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.

A brief, intense workout may do more than boost fitness—it could help fight cancer. Researchers found that just 10 minutes of ...

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, ...

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 ...

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 ...

Greenland sharks possess a DNA repair mechanism that maintains vision over centuries, preventing retinal degeneration despite ...

Bar-Ilan University study shows that even jellyfish and sea anemones repair DNA during repose, underscoring the idea that a ...
