In the neighborhood of 2Å. Sometimes I find a few in the better parts of a 2.3Å map.

My first impression is that the heterogeneity isn't going to be the biggest challenge. I'm already pulling my hair over symmetry and anisotropy. 🙃

I started looking at the compositional heterogeneity challenge (#CompHet), some very weird things in there. Curious to figure out […]

#CryoEM how do we feel about this instrument? We may be in the market and I want to know what people are currently using.

Niche-specific dermal macrophage loss promotes skin capillary ageing - Nature Capillary-associated macrophages are selectively lost over time, contributing to impaired vascular repair and reduced tissue perfusion in older mice.

When Macrophages Disappear, Skin Blood Vessels Age!
Check out our new study @nature.com that uncovers how the loss of capillary-associated macrophages with age blocks vessel repair and blood flow, revealing a new cellular trigger of tissue aging. #Aging #Immunology

We have an open post-doc position in my group to study mRNA cleavage and polyadenylation using biochemical reconstitution and cryoEM.

Please get in touch if you are interested in joining this amazing team! 🔬🧬🤩

Important to remember the theoretical size limit is based on assumptions and a model that may or may not be complete. It isn't some indisputable universal truth.

Excited to share our latest work with @simonbullock11.bsky.social! We looked at how diverse mRNAs get selected for subcellular localization and it turns out that a single protein can recognize different RNA elements using shared features that weren’t apparent before.
