Ten math problems with proofs known the authors. Proofs are encrypted until Feb 13. For all problems, authors claim both AI-based literature searches and zero-shot attempts at proofs failed. If you want to take a crack, you have until next Friday (2/13)!

@mariaa.bsky.social and I have been building a custom client that we'd like to make public in the near-term BUT we want to make sure we've gotten the security right. Anyone with some expertise open to helping us out a bit?

"While almost everything that astronomers study occurs in the vacuum of space, astronomy itself does not 'happen in a vacuum'. Interactions between scientists, as well as outreach to members of the public, improve extensively from access to good communication tools." Paper day! ⤵️

For You has become the most liked feed: bluefacts.app/feeds/top Thanks everyone who gave it a like! Liking a feed may seem meaningless, but I think it does matter to the feed creators. It definitely has been motivating for me. Consider going over the feeds you have pinned and giving them a like!

Check out our new paper at #AAAI 2026! I’ll be presenting in Singapore at Saturday’s poster session (12–2pm). This is joint work with @shuvoms.bsky.social, @bergerlab.bsky.social, @emmapierson.bsky.social, and @nkgarg.bsky.social. 1/9

If you want to research or even just learn for yourself about "Social Media, LinkedIn, Facebook, Instagram, Youtube, WhatsApp, or Twitter," then yes, unfortunately, it's almost impossible to do that research externally. This is a big reason why Bluesky's open ecosystem is so exciting to me!

What's the point of doing science if you can't tell anyone about it? We are excited to announce @emily.space as another confirmed speaker for #ATScience!

Hello all! 👋 I’m delighted to share a 🚨 new preprint 🚨: “Active Evaluation of General Agents: Problem Definition and Comparison of Baseline Algorithms”. A paper thread! 🤩📄🧵 1/N

Excited to present a new preprint with @nkgarg.bsky.social: presenting usage statistics and observational findings from Paper Skygest in the first six months of deployment! 🎉📜 arxiv.org/abs/2601.04253

If you know people in Theoretical CS or adjacent who just joined BlueSky (or just did yourself), please tag them or say hi in this thread! #TCSSky (I'll follow them/you, let's strengthen our research community here)

🔈 Asu Ozdaglar and I are hiring a postdoc for next year to work on adaptive, ethically-informed decision systems, human–AI collaboration, and decision-making under uncertainty. More info here: charapodimata.com/postdoc_anno...

so so so excited to present our research + connect with the #ATScience community 🧪🎉

If you are a senior researcher (i.e., associate prof level or later), and you're interested in moving to the University of Waterloo (best CS program in Canada) for the Canada Impact+ Research Chair (biggest chair position in Canada, $$$$$), email me. Discretion guaranteed.

I'm going to start doing this every month to help new users dipping their toes in. If you post about AI research here, like this post. I'll follow you. (Like even if I already follow you, to help others find you too.)

That said, we know people want more safety tools, so @eugenevinitsky.bsky.social and I are building them! Here's what that looks like in our client. My post got a lot of interactions and then a big account reposted it, so alerts showed up and I have tools to deal with it. Give us more ideas!

@eugenevinitsky.bsky.social and I are looking for a few testers for something special we've been building! It's an app that lets you view the same content you see here on Bluesky but with extra features — some focused on researchers, some general upgrades. Reach out to us if interested!

back again to share a new preprint from me and @mantzarlis.com! “What did Elon Change? A comprehensive analysis of Grokipedia” arxiv.org/abs/2511.09685 I had seen many spot analyses of individual grokipedia pages, but I was curious: how was grokipedia made? what did Elon change from wikipedia?

I had a lot of fun making this map of Manhattan’s grid (only the numbered streets and avenues). Learned that 4th avenue doesn’t exist, but then learned that it actually does exist but only for a few blocks.

@bostoncollege.bsky.social is launching a PhD program in Computer Science! Help spreading the word to interested undergrads would be appreciated; our department has faculty research clustered in ML and CS theory, and Boston's a nice place to be :) www.bc.edu/content/bc-w...

I’m recruiting students this upcoming cycle at UIUC! I’m excited about Qs on societal impact of AI, especially human-AI collaboration, multi-agent interactions, incentives in data sharing, and AI policy/regulation (all from both a theoretical and applied lens). Apply through CS & select my name!

🧠⚙️ Interested in decision theory+cogsci meets AI? Want to create methods for rigorously designing & evaluating human-AI workflows? I'm recruiting PhDs to work on: 🎯 Stat foundations of multi-agent collaboration 🌫️ Model uncertainty & meta-cognition 🔎 Interpretability 💬 LLMs in behavioral science
