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

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

Greenland sharks use a unique DNA repair process to protect their eyesight, revealing clues about longevity and retinal preservation.

Scientists have discovered a protein that can directly halt DNA damage. Better yet, a new study shows it appears to be 'plug and play', theoretically able to slot into any organism, making it a ...

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren't just skin deep. Inside the body, DNA is literally being torn ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

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 ...

A team of researchers led by Stanford University and San Diego-based Boundless Bio have identified an oral small molecule that specifically targets extrachromosomal DNA (ecDNA) in cancer cells, ...
