    Megalodon Diets, Teeth Sensitivity and a Bunch of Vaccine News
    2025/06/02
    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? This Global Study Has Surprising Takeaways
    2025/05/30
    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

    Diagnosing Male Infertility with a Mechanical Engineering Twist
    2025/05/28
    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

    Could We Speak to Dolphins? A Promising LLM Makes That a Possibility
    2025/05/23
    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.

  • Could Freezing Arctic Sea Ice Combat Climate Change?

    Could Freezing Arctic Sea Ice Combat Climate Change?
    2025/05/16
    The year-round sea ice in the Arctic is melting and has shrunk by nearly 40 percent over the past four decades. Geoengineering companies such as Real Ice are betting big on refreezing it. That may sound ridiculous, impractical or risky—but proponents say we have to try. The U.K. government seems to agree, investing millions into experimental approaches such as Real Ice’s. Pulitzer Center Ocean Reporting Fellow Alec Luhn is taking us with him to the Arctic to see what it takes to freeze sea ice in the already freezing cold.

  • How a West Texas Outbreak Threatens Measles Elimination Status

    How a West Texas Outbreak Threatens Measles Elimination Status
    2025/05/14
    Measles was technically “eliminated” in the U.S. in 2000 thanks to high measles, mumps and rubella (MMR) vaccination rates. While prior outbreaks have made headlines, a slew of cases in West Texas is more than just newsworthy—it could cause the U.S. to lose elimination status. Associate health and medicine editor Lauren Young explains what elimination means, why measles cases are rising and how to prevent further transmission.
