🚀 Check out our new preprint on extending the scope of single-particle cryo-EM with 2D template matching! Improved cryo-EM reconstruction of sub-50 kDa complexes using 2D template matching is now available on bioRxiv! www.biorxiv.org/content/10.1...

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. Read on for details... 1/x

Right now, the continuation of many restored NIH grants relies on the SCOTUS shadow docket. SCOTUS is not immune to pressure. Also, if you are represented by one of the 14 R senators that called for the restoration of NIH grants, please write them a thank you. Good behavior should be rewarded.

Submit your method to our denoising challenge!!! 👍

Cutler & Glaser in JAMA: The proposed budgetary cuts to NIH will create a social cost 16 times greater than the savings the administration is attempting to achieve. The Trump administration should recognize that funding science is good economic as well as health policy.

Meeting of the four #cryoET centers (funded by the NIH Common Fund), in beautiful Boulder! great exchange of ideas and totally nerding it out over all things cryoET. Great to hear from users from all across the country and their impressive science. #NIH at its best.

Huge congratulations to @hbelda.bsky.social and David Bradley for their publication on the extraordinarily interesting FIKK kinase family (I am biased) of the malaria causing parasite Plasmodium falciparum. 1/n

We are looking to hire (yes, even in this economy!) a jr. specialist to train in protein prep/structural biology related to our AVOID-ome work as part of openadmet.org. A great position for someone who is looking to be a tech for a few years before grad or med school. aprecruit.ucsf.edu/JPF05424

Parasites need mitochondrial respiration to infect and spread. Effective anti-malaria and ani-toxoplasmosis drugs target respiratory complexes (e.g. atovaquone)! But how do the parasite complexes work and how do drugs inhibit them? Read Andrew Maclean and Alex Mühleip phenomenal work on this! 👇

Superb and important article, pointing out that politically the best way to save biomedical research is to get communities around different diseases informed of the problem, and set them loose on their congresspeople. Right now they just don't know what's going on. How to make this happen?
