(Nanowerk News) If you could peek at the inner workings of a computer processor you would see billions of transistors switching back and forth between two states. In optical communications, ...

Towards ultrafast logic gates (Courtesy: University of Rochester illustration / Michael Osadciw) The first logic gate to operate at femtosecond timescales could help usher in an era of information ...

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of ...

Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...

(a)Working principle of the spin logic device. (b) Transition among diverse magnetic configurations in this heterojunction. By manipulating the direction of the Oersted field, the SOT-induced ...

In recent years, researchers in the messy world of biology have been able to build systems that function like the clean, binary switches on computer chips—and we've covered a number of reports in this ...

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...

Computers use electrical circuits which have two states – on or off. This can also be represented as 1 or 0 or True and False. Logic gates take an input of True or False and give an output of True or ...

[Jacob Christ] writes in with a hack that’s going to be this summer’s fidget spinner. Why? The favourite toy of his youngster’s generation is a Glimmie. And while fidget spinners were useful for, well ...
