Scientists Identify Signature of Aging in the Brain

September 29, 2014 1:14 pm | News | Comments

How the brain ages is still largely an open question– in part because this organ is mostly insulated from direct contact with other systems in the body, including the blood and immune systems. Now, new research may have found evidence of a unique “signature” that may be the “missing link” between cognitive decline and aging.

Stem Cells Help Study How Mutation Affects Heart Health

September 26, 2014 8:30 am | News | Comments

Over 500 million people worldwide carry a genetic mutation that disables a common metabolic protein called ALDH2. The mutation, which predominantly occurs in people of East Asian descent, leads to an increased risk of heart disease and poorer outcomes after a heart attack.
