Using red/blue filters (anaglyph), polarized (passive) or LED shutter (active) glasses are relatively simple ways of creating a 3D effect. Creating 3D pictures without viewers having to don any form of eyewear is a little trickier and is made even more so if you want really big 3D effects for a sports stadium or a billboard. To help address this, Austrian scientists working at the Vienna University of Technology (TU Vienna) and the company TriLite Technologies have developed a new kind of display just for this purpose that sends beams of light directly to the viewers’ eyes via a laser and a sophisticated mirror system.

Imagine laser tag with a million players all on the one battlefield. It's ridiculous to even think about, but the creators of iTager claim that their system makes it possible. It's a ground-up reimagining and re-engineering of laser tag replete with fully-wireless, remote-controllable systems that work in all weather conditions over a whopping 2,500 ft (760 m) and that can easily be mounted onto existing laser tag weapons (or even your hand or a bicycle) or purchased preinstalled on rifles the creators made themselves.

Lasers have been used to analyze the bones of sailors who drowned when the Royal Navy warship the Mary Rose sank in 1545. The new non-destructive technique carried out by the Royal National Orthopaedic Hospital in Stanmore, North London, shows that the men suffered from rickets, shedding new light on nutrition in Tudor England.

The laser goes from the weapon of tomorrow to the weapon of today as the US Navy announces the completion of its successful deployment of the Office of Naval Research's (ONR) Laser Weapon System (LaWS). The deployment is the first on a US Naval vessel and took place on the USS Ponce (LPD-15) in the Arabian Gulf from September to November of this year. Read More
Taking careful aim with a quadrillion watt laser, researchers at the US Department of Energy’s Lawrence Berkeley National Lab claim to have managed to speed up subatomic particles to the highest energies ever recorded for a compact accelerator. By blasting plasma in their tabletop-size laser-plasma accelerator, the scientists assert that they have produced acceleration energy of around of 4.25 giga-electron volts. Acceleration of this magnitude over the short distances involved correlates to an energy rise 1,000 times greater than that of a traditional – and very much larger – particle accelerator. Read More
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.

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.

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
Should you ever be captured while checking out a crazed villain's secret headquarters, it's entirely possible that a burning laser might provide you with your only means of escape. Of course, anything that's obviously a laser will be taken from you ... which is why our favorite laser weapons hobbyist, Patrick Priebe, has created a "Bond-inspired LaserWatch." Read More
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.
