MIT engineers have developed a novel method to assemble arrays of quantum rods, which could be integrated into LEDs to enhance televisions or virtual reality (VR) devices. MIT engineers devised a new ...

Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment has been the focus of a 30-year research question. New work from the Crick ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

MIT engineers have used DNA origami scaffolds to create precisely structured arrays of quantum rods, which could be incorporated into LEDs for televisions or virtual reality devices. Credit must be ...

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 ...
