Very interesting @latent.space Podcast with Mark and Priscilla! Our cell tracking data is spinning on a screen in the background... www.latent.space/p/biohub
Building open AI to cure or prevent all disease by 2110 (w/ Mark Zuckerberg and Priscilla Chan)
The CZI has acquired EvoScale, established the first 10,000 GPU cluster for bio research, open sourced the largest atlas of human cell types, and gone all in on AI x Bio for its 2nd decade.

Mind-bender: The observable universe has ~10^80 atoms. But even a simple 1000×1000 black‑and‑white image has 2^{1,000,000} ≈ 10^{301,030} possibilities — and 24‑bit color explodes to ~10^{7,224,720}. The space of (small) images dwarfs the cosmos. 🔬🧪💻

Day four of #LISH25 begins with a powerful presentation by @loicaroyer.bsky.social on digitizing zebrafish development, combining light-sheet and single-cell data. Loïc took the #walk-up song to another level, improvising on the piano as his massive fish development visualisation played. Beautiful.

Production has started for a new #Snoutscope objective, AMS-AGY v3. It has significantly larger FOV and some other tweaks from v1 and v2. Currently accepting pre-orders. The price will need to increase modestly after deliveries start late October.

Just pushed a 'hot fix' version (2025.6.25.2) of Omega (napari_chatgpt) that addresses some issues introduced by the ever-changing model lists from #OpenAI.

I just asked #Claude 3.7 to make a web version of the 'Global Thermonuclear War' game from the classic #WarGames movie from the 80s. And it is not too bad!! Except for its skills at drawing continents... Game play could be more engaging too... haha.
