New preprint alert!

Read about Manikomycin, a hidden antibiotic from Streptomyces rimosus that targets the ribosomal E site, revealing a novel MOA against MDR pathogens.
Even old strains have surprises.

Heading to #TranslationUK2025?

Come find me at Poster P002 – I’ll be showing how kasugamycin, edeine & GE81112 target different steps of 30S initiation complex formation 🧬

Let’s chat ribosomes, antibiotics & translation! @biochemsoc.bsky.social

🧬 Spoke at the 2nd Polish RNA Biology Meeting in Poznań!

Presented my PhD work on how kasugamycin, edeine & GE81112 disrupt distinct steps of 30S initiation complex formation using cryo-EM.

Grateful for the engaged crowd & vibrant discussions!

We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social!

Hey #TeamTomo,
Ever been in need of a tutorial about the fundamentals of cryo-electron tomography? From preprocessing raw frames to high-res subtomogram averaging?
That's why @florentwaltz.bsky.social and I made this website!

A colder frontier in cryo-EM 🧪🔬

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).
