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

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 ...

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

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 ...

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

A protein found in bowhead whales, one of the longest-living mammals on Earth, could help improve how human cells repair DNA, according to new research from scientists at the Albert Einstein College ...

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 ...

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, ...

An international research team from the University of Oxford and Nanyang Technological University (NTU Singapore) reports the discovery of a new process for repairing damaged DNA that is particularly ...
