World's fastest 2D camera captures 100 billion frames per second

By - December 3, 2014
Researchers at Washington University in St.Louis have built what they claim is the world's fastest 2D receive-only camera, which is able to capture images at a rate of up to 100 billion frames per second. Using a technique called Compressed Ultrafast Photography (CUP), the researchers have so far taken photographs of a number of properties of light propagation and behavior that are already pushing the dimensional limits of fundamental physics.

Quantum memory storage to help quantum communications go the distance

By - November 30, 2014
The technologies made possible by breakthroughs in quantum physics have already provided the means of quantum cryptography, and are gradually paving the way toward powerful, practical, everyday quantum computers, and even quantum teleportation. Unfortunately, without corresponding atomic memories to appropriately store quantum-specific information, the myriad possibilities of these technologies are becoming increasingly difficult to advance. To help address this problem, scientists from the University of Warsaw (FUW) claim to have developed an atomic memory that has both exceptional memory properties and a construction elegant in its simplicity.

Chevy scorches the virtual track with the laser-powered Chaparral 2X

By - November 24, 2014 28 Pictures
After seeing Chevy's sneak preview of the Chaparral 2X Vision Gran Turismo, we got the idea that it was going to be the most extreme Vision Gran Turismo yet, both in terms of styling and technology. We weren't disappointed when Chevy pulled the cloth off at the LA Auto Show last week. The radical racer uses a highly conceptual laser powertrain to rattle the track with 900 hp of thrust. Read More

BAE proposes smart countermeasure system to protect US airborne forces

By - November 19, 2014
BAE Systems has submitted a proposal to the US Army’s Common Infrared Countermeasure (CIRCM) program. Once operational, BAE's system will safeguard rotary and light-fixed wing aircraft, increasing survivability against the threat posed by infrared missiles. CIRCM is designed to work alongside an infrared warning system and a flare dispenser – a commonly-used countermeasure that confuses a guided missile into seeking the heat from the flare rather than that emitted by the target aircraft.

Laser defense system zaps drones out of the sky

By - November 4, 2014
Drones cruising through Chinese airspace may be set for rude awakening, with local scientists reportedly developing a laser capable of shooting the vehicles out of the sky. Chinese media are reporting that researchers from the China Academy of Engineering Physics have been working on a laser defense system to safeguard against the proliferating technology, and its early testing has been largely viewed as a success.

What "Star Wars" laser bolts would actually look like

By - October 22, 2014 3 Pictures
It's no secret that Star Wars is full of scenes that defy the laws of physics. From space battles inspired by WW I and II dogfights to beams of light clashing in lightsaber duels. The laser bolts fired from Han Solo's trusty blaster and Luke's X-wing also play by their own rules, traveling much slower than the speed of light and being perfectly visible in the vacuum of space. Researchers in Poland have now created a film to show what a laser bolt would actually look like. Read More

Reversible tractor beam can repel and attract objects

By - October 20, 2014
We're still a far cry from Star Trek's ship-towing and repelling technology, but laser physicists at the Australian National University (ANU) have built a tractor beam that can repel and attract objects. The beam moved spherical glass shells one fifth of a millimeter in diameter across a distance of up to 20 centimeters (7.87 in), which is around 100 times further than previous experiments at this scale, using only a single hollow laser beam that's bright around the edges and dark in its center.
