Lighter, cheaper radio wave device could transform telecommunications
Researchers at the Cockrell School of Engineering at The University of Texas at Austin have achieved a milestone in modern wireless and cellular telecommunications, creating a radically smaller, more efficient ...
Interplanetary precision laser could reach to Mars and beyond
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 ...
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.
Finding hints of gravitational waves in the stars
Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be "seen" by looking at the stars. The new model proposes that ...
Researchers discover way to allow 80 percent of sound to pass through walls
Meta-transmitarray offers unprecedented control of light on subwavelength scales
Printable 'bionic' ear melds electronics and biology
Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can "hear" radio frequencies far beyond the range of normal human capability.
Swirling electrons in the whirlpool galaxy
The whirlpool galaxy Messier 51 (M51) is seen from a distance of approximately 30 million light years. This galaxy appears almost face-on and displays a beautiful system of spiral arms.
Team builds first integrated graphene digital circuit to function at gigahertz frequencies
Quantenna promises 10-gigabit Wi-Fi by next year
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.
A low-cost, finger-nail sized radar
European researchers have squeezed radar technology into a low-cost fingernail-sized chip package that promises to lead to a new range of distance and motion sensing applications. The novel device could have important uses ...
Super-massive black hole inflates giant bubble
Like symbiotic species, a galaxy and its central black hole lead intimately connected lives. The details of this relationship still pose many puzzles for astronomers. Some black holes actively accrete matter. ...
