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.

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

The first full year of tracking research on @bsky.app
Hi, we are Altmetric, and we track how research is communicated across the web.
We now have one full calendar year of Bluesky research data and thought we'd have a looksie.

HOW WILL WE LEARNE THINGES?
Uh, what about bookes, filmes, teachinge, educacioun?
HOW ABOUT WE MAKE A MACHYNE THAT DOTH KNOWE STUFFE
Uh, what about bookes, filmes, teachinge, educacioun?

YEAH THE MACHYNE
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?

Abstract: Under the banner of progress, products have been uncritically adopted or even imposed on users — in past centuries with tobacco and combustion engines, and in the 21st with social media. For these collective blunders, we now regret our involvement or apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not considered a valid position to reject AI technologies in our teaching and research. This is why in June 2025, we co-authored an Open Letter calling on our employers to reverse and rethink their stance on uncritically adopting AI technologies. In this position piece, we expound on why universities must take their role seriously toa) counter the technology industry’s marketing, hype, and harm; and to b) safeguard higher education, critical thinking, expertise, academic freedom, and scientific integrity. We include pointers to relevant work to further inform our colleagues.
Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI (black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf. Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al. 2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA).
Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

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.

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.”

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.

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"....
