A groundbreaking new study from Bar-Ilan University shows that one of sleep's core functions originated hundreds of millions ...

In jellyfish and sea anemones, neurons accumulate DNA damage while animals are awake and repair that damage during sleep.

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 ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

Cedars-Sinai scientists have developed an experimental drug that repairs DNA and serves as a prototype for a new class of medications that fix tissue damage caused by heart attack, inflammatory ...
