A switch to control the spin current

Researchers at Tohoku University in Japan have discovered a switch to control the spin current, a mechanism needed for information processing with full spin-based devices.

Switching gears toward efficient datacenters with photonics

How can we scale-up datacenters in such a way that they can handle more data at lower cost, while consuming less energy? At Eindhoven University of Technology, Ph.D. student Gonzalo Guelbenzu developed strategies to process ...

'Negative capacitance' could bring more efficient transistors

Researchers have experimentally demonstrated how to harness a property called negative capacitance for a new type of transistor that could reduce power consumption, validating a theory proposed in 2008 by a team at Purdue ...

Improving cyber security in harsh environments

Many people don't worry about the security of their personal information until it's too late. And protecting data is even more important for military personnel, whose lives could be in danger if some types of information ...
