As biologist M. Picard wrote in the June 2025 issue of Scientific American, “Mitochondria communicate, both within their own cells and among other cells, reaching out to support one another in times of need and generally helping the community flourish.” We’re proud to help @sciam.bsky.social thrive!

I somehow missed until recently that James S. A. Corey's latest scifi series had begun, even though we're nearly two books and a novella in. Don't make the same mistake I did! I chatted with the authors for @sciam.bsky.social and learned some cool stuff: www.scientificamerican.com/article/the-...

My feature is on the cover of @sciam.bsky.social !! This is one of the more fascinating, maddening, mind-boggling stories I've reported in a long time. Please come on this journey with me.

We assumed that chunks in Roman cement were the mark of poor mixing. Turns out they're the key to the self-healing properties that have made the cement so durable. 🧪 (By @humbertobasilio.bsky.social)

In 2015 a powerful new book about sudden changes to the moon and their far-reaching consequences for Earth and society as we know it hit the shelves—and science fiction author @scalzi.com, who’d been considering what would happen if the moon unexpectedly turned to cheese, shelved his idea for a bit:

If you need some holiday reading or gifting ideas, the @sciam.bsky.social staff read a bunch of books we really liked this year:

I'm here to tell you that my primary profession of being a shit poster is no more. I recently started (temporarily) hosting the Science Quickly podcast for @feltman.bsky.social while she's out on leave. Here is Rachel and I discussing the most important scientific subject on earth: Mayo

Heck, I'd take a two-bedroom at 1,080 square feet.

After decades of speculation, two writers uncovered the answer to the Kryptos code’s final cipher

Nice @sciam.bsky.social article by @sarahexplains.bsky.social on the NASA Exoplanet Archive reaching 6,000 planets! “You’re no longer just asking “what”; you’re asking “why”—“and that’s, for me, where it gets exciting.”

We've reached 6,000 confirmed exoplanets! I talked with @aussiastronomer.bsky.social about where things go from here. (A great graphic by @unamandita.bsky.social visualizes the amazing jumps in planet finds since the first ones were confirmed in the 1990s.)

A little bit of good news for you. And a reminder that we *can* solve big, global problems--when we want to. 🧪 (by @meghanbartels.bsky.social)

I had an enlightening conversation with mathematician Hannah Cairo about how she broke a huge conjecture in Harmonic Analysis at just 17 years old, what being a transgender mathematician means to her and how math has supported her along her journey! 🏳️‍⚧️ 🌊 ✨ Read the Q&A here:

Now on @sciam.bsky.social, from @philplait.bsky.social: The sky is falling—from another star. There's no "Chicken Little" nonsense here, though—this is legit: Some fraction of the meteors that streak thru Earth's skies are from beyond the solar system! www.scientificamerican.com/article/inte...

We finally made it to Bluesky—just a few billion years after the Big Bang, and only slightly late to the party ✨🌌 We’re sharing some of our best stories from the year so far to kick off our Bluesky journey!

I can't quite pinpoint why, but a certain book by @scalzi.com is going through my head as I contemplate this headline...

Vaccination schedules on the CDC website have already started changing under RFK Jr. So we published a guide to the evidence-based vaccine recommendations in place *before* all 17 members of the advisory panel were abruptly dismissed by the new admin. www.scientificamerican.com/article/see-... 🧪

Mathematicians are jittery after AI proves shockingly good at outsmarting them www.scientificamerican.com/article/insi...

Venus is alive! ... sort of. No aliens this time, just rocks. There are weird circle-y volcanic on Venus called coronae, and now scientists think that they're itty bitty baby circular subduction zones! How cool is that? 🧪🔭 Me for @sciam.bsky.social: www.scientificamerican.com/article/stra...

It's a cicada sex party! Wait, who invited the zombies? Periodical cicadas in Brood XIV are starting to appear, and so is the fungus Massospora cicadina, which infects and zombifies the cicadas. I wrote about what scientists hope to learn from Brood XIV cicada zombies, for @sciam.bsky.social 🧪

This caterpillar is metal as hell 🤘 🧪

“After 13 years of staring at the heads of twin and singleton babies, [Marjolaine Willems and her colleagues’] paper on the association between global hemisphere and _____ won the 2024 IgNobel prize in anatomy.” a. follicle density; b. scalp pointiness; c. hair whorl formation; d. bad hair days

www.scientificamerican.com/article/why-... "Congestion gets better for a little bit, and then we’re back to where we were. And then somebody says, ‘Oh, we’ve got to widen again.' ... So how far is it going to go?”

This is a really nice, simple distillation of the vital role NOAA and the NWS play and how private companies cannot replace what they do.
