Following the path of radicals and being able to identify many damaged residues because of incredibly accurate, expeditious and sensitive mass spectrometry, three scientists studied the great granddaddy of all photosynthetic organisms -- a strain of cyanobacteria -- to develop the first experimental map of that organism's water world.

Humans have roughly as many bacterial cells in their bodies as human cells, and most of those bacteria live in the gut. New research released today reveals links between the gut microbiome -- the population of microorganisms living in the gastrointestinal tract -- and brain diseases such as Parkinson's and Alzheimer's, including potential new ways to track and treat these diseases.

Never-before-seen images of mouse immune system proteins and bacterial bits reveal an inspection strategy that identifies pathogens.

Stable autonomous kill switches ensure biocontainment of living microbes designed as devices for medicine or the environment. New research outlines two new types of kill switches that address these challenges. The new kill switches are self-sufficient and highly stable in bacterial populations that evolve, and they last over many generations. They can ensure that only bacteria with intact synthetic gene circuits survive, or confine bacteria to a target environment at 37°C (body temperature) while inducing them to die at lower temperatures, as demonstrated during bacterial exit from a mouse intestinal tract.

A leaf-eating beetle has evolved a symbiotic relationship that allows the insect to break down pectin. The findings on the novel function of the bacterium, which has a surprisingly tiny genome -- much smaller than previous reports on the minimum size required for an organism not subsisting within a host cell.
