In this episode, we discuss the fact that a globular cluster stream has finally been found in an external galaxy 🤩 it's not just pretty, it also lets us measure the halo mass of the galaxy. Tune in on starxiv.com to hear more 🔭🧪☄️

Michelle discussed the first ever detection of a globular star cluster in an external galaxy, and what it can tell us about the dark matter in this system. Tune in on starxiv.com for more! arxiv.org/abs/2608.12254 🔭 ☄️

HST image of the ultra-diffuse galaxy and its detected stream. The galaxy is a faint, aprtially resolved system, and just away from its centre is a small point of light - a globular cluster - with a thin trail coming out from its side. This is the new stream that was detected.

tl;dr We found a globular cluster stellar stream candidate in another galaxy! If this holds up, this will be an important new chapter in stellar stream and dark matter research. (w/ @spacewsarah.bsky.social @jakenibauer.bsky.social and more) www.nature.com/articles/s41...

Cory Doctorow was interviewed by Anna Foster on BBC Radio 4 Today on the topic of AI. I've captured a transcript of the questions here in a short thread (with the help of Google AI voice-to-text. Good AI, thank-you.) 1/5

AF: We could spend the whole of the rest of the day talking about AI but sometimes we need focus… CD: Oh God, must we? AF: We must, we must and while we decided to focus on this idea of a crisis of control, do you think that there is one? CD: I think AI is the money-losing-est thing the human race has ever done, I think it's grossly oversold and I think that the capital markets have lost their minds because of the confluence of large tech monopolies that have saturated their markets and need to convince investors that they can keep growing despite the fact that they have 90% market shares and the fact that they have a large customer base of bosses who are just infinitely excited at the prospect of firing mouthy workers who know how to do things that they don't know how to do and replacing them with software that compliantly does whatever it's told.

NEW: A lot of bad has happened to American science over the last year but nothing comes even close to what’s about to happen if we don’t speak out in opposition to the OMB rule changes and I hope @aaas-socsci.bsky.social @apsphysics.bsky.social and others will launch public campaigns about this. 🧪🔭⚛️

It's the End of American Science As We Know It

We have 45 days to express our opposition to catastrophic changes.

I was just talking about this. AI in a robust social safety net is very different than AI in a scam economy without one.

Dare Obasanjo@carnage4life.bsky.social · 3mo ago

A key reason people in China are more receptive to AI than in America is that the courts there have ruled that you can't just lay people off because Claude can now do research and write code. You need a better reason than that. In America, CEOs can't wait to get rid of "low value human capital".

THE ASTROPHYSICIST (2008) 
Acrylic - 24" x 36" When I started this painting, the major theme concerned the power of the human intellect to light our way into the universe. 
 The balls in the picture came from a conversation I had with my son Adrian. 1/5 #art #bookssky 🪐📚

In a desolate parking lot, a young man in jeans and t-shirt lies back on a grassy island to shine a spotlight straight up into the night sky. Sparsely stippled, the heavens are awash in celestial vision as if touched by the clouds of a nebulae, rendered delicately in lavender over dark blue. Power runs from the light the man holds to a nearby car battery where jumper cables are clamped to the terminals. Fanned facing down, a book lies discard on the curb next to a soccer ball, which lies in the grass just beyond the man's head. Below the curb at his feet, a basketball rests on the cracked blacktop.

i will keep reiterating it but the mRNA vaccine is one of the most important human inventions in history, next to the printing press and the solar panel, and the fact america is abandoning it is frankly anti-human in all ways possible

"Pancreatic cancer mRNA vaccine shows lasting results in an early trial: Scientists caution that more research is needed, but nearly all of the patients who responded to the personalized vaccine are still alive six years later."
