Fast, rewritable computing with DNA origami registers

DNA stores the instructions for life and, along with enzymes and other molecules, computes everything from hair color to risk of developing diseases. Harnessing that prowess and immense storage capacity could lead to DNA-based computers that are faster and smaller than today's silicon-based versions. As a step toward that goal, researchers report a fast, sequential DNA computing method that is also rewritable -- just like current computers.

Physics: Current generated by the quantum Hall effect has additional magnetic properties

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises fr...
