Remember DeepSeek's R1 model that crashed the US stock market in Jan? DeepSeek has said it did not boost the model by training on OpenAI outputs. This and much more (eg $$ to train & technical details) revealed in the firm's peer reviewed paper out in Nature today 🧪🤖 www.nature.com/articles/d41...

ICYMI, this week I wrote about GPT-5 and the effort to stop LLMs from hallucinating, as well as saying they've done tasks they haven't. With web search to verify facts, finding citations is getting a lot better. But as soon as it's off, things can still go very wonky🧪🤖 www.nature.com/articles/d41...

OpenAI's new open-weight #AI model looks to be a powerful reasoner. It's small enough to use locally and they've done loads to make it available. But has it entered the game too late to become the go-to for researchers? Do ping me if you're trying it out! www.nature.com/articles/d41... 🤖🧪

Hey quantum fans. Here's a slightly different #quantum survey from my mind-boggling one on interpretations, but seems important! This group hopes to understand how to help quantum scientists to stay in the field & thrive. If you have time, you can fill it out here👇 www.diviq.org/survey 🧪⚛️

This year quantum physics turns 100, so @nature.com decided to conduct the biggest ever survey of what lies behind it. Do physicists really believe in multiple universes? Can influences happen instantaneously? Is the Copenhagen interpretation all it's cut out to be? ⚛️🧪 www.nature.com/articles/d41...

The Thirty Meter Telescope — long planned to be built in Hawaii but now with its US funding on the chopping block — could be given a new lease of life in Spain, following a government bid to host at the telescope on La Palma. Will the TMT board accept? 🧪🔭 www.nature.com/articles/d41...

Moonshot AI has now published its technical report about Kimi K2 github.com/MoonshotAI/K... The 32-page doc says the model trained on NVIDIA H800 GPUs, including post-training reinforcement learning on agentic examples My story from last week is here: www.nature.com/articles/d41...

Meet Kimi K2 from Beijing-based Moonlight AI. Good at coding, writing & multi-tool tasks, reports say it's the best open model available. It looks like #DeepSeek wasn't an anomaly. Sources said to expect more cutting-edge & free models from Chinese firms soon 🤖🧪 www.nature.com/articles/d41...

For this week's @naturepodcast.bsky.social we chatted about a news story on researchers putting hidden prompts into preprints to try to game peer review, and turned it into a 90-sec vid. Take a look here: www.youtube.com/shorts/WvamK... 🧪🤖 With @nickpetrichowe.bsky.social & @danjfox.bsky.social

"POSITIVE REVIEWS ONLY" Researchers are hiding instructions for AI peer reviewers in their preprints. I'm almost impressed by how much some of these researchers hide within a tiny white space. But it's far from clear how much of an impact such prompts have. www.nature.com/articles/d41... ⚛️🧪🤖

Thanks so much to the @absw.bsky.social for my award, and for the fantastic event last night. It was wonderful to hang out with such an excellent bunch of journalists! Congrats to the other winners & nominees. I will cherish my #bestmugintheworld forever!

Quantum tunnelling (when a particle goes through a barrier classical physics says is impossible) happens quicker the less energy it has. Huh? Physicists behind this cool experiment say the findings challenge Bohmian interpretations of quantum mechanics ⚛️🧪@nature.com www.nature.com/articles/d41...

Trump team axes contracts with publishing giant Springer Nature At first, NIH told me its contracts with SN were active and that they help “advance scientific discovery”. Hours later, HHS said the opposite: "Precious taxpayer dollars should not be used on unused subscriptions to junk science.”

New research shows the pipeline from #AI research to #surveillance applications, using 30 years of data from CVPR papers www.nature.com/articles/d41... In a related editorial we argue that researchers need to avoid sleepwalking into a future they might not like www.nature.com/articles/d41... 🧪🤖

Also an awesome video from my colleague @nickpetrichowe.bsky.social here www.youtube.com/watch?v=g9Jt... (and the paper is here: www.nature.com/articles/s41...)

Using #AI to do your #physics homework is like using an electric scooter on a treadmill. medium.com/@rjallain/th...

NEW: NSF will be kicked out of their building. Announcement will be made tomorrow by HUD Sec. and Governor of VA. HUD will take over the NSF building over the next two years. NSF staffer: "There is no planning for NSF, no identified future location, appropriation for a new building or a move."

Last week I was lucky enough to go to Heligoland for a massive quantum shindig. I asked some incredible physicists & philosophers why we still can't agree on what quantum mechanics tells us about reality ⚛️🧪 [email protected], @gemmadlc.bsky.social & more www.youtube.com/watch?v=9QcN...

After ruling the NIH grant cuts were illegal yesterday, Judge Young, a Reagan appointee on the bench since 1985, ended the hearing with a blistering 15-minute speech. I've cleaned up my notes — here are his remarks in full. 🧵

From today, all new submissions to Nature that are published will be accompanied by referees’ reports and author responses — to illuminate the process of producing rigorous science https://go.nature.com/4kIRR01

Reposting to the physics education feed since oh boy is that a nice intro to talking about refraction effects in water! ⚛️🎢

Can one particle instantaneously affect another? Is nature truly random? And did Heisenberg also get seasick?? Some musings on my weird and wonderful week on the island of Heligoland ⚛️🧪 www.nature.com/articles/d41...

In case you missed it on Friday: my story about Trump's proposed NASA cuts & how, if they pass, they'd deal a massive blow to international collaboration. Europe's long-planned ExoMars rover could be a huge casualty. But Washington's reputation would be another. www.nature.com/articles/d41... 🧪🚀

Bye bye to an excellent anomaly, we will miss you ⚛️🧪

Anyone with hot science journo skills want to come and edit my stories? In @nature.com's European bureau we're looking for a locum news editor, based in either London or Berlin, on a 9 month contract.

And if you'd rather watch a video than read my story on nanoparticle-infused contact lenses that let you see in the infrared, you're in luck! We made a quick one here (with @shamini.bsky.social & @danjfox.bsky.social) www.youtube.com/shorts/aBulp... ⚛️🧪

I have some become "new cool ways of seeing things" correspondent @nature.com, which I'm rather happy about. These may not yet be a patch on night-vision goggles, but these nanoparticle-infused lenses do give you a touch of the super human. Have a read here: www.nature.com/articles/d41... ⚛️🧪

🥳Happy 150th birthday to the Metre Convention!🎂 How do you know how long a metre is?📏 Because of global cooperation to set a standard — starting from the Metre Convention in 1875 Shanay Rab & Richard Brown explain why we still need this kind of collaboration rdcu.be/emM59 ⚛️ #worldmetrologyday

The papers all follow a similar template and make misleading claims https://go.nature.com/4kucwEH

Very honoured by the @absw.bsky.social nomination for my piece on CERN's future without Russia ⚛️ www.nature.com/articles/d41... Huge congrats to all the finalists including @nature.com's @shamini.bsky.social, @danjfox.bsky.social @helenpearson.bsky.social & Nisha Gaind (who also edited the above!)

DeepMind's @matejbalog.bsky.social & colleagues have come up with a seemingly simple but successful technique to improve algorithms in computer science & maths: an LLM comes up with ideas that an evaluator critiques against metrics. Repeat until you've nailed it. 🧪🤖 www.nature.com/articles/d41...

I spoke with OpenAI's chief scientist Jakub Pachocki about the firm's upcoming open-weight models, the importance of reinforcement learning and how the ability to make scientific breakthroughs is his gauge of AGI www.nature.com/articles/d41... 🧪🤖

Hello, if you came to this Bluesky post through a verification link in an email from me, this is to confirm that I'm Lizzie Gibney and did email you the survey you've received. I look forward to your views!

Physicists @cern.bsky.social have turned lead into gold 🏅 🧪⚛️ OK so it was using a billion-dollar particle accelerator & they made less than a nanogram's worth... but still, pretty cool! Studies like this can help physicists make better particle beams. www.nature.com/articles/d41... #Fridayphysics

The intro to this feature so deftly lays out the scale of Trump's impact on science (and is one that just months ago I could never have imagined reading). One of the many stories by our US team that make me proud to work @nature.com www.nature.com/articles/d41...

NEW: An NIH policy coming in the next week will target — and at least temporarily stop — funding outside the US, threatening thousands of projects and collaborations on topics like infectious diseases and cancer. Some NIH staff have already been told to hold all subaward funds for foreign labs.

In case you missed it, here’s my quick explainer on last week’s news about the new colour “olo” 🧪 Colour is all in the way our brains interpret signals from the eye’s cone cells, and scientists have found a whole new way to stimulate them youtube.com/shorts/A-ywx...

An exclusive @nature.com analysis sees the first real signs of a US science brain drain (by our excellent careers team) ⚛️🧪 www.nature.com/articles/d41...

Researchers have made a never-before-seen colour ‘olo’ - an impossibly intense green-blue that's literally off-the-charts. The technique from @ucberkeleyofficial.bsky.social &@roordalab.bsky.social can also create full colour vision with a single laser 🧪 www.nature.com/articles/d41586-025-01252-3

Research in plasma wakefield acceleration has been hotting up over the last decade. Given the long time lines involved in building new colliders, should we be considering where this technology could fit in? 🧪⚛️ www.nature.com/articles/d41...

Yet once more way that Trump's policies are impacting science 🧪

Take Nature’s poll - the new administration is reshaping the research landscape in the United States in profound ways. What do you think of all the changes? @nature.com www.nature.com/articles/d41...

NEW: After cancelling nearly all projects on trans health, the Trump admin has now directed the NIH to study the negative consequences of transitioning. This will create “a distorted research ecosystem where only politically favorable findings are permitted to exist”, researcher Harry Barbee says.

The @esa.int Gaia spacecraft was moved out to a graveyard orbit and decommissioned today — but much of its discoveries are yet to come. Here is a 🧵 to recall milestones in the (still ongoing, but still with no Bluesky account?!) project

Today we say goodbye to ESA’s Milky Way-mapper Gaia! The Gaia spacecraft has completed its sky-scanning and will be switched off this morning.

This is such an amazing study. Researchers tracked people over 300,000 births looking at how biomarkers change & recover postpartum. ~60% stabilise close to pre-conception levels after 3 months, but some (eg for bone & liver health) take a year. Others never recover! 🧪 www.nature.com/articles/d41...

Scientists have, for the first time, spotted a difference how antimatter and matter baryons (the same family as protons) decay. The finding by @cern.bsky.social's @lhcb.bsky.social could help in efforts to unravel the mystery of why anything is here at all ⚛️🧪 www.nature.com/articles/d41...

Heard about that French scientist who got turned away at the border? @heidiledford.bsky.social & I report on researchers' increasing anxiety about traveling in or out of the US: 🧪 www.nature.com/articles/d41...
