exempt their children from vaccines. The Centers for Disease Control and Prevention goes counter to the American College of Obstetricians and Gynecologists by removing recommendations for COVID vaccines for pregnant people and children without underlying health conditions. The first vaccine for gonorrhea debuts in England and Wales, with early results suggesting it is 30 to 40 percent effective against the disease. Your sensitive teeth may have origins in the dentin in the exoskeletons of ancient fish. Plus, researchers use fossils to discover what megalodons may have eaten.

  • Are You Flourishing? This Global Study Has Surprising Takeaways

    Are you flourishing? It’s a more understated metric than happiness, but it can provide a multidimensional assessment of our quality of life. Victor Counted, an associate professor of psychology at Regent University and a member of the Human Flourishing Program at Harvard University, joins host Rachel Feltman to review the first wave of results from the five-year, 22-country Global Flourishing Study. Counted reflects on the difficulty of applying a universal concept to varied cultural contexts and ways that we can control our own flourishing.

  • Diagnosing Male Infertility with a Mechanical Engineering Twist

    Male infertility is undercovered and underdiscussed. If a couple is struggling to conceive, there’s a 50–50 chance that sperm health is a contributing factor. Diagnosing male infertility is getting easier with at-home tests—and a new study suggests a method for testing at home that would be more accurate. Study co-author Sushanta Mitra, a professor of mechanical and mechatronics engineering at the University of Waterloo in Ontario, joins host Rachel Feltman to discuss how lower sperm adhesion could be used as a proxy for higher sperm motility.

  • Could We Speak to Dolphins? A Promising LLM Makes That a Possibility

    Dolphins have a broad vocabulary. They vocalize with whistles, clicks and “burst pulses.”This varied communication makes it challenging for scientists to decode dolphin speech. Artificial intelligence can help researchers process audio and find the slight patterns that human ears may not be able to identify. Reporter Melissa Hobson took a look at DolphinGemma, a large language model created by Google in collaboration with the Wild Dolphin Project and the Georgia Institute of Technology. The project seeks to unravel the clicks from the whistles and to understand what dolphins chat about under the waves.

    Mitochondria are known as the powerhouse of the cell—but new research suggests they might be far more complex. Columbia University’s Martin Picard joins Scientific American’s Rachel Feltman to explore how these tiny organelles could be communicating and what that might mean for everything from metabolism to mental health.
