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

Cancer cells respond to stress with greater diversity. Drugs that affect DNA replication, or radiation that causes direct DNA damage, lead to increasingly diverse offspring over multiple cell ...

RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team has now gained new insights into the DNA damage response. Whenever cells ...

Collaborative research from the Massachusetts Institute for Technology in Cambridge and the National University of Singapore suggests asthma- and allergy-causing dust mites induce DNA damage in lung ...

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 ...

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...

As people grow older, their immune systems do not simply slow down, they often become locked into a simmering, ...

(Beyond Pesticides, May 29, 2025) A study, published in Environmental Toxicology and Pharmacology, “investigates genotoxic effects on farmers in Paraíba, Brazil, analyzing buccal mucosa cells [cells ...
