Samples returned from the asteroid Ryugu contain all five canonical nucleobases (A, G, C, T, U). Their presence in Ryugu and Bennu supports the hypothesis that carbonaceous asteroids contributed to the prebiotic chemical inventory of early Earth. http://dlvr.it/TRWtVp ☄️

🚨 BREAKING: A federal judge has ruled in favor of @ameracadpeds.bsky.social and issued a preliminary injunction against the CDC. The ruling pauses the Jan 2026 childhood immunization schedule revisions, blocks RFK Jr's 13 recent ACIP member appointments, and pauses all votes taken by the committee.

fresh off the press from yours truly: oecs.mit.edu/pub/b61joemo... I offer an overview of algorithmic bias. I trace its historical roots, examine canonical scholarship and notable real-world incidents, and explore how algorithmic bias emerged as a field of study 1/

Just because it's being passed around a lot: NO, data centers in space do NOT benefit from space being cold. Space is cold in the formal sense we use to define temperature. But it is very bad at cooling. What would you rather have to cool hot metal: a lukewarm water tub or a giant cold atmosphere?

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia: doi.org/10.5281/zeno... We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical thinking, expertise, academic freedom, & scientific integrity. 1/n

Sports *are* political, especially when we have a peloton full of corporations and state-sponsored teams doing sportswashing. Maybe read what Sylvain Adams has said about his goals for Israel-Premier Tech

GOOD THREAD: One more consequence of too many parked cars in cities (and one more reason to replace surface parking with trees and people-places). All those parked cars are making hot cities even hotter. (at a minimum, choose a white car.) #UrbanHeat

There's a lawsuit about AI stealing your work. It's the same lawyers taking on Elsevier et al in a separate case. Academics: 1. Check if your work is in LibGen at www.theatlantic.com/technology/a... 2. If so, let the lawyers know at www.lieffcabraser.com/anthropic-au...

If Biden had taken 10% of Intel, at least it would have been in exchange for the billions in Chips Act funding granted to the company. Trump's taking this in exchange for deciding not to destroy the company. It's literal protection money.

“One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss.” “Which means that Copenhagen, a city of 1.2 million people, saves $357 million a year on health costs because something like 80% of its population commutes by bike.” #CityMakingMath Some costs aren’t costs.

“Not only does this contribute to cognitive deskilling, with the potential erosion of a student’s ability to write, reason and think critically, but it could contribute to social deskilling, if students are not attending classes, asking lecturers questions or sharing ideas with their coursemates.”

Paris keeps on giving! Rue Nationale in the 13th arrondissement has been transformed with new green space and protected cycle infrastructure. This is a great example of how cities are reclaiming space for people over cars. 📸 via @emmanuelspv.bsky.social on Bluesky

if you watch the tech industry long enough you learn the promised benefits never materialize but the unforeseen harms continue to be perpetuated long after the companies move on to the next big thing yet governments are too worried about scaring away investment to do anything

This is why education systems shouldn't chase "jobs of the future"....

Smart cities know that, as hot as they already are, they’re just going to keep getting hotter. Greening the city not only cools it down, it cleans the air, quiets the noise, improves mental health & happiness, saves public money, & more. Strand Aldwych, London. 2021 vs. 2025. Via @modacitylife.com

Once upon a time, two science journalists had an idea for a blog about retractions. And on Aug. 3, 2010, Retraction Watch launched. And now, 15 years and 6,700 posts later, that work seems more important than ever. Happy 15th anniversary, Retraction Watch.

One of the most unheralded parts of making streets safer for children is the amount of time it frees up for parents.

Silicon Valley’s alliance with Donald Trump was a mask off moment and showed the world we can’t depend on US tech companies. For the past few months, I’ve been trying to get off US tech and I put together a guide so you find alternatives too. I hope you find it helpful!

A Borges story about a guy who gets AI to summarize all the world’s information for him, and then summarize the summary, until the AI has the whole world summarized into a single word. He sits alone at his desk, staring at the word, repeating it endlessly, certain he is experiencing everything

The rapid deskilling that Ai seems to be causing is chilling. You watch people flounder when GPS isn't available. People who struggle with simple maths when they don't have a calculator. Now Ai seems to be doing this on a massive scale, across all kinds of skill sets.

You know all those programmers saying "AI is the future! It's made me so much faster"? Yeah, they're just bad at estimating.

The sheer weight of Russian social media propaganda is a thing to behold. Boris Rozhin, aka the warblogger colonelcassad, posted over 33,000 times on Telegram in 2023. It's relentless.
