How does fever work?

Our new Science paper shows how elevated body temperature can protect against severe influenza and that avian-origin viruses escape this defence.

This is likely one reason why bird flus and some pandemic influenzas can be so severe.🧵

Avian-origin influenza A viruses tolerate elevated pyrexic temperatures in mammals
Host body temperature can define a virus’s replicative profile—influenza A viruses (IAVs) adapted to 40° to 42°C in birds are less temperature sensitive in vitro compared with human isolates adapted t...

Tired of knowing what you are looking for in your tomograms?
Why not try bluesky-less Frosina's new self-supervised algorithm for semantic segmentation and particle picking for #teamtomo (includes a new denoiser without the need for odd/even tomos)

Code is on GitHub if you want to try it out

MISO: microfluidic protein isolation enables single-particle cryo-EM structure determination from a single cell colony.

Or from a single dish of HEK cell culture in the case of two membrane proteins.

Excited to share a new chapter of my scientific journey in Chris Russo's group — developing a way to freeze proteins faster than they diffuse, paving the way for cryo-EM without air–water interface damage.

This one is a bit of a departure from the usual and definitely a work in progress!

We found that by using ab initio reconstruction at very high res, in very small steps, we could crack some small structures that had eluded us - e.g. 39kDa iPKAc (EMPIAR-10252), below.
