Did you ever wonder about vitamin B12 role in microbiome organization and function? using a chemical probe mimic of vitamin B12, the authors reveal a light- and B12-dependent DNA regulator and predict that organismal interdependencies for B12 may be critical to microbiome stability and overall function.  On the extremophiles front, a study provides an analysis of the genomic content of the most abundant bacterial inhabitants of the salt-secreting desert tree Tamarix aphylla.  An interesting paper reinforced linkages between the colonization of the foodborne pathogen E. coli O157:H7 in cattle and the nature of the microbial community inhabiting the digestive tract of super-shedders. And as for future generations, if you want to get your kids or students excited about microbiology, try an interactive tool created by Stanford bioengineers: the 3D printed microscope powered by your smartphone.
