DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

New study shows that cancer damages its own DNA by pushing key genes to work too hard. Researchers found that the most powerful genetic "on switches" in cancer cells, called super-enhancers, drive ...

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

Walk into any drugstore and you'll see shelves stacked with bottles promising better health. Millions of people pop vitamins and supplements daily, convinced they're doing something good for their ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...

The tiny little powerhouses of our cells: mitochondria, are unique among organelles because they carry their own tiny little genomes. This genetic material is separate from the rest of our genomic DNA ...
