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 🧪⚛️

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."

Groundbreaking quantum-tunnelling experiments win physics Nobel
John Clarke, Michel Devoret and John Martinis discovered quantum physics on a macroscopic scale, paving the way for quantum computing.

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
A scientist’s guide to AI agents — how could they help your research?
Researchers are increasingly turning to artificial-intelligence tools that can handle complex, multi-step processes.

Is there a reason we picked this slightly terrifying still? 🤣
lizziegibney.bsky.social
I'm sure there's valuable science in there but experts I consulted were not super convinced by the paper (why does it work better with noise? Why didn't they compare to the best available classical algo?) We won't cover it. Alas others already have&without outside comment www.ft.com/content/d9d4...

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"

And here's Nature's take on why more AI developers should follow suit and put their LLMs through the peer review wringer. The process is far from perfect, but it seems a valuable counterbalance against AI hype and good for clarity & safety www.nature.com/articles/d41...
Bring us your LLMs: why peer review is good for AI models
Deepseek’s R1 model has been peer reviewed. Others should follow the firm’s example.

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...
Secrets of DeepSeek AI model revealed in landmark paper
First peer reviewed study shows how a Chinese start-up firm made the market-shaking LLM for US$300,000.

The top line is we're never going to get rid of hallucinations as it's just the way LLMs are built: they're not understanding, they're guessing based on stats. But maybe LLMs can be better fine-tuned to sound less confident, so humans aren't so taken in by them & use them more appropriately?
lizziegibney.bsky.social
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...
Can researchers stop AI making up citations?
OpenAI’s GPT-5 hallucinates less than previous models do, but cutting hallucination completely might prove impossible.

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!

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 🧪⚛️

Oh & THERE'S A QUIZ! In the vein of "what Spice Girl are you?" from a 90s issue of Bliss, just answer a few questions (in the story www.nature.com/articles/d41...) & we will tell you which quantum interpretation you are (& do let me know which one you think correlates with which spice girl 😂)

Please read, share and disagree with my write up in the spirit of Bohr, Einstein and the best in quantum physics 😃All the data is also available to download, if you'd like to analyse it yourself.
lizziegibney.bsky.social
Thanks also to the organisers of the Helgoland2025 conference who helped distribute the survey, to the +1,100 people who kindly responded & to editor extraordinaire @richvn.bsky.social, who learned far more about quantum foundations than he ever wished to & it would have been impossible without 🙏
lizziegibney.bsky.social
We asked a bunch more in-depth questions in a survey crafted in consultation with experts @fdlevi.bsky.social @seanmcarroll.bsky.social @philipcball.bsky.social Renato Renner & Elise Crull, to whom I am extremely grateful (& who all put up with me badgering them repeatedly over the last few months)
lizziegibney.bsky.social
I found it fascinating to unpack how there is so much disagreement, given that everyone is working with the same equations. As Renner put it, each interpretation has its faults & the price someone is willing to pay comes down to something personal. “It’s a very deeply emotional thing,” he says.
lizziegibney.bsky.social
But epistemic approaches, which say quantum states capture information or knowledge rather than anything real, seem to be growing in prominence at 17% (+4% for @rovelli.bsky.social's relational quantum mechanics). "Many worlds" had a strong following at 15% & lots of folk had their own explanations
lizziegibney.bsky.social
It may be no surprise to some, but we found there exists a LOT of disagreement, even among the most eminent in the field, about what quantum mechanics means for reality. The survey revealed that 36% of respondents favourite the traditional Copenhagen interpretation (particularly experimentalists)
lizziegibney.bsky.social
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?
