Today’s digest has quite a few reviews in “Human Gut Microbiome” section and quite interesting news: what killed Aztecs, the womb might not be sterile, while surfers might be spreading antibiotic-resistant bacteria. Check as well an interesting blog post on “How can academia kick its addiction to the impact factor?” and news about “Dimensions” – new science search engine. Dimensions not only indexes papers and their citations, but also – uniquely among scholarly databases – connects publications to their related grants, funding agencies, patents and clinical trials.

Interesting review to highlight is from L. Tipton about lung mycobiome  and the one from D. Rose Ewald about human microbiota. Today we also have quite few articles about viruses, among which P.C. Hsu revails gene targets of Ebola virus microRNAs involved in the human skin microbiome,  S. S. Jagdale reports on  mutualistic interactions of viruses with lower eukaryotes and C. Winter explains how mixing alters the lytic activity of viruses in the dark ocean.
