This microbe can survive doses of radiation that would obliterate any other living thing. Here’s what this means for science ...

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

Study finds CRISPR/Cas gene editing causes “chromatin fatigue” – another surprise mechanism by which it can produce unwanted ...

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both sides of the DNA helix are cut at once. Healthy cells can normally fix ...

Researchers found that losing a second protein, FIGNL1, allows cancer cells missing BRCA2 to restore DNA repair by reloading RAD51 onto broken DNA strands. Normally, BRCA2 helps place RAD51 at DNA ...

The bowhead whale’s remarkable lifespan and low cancer risk stem from a finely tuned DNA repair system driven by a unique protein, CIRBP. Scientists found that this mechanism not only preserves the ...

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...

Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...
