The secret to longevity? Ask a yellow-bellied marmot

That's what a team of UCLA biologists and colleagues studying yellow-bellied marmots discovered. These large ground squirrels are able to virtually halt the aging process during the seven to eight months they spend hibernating ...

Glass as stable as crystal: Homogeneity leads to stability

Scientists from The University of Tokyo Institute of Industrial Science used computer simulations to study the aging mechanism that can cause an amorphous glassy material to turn into a crystal. They find that removing tiny ...

A new non-invasive technique for parchment diagnosis

The conservation state of parchments is typically assessed using invasive and sometimes destructive investigation techniques. Scientists from Université Paris-Saclay, the CNRS, École Polytechnique, and the French Ministry ...

Scientists may need to rethink which genes control aging

To better understand the role of bacteria in health and disease, National Institutes of Health researchers fed fruit flies antibiotics and monitored the lifetime activity of hundreds of genes that scientists have traditionally ...

Light flips genetic switch in bacteria inside transparent worms

Researchers from Rice University and Baylor College of Medicine have shown that colored light can both activate and deactivate genes of gut bacteria in the intestines of worms. The research shows how optogenetic technology ...

Simulations open a new way to reverse cell aging

Research findings by a KAIST team provide insight into the complex mechanism of cellular senescence and present a potential therapeutic strategy for reducing age-related diseases associated with the accumulation of senescent ...

Your cells look young for their age, compared to a chimp's

Many humans live to see their 70s and 80s, some even reach 100 years old. But life is much shorter for our closest animal relatives. Chimpanzees, for example, rarely make it past age 50, despite sharing almost 99% of our ...
