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 ...

Being good at your job won't stop age discrimination

How old you are could be more important to some employers than your experience, or your capacity to do the job—particularly for older candidates. That was the conclusion of research my colleagues and I recently published ...

A material that 'bruises' like skin

Human skin bruises when the tissue and muscle in the area suffer trauma or become damaged due to the application of blunt force. However, when an object suffers an impact, it is necessary to examine every inch of the surface ...

Study reveals robust performance in aged detonator explosive

In a large, statistically significant, one-of-a-kind study, researchers at Los Alamos National Laboratory have confirmed that the explosive called PETN (Pentaerythritol tetranitrate), stabilized with a polysaccharide coating, ...

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 ...
