We can use a harmless wavelength of light to kill nearly all airborne pathogens. The technology exists! It works! And now there is a plan for bringing it out into daily life.
Far UVC can cut airborne bacteria by 98.4 percent, and could do the same for viruses, preventing diseases spread in public spaces. But it is held back because it is unpatentable, which means it is unproven, unregulated, and untrusted. We can fix this. worksinprogress.news/p/flipping-the…
maybe a better headline would be that oai and gdm ranked 27 at the IMO. some talented kids here!
This is the most scaling-pilled project I've ever been part of, and the team really cooked. TL;DR: With RL and inference scaling, Gemini perfectly solved 5 out of 6 problems, reaching a gold medal in IMO '25, all within the time constraints of 4.5hr.
An advanced version of Gemini with Deep Think has officially achieved gold medal-level performance at the International Mathematical Olympiad. 🥇 It solved 5️⃣ out of 6️⃣ exceptionally difficult problems, involving algebra, combinatorics, geometry and number theory. Here’s how 🧵

We desperately need to take all the people in SF who talk about accelerating biology but have only ever done math or CS and have them do a six month rotation in a wet lab.
“Finally, maybe this is controversial but ultimately progress in science is bottlenecked by real-world experiments.” If this is controversial in SF, we’re cooked.
Very excited to share this resource that @AdamMarblestone and I have been working on for the past few months! It’s an interactive map of scientific problems and potential solutions. What’s most exciting? What’s missing? Let us know! 👇
we made a map! gap-map.org is a tool we built to help you explore the landscape of R&D gaps holding back science - and the bridge-scale fundamental development efforts that might allow humanity to solve them, across almost two dozen fields
LLM evals have the glaring blind spot of being focused on "things AI researchers understand". I appreciate people like Adam using their expertise to help, like in this post on evaluating how useful LLMs are at instructing on how to make metal parts. Spoiler: They're terrible
New blog post! I conduct a detailed case study on manufacturing this simple brass part with frontier AI models. Spoiler: All models except Gemini 2.5 have horrible visual abilities, and all models fail at the physical reasoning tasks. I speculate on what this means. 🧵
There's just no evidence for the lab leak, and quite a lot for zoonosis. (I used to engineer viral vectors for a living.) The rootclaim debate with Peter Miller and Saar Wilf is long but the best public airing of the evidence. youtube.com/channel/UCAkFd…
In their roadmap, Microsoft described a protocol for demonstrating a topologically protected qubit. There is no publicly available evidence that this test has been conducted successfully. I hope we will hear more soon. arxiv.org/abs/2502.12252
Sharing to see if someone can help. @srikosuri is searching for clinicians or patients that have encountered pediatric interdigitating dendritic cell sarcoma (IDCS). Leads would be appreciated.
It’s been a tough few weeks. My 10yo daughter was diagnosed with a very rare, aggressive cancer called interdigitating dendritic cell sarcoma (IDCS). I’m reaching out to identify clinicians/patients who have encountered pediatric IDCS, indeterminate dendritic cell histiocytosis…
Making LLMs run efficiently can feel scary, but scaling isn’t magic, it’s math! We wanted to demystify the “systems view” of LLMs and wrote a little textbook called “How To Scale Your Model” which we’re releasing today. 1/n
Anyone – of any race, creed or nationality – who came to America and worked like hell to contribute to this country will forever have my respect. America is the land of freedom and opportunity. Fight with every fiber of your being to keep it that way! 🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
if you could press a button that cures your child’s brain tumor in exchange for ending your life immediately, every parent would hesitate for zero seconds before fighting to be the first to press it the cruelest thing is that no such button exists. but there is always a move 👇
Musk is correct. The United States has an extreme shortage of high-IQ workers. marginalrevolution.com/marginalrevolu…
Your understanding of the situation is upside-down and backwards. OF COURSE my companies and I would prefer to hire Americans and we DO, as that is MUCH easier than going through the incredibly painful and slow work visa process. HOWEVER, there is a dire shortage of extremely…
This is not a fact. It is only true if you are reasoning very short term. The bulk of everything good long term comes from research. But research looks quite unproductive short term. If you take what you say too seriously, you'll cause more harm in aggregate over the long term.
what I meant here is that we do not use our full understanding of physics to build a weather model. you approximate a handful of effects on a coarse area and run the engine. this doesn’t mean that deep learning is more true than physics, it means that running detailed physical…
Another day another tool. JAX Rooflines! When evaluating different chips or topologies for a workload you have to use a bunch of rules of thumb and flops/bandwidth calculations to arrive at relative performance numbers. Now you can free some brain flops and let JAX do the math…
