A protein long studied for its role in amyotrophic lateral sclerosis and frontotemporal dementia now appears to serve a second, equally critical function, safeguarding the integrity of human DNA.

A new fluorescent sensor is giving scientists an unprecedented view of how cells respond to DNA damage, capturing the repair process as it unfolds in real time. The tool, developed at Utrecht ...

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

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 ...

A protein tied to ALS and dementia may have a much bigger role in disease than scientists realized. Researchers found that ...
