Labs around the world are trying to turn cells into autobiographers, tracking their own development from embryos to adults. By Carl Zimmer Shortly after conception, a fertilized egg divides, becoming ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

Scientists have succeeded in controlling the structure and function of biological membranes with the help of 'DNA origami'. The system they developed may facilitate the transportation of large ...
