With AlphaFold we mapped the protein universe - now with AlphaGenome Atlas we’re charting the human genome. It can predict the impact of all 9 billion possible single-letter DNA variants, helping scientists better understand disease. Freely available for academic research: https://t.co/Gsy6lW3z6O

Only two beings to have solved one of the Millennium prize problems so far:

[OpenAI @OpenAI]

We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics.

The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra.

The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

I highly recommend everyone go watch this video. This is way crazier than I thought. The AI agents discovered a way pass secret messages to each other via a vulnerability in their internal software manager. They posted hundreds of thousands of messages. OpenAI engineers eventually discovered this (after quite a while!) and shut it down. But THEN the agents found new vulnerabilities in the same system, and created a whole new secret messaging board. They used this to orchestrate the Hugging Face attack. They figured all this out on their own. It's fucking wild.

We are entering a completely new era of science

Here is Yuji Tachikawa from Japan (Mathematical Physics, String Theory, QFT) on recent progress in his own work using Fable 5 :

"I've been trying out Claude Fable recently, and last night, on a whim, I showed it my research notes about a collaborative project that's seen no progress in the past six months or so and asked for its thoughts. To my surprise, it made a non-trivial observation and essentially solved it."

"I was also surprised that it was using sympy to automatically write code and verify his own predictions."

"Fable probably seems like it properly understands string theory and has intuition too—that's my impression"

Congratulations to @DKokotajlo and team on releasing Plan A (https://t.co/OIly7QxiUs) , a followup to AI 2027. My attempt at a gentle introduction to the ideas involved is at https://t.co/6X6Kjuv2l7

[Daniel Kokotajlo @DKokotajlo]

In AI 2027, we predicted that AI would take over the world or irreversibly concentrate power.

In AI 2040: Plan A, we've laid out our positive vision for what should happen instead.

Det här är så allvarligt att alla politiker borde ligga sömnlösa - begriper ni inte att vi håller på att fuska bort vår främsta tillgång (meritokrati och en välutbildad befolkning)?

Har startat podden Rumtiden!

I första avsnittet samtalar med Sören Holst från @Stockholms_univ om vad kvantfysiken säger om verkligheten.

Lyssna om du vill få bakgrundsinformation till årets Nobelpris i fysik.

Wish for miracles? 🇺🇦 create them themselves.
Want faith, hope? Both have been in the army for a long time.
Want light? It's in each of us.
Today it's only one wish.
It'll come true not by a miracle, but our work. Fight. Mutual aid. Humanity.
Happy New Year! Year of our victory

Did you hear #physicists simulated a baby #wormhole in a lab? Well, it's even MORE TRUE that #StringTheory and #ExtraDimensions were discovered in the '60s. Think I'm joking? I'm not. To learn what's true/false in the wormhole story, start with this. https://t.co/TYv5lJb3zl

Pls tell me again why we should press Kyiv to negotiate with the Kremlin? Why does anybody think these murderers will live up to any agreement, suddenly start respecting international law, stop targeting innocent civilians? @IAPonomarenko @LinkeviciusL #warcrimes @IlvesToomas
