RNA reactor could have served as a precursor of life

(PhysOrg.com) -- Nobody knows quite how life originated on Earth, but most scientists agree that living cells did not abruptly appear from nonliving cells in a single step. Instead, there were probably a series of pre-cellular ...

Study examines how DNA damage is repaired by antioxidant enzymes

A typical human cell is metabolically active, roaring with chemical reactions that convert nutrients into energy and useful products that sustain life. These reactions also create reactive oxygen species, dangerous by-products ...

Study gives insight into sun-induced DNA damage and cell repair

A team led by a Baylor University researcher has published a breakthrough article that provides a better understanding of the dynamic process by which sunlight-induced DNA damage is recognized by the molecular repair machinery ...

Scientists tie DNA repair to key cell signaling network

University of Texas Medical Branch at Galveston researchers have found a surprising connection between a key DNA-repair process and a cellular signaling network linked to aging, heart disease, cancer and other chronic conditions. ...

Mathematical analysis reveals architecture of the human genome

Mathematical analysis has led researchers in Japan to a formula that can describe the movement of DNA inside living human cells. Using these calculations, researchers may be able to reveal the 3D architecture of the human ...

DNA repair discovery could improve biotechnology

A team of researchers from Michigan State University's College of Veterinary Medicine has made a discovery that may have implications for therapeutic gene editing strategies, cancer diagnostics and therapies and other advancements ...
