Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division—a discovery that could lead to new cancer therapies, according to ...

In a remarkable turn of events, scientists have stumbled upon non-human DNA from ancient fossils, shaking the very foundations of our understanding of human evolution and our ancestral lineage.

Scientists have uncovered a surprising twist in how cells behave when division goes wrong. Sometimes a cell successfully copies its DNA but fails to split into two, leaving it with double the genetic ...
