Another @sciam.bsky.social reader sent me this pic of them reading this memoir meets quantum physics by @kpc.bsky.social 🧪 Come hangout with me on June 1st for a nonfiction panel with Karmela and two other exciting nonfiction writers! @greenlightbklyn.bsky.social at 7:30pm ET 📚
When I heard the theory that the cruise ship hantavirus outbreak originated at a landfill in Argentina that is popular with birders, I had questions. I visited that dump on a bird-watching trip last year. It seemed like an unlikely infection site. So I did some digging. Here's what I found out 🧪 🪶

The hantavirus cruise outbreak may not have started in a garbage dump in Ushuaia, Argentina, after all

Did a bird-watching visit to this Argentine landfull spark the cruise ship hantavirus outbreak? Experts raise doubts
As @drkatemarvel.bsky.social explains here, when the US admin ended the NASA climate modeling group's office lease, they were kicked out of their building -- and "have been kind of couch surfing at various NYC universities and libraries" since then. Unbelievable. Read more here:

Happy Earth Day! 🌍 We've got several stories @sciam.bsky.social, including a look I took at where some blast-from-the-past environmental issues stand. (Hint: not all are in the past, though there has definitely been progress.) 🧪

The environmental crises of the past often seem to disappear—have problems like acid rain and smog been solved?

Whatever happened to the ozone hole, acid rain and DDT?
Fun bit of news: my @sciam.bsky.social Juno/Jupes feature, "A Planet Revealed", won the @aas.org 2026 Jonathan Eberhart Planetary Sciences Journalism award! Thanks aplenty to my glorious editor @clarakm.bsky.social for shaping it, and always letting me write big space-y tales. :)
