Scientists identify key decision-point at which cells with broken DNA repair themselves or die
When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis.

Proteins caught 'in action' in intact cells using new electron microscopy technique
Proteins are literally the movers and the shakers of the intracellular world. If DNA is the film director, then they are the actors. And much can be learned about cell function – and dysfunction – by watching proteins ...
