    Hantavirus update, PCOS name change, ‘cheeky’ fish behavior
    May 18 2026
    In this episode of Science Quickly, we get the latest on the hantavirus outbreak with Tanya Lewis, Scientific American’s senior desk editor for health and medicine. We also unpack why the common health condition previously named polycystic ovary syndrome, or PCOS, is now called polyendocrine metabolic ovarian syndrome, or PMOS. Then SciAm’s chief newsletter editor Andrea Gawrylewski shares an interesting story about subatomic particles from this month’s issue of the magazine. And finally, we dive into the phenomenon known as “cloacal diving”—wherein one fish hides in another animal’s “butthole.” Recommended Reading: Can hantavirus spread through the air?

  • Why Black women face a silent health crisis

    Why Black women face a silent health crisis
    May 15 2026
    In this episode of Science Quickly, gynecologic oncologist and health equity researcher Kemi Doll explains why the well-known Black maternal mortality crisis is part of a broader “Black womb crisis” in which many Black women experience a lifetime of gynecologic health challenges. Drawing on research and personal stories from her new book A Terrible Strength, Doll explores how Black women face disparities in conditions such as fibroids, endometriosis, and endometrial cancer and how gaps in diagnosis, treatment and care contribute to worse outcomes for this population.

    Do you actually need more protein? What the science says
    May 13 2026
    Protein is having a major moment, showing up in everything from snack foods to coffee drinks—but do we actually need more of it? In this episode of Science Quickly, Rachel Feltman speaks with science journalist Bethany Brookshire about what has happened with the rise of the protein craze, how much protein people really need and why most of us are already getting plenty. They explore where the trend came from, what the science says about daily intake and how there are potential downsides to focusing too heavily on protein at the expense of overall diet and sustainability.

  • Hantavirus at sea, microplastics, and the Alaska tsunami mystery

    Hantavirus at sea, microplastics, and the Alaska tsunami mystery
    May 11 2026
    In this science news roundup, we start with a deadly hantavirus outbreak linked to a cruise ship. The outbreak is raising concerns about rare human‑to‑human transmission while experts say the risk of a wider pandemic remains low. We also look at new research showing that airborne microplastics and nanoplastics may be contributing to global warming—an unexpected climate effect of plastic pollution. And in Alaska, a massive retreating-glacier‑driven landslide that triggered a dramatic tsunami offers new clues that could help improve early-warning systems in the future.

    Influencers are obsessed with peptides. What does the science say?
    May 8 2026
    Peptides are everywhere right now—from weight-loss drugs to TikTok wellness hacks—but the science hasn’t caught up with the hype. Journalist Victoria Song joins Science Quickly host Rachel Feltman to break down what peptides actually are, why influencers are promoting “research-only” versions you can buy and inject yourself, and what risks are posed by this growing gray-market trend. From misleading marketing to real safety concerns, we unpack the Internet’s latest wellness obsession. Recommended Reading: “Influencers are pushing suspicious peptides. How much are you willing to risk?” by Victoria Song in the Verge. Published online January 23, 2026 “I don’t think Gwyneth Paltrow knows what a peptide is,” by Victoria Song in the Verge.
