My group at @zmbp-tuebingen.bsky.social is offering a post-doctoral position (4 years). We look for a structural biologist with experience in Cryo-EM/Cryo-ET to investigate the mechanisms of host invasion by pathogenic fungi. Deadline February 28th!

LLOMe has long been used to study lysosomal damage, yet how it works has remained a mystery.
Using cryo-electron tomography, we show it forms amyloid structures inside lysosomes that mechanically rupture membranes – revealing a new paradigm for lysosomal failure.

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.

Hey #teamtomo, if you often find yourself using the excellent membrain-seg from @lorenzlamm.bsky.social et al., you might find my napari plugin "napari-segselect" useful. Let's say your tomogram contains the edges of two bacterial cells, each with a membrane and cell wall:
