Turret flight tests to pave the way for laser weapons on military aircraft

By - September 17, 2014 2 Pictures
High energy laser (HEL) systems have been the subject of military research for decades, but it is only in recent years that the technology has advanced to the point where it is feasible for such systems to be mounted on military ground vehicles and sea vessels. Initial flight tests have now been conducted on a new aircraft laser turret that will help pave the way for HEL systems to be integrated into military aircraft. Read More

NASA probe will reveal 3D architecture of forests from space

By - September 14, 2014 1 Picture
NASA is developing a laser-based instrument for deployment on the International Space Station that will probe the depths of Earth's forests from space in a bid to reveal more about their role in the planet's carbon cycle. After its completion in 2018, this Global Ecosystem Dynamics Investigation (GEDI) lidar will join the likes of the Soil Moisture Active Passive satellite in studying Earth's vegetation on a global scale.

Neither rain, nor fog, nor wind stops Boeing's laser weapon destroying targets

By - September 8, 2014 2 Pictures
If you've ever gone outside on a foggy night and shined a laser pointer about, you’ve seen two things: how flashy a raygun it makes, and the problem laser weapons face in such conditions as fog and rain scatters the energy that should be destroying missiles. However, in recent tests at Eglin Air Force Base in Florida, Boeing and the US Army have shown that their High Energy Laser Mobile Demonstrator (HEL MD) is capable of successfully locking onto and taking out targets in very laser-unfriendly foggy, rainy, and windy maritime conditions.

Fermilab experiment will attempt to answer whether we actually live in "the Matrix"

By - August 31, 2014 5 Pictures
In what may be one of the most mind-bogglingly surreal experiments ever floated, scientists at the US Department of Energy's Fermi National Accelerator Laboratory (Fermilab) will attempt to discover if the universe is "real" or merely a holographic 3-D illusion that we just think is real. Using high-powered lasers, the scientists intend to determine if space-time is a quantum system made up of countless tiny bits of information. Read More

"Nanojuice" lets scientists see the gut in action

By - July 7, 2014 1 Picture
When someone suffers from a gastrointestinal disorder such as celiac disease, Crohn's disease or irritable bowel syndrome, it's standard practice for doctors to take a look at the state of their small intestine. This is typically done by having them drink a rather unpleasant-tasting barium solution, and then submitting to x-rays, an MRI or ultrasound. According to scientists at New York's University at Buffalo, however, all of those imaging techniques have serious shortcomings. Their proposed solution? A stiff drink of nanojuice. Read More

LLNL improving the efficiency of 3D metal printing

By - June 18, 2014 2 Pictures
To paraphrase Samuel Johnson, there was a time when 3D metal printing was like a dog walking on his hind legs – it wasn't done well; but you were surprised to find it done at all. Now that laser sintering or Selective Laser Melting (SLM) is used for everything from printing rocket engine components to semi-automatic pistols, the time for surprise may b long past, but the technology still has plenty of room for improvement. That's why researchers at the Lawrence Livermore National Laboratory (LLNL) are working on simulations to improve the speed of 3D laser printing and the quality of the final product by using higher-powered lasers.
