I'm excited to share our new preprint: Generation of a transgenic cephalopod tinyurl.com/pc86jxz8 Cephalopods (cuttlefish, octopus & squid) are crazy critters that dynamically camouflage to their surroundings by changing the color, pattern, & texture of their skin, which they control w their brain.

NIH grants have been under political scrutiny since early 2025. But what does the screening process actually look like? What is being flagged? I spent a month digging into leaked docs and emails. We've published the 235-word list that are being flagged by an internal AI tool. And so much more. 🧵

Inside the new political screening that’s stalling NIH grants
Mandatory reviews by top health officials and checks for 235 disfavoured terms have left hundreds of vetted grant applications in administrative limbo.
