New: Researchers are broadly rejecting the Trump administration's compact. In faculty votes and student protests, they have mobilized to pressure their universities—to some effect: 6 of the original 9 universities have rejected the compact

With @alexwitze.bsky.social and @jennaahart.bsky.social:
How scientists are pushing back against Trump’s funding ‘deal’ for universities
Six institutions have so far rejected the administration’s list of demands over academic freedom concerns.

Is this the elusive ultra-long GRB ???

What would it look like if a black hole devoured a star from the inside? NASA's Fermi space telescope may have spotted the answer: a 7-hour blaze of gamma rays, unlike anything seen before.

When we explore, we discover amazing things. 🧪🔭

The Fermi Gamma-ray Space Telescope identifies and studies nature’s high energy particle accelerators, black holes. Fermi uses these sources to probe important physical parameters of the galaxy and the universe and uses high-energy gamma-rays to search for fundamentally new phenomena.

ICYMI: Astronomers are finally solving the mystery of JWST’s little red dots, and they seem to be a hybrid sort of black hole star!! 🔭🧪

“It’s almost a shame that we’re starting to figure them out,” Anna de Graaff told me.

Mysterious ‘little red dots’ are baffling astronomers. What are they?
A consensus is emerging that the dots, sometimes called rubies, are an entirely new type of object in the Universe.

Not common to see a 7-byline story in the wild, but that's what the situation calls for when the government shuts down and every science agency needs to be checked in on for RIFs, grant terminations, and general dysfunction.

Our update on what the chaos means for science here:
Scientists lose jobs and grants as US government shutdown takes a toll
Hundreds of people at the US Centers for Disease Control and Prevention have received layoff notices, and work at many federal laboratories has been suspended.

Who said the science part of Nobel week is over!? In my new analysis for Nature, over 30% of science laureates from this century have immigrated, and two thirds came to the US.

You've probably heard how a high percentage of #Nobel laureates are immigrants. The US in particular has benefited from the influx of bright minds.

@jennaahart.bsky.social ran the data for this century's Nobel prizewinners — and shows more than 30% immigrated. 🧪

In the latest from @nature.com: Could AI take home a science Nobel—no human needed?

Some say yes, and soon. 🧪

That's quite the chart annotation.

www.nature.com/articles/d41...
A chart of "Major concerns of PhD candidates." The top text says, "Financial pressures top the list of concerns faced by PhD candidates, but concerns differ among the sexes. Those studying in the United States rank the political landscape as their main worry." The chart shows that in the full survey, political landscape is the biggest concern for about 20% of students (a bit higher for women than men) but there's an annotation saying "In US PhD students, this rose to 64%". Overall, the highest-rated concern was financial pressures at around 40%.
