In today’s digest read about the selection and microdiversity in glacier-fed streams, Gardnerella vaginalis contribution to the increased rate of group B Streptococcus vaginal colonization, making F1 hybrids in Escherichia coli using MAE (Mass Allelic Exchange), smORFinder (annotation tool to identify small proteins in microbial genomes and metagenomes), and more.
Check out the new Science Friday podcast episode on microbial interactions in cheese rinds and Svetlana’s pick for happy holidays.
Cheers!
