Check out MitoScribe, our new preprint led by @Linhan_W: https://t.co/rvNOSaMily... It's an analog molecular recorder that uses neutral base edits to the mitochondrial genome to store info about historical signaling in a cell. Single cell resolution at scale (see next post)!

Today we report Evo, a generalist foundation model for biology, on the cover of @ScienceMagazine. Trained on billions of DNA nucleotides, Evo was designed to capture two key aspects of biology: the multi-modality of the central dogma and the multi-scale nature of evolution.
