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.

Cheap, Printed Solar LEDs To Light Up Off-Grid African Villages

Danish researcher Frederik Krebs has created an LED lamp embedded within a flexible, printable solar panel that could replace the kerosene lamps still used around the developing world.

While sheets of photovoltaics aren't that new, Krebs is the first person to embed LEDs inside those solar panels.

Trident laser accelerates protons to record energies

An international team of physicists at Los Alamos National Laboratory has succeeded in using intense laser light to accelerate protons to energies never before achieved. Using this technique, scientists can now accelerate particles to extremely high velocities that would otherwise only be possible using large accelerator facilities.
