If I could ask all #cryoEM samples for one thing, it’d be to *please* behave like 1um TetraSpecks.

Since it was published at peak holiday season, I'm taking the liberty to re-introduce our recent review article. We hope it will be a useful overview of RNA virus replication strategies, and how in situ cryo-EM have helped us understand them:

Viral proteins typically exist in the context of complex virions or in the even more complex host cells in which they replicate. Hence, meaningful ins…

Ever wondered how to position organelles in bacteria? Wonder no more!
Happy to have contributed to this fantastic story from @cellforganized.bsky.social' lab.

The avenues this opens in the synthetic biology space are enormous!

A productive morning with Profs. Dötsch, García-Sáez and Helfrich! We learnt about transcription factors, cellular death and biosynthetic pathways. All before lunch time! #sciencemorning #gradschool @mpibp.bsky.social @goetheuni.bsky.social

At what number of hidden layers do shallow learning networks cross over to being deep learning? One? More? Depends?🤔

Sonja Welsch @sonjawelsch.bsky.social · 22d

I’d also throw “general problem solving skills” in the mix - and requirements for being good at problem solving might indeed change over time (as the nature of open questions tends to shift over time)?

Our aim was to create a kit to produce in-house 1.2 holey carbon cryoEM grids, in three simple steps, at less than half of the prize, and without due times. I think we are there. Academic teams that want to know more, receive training or order a kit, please contact [email protected].

Attending a mandatory radiation safety refresher course today (because where I am: no #cryoEM without certified radiation safety officer) and - right on cue - this came up 😶

Deryck Mills is always missed dearly @mpibp.bsky.social, but some weeks his absence is more obvious than others. Just bought a new 30um aperture. Opened the bottom drawer of Deryck’s trolley days later - and found this 🤩

Amazing collection of TEM apertures, some dating back to the 1990’s.
