Update: The crew splashed down off the coast of San Diego, Calif., around 8:07 P.M. EDT: www.scientificamerican.com/article/nasa...

Hi! Yes, the timeline is in EDT. Good q!

Timeline shows the progression of the Orion capsule’s 400,000-foot descent from when it enters Earth’s atmosphere at 7:53 P.M. to its scheduled splashdown at 8:07 P.M.

It's happening—we're about 2 hours away from the Artemis II mission splashdown! Here's a timeline of what to expect.

Those of us at @sciam.bsky.social glued to the Artemis II livestream all day had some questions about the crew’s taste in music.

We finally got some answers: www.scientificamerican.com/article/what...

Earthrise, 2026

“There’s the Earth comin’ up,” Anders said at the time. “Wow, is that pretty!” Anders later compared the sight of the Earth to “a fragile Christmas tree ornament.” “I thought to myself, it's too bad we don't treat it more like a Christmas tree ornament,” Anders said in a 2023 NASA interview. “It's really too bad, we're shooting missiles and rockets and whatnot at each other on this tiny little place we call home,” Anders added. “It's the only home in the universe for us humans. And it's too bad we don't treat it a little better.”

Astronaut Bill Anders took the iconic 1968 photo "Earthrise."

“It's really too bad, we're shooting missiles and rockets and whatnot at each other…" Anders later said. "It's the only home in the universe for us humans."

What are the best foods for a hangover, scientifically? There’s no bulletproof remedy for a hangover, but a nutrition scientist explains which foods could aid symptoms after one has had too much to drink

How to win The Traitors, according to science Experts say that to win a game like The Traitors, competitors should look for verbal clues over physical ones—and be friendly and open

Ahead of The Traitors finale tonight (!!) I spoke with some experts about the science of lie detection. Some fun things I learned:

-most people are terrible at detecting lies
-verbal clues > physical ones
-beware of the hot traitor "halo effect"

The physics of ‘Penisgate’ and how ski jumpers fly A scandal involving allegedly enlarged ski suits ahead of this year’s Winter Olympics has highlighted the intriguing physics behind ski jumps

How does adding extra room in the crotch area of a ski jumper’s suit actually change their jumping distance?

I spoke to some experts about the physics of 'Penisgate' and had too much fun writing this: www.scientificamerican.com/article/the-...

FDA won’t consider a new mRNA vaccine for flu despite the technology’s life-saving promise The U.S.’s drug safety agency declined to review a next-gen flu vaccine that uses the same tech as the coronavirus shots

FDA is refusing to consider Moderna's mRNA flu vaccine. Yet, as @angierasmussen.bsky.social explains, if we had mRNA vax technology for flu, we might have been able to quickly update this season's shots to cover subclade K before it hit the US. @jackiefmogensen.bsky.social reports @sciam.bsky.social

The Schrödinger equation is getting a glow-up for its 100th birthday A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking what happens when the observer is part of that world

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.

Mystery tower fossils may be a whole new kind of life Towering prototaxites ruled Earth before trees—and they may have been a form of life entirely new to science

The, er, thing below is called a Prototaxite. Turns out it may be a new branch of life. That is extremely cool and I have absolutely no idea why you are laughing... 🧪

U.S. Axes Number of Recommended Childhood Vaccines in Blow to Public Health The U.S. Centers for Disease Control and Prevention is reducing the recommended number of vaccines to protect against 11 diseases, instead of the 17 it recommended previously

Trump's CDC has officially changed the U.S. vaccine schedule, slashing the number of recommended shots in a move experts say will blow up decades of success with childhood vaccines. By @jackiefmogensen.bsky.social for @sciam.bsky.social www.scientificamerican.com/article/u-s-...

Why do we trust ChatGPT? The science of how AI chatbots captivate, entertain, and influence us

Have you ever shared something personal—a secret, a worry, a problem—with ChatGPT? Asked an AI chatbot for advice? Just a few years ago, for many, that might've been an odd thing to do.

I spoke with scientists about what's changed: www.motherjones.com/politics/202...

“The administration’s explicit goal to unleash the fossil fuel industry will also unleash plastic pollution.”
