Graphene-based Nanoantennas Could Speed Up Wireless Networks
19 Dec | IEEE SpectrumFull Text External Link Indicator
"Researchers at the Georgia Institute of Technology say they've demonstrated via computer modeling that nano-antennas made from graphene could enable networks of nanomachines." Dexter Johnson

How to Harness the Power of 70,000 Suns

"Stacked solar cells are already the most efficient solar cells available, but researchers at North Carolina State University have found a technique to boost the cells' effectiveness even further." Katherine Tweed
Telescopic Contact Lens Could Improve Eyesight for the Visually Impaired
09 Aug | UCSD Jacobs School of EngineeringFull Text External Link Indicator
"San Diego, Calif., July 9 -- A team of engineers has designed a telescopic contact lens that can switch between normal and magnified vision by using slightly modified off-the-shelf 3D television glasses. The researchers, led by Joseph Ford, a professor of electrical engineering at the University of California, San Diego, built a prototype of the lens and tested it on a mechanical eye. Researchers report their findings in the June 27 online issue of Optics Express, an open-access journal of the Optical Society."
Uncertainty over the Uncertainty Principle
02 Aug | IEEE SpectrumFull Text External Link Indicator
"Eighty-six years after Werner Heisenberg first described his eponymous uncertainty principle, experts are still arguing over what, exactly, the infamous inequality really means. Briefly, of course, the principle says that the product of the uncertainties of position and momentum will always be greater than a constant —though a very, very tiny constant (*see note below). The more tightly you tie one factor down, the more the other swings.

But does it mean that the act of measuring position changes the momentum, and vice-versa—the observer effect? Or does it mean that the particle simply doesn’t have precisely defined momentum and position to measure?" Douglas McCormick

Nanoparticles Promise to Make LEDs Cheaper
29 Jul | IEEE SpectrumFull Text External Link Indicator
"Light-emitting diode (LED) light sources have a lot going for them. They have longer life spans than their incandescent rivals and better luminous efficiency, and they’re environmentally friendlier. But those benefits come at a high cost—literally.

There are a number of points in the production of LEDs worthy of attack, such as the bases on which they're grown. Another involves scarce rare-earth metals, a problem endemic to high-tech manufacturing. Now researchers at the University of Washington (UW) have come up with a nanoparticle that could replace the rare-earth-element phosphors currently used in LEDs to soften the harsh blue light they emit." Dexter Johnson
China Unveils Secret Quantum Communications Experiment
29 Jul | IEEE SpectrumFull Text External Link Indicator
"The long vaunted promise of quantum cryptography is the ability to beam a message across the planet with supposedly unhackable encryption, and the competition to develop the best system for doing just that is heating up. Just last month, Canadian researchers detailed their plans in IEEE Spectrum to launch a host of microsatellites created from commercially available, off-the-shelf technologies, and estimated that they could have a working prototype later this year. Now, the Chinese have also revealed their intentions to launch a quantum satellite experiment into orbit by 2016." Davey Alba
Millimeter Waves May Be the Future of 5G Phones
29 Jul | IEEE SpectrumFull Text External Link Indicator
"If analysts’ prognostications are correct, just about every physical object we see—clothes, cars, trains, tractors, and, well, some of us—will be connected to mobile networks by the end of the decade. The 50 billion or so sensors and tracking tags analysts envision will transmit a thousand times as much data as today’s mobile gadgets, at speeds up to 100 times as fast as those that existing 4G networks can support. Accommodating all that traffic will require a fifth generation of wireless technology. Fortunately, Samsung engineers are already at work on millimeter-wave transceiver technology, which could enable gigabit-per-second mobile broadband by 2020." Ariel Bleicher

"Conceptual artist and self-described experimental philosopher Jonathon Keats has previously snapped up San Francisco real estate in extra dimensions, exhibited paintings based on the average color of the universe (beige, in case you were wondering), and created television programming for plants."
