Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate ...

We are exposed to ionizing radiation more often than we think: when we bathe in the sun, which emits UV rays, or when we get X-rayed. Even when we are travelling on an intercontinental flight, which ...

An elegant collaboration between researchers in the UK's two core-funded Medical Research Council Research Institutes, the Laboratory of Medical Sciences (LMS) in London and the Laboratory of ...

What scientists long believed were knots in DNA may actually be persistent twists formed during nanopore analysis, revealing ...

As people grow older, their immune systems do not simply slow down, they often become locked into a simmering, ...

( NewsNation) — Tanning beds cause melanoma -linked DNA damage across nearly the entire surface of the skin, a new study found. The precise biological process behind the increased risk of melanoma ...

Many people lather up with sunscreen or cover up with hats to protect themselves from the sun’s harmful rays. These added layers help to shield the skin from ultraviolet (UV) light, which damages DNA ...

A team of scientists at the University of Seville has identified an essential process that protects DNA integrity in reproductive cells, providing new clues about how organisms avoid genetic defects ...
