Scientists are experimenting with bacteria to see if evolution plays out the same way every time.

Investigating the genetic books of life reveals new details of 'descent with modification' and the forces driving it. (p. 26)

The first complete mitochondrial genome of the Tasmanian tiger is revealed. Analysis shows little genetic diversity.

An antibiotic produced by a bacterium acts as a molecular snorkel to help with breathing. The bacterium infects and kills many people with cystic fibrosis, and plugging the snorkel could lead to treatments. (p. 8)

Imaging study reveals variation in brain activity depending on the severity of punishment a person decides.
