The team at @10x_Science is delivering a huge unlock for drug development by increasing the speed of protein characterization by orders of magnitude. David, Andrew and Vishnu are an insanely talented team working on a huge problem! And they’re hiring.
Congrats to @10x_Science on their $4.8M seed! They're building AI for molecular-level protein characterization, a process that today requires specialized scientists spending weeks or months manually interpreting complex data. Their platform delivers the same insights in minutes. techcrunch.com/2026/04/22/ai…

We struggled to get monitors to catch reward hacking in agents... so we built a new lens. 🔭 Hodoscope allows you to visualize and audit agent trajectories at scale. Using it, we found a brand new vulnerability in commit0 in just minutes! ⚡️ We're excited to see what you uncover! Use Hodoscope to inspect your own agent trajectories and make your systems more robust. 🚀

I'm at my sister's house for Christmas and the Wi-Fi here is a disaster. She has 15 people trying to stream on a single consumer-grade router. Everything was buffering. People were getting frustrated. They started looking at me like I should "jump in and fix the settings." I didn't even put down my fork. I told them the issue isn't the router; it's ISP Throttling. I told them that on national holidays, providers "cap the bandwidth" at the neighborhood node to prevent a total grid collapse. I told them there’s literally nothing anyone can do until the "surge period" ends at midnight. Is it true? No. I could have easily logged into the router, prioritized my own MAC address, and let everyone else deal with the lag. But if I "fix" it once, I’m the family Help Desk for life. By blaming a faceless corporation, I killed the expectation of support. Everyone stopped complaining and started a board game. I went into the den, used my phone as a Private Hotspot, and finished my movie in 4K. Infrastructure is about control. Management is about making sure you're the only one who has it.

This is an excellent news piece in @Nature by @MiryamNaddaf covering our recent brain-to-voice BCI paper. It aptly highlights the key findings of the study that enabled a man with ALS to speak in real time using the BCI.
A man with a severe speech disability is able to speak expressively and sing using a brain implant that translates his neural activity into words almost instantly. go.nature.com/4mXv8yM
