Does the Moon look a little extra bright tonight? It's not just you! 🌕 Tonight's full Moon is a "supermoon." It's slightly closer to Earth than average, so it appears just a bit bigger and brighter than usual. Here's how it works: https://t.co/Wmc7t6BE1A

Almost 10 years after the first detection of gravitational waves, physicists have announced the strongest such signal yet. Produced when two black holes in a distant galaxy spiraled into each other, the merger enabled researchers to test Albert Einstein’s theory of gravity,

Introducing quickarXiv Papers are often written in convoluted language that is hard to understand. We're fixing that. Swap arxiv → quickarxiv on any paper URL to get an instant blog with figures, insights, and explanations. Now extracted with DeepSeek OCR 🚀

Adult human brains have between 86-100 billion neurons and every single one is unique - like snowflakes! ❄️ In this 3D rendering by our #ElectronMicroscopy team, we see 3 different shapes incl. (from left to right) a basket cell, tufted excitatory cell, and a Martinotti cell.

Neural networks were conceptually invented in 1943 by neurophysiologist Warren McCulloch and logician Walter Pitts. They proposed a simple mathematical model of a biological neuron that could take binary inputs and "fire" if the sum exceeded a threshold. They proved that networks

One year ago, alphaXiv launched as a site for comments on arXiv papers. Since then, they’ve introduced AI tools like paper blogs and chat on papers, now used by millions, along with communities—a Discord-like social space for researchers. Cheers to another year of @askalphaxiv

Our open models are here. Both of them. https://t.co/9tFxefOXcg

Scaling up RL is all the rage right now, I had a chat with a friend about it yesterday. I'm fairly certain RL will continue to yield more intermediate gains, but I also don't expect it to be the full story. RL is basically "hey this happened to go well (/poorly), let me slightly

📢New conference where AI is the primary author and reviewer! https://t.co/iRy3tzaQkC Current venues don't allow AI-written papers, so it's hard to assess the +/- of such works🤔 #Agents4Science solicits papers where AI is the main author w/ human advisors. 💡Initial reviews by

Thrilled to finally share what we've been working on for months at @huggingface 🤝@pollenrobotics Our first robot: Reachy Mini A dream come true: cute and low priced, hackable yet easy to use, powered by open-source and the infinite community. Tiny price, small size, huge

We are delighted to share our new paper from @ACSPublications, where @UofG_MCMP's @DrTrev_Almeida and collaborators demonstrate the stabilization of skyrmions and skyrmioniums in curved magnetic nanocaps 🔬 🧲 🥳 The field sure has taken a turn!! 😄 https://t.co/phzcBVLADi

When Roger Penrose goes for a walk you might expect him to be thinking about cosmology etc. But he isn't. At least not always. Sometimes he is thinking about the walk itself. And the mathematics of it. Because Roger has his obsessions. Like lots of us.
