Toward more efficient computing, with magnetic waves

by Rob Matheson, MIT News

Circuit design offers a path to “spintronic” devices that use little electricity and generate practically no heat.

MIT researchers have devised a novel circuit design that enables precise control of computing with magnetic waves — with no electricity needed. The advance takes a step toward practical magnetic-based devices, which have the potential to compute far more efficiently than electronics.

How a computer sees history after “reading” 35 million news stories

by Eric Mack, New Atlas

So far, humans have relied on the written word to record what we know as history. When artificial intelligence researchers ran billions of those words from decades of news coverage through an automated analysis, however, even more patterns and insights were revealed.

Computers made of genetic material?

Researchers conduct electricity using DNA-based nano-wires

Tinier than the AIDS virus — that is currently the circumference of the smallest transistors. The industry has shrunk the central elements of their computer chips to fourteen nano-meters in the last sixty years. Conventional methods, however, are hitting physical boundaries. Researchers around the world are looking for alternatives. One method could be the self-organization of complex components from molecules and atoms.

Artificial atoms shed light on the future of security

by Joint Quantum Institute

From credit card numbers to bank account information, we transmit sensitive digital information over the internet every day. Since the 1990s, though, researchers have known that quantum computers threaten to disrupt the security of these transactions.

That’s because quantum physics predicts that these computers could do some calculations far faster than their conventional counterparts. This would let a quantum computer crack a common internet security system called public key cryptography. Continue reading Artificial atoms shed light on the future of security
