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 🧪 🪶

Pretty wild that we're still learning new things about chemistry and physics from the Trinity Test 🧪 www.scientificamerican.com/article/stra...

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 📚

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. :)

What does SpaceX's focus on AI mean for its exploration plans?

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.) 🧪

I'm feeling genuinely stoked about NASA's attempt to send humans on a trip back to the moon today. Go #Artemis! Keep up to date on the mission with us at @sciam.bsky.social www.scientificamerican.com/article/nasa...

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:

Just how massive can a star get? Pretty danged massive... but it depends on when you look. A thing I wrote for Scientiifc American, just like I do every Friday! www.scientificamerican.com/article/what... 🔭🧪

In our latest SciAm issue, Melinda Wenner Moyer explores a topic that is newly resonant with me: whether today’s kids are “all right”—socially, emotionally and mentally. www.scientificamerican.com/article/the-...

A new particle, woohoo! 🧪

I loved working on this fascinating story about galaxies that seem to defy our understanding of dark matter, part of the April issue out today www.scientificamerican.com/article/gala...

If you’re a worrier like me, it may surprise you to know that kids these days are doing better than previous generations in many ways. Join me to discuss the latest research during a live webinar this Thursday at 1pm ET, open to @sciam.bsky.social subscribers www.scientificamerican.com/page/events/

NEW: Sad news for those wanting the Moon to be hit by a sizeable asteroid: it ain’t happening, at least not in 2032. But at least we now that JWST is a surprisingly good asset for tracking dangerous space rocks! :) Me @sciam.bsky.social www.scientificamerican.com/article/noto...

In a "Jeffrey Epstein and the scientists" podcast w/ @iansample.bsky.social of The Guardian, we delve into the ugly world of Epstein and the scholars hurt by the misogyny in science that the files reveal: www.theguardian.com/science/audi...

Now on @sciam.bsky.social: The Schrödinger equation just turned 100, but that doesn’t mean quantum physicists have solved all its mysteries. Chief among them: What, exactly, does it mean to incorporate observers into the gnarly math? By Joseph Howlett. www.scientificamerican.com/article/the-...

NASA astronaut and ISS leader Mike Fincke transferred station command to a Russian cosmonaut ahead of an unprecedented medical evacuation

This is a first for NASA--hope the astronaut is ok!

The first full-fledged private space telescope could launch as early as 2029--here's a thoughtful look at what that might say about and mean for astronomical science: www.scientificamerican.com/article/schm... 🧪 🔭

This is such a cool finding--the oldest direct evidence of poisoned arrows. Poisoned hunting weapons were a game-changing innovation for our ancestors. Absolutely incredible that researchers found traces of plant toxins on these tiny arrowheads from 60,000 ago 🤯🏹 🧪

May I recommend this lovely long read, from one of my favorite writers on the planet, @annfinkbeiner.bsky.social, about the strange and surprising explosions astronomers are discovering in the night sky 🧪

Just a reminder that this year's Geminids meteor shower peaks tomorrow night! Do you have a plan to try to catch the spectacle?

Holy moly: The Nancy Grace Roman Space Telescope construction is completed! That's fantastic news — much needed right now — and I am very much looking forward to when this beast launches. It has 100X the field of view of Hubble. One. Hundred. *At the same resolution*. www.nasa.gov/image-articl...

Is ESA benefitting from increased international partnerships and funding due to countries/orgs looking to it rather than to a less stable/less well-funded NASA? "I think the answer is yes, in short." - David Phillips of @esa.int at #Appleton2025. Canada's ESA contribution is up 400% e.g. 🧪🔭

Wouldn't it be a ginormous waste to send a rover all the way to Mars to collect rock samples for study back on Earth and then to just...abandon them? By @astrojonny.bsky.social 🧪

Have you ever heard of Betty Webster? I hadn't until recently, and she co-discovered the first black hole ever found! Here's her story, to honor her memory and fantastic accomplishment. badastronomy.beehiiv.com/p/the-woman-... 🔭 🧪

True nightmare fuel: Scientists just confirmed the first known death from a severe meat allergy caused by a tick bite. The man, who died in 2024 after eating a burger, had alpha-gal syndrome, a bizarre disease triggered by tick bites. www.scientificamerican.com/article/man-...

I, for one, welcome our new trash panda overlords. But for real, fascinating science on how we might be seeing the very early stages of domestication in action in wild animals. 🧪 By @marinacoladas.bsky.social for @sciam.bsky.social

Lol the Nobels can't even acknowledge women's contribution to discovery. But sure let's acknowledge The Machines.

Now on @sciam.bsky.social: This year’s physics Nobel goes to 3 researchers who demonstrated quantum tunneling on a superconducting chip. By bringing this microscopic effect into the macroscale world, they laid important foundations for quantum computing. www.scientificamerican.com/article/2025...

This is a truly wild caper by @danvergano.bsky.social on the disappearance of the El Ali meteorite: www.scientificamerican.com/article/insi...

Some interesting sociology of space news to watch with the NYT dropping a fairly thin, but obvious piece by one of their anointed today www.nytimes.com/2025/09/20/u... saying the obvious: NASA's SpaceX lunar landing plans are unlikely to work anytime soon despite a lot of U.S. chest beating. 1/n

Ever wonder what happened to that $100 million interstellar spaceship program? Me too. www.scientificamerican.com/article/the-...

Great writeup by Sarah Scoles @sarahscoles.bsky.social on the apparent demise of Breakthrough Starshot

In 2016 billionaire Yuri Milner held a star-studded press conference where he pledged to spend $100 million to send the first spaceship to Alpha Centauri. But almost a decade later, Breakthrough Starshot doesn't have much to show for itself. What happened? @sarahscoles.bsky.social reports 🧪

Oh this is very cool #MathNerds
