1/3: We are excited to share a new study by Maarten Tuijtel from @becklab.bsky.social, published in eLife. 🔬 🎉 The work addresses a key question in cryo-electron tomography: how to best distribute the limited electron dose across a tilt series while balancing angular sampling and image quality. 💥

Cryo-EM images showing sample structures at tilt increments from 1 to 10 degrees, with resolution patterns and measured values in nanometers.

Microscopy nerd alert: two scopes in California can now do phase contrast cryoEM - potentially fixing the tech's very low signal/noise ratio. The phase filter they used is a laser. Which is also the brightest thing in the solar system (outside of the inside of the sun). cen.acs.org/analytical-c...

Exciting to see momentum building around our concept of inverse agonist-bound GPCR–G protein complex structures (PMID: 39775170). Great work from the groups of Can Cao & Xiaoguang Lei: a clinically viable MRGPRX4 inverse agonist for chronic itch with therapeutic potential. Congrats to all!
