Thousands of people are jetting off for a week of sun, snow, and après-ski. And while they may worry about breaking limbs, how many consider the dangers of skin cancer?

The research focused on signaling pathways that mediate an anti-tumor defense response called senescence, or cellular aging. The research, which was conducted in both human cell culture and rodent models with skin cancer or lymphoma, identified one essential element of this anti-tumor response, namely, p38-regulated/activated protein kinase (PRAK). Previous to this research, PRAK's physiological functions had been poorly understood.

Substances extracted from a marine seaweed may protect against skin cancer caused by too much sun, new research suggests.
