🩸🩸🩸TODAY WE SHARE TWO MAJOR DISCOVERIES🩸🩸🩸 1. We peered into genomes and brains of the rare mosquitoes that QUIT feeding on blood and found what biting is built from 2. Humans got rid of isoleucine in their blood, malaria suffers from it, and mosquito proteomes budget for it THREADS>

FERAL is now agent-friendly! You can train and validate your model and analyze your animal behavior videos through your agent! Together with the introduction of FERAL lite in the previous release, we think this will make FERAL much easier to use! www.getferal.ai www.biorxiv.org/content/10.1...

Day 1 of the #ICN2026 Mosquito Satellite concluded with a session on vector control. In other words, how do we stop mosquitoes from biting us? @jacoporazzauti.bsky.social and @yoonjikim.bsky.social from the Vosshall lab talked about chemical deterrents and aging mosquitoes.

FERAL 1.0 is out! Just to remind you: FERAL is an open-source toolkit for supervised animal behaviour segmentation directly from videos with no pose estimation needed. We made it much easier to install and run FERAL First, to install FERAL: pip install feral www.biorxiv.org/content/10.1... 🧵

🎉 Thrilled to see our #MosquitoCellAtlas featured on the cover of @cp-cell.bsky.social ! This mosaic represents 367K cells across 19 tissues, unveiling the complex biology that makes mosquitoes the world's deadliest animals. Beautiful art by @somedonkey.bsky.social meets the #Vosshalllab science! 🦟🎨

A paper in Nature presents a suite of previously unknown features belonging to the oldest known fossil bird, Archaeopteryx. Analysis of the Chicago Archaeopteryx shows new information about the skeleton, soft tissues and plumage of this iconic taxon. go.nature.com/4jNZIJg #Paleosky 🧪
This is extended data figure 9, which shows a reconstruction of the plumage of Archaeopteryx by Michael Rothman.
