Study finds women’s breast tissue ages faster than the rest of the body

Everyone grows older, but scientists don’t really understand why. Now a UCLA study has uncovered a biological clock embedded in our genomes that may shed light on why our bodies age and how we can slow the process.

Published in the Oct. 21 edition of the journal Genome Biology, the findings could offer valuable insights to benefit cancer and stem cell research. (more…)

Muscle Cell Grafts Keep Broken Hearts from Breaking Rhythm

Researchers have made a major advance in efforts to regenerate damaged hearts. They discovered that transplanted heart muscle cells, grown from stem cells, electrically couple and beat in sync with the heart’s own mucle.

The grafts also reduced the incidence of arrhythmias (irregular heart rhythms) in a guinea pig model of myocardial infarction (commonly known as a heart attack).

This finding from University of Washington-led research is reported in the Aug. 5 issue of Nature. (more…)
