DNA Nanorobots Pick Up And Sort Molecules

An autonomous molecular machine, made of a single strand of DNA, that can autonomously “walk” around a surface, pick up certain molecules and drop them off in designated locations has been developed by scientists at California Institute of Technology. Lulu Qian, assistant professor of bioengineering, explains: “Just like electromechanical robots are sent off to faraway [...]

How DNA Defends Itself Against Ultraviolet Light

The ultrafast response of DNA nucleobases to ultraviolet light has been measured, using X-rays from the Linac Coherent Light Source. The UV excited state in the nucleobase thymine decays rapidly, researchers found, harmlessly dissipating the potentially destructive UV energy. This experimental research sheds new light on how the nucleobases inside DNA protect themselves from damage [...]
