Here are few interesting articles for your Sunday morning edition. Canadian bacteria-like fossils may be the oldest evidence of life yet.  Black carbon, one of the main components of air pollution,  is reported to drastically change the development of bacterial biofilms and key aspects of bacterial colonization and survival.  A novel organ culture system described for the mouse intestine shows that the nervous system influences the microbiome/immune system crosstalk.  And the power of alternative assays for discovery: Deep sequencing of cell-free DNA from a large patient cohort revealed previously unknown and highly prevalent microbial and viral diversity in humans.
