As the holidays arrive, a group of researchers has identified the precise mechanisms by which binge drinking contributes to clogs in arteries that lead to heart attack and stroke.

Rescue robot exercise

A rescue robot exercise was recently held in which about three dozen robots were tested by developers and first responders in order to develop a standard suite of performance tests.

Reducing nervous system inflammation

Researchers at Georgetown University Medical Center have discovered a new way to limit inflammation caused by the activation of microglia - key immune cells in the brain.

Evolution of human opposable thumb

Scientists have discovered a gene enhancer, known as HACNS1, that may have contributed to the evolution of the uniquely opposable human thumb.

Extracting sugars from biomass

In a new paper, researchers have detailed some of the most fundamental processes involved in extracting sugars from biomass, the first step in producing ethanol by fermentation.

Stopping flagella movement

A new paper describes, for the first time, how the flagellum's rotations are stopped so that bacteria stop moving.

Transient binding proteins

Most of the functions performed by a cell are the result of interactions between proteins, which recognise their binding partner by affinity features localised on the protein surface.

Electrical discharge in the brain

After a stroke, even unaffected areas of the brain are at risk – depolarization waves arise at the edges of the dead tissue and spread through the adjacent areas of the brain. If these waves are repeated, more cells die.
