An especially interesting article on engineered bacteria in the treatment of colon cancer today: Chun Loong Ho and colleagues engineered an E. coli strain to bind to colon cancer cells and constitutively secrete an enzyme that can turn dietary derived glucosinolates (from cruciferous vegetables) into cancer fighting isothiocynates. Mice exposed to carcinogens and fed both the engineered bacteria and broccoli developed fewer and smaller colorectal tumors than exposed mice who were fed 1) neither bacteria or brocoli, 2) only bacteria, or 3) only broccoli.  Engineered probiotics anyone?

Also : A cultured community developed from wastewater that can reduce the greenhouse gas N2O to N2 and help mitigate global warming; the majority of Daphnia microbiomes are not passed from parent to offspring but absorbed from the surrounding environment; and the impacts of CRISPR-Cas9 selection pressure on phage evolution.
