   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. Recommended Reading:…
