Bacteria uses viral weapon against other bacteria

Bacterial cells use both a virus—traditionally thought to be an enemy—and a prehistoric viral protein to kill other bacteria that competes with it for food according to an international team of researchers who believe ...

Scientists crack the code to regenerate plant tissues

Plant regeneration can occur via formation of a mass of pluripotent cells. The process of acquisition of pluripotency involves silencing of genes to remove original tissue memory and priming for activation by external input. ...

New electron microscopy technique limits membrane destruction

Membrane proteins play an important role in many biological processes. Studies suggest they're targeted by more than 50% of all modern medicinal drugs. Unfortunately for researchers, determining their structures has been ...
