DNA 'origami' could help build faster, cheaper computer chips

Electronics manufacturers constantly hunt for ways to make faster, cheaper computer chips, often by cutting production costs or by shrinking component sizes. Now, researchers report that DNA, the genetic material of life, might help accomplish this goal when it is formed into specific shapes through a process reminiscent of the ancient art of paper folding.

A nanoparticle does double duty, imaging and treating atherosclerosis

Scientists have developed a nanoparticle that functionally mimics nature's own high-density lipoprotein (HDL). The nanoparticle can simultaneously light up and treat atherosclerotic plaques that clog arteries.

Nanomotors could help electronics fix themselves

As electronics grow ever more intricate, so must the tools required to fix them. Anticipating this challenge, scientists turned to the body's immune system for inspiration and have now built self-propelled nanomotors that can seek out and repair tiny scratches to electronic systems.
