Circulating tumor DNA (ctDNA) is a blood test that looks for tiny pieces of cancer DNA released by dying cells, allowing doctors to detect cancer using a simple blood sample, Dr. Nicholas Hornstein ...

Scientists have found that twisting structures in DNA long mistaken for knots are actually something else entirely. Inside cells, DNA gets twisted, copied, and pulled apart. The twists can influence ...
