The tiny little powerhouses of our cells, the mitochondria, are unique among organelles because they carry their own tiny ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

Researchers at The Institute of Cancer Research, London identified the CIP2A–TOPBP1 complex as a master regulator of DNA repair during mitosis, coordinating backup pathways that protect chromosomes ...

Newcastle University researchers discover exercise rapidly alters blood chemistry to support DNA repair in colon cancer cells ...

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 ...

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, ...

Humans began sleeping as a way to partly help reduce DNA damage in nerve cells, scientists at Bar-Ilan University in Israel ...

Jellyfish and anemones sleep to repair neuronal DNA damage Jellyfish and sea anemones extend sleep when neuronal DNA is ...

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 ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

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