Exclusive: Medical journal rejects Kennedy's call for retraction of vaccine study An influential U.S. medical journal is rejecting a call from Health Secretary Robert F. Kennedy Jr. to retract a large Danish study that found that aluminum ingredients in vaccines do not increase health risks for children, the journal's editor told Reuters.

I am #exhilarated to share that our new paper "LIGYSIS-web: a resource for the analysis of protein-ligand binding sites" is now published in @narjournal.bsky.social! After almost two years of development and more than 600 commits, LIGYSIS-web is out!

We have benchmarked the AF2 multimer on coiled-coil domains and the results are also very good (even outperforming dedicated tools). Interestingly, the performance does not depend on the use of MSA: onlinelibrary.wiley.com/doi/full/10.....

This chopped alignment does not look meaningful. Or do I miss something?

Coiled coils (CCs) are protein domains in which alpha helices assemble into regular supercoiled bundles. In our new paper, we investigate how accurately AlphaFold2 predicts the oligomeric state, topology, and fine structural details of CC domains: onlinelibrary.wiley.com/doi/10.1002/....

Large livestock facilities in states across the country have become epicenters of bird flu, and some researchers say that’s no surprise:

Putting thousands of animals together in confined, cramped barns or corrals creates a petri dish for virus to spread, according to WIRED.

Maybe “Logicomix: An epic search for truth”?

The science behind winning a Nobel Prize? Being a man from a wealthy family | Torsten Bell A lot of talent is wasted in a world where more than half of laureates come from households in the richest 5%

If talent and opportunity were equally distributed, the average #NobelPrize winner would come from a middle income background.

The reality? The average laureate grew up in a household just below the top 10%. More than 50% come from the top 5%.

I have a PhD position available in my group, to start in March 2025. If you have a keen interest in biochemistry and would like to study an exciting and novel class of copper proteins (aka weird Cu tubes) from bacteria, I'd love to hear from you.

Applicability of AlphaFold2 in the modeling of dimeric, trimeric, and tetrameric coiled-coil domains Coiled coils are a common protein structural motif involved in cellular functions ranging from mediating protein-protein interactions to facilitating processes such as signal transduction or regulatio...

We’ve seen such cases among coiled-coil domains. Fig. 8 here www.biorxiv.org/content/10.1...

Related to that, there is a fun PPI prediction challenge by @chembiobryan.bsky.social, which I'd like to advertise to everyone developing PPI prediction models. Tests like that are crucial for assessing model generalization capabilities!

Not only is this an illusion, but it is a western culture-oriented illusion.

Left, cry-EM structure of the complex between MIK2 (green), the immunoregulatory peptide SCOOP (yellow) and the LRR of the co-receptor BAK1 (white) with only the most rigid part of the N-glycans resolved (1 or 2 or none) and represented with sticks. Right, reconstruction of the N-glycosylation with plant N-glycans G90477LS,selected to be all the same as glycoproteomics data is not available (as far as I know)

If you are interested or working in #structuralbiology, as you see any protein (yes, *any*), you should be thinking: is it glycosylated? The answer is likely to be yes! You can predict N-glycosylation sites and rebuild all types of glycans with ReGlyco glycoshape.org 😌
