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...

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 🧪

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 🧪

Which hypothetical quasiparticle would you most like to see proven to be real? Many would vote for the axion (named after a detergent because it cleans up a mess in quantum chromodynamics), but for purely etymological reasons, I'm now voting for the neglecton. 🧪⚛️ physicsworld.com/a/predicted-...
