In today’s digest we have many interesting articles, particularly in “General Microbiome” section. Check a review on integrative view of cell cycle control in E. coli by L. Dewachter, an article on the return of cultures in microbiology by V. Marx, an article on microbial altruism and cheating in social amoebas by S. Noh. Don’t miss great articles from other sections, like “Water microbiome” where I would recommend an article deciphering the evolution and metabolism of an anammox bacterium by M. Strous and an article about globally overlooked nanoplanktonic diatoms by K. Leblanc. Happy reading!
