A Stanford team has demonstrated a unique system that can generate a strong sonar wave, and read and interpret the reflected signals, from an airborne platform. This raises the possibility of sonar-enabled drones that could finally map the sea floor.

Back in September, Sony launched a flagship 4K laser projector capable of putting out 10,000 lumens. Though Epson America's latest projector can't match the resolution, the Pro L30000UNL is a much brighter prospect.

Lightning is a major trigger for wildfires, like the record-breaking blazes that devastated Australia and California this year. But what if we could redirect lightning to strike safely? Graphene particles trapped in a tractor beam could do just that.

Acer has revealed a bunch of consumer and commercial LED and laser projectors at its October press conference, including best-in-class LED wireless models and a series claimed to be the world's most efficient 3,100-lumens laser projectors.

When NASA’s newest rover touches down on Mars, it will carry with it a set of mirrors that will serve as targets for future laser-wielding spacecraft. The laser-bouncing tech is similar to that used in the Apollo era, to characterize the Moon.

A team of scientists at the University of St Andrews has developed a laser spectroscopy technique that can determine the authenticity of expensive vintage whiskey without having to open the bottle to retrieve a sample for analysis.

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. Known as “spacetime wave packets,” these lasers follow different rules of refraction, which could lead to new communication technologies.

A team of ESA scientists has developed a way to use lasers, special telescopes, detectors, and light filters tuned to specific wavelengths to increase contrast with the sky and accurately track space debris even in broad daylight.

In the advanced stages of Parkinson's disease, some people develop a condition known as "gait freeze," in which they temporarily lose the ability to step forward. NexStride is designed to help, though, by giving them a laser target for their feet.

When it comes to rough, tough, gruff, no-nonsense devices, power drills certainly fit the bill. Nonetheless, a Canadian company has given the tool a high-tech makeover, adding what are actually some pretty handy features.

The Linac Coherent Light Source (LCLS) is an extremely powerful X-ray laser – and now it's about to get even more powerful. The second generation of the instrument has now achieved first light, with scientists demonstrating fine control of the beam.

Radio waves travel poorly through the water, which makes it difficult for divers or submersibles to wirelessly transmit information to the surface. Scientists are trying to change that, though, by developing an underwater version of Wi-Fi.
