#USDA posted an analysis of the D1.1 #H5N1 #birdflu viruses that infected Nevada cows β€” the new spillover event. They spotted a mutation in the PB2 gene that is associated with mammalian adaptation. What's this mean? Dunno. But 2 spillovers means more could come. www.aphis.usda.gov/sites/defaul...

What are the genotypes promoting human colonization in S. aureus? Authors pooled >~7k genomes from >1500 ppl & looked at genomic variation to infer adaptation. Hits in metabolic genes (esp. nitrogen), QS, and antibiotic targets (incl. new resistance mutations). Cool!

We identified protein domains in LUCA (Last Universal Common Ancestor). Their distinctive amino acid usage reveals the order amino acids were added to the genetic code, based mostly on size. Older proteins hint at earlier alternative codes. 1/15 @seekingluca.bsky.social www.pnas.org/doi/10.1073/...
