It appears the U.S. Army is developing and building a laser weapon capable of vaporizing its targets and disrupting enemy tech signals thanks to pulses and signals. This may well be the world's most powerful laser to date.

HP makes some of the best printers on the market today, and a ton of them are on sale right now at discounts of up to $250. You will have to act fast to nab one of these deals, though: This New Year's HP printer sale only lasts until Wednesday, January 2.

In early tests, this laser-activated silk and gold material held wounds together better than stitches or glue

A laser-driven technique for creating fusion that dispenses with the need for radioactive fuel elements and leaves no toxic radioactive waste is now within reach, say researchers.

Why future conflicts could be full of “light.” By Sebastien Roblin.

With its first lasing, the European XFEL reaches the last big milestone before the official opening.

Researchers at the Georgia Institute of Technology and Peking University have found a new use for the ubiquitous PowerPoint slide: Producing self-folding three-dimensional origami structures from photocurable liquid polymers.

For the first time, researchers have measured how antimatter absorbs light. By Davide Castelvecchi.

It's finally happening! By Kyle Mizokami.

Researchers have used the pressure of light—also called optical forces or sometimes “tractor beams”—to create a new type of rewritable, dynamic 3D holographic material… By Lisa Zyga. (Sept. 30, 2016)

It tracks biomarkers to detect cancers and monitor drug delivery.

The NIST team has demonstrated a compact atomic gyroscope design that could, with further development, be portable, low power, and accurate enough to be used for navigation. By Laura Ost.

For years, the Pentagon has pursued the dream of directed energy weaponry — laser weapons that could defeat a foe for pennies when compared with the expensive kinetic weapons the department relies on. And for years, the technology proved to be elusive. But the time has finally come where those weapons are capable of being fielded, according to a trio of Lockheed Martin executives who work on the development of the company’s laser arsenal.

Imagine a three-dimensional aerial hologram that you can feel. You won’t have to imagine it for long; it’s real! Scientists in Japan have created it, but at the moment these holograms are no bigger than 5 cm3.

Lasers are typically used to heat or burn. But new research shows that lasers can cool things, such as water, too. By Olivia Lowenberg.

Physicists have wondered in recent years if they could control how atoms interact using light. Now they know that they can, by demonstrating games of quantum billiards with unusual new rules. In an article published in Physical Review Letters, a team of Univ. of Chicago physicists explains how to tune a laser to make atoms attract or repel each other in an exotic state of matter called a Bose-Einstein condensate.

A team of Japanese scientists has developed a new laser which has the shortest wavelengths ever recorded. The advance could help see microscopic objects like molecules with more clarity than ever.

More luminous and energy efficient than LEDs, white lasers look to be the future in lighting and light-based wireless communication.

Osaka University scientists said they fired the world's most powerful laser beam. It instantaneously concentrated energy equivalent to 1,000 times the world's electricity consumption and entered the record books as the most powerful laser beam ever emitted, the researchers said on July 27. Although the energy of the laser beam itself was only powerful enough to run a microwave for about two seconds, the team was able to attain the massive output...

Lightning dart across the sky in a flash. And even though we can use lightning rods to increase the probability of it striking at a specific location, its exact path remains unpredictable. At a smaller scale, discharges between two electrodes behave in the same manner, streaking through space to create ...
