Laser X-rays to nab nuclear smugglers

With over 100 million cargo containers in transit each year, screening them for illicit nuclear material is a major problem. To keep commerce flowing while maintaining an eye on nuclear terrorism and smuggling, a team of scientists at the University of Nebraska-Lincoln (UNL) is developing a laser-based X-ray machine that can image a uranium disk the size of a stack of three US nickels hidden between three-inch (7.6 cm) steel panels.Read More

Mid-air holograms respond to human touch

Researchers from Tsukuba University in Japan have created holograms that respond to human touch. Involving femtosecond lasers, which can stimulate physical matter to emit light in 3D form, the research could eventually lead to the creation of holograms that humans are able to interact with.Read More

Review: Blaze bike light uses a laser to keep cyclists safer

According to a study conducted by the UK's Transport Research Laboratory, 79 percent of bicycle-vs-car accidents occurred when drivers maneuvered into the path of cyclists travelling at speed. In order to help lower that number, University of Brighton product design student Emily Brooke created the Blaze Laserlight as a final-year project. The bicycle headlight is designed to let motorists know that a bike is approaching, by laser-projecting an image of a bicycle onto the road approximately six meters (20 ft) in front of the rider. Four years and one successful Kickstarter campaign later, the Laserlight is now available to buyers in North America. We recently had a chance to try it out for ourselves.Read More

First liquid-cooling laser could advance biological research

In a world where lasers are sci-fi's weapon of choice for melting away an enemy spaceship (sometimes even translating to the real world), researchers at the University of Washington have swum against the current and produced the first laser capable of cooling liquids. The technology could be especially useful for slowing down single cells and allow scientists to study biological processes as they happen.Read More

New technique may make materials hotter than the Sun's core in 20 quadrillionths of a second

If some people get impatient waiting for a soft-boiled egg to cook, that's nothing compared to a group of theoretical physicists at the Imperial College London. They've come up with a new method that could allow lasers to heat certain materials to temperatures hotter than at the Sun's core in 20 quadrillionths of a second. The new technique would reportedly be 100 times faster than the world's most energetic laser system at the Lawrence Livermore National Laboratory, California, and may one day have applications in future fusion research.Read More

Asteroid Impact Mission sets sights on new laser communications record

Laser-based communications has the ability to beam enormous amounts of data at high speed, but the use of this technology in space is still in its infancy. To help push things along, ESA’s proposed Asteroid Impact Mission (AIM) will carry out a record-setting demonstration of space laser communications across a distance of 75 million kilometers while orbiting a binary asteroid.Read More

NASA tests CubeSat-based laser communications

NASA has teamed up with The Aerospace Corporation of El Segundo to test a new CubeSat-mounted laser communication system. While the mission, known as the Optical Communications and Sensor Demonstration (OCSD), has already been successfully placed in orbit, the team is currently working to resolve an issues with its attitude control system.Read More
