banning X is a national security issue for every country, plain and simple
its explicit goal is to amplify and empower the largest Nazi-adjacent party in every country in which it operates
it is also the largest deepfake porn generator in the world

So please enjoy this shrimp, filmed off Cozumel, Mexico. It may be a larval reef shrimp, but we don’t know what species or how long it lives or what it eats. The world is still full of wonder and beauty and mystery.

remembering that pitchfork was sold to conde nast with the understanding that conde would be good stewards of the publication. just reminiscing, is all.

One example of how Grok is being used to target women. Swedish Deputy Prime Minister Ebba Busch being sexualised, degraded, and humiliated step-by-step by Grok. All the images accurately reflect the prompts provided.

Thrilled to start 2026 with our latest preprint, in which we dive into a dedicated forward-walking circuit in the fly brain: doi.org/10.64898/202.... This effort was spearheaded by the fantastic @chrisjdallmann.bsky.social with help from a bunch of talented people in the lab.
How does the brain control locomotion? In our new preprint, we uncover a brain circuit in Drosophila that controls forward walking independently of turning. This dedicated locomotor circuit enables flexible motor control and might reflect a shared principle across species. doi.org/10.64898/202...
