Mitochondrial DNA has long been treated as a workhorse record of cellular history, but new research suggests it also hides a subtle and previously overlooked form of damage. By uncovering this cryptic ...

The Iñupiat people of Alaska have long said that bowhead whales live two human lifetimes. That oral knowledge turned out to ...

Cancer’s strongest gene switches push DNA into damaging overdrive, creating repeated breaks and repairs that may fuel tumor ...

DNA can be damaged by normal cellular processes as well as external factors such as UV radiation and chemicals. Such damage can lead to breaks in the DNA strand. If DNA damage is not properly repaired ...

Deep beneath the shifting sea ice of the Arctic Ocean, a massive marine mammal moves slowly through waters that remain near ...

New research from the Kind Group at the Hubrecht Institute sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human ...

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 ...

Researchers have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question. Researchers from the University of Birmingham have uncovered ...

Organisms like eukaryotes and prokaryotes have sophisticated mechanisms of DNA repair after damage. Failure of repairing the DNA damage is considered to be the cause of induction of cell death, ...
