Our latest discoveries—two of the loudest gravitational-wave signals ever: #GW240925 and #GW250207 Using these signals, and our understanding of binary black holes, we can verify that our detectors are correctly calibrated ligo.org/science-summ... 🧪⚛️☄️🔭

Now on @sciam.bsky.social: Astronomers are puzzling over what almost seems to be a time traveler in the early universe—a newfound “red monster” galaxy so big and dusty it shouldn’t exist at its cosmic epoch, a mere 400 million years after the Big Bang. www.scientificamerican.com/article/jwst...

This first woman beyond low Earth orbit is a Phillies fan—how beautiful

I wonder if it’s also a pink moon tn for the Artemis crew

Also in @nature.com's #ArtemisII coverage: "It is not sufficient to justify human space exploration by aiming to be the first or by claiming that it will support industry. How it is done, and by whom, needs to change to win the public over." - Bethany Ehlmann 🧪🔭 www.nature.com/articles/d41...

So this is where all the missing antimatter has been hiding

These medical X-rays are all deepfakes — and they fool even radiologists Radiologists and large language models alike have a hard time picking out real medical images from fake ones. @jennaahart.bsky.social writes for @nature.com News. With a quote by me. www.nature.com/articles/d41...

Most radiologists struggle to identify X‑ray scans that are generated by artificial intelligence, with fewer than half spotting synthetic images hidden in real medical data go.nature.com/4sty6NM

Contrary to what a grade-school science experiment might have you believe, static electricity is an utter mystery to scientists. In my new feature for @nature.com: why is static electricity so shockingly complex, and how are we finally getting consistent results in this field?

Many of the scientists Jeffrey Epstein courted were already well-established and well-funded. So why didn’t they all just say no? Science talked with three who did just that. Here’s how Epstein approached them, and why they refused to have anything to do with him. ⬇️ https://scim.ag/40qbXnv

Why do curling stones slide across ice the way they do? After a century of study, physicists have theories — but they’re still not 100% sure. Stellar lede from @jennaahart.bsky.social Read the full story in @nature.com: www.nature.com/articles/d41...

This is dehumanizing and normalizes a future when AI agents can literally boss humans around; with or without our awareness. Its the latter I'm more scared of! @jennaahart.bsky.social has a good piece on it: www.nature.com/articles/d41...

The Pandora satellite provides career training grounds while observing exoplanets go.nature.com/4tfz7dr

More than half of the Pandora mission’s leading scientists and engineers are early-career researchers This is “really unheard of elsewhere in the NASA mission space”, says one. By @jennaahart.bsky.social @nature.com 🧪 🪐 🔭 www.nature.com/articles/d41...

New for @nature.com: the early-career researchers behind NASA's newest telescope, Pandora. “People talk about having a seat at the table. I think that Pandora has taken a step further and helped early-career people be involved in choosing the menu of what we’re eating at the table.”

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:

Is this the elusive ultra-long GRB ???

babe wake up, an entirely new type of object just dropped

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. www.nature.com/articles/d41...

A consensus is emerging that these mysterious little red dots, sometimes called rubies, are an entirely new type of object in the Universe. go.nature.com/4hjIGm4

First exoplanet story since August—reclaiming my brand

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:

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. www.nature.com/articles/d41...

Of the 202 Nobelists who have been awarded prizes in physics, chemistry and medicine this century, less than 70% hail from the country in which they were awarded their prize, a Nature analysis shows. go.nature.com/48UbZJp

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. 🧪 www.nature.com/articles/d41...

"This detection will quickly 'become one of my favourites', says David Reitze, executive director of the LIGO laboratory" @jennaahart.bsky.social reviews some of our greatest discoveries, including the new #GW250114 in Nature News www.nature.com/articles/d41... #GW10Years 🧪⚛️🔭

Happy birthday to GW150914, our first (of many) #GravitationalWave discoveries, detected 10 years ago today! #GW10Years 🧪⚛️🔭 🖼️: @chirpmass.bsky.social

Ten years ago, the #LIGO gravitational-wave detectors in Louisiana and Washington first heard the ripples in spacetime created by some of the most violent cosmic collisions. For @nature.com, @jennaahart.bsky.social looks back at LIGO's greatest hits: www.nature.com/articles/d41... #physics 🧪

New from Nature: Latest LIGO results from GW250114 confirm Hawking’s black hole area theorem with 99.999% confidence!! “It was the perfect 10-year anniversary present.” More on this detection and LIGO’s other greatest hits from its first decade of discovery 🧪🔭 www.nature.com/articles/d41...

Amazing early birthday present for GW detections !!
