No, I don't want AI to summarize my long documents, it is literally my job to be able to read long documents and formulate opinions about them, can I not just open a .pdf in peace anymore

UNTIL IT’S DONE, Ep. 4: Sylvia Rivera

In the 1970s, queer New Yorkers had been pushed to the margins of NYC. Our trans neighbors faced immense cruelty. But in Sylvia Rivera, they found a champion.

As we combat Trump’s politics of darkness, her legacy can light the path forward.

How can we tell what's inside an #exoplanet? @timlichtenberg.bsky.social et al review how a planet's atmosphere interacts with its interior. Atmospheric observations can distinguish between lava worlds, water worlds, temperate surfaces or supercritical interiors. ☄️

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

A Rutgers professor has been forced to flee the country for his safety, after targeting by a far-right student group that was *checks notes* claiming they felt unsafe.

I'm horrified.
I'm angry.

Getting off social in the sense of burrowing a few feet below the surface, exuding a mucus cocoon, and waiting for fairer conditions to return.

I visited the apartment building ICE raided on Tuesday today. Story to come, but you can walk right in. Half of the apartments have no doors on them. Children's stuff abandoned in some flats. *Citizen* residents told me they were arrested and held for hours in zipties. This is America

A study suggests AI could help evade controls on synthesising bioweapons. Here's why this is like doing a fancy Mission Impossible-style bank raid when the vault door has been left open, the alarm is off and the guards are asleep 🧪

Should we worry AI will create deadly bioweapons? Not yet, but one day
AI tools are being used to design proteins and even viruses, leading to fears these could eventually be used to evade bioweapon controls

Yesterday’s #OTD *should* have been astrophysicist Dr. George Carruthers, born 1939. He developed a UV spectrograph (launched in 1970 on a sounding rocket) that confirmed the existence of interstellar hydrogen, and a similar device placed on the moon by Apollo 16. 🧪 ⚛️

I’m reading an advance copy of a new pop science quantum book and in the first 100 pages it’s already twice claimed that quantum computers will solve climate change. If I weren’t reading for work, I’d rage quit right about now. We (science writers) gotta do better!

The possibility of a shutdown has become routine in recent years (near misses in December and March). Now, the government has actually shut down, and the administration has threatened to use the opportunity for massive permanent layoffs.

Our story on the potential impacts for science:
This US government shutdown is different: what it means for science
President Trump’s budget office lays out guidelines for mass lay-offs across the federal government.

I've become such a grinch lol. As soon as I saw this, my "ITS NOT A BIOSIGNATURE" hackles went straight up 😅😂

This looks genuinely interesting, though. If it is a sign that there's active hydrothermalism on Enceladus then the lil snowball would be an even more exciting target for alien hunting.

🆕 The discovery of new complex organic molecules at Saturn's #Enceladus enhances the likelihood that the moon is habitable 🪐

On Earth, these molecules are involved in chemical reaction chains that lead to the more complex molecules essential for life.

Scientific illustration showing a cross-section of Saturn’s moon Enceladus. It features three labelled layers: An ice shell at the top, with visible cracks releasing jets of water vapour into space; an ocean in the middle, depicted as a large body of water beneath the ice; a rocky core at the bottom, shown emitting heat that may drive the jets. In the background, Saturn and its rings are visible in space.

Ohio State just advised all staff and students not to attend the SACNAS (Society for the advancement of Chicanos and Native Americans in Science) annual meeting of 6000+ scientists -- which is in Columbus, OH this year! -- saying it may be exclusionary, even though it is open to all.

NSF has a new banner. (Per contingency plan, 75% of staff are furloughed and most agency activities will stop.)
Due to a lapse in appropriations, NSF is closed. NSF will continue to accept proposals in accordance with published guidelines. Please continue to watch this site for changes to NSF's operating status, reopening guidance for employees, and if necessary, general instructions for recipients.

He was the first professional physicist I had ever met, as a teenager at a science festival in Croatia. I asked him an overly wordy question in broken English and he was really kind about it. It felt like a huge deal at the time.

R.I.P. George F. Smoot (1945-2025)

We will no doubt read many official obituaries in days to come, but all I can say is that he was a character, a very original thinker, a fine scientist, and a very nice man. Along with many others, I will miss him enormously.
