Gene Manipulation Extends Mice Lives

By 20 percent.

Listen up, Sergey Brin. By tweaking the activity of a certain type of gene, scientists say they have found a way to extend the lifespan of mice by 20 percent—that’s about 15 years for humans. Not only was time added, but also quality of life was affected positively by the 25 percent reduction in levels of mTOR protein. Researchers say people shouldn’t start planning their 100th birthday parties just yet, but claim their work could eventually be a part of the strategy for lengthening human lives. And it wasn’t all good news. The longer-living mice also got softer bones, more infections, and possibly a higher risk of cataracts.
