Neutron stars in the computer cloud

The combined computing power of 200,000 private PCs helps astronomers take an inventory of the Milky Way. The Einstein@Home project connects home and office PCs of volunteers from around the world to a global supercomputer. ...

Researchers capture wasted heat, use it to power devices

(Phys.org) —Imagine how much you could save on your electricity bill if you could use the excess heat your computer generates to actually power the machine. Researchers at the UCLA Henry Samueli School of Engineering and ...

World record silicon-based millimeter-wave power amplifiers

Two teams of DARPA performers have achieved world record power output levels using silicon-based technologies for millimeter-wave power amplifiers. RF power amplifiers are used in communications and sensor systems to boost ...

Auroras shine light on solar flares

(Phys.org) —Astrophysicists at the University of Glasgow are looking to the Northern and Southern Lights to expand our understanding of solar flares.

Quantum Stealth material designed to make target invisible

(Phys.org)—Scientists are exploring better methods of camouflage, a so-called scientific invisibility cloak, and news has spread fast about a Canadian company with substantial claims on how far they have come with camouflage ...

Monitor your energy use with 'simple' smart plugs

(Phys.org)—Glancing at one's daily consumption of energy would lead to usage that is more reasonable and less greedy. Such a challenge gave birth to eSMART. This EPFL spin-off is in the process of installing its system ...

A millimeter-scale, wirelessly powered cardiac device

A team of engineers at Stanford has demonstrated the feasibility of a super-small, implantable cardiac device that gets its power not from batteries, but from radio waves transmitted from outside the body. The implanted device ...
