Study ties aging to oxidative damage in mitochondria

As long as humans have been alive, they've been seeking ways to extend life just a little longer. So far no one has found the fountain of youth, but researchers have begun to understand how humans age, little by little, offering ...

Complex interactions may matter most for longevity

If studying a single gene or a diet that might extend longevity is like searching for a fountain of youth, then a new study calls for looking at something more like the whole watershed. Brown University biologists who experimentally ...

New advances in the study of human mitochondrial DNA

A study concerning the evolution of mitochondrial DNA, performed by researchers from the Universitat Autònoma de Barcelona (UAB), has allowed to determine the frequency and pattern of heteroplasmy in the complete mitochondrial ...

Scientists create one-step gene test for mitochondrial diseases

More powerful gene-sequencing tools have increasingly been uncovering disease secrets in DNA within the cell nucleus. Now a research team is expanding those rapid next-generation sequencing tests to analyze a separate source ...
