A mathematical model from statistical physics can help reveal properties of populations under changing immune selection (changing fitness landscapes/seascapes).

Interesting paper www.nature.com/articles/s41... it seems to be consistent with recent spillover event(s) discovered in a dairy farm in the northern Netherlands, but would be interesting to see how many of those potentially mammal adaptive mutations in this wave of bird migration?

Well, that's almost every postdoc's daily life in Oxford or Cambridge. On the positive side, some of the research directions you pursue can be intellectually satisfactory and beneficial to your career even if they did not make it to one of these journals.

Bird flu antibodies found in cow in the Netherlands, a first outside of U.S. Dead cat led to discovery, but officials stress no further spread of H5N1 has been detected

This first probable case of highly pathogenic avian influenza in a dairy cow in Europe raises two points. First, it suggests that virus incursion is possible in the Dutch housing system, which differs from that in the southern U.S., where cows were first infectted. www.science.org/content/arti...

I guess it wont work well is because many genes and their carriers/genomes evolve in a way determined by non-fixed population genetic parameters, and current data do not cover their changing evolutionary landscapes spanning vast biological complexity. www.biorxiv.org/content/10.6...

One comment I like is that many of the "working" methods are like "cooking recipes", and you also need diversity for future success in this field.

Gene copy-number features generalize better than SNPs for antimicrobial resistance prediction in Staphylococcus aureus - npj Antimicrobials and Resistance npj Antimicrobials and Resistance - Gene copy-number features generalize better than SNPs for antimicrobial resistance prediction in Staphylococcus aureus

Generally bacteria can have large effective population size, and there are less genetic redundancy due to effective selection, so gene copy number can be very useful in certain context for predictive modelling.

Absolutely stoked to have this published in @plosbiology.org

We looked at the metabolism of #Klebsiella pneumoniae 🦠🧫. We not only demonstrated lineage-specific #metabolism, but that lineages can cross-feed and support each other.
