Compressing photonic signals for greater bandwidth

Cornell researchers have developed an ingenious method to time-compress optical signals. The process could enable optical communication systems to carry many more bits per second or could also be used to generate short bursts of light with complex waveforms needed to control chemistry and physics experiments where changes are induced by light.

Zinc air battery maker looks beyond lithium

Start-up ReVolt Technology is developing rechargeable zinc air batteries, a technology it says promises longer runtime for consumer electronics and plug-in vehicles.

The Switzerland-based company, which was spun out of a Norwegian research institute five years ago, anticipates commercializing a rechargeable coin-size batteries next year. But the technology has the potential to be a cheaper and more energy-dense alternative to lithium ion batteries in consumer electronics, grid storage, and transportation.

High-performance plasmas may make reliable, efficient fusion power a reality

In the quest to produce nuclear fusion energy, researchers from the DIII-D National Fusion Facility have recently confirmed long-standing theoretical predictions that performance, efficiency and reliability are simultaneously obtained in tokamaks, the leading magnetic confinement fusion device, operating at their performance limits. Experiments designed to test these predictions have successfully demonstrated the interaction of these conditions.

Firing up those femtocells

The folks over at the Femto Forum, in conjunction with the European telecommunications standards institute, recently announced a "plugfest" for March 2010. The plugfest will serve as a forum to for interoperability tests among femtocell network gateways, security gateways, femtocell access points and chipsets.

Femtocells are tiny base stations designed for use in residences and branch offices, capable of supporting roughly two to to five phones/mobile devices.

How Terahertz Waves Tear Apart DNA

Great things are expected of terahertz waves, the radiation that fills the slot in the electromagnetic spectrum between microwaves and the infrared. Terahertz waves pass through non-conducting materials such as clothes , paper, wood and brick and so cameras sensitive to them can peer inside envelopes, into living rooms and "frisk" people at distance.
