Protein primes mouse stem cells to quickly repair injury

Pretreatment with a stem-cell-activating protein significantly enhances healing in mice, Stanford researchers say. The approach could eventually help people going into surgery or combat heal better from injuries they sustain. Full article

Scientists Say the Clock of Aging May Be Reversible

At the Salk Institute in La Jolla, Calif., scientists are trying to get time to run backward. Biological time, that is. In the first attempt to reverse aging by reprogramming the genome, they have rejuvenated the organs of mice and lengthened their life spans by 30 percent. The technique, which requires genetic engineering, cannot be […]
