The World's Oldest Living People are the Same Despite Extreme Longevity

It turns out that having good or bad genes actually doesn't influence whether you'll live longer or not. Using fewer than 20 genes, scientists were unable to find rare protein-altering variants that were significantly associated with extreme longevity.

The Secrets of Longevity: Torpor in Hibernation May Slow Aging

As temperatures cool and then dip below freezing, some animals hurry to store enough fat to last through the winter as they hibernate. Now, scientists have taken a closer look at hibernation and have found a link between time spent at higher temperatures and aging.

Scientists Discover 'Signature Of Aging' In The Brain

Though scientists are still working to determine just how the brain ages, new research illustrates evidence that the organ's immune interaction occurs across a barrier that is actually a unique interface within the brain's territory.
