Check out our preprint! With new molecular mechanisms, 140 subtomogram averages, and ~600 annotated cells under different conditions, we @embl.org were able to describe bacterial populations with in-cell #cryoET. And there’s a surprise at the end πŸ•΅οΈ

Are you ready to lead ground-breaking research in Infection Biochemistry?

We are recruiting outstanding scientists to establish research groups based at @cssbhamburg.bsky.social tackling fundamental questions in molecular mechanisms of infection.

Exclusive: Famed protein structure competition nears end as NIH grant money runs out Agency silent on funding renewal for contest that inspired creation of AIs that predicted how proteins would fold

Speak up to prevent a major loss for the field. CASP, which helped shaping structural biology including AlphaFold is on the verge of shutting down. NIH funding has lapsed, UC Davis support ends and the core team is being let go. Painfully shortsighted.

Chris Russo’s group, inc. Joshua Dickerson, adapted #cryoEM to work at liquid helium temperatures (13 kelvins), where every frame captured contains more information than the equivalent using liquid nitrogen (81 kelvins).
