This is pretty cool. How do you train an LLM? Yes but reeeeally how? This 200+ page (!) blog from @hf.co shows how to train a model from start to finish, bugs, warts & all. Loads of interesting details I hadn't thought about huggingface.co/spaces/Huggi...

Another day, another claim of quantum advantage -- this time, with hints of (someday) doing something useful 🧪⚛️ www.nature.com/articles/d41...

Where do the world famous LLM sceptic @garymarcus.bsky.social & his bud Laurence Fishburne (AKA Morpheus) like to hang out? The Royal Society of course! 🧪🤖 Here's my write up from @unisouthampton.bsky.social's Celebrating the 75th Anniversary of the Turing Test event www.nature.com/articles/d41...

Next week @jameszou.bsky.social & colleagues will host a conference where all the papers are written by AI agents & reviewed by them too. What do you reckon? A good chance to put AIs through their paces? Or a way to divert AI slop from elsewhere? 🧪🤖 My story here: www.nature.com/articles/d41...

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:

I'm pretty sceptical about 'AI scheming', as it's so easy to anthropomorphise & experiments often involve telling the AI to do the bad thing they end up doing. To understand what's behind the hype, read this smart & sober overview [email protected] 🧪🤖 www.nature.com/articles/d41...

Over at @naturepodcast.bsky.social we also made a super short vid on this year's physics Nobel Prize. Quantum phenomena at the macroscopic scale in two minutes... go! With me, and Ben Thompson & camera work by the fab @emzywb.bsky.social 🧪⚛️ www.youtube.com/shorts/krita...

John Martinis’ wife didn’t wake him in the middle of the night (California time) to tell him he had won a Nobel. “I got up a little bit before 6. Then I opened my computer and saw John and Michel’s and my pictures." Story by @lizziegibney.bsky.social and me www.nature.com/articles/d41...

Have you heard loads about "AI agents", but have little idea what they are, what they can do for researchers and whether to believe the hype? Then this is for you! 🧪🤖https://www.nature.com/articles/d41586-025-03246-7

Nature's news team is now recruiting for our paid US intern position for January to June 2026. It's a great opportunity to come join our team & publish important stories 🧪 Apply by 16 Oct springernature.wd3.myworkdayjobs.com/SpringerNatu...

I was going to post a rant about the perils of quantum computing hype, following the claim by #HSBC & #IBM that they have improved bond market predictions using a QC, but instead I will just link to Scott Aaronson's blog which says it all scottaaronson.blog?p=9170 🧪⚛️ cc @bullshitquantum.bsky.social

Also read @helenpearson.bsky.social & @heidiledford.bsky.social's excellent story unpicking the origins of Trump's paracetamol/autism claims www.nature.com/articles/d41... This quote sums it up: "We do not think that taking acetaminophen is in any way contributing to actually causing autism"

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 ⚛️🧪

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

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.
