Scientists Say They've Just Reversed Aging in Human Cells

Skeptics call the therapy 'snake oil'

(Newser) - To err is human—our own cells do it all the time. But new research suggests that when it comes to aging, there may be a workaround. Scientists report in the Journal of the American College of Cardiology that they triggered cells to produce the protein telomerase, which lengthens the... More »

Mutant Genes Linked to Long Life

DNA-protecting enzyme may be key to living to 100

(Newser) - Scientists have spotted a link among people who live to age 100: high levels of telomerase, an enzyme that protects DNA and could possibly be simulated in life-lengthening drugs. The enzyme repairs telomeres, end sections of DNA that have been likened to plastic tips that prevent shoelaces from unraveling. In... More »
