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 ...

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

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, ...

Learn how jellyfish and sea anemones are changing what we know about the evolutionary purpose of sleep.

Just 10 minutes of exercise each day can halt bowel cancer growth and speed up DNA damage repair, a study has found.

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 ...

The study looked at blood samples from 30 overweight adults taken before and immediately after a max-effort cycling workout, which lasted about 10 to 12 minutes. They then exposed human colon cancer ...

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 ...
