    Hantavirus at sea, microplastics, and the Alaska tsunami mystery

    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?

    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.

    NASA Curiosity, suicide hotline hope, AI voice clone

    In this week’s Science Quickly news roundup, we dive into NASA’s new discovery of organic molecules on Mars, including some that have never been found there before. We also explore how human migration may have been shaped by a surprising factor: malaria. Plus, we go over the encouraging results of a new study that links declines in youth suicides in the U.S. to the adoption of the three-digit 988 Suicide & Crisis Lifeline in 2022. And finally, we’ll turn to some interesting findings about AI voice clones.
