The White House website has been wiped clean, but thanks to @erichorvitz.bsky.social , all the Biden #PCAST reports are available below. I want to thank the #PCAST members, all of whom donated their time and expertise to helping policy be science-based. tinyurl.com/2acnv2nh

A protein's position in the genome in relation to other genes is informative about function, so a genomic language model can be prompted to generate
- toxin/antitoxin pairs
- anti-CRISPR proteins

+ a database of 120B synthetic base pairs

Protein language models excel at generating functional yet remarkably diverse artificial sequences.

They however fail to naturally sample rare datapoints, like very high activities.

In our new preprint, we show that RL can solve this without the need for additional data:

Here's Veo 2, the latest version of our video generation model, as well as a substantial upgrade for Imagen 3 🧑‍🍳🚢

(Did I mention we are hiring on the Generative Media team, btw 👀)

1/🧬 Excited to share PLAID, our new approach for co-generating sequence and all-atom protein structures by sampling from the latent space of ESMFold. This requires only sequences during training, which unlocks more data and annotations:

Introducing Biomolecular Emulator (BioEmu). We build on AlphaFold evoformer representation of protein sequence, then sample 3D structures from equilibrium ensemble with diffusion model. From this sample, we can compute states, probabilities and understand mechanisms.

This blog post by @drscotthawley.bsky.social provides a very accessible overview of flow matching / rectified flow and reflow, based on intuitions from physics, rather than starting from probability distributions. The visualisations and animations are excellent, and the whole thing is also a colab!
