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 ...

Cancer genomes are the result of diverse mutation processes that have often accumulated over decades. Scientists have analyzed the molecular evolution of tumors after exposure to mutagenic chemicals.

Ultraviolet (UV) rays from sunlight can cause DNA damage that leads to skin aging and cancer. Fortunately, our bodies have a highly efficient repair system capable of swiftly identifying and repairing ...

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

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Microscopic tardigrades have fascinated scientists for their ...

A protein found in our cells has emerged as a secret weapon against biological aging, acting like a glue to repair damaged DNA and ward off neurological degeneration including that seen in motor ...

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 ...

Cancer genomes are the result of diverse mutation processes that have often accumulated over decades. Scientists from the German Cancer Research Center (DKFZ) and the Universities of Cambridge and ...

The Summit supercomputer revealed how damaged strands of DNA are surgically repaired by a molecular pathway called nucleotide excision repair, or NER. NER’s protein components can change shape to ...

Tardigrades were first discovered in the Eighteenth Century and are known to survive in some of Earth’s most inhospitable environments. “What we saw surprised us,” study co-author and University of ...
