Do-it-yourself invisibility with 3-D printing
Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.
New circuit design allows for elimination of laptop charger brick
Generating broadband terahertz radiation from a microplasma in air
Researchers at the University of Rochester's Institute of Optics have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation.
Can you drive fast enough to avoid being clocked by speed cameras?
Anyone wanting to avoid being caught out by speed cameras can do so very simply - by obeying the speed limits.
Detected radio bursts evidence of 'exotic phenomena'
The detection of four short bursts of radio waves, possibly arising from explosions billions of light years away, could be powerful tools to study our Universe, according to research published in Science.
DARPA circuit achieves speeds of 1 trillion cycles per second, earns Guinness world record
Officials from Guinness World Records today recognized DARPA's Terahertz Electronics program for creating the fastest solid-state amplifier integrated circuit ever measured. The ten-stage common-source amplifier ...
