Women in their 60s and 70s could theoretically one day give birth to genetically related children, according to scientists pioneering a breakthrough technique that converts DNA from skin cells into ...

A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

A bacterial defense system called SPARDA employs kamikaze-like tactics to protect cells and could be useful in future ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

A trio of mRNA molecules could help guard against the harmful effects of aging on immune cells, a study in mice finds. A new ...

Stanford University-led researchers report that tumor cells hijack mitochondria from immune cells, reducing anti-tumor immune ...

Randomness inside cells can decide whether a cancer returns after chemotherapy or whether an infection survives antibiotics.

Biology has always been an unruly science. Cells divide when they want to. Genes switch on and off like temperamental lights.

What if a single Renaissance drawing could reveal not just who made it, but the biological traces of Leonardo da Vinci ...
