For centuries, dogs have served in a variety of roles alongside humans, including faithful companion and guardian. The latter function is one that’s seen more focus in recent times as canines have been trained to sniff out buried improvised explosive devices (IEDs) before they are detonated. The dog’s handler also needs to be trained to detect subtle cues from the animal, which is where a video game developed by the US military comes into play. Read More
A team of experts at the US Naval Research Laboratory (NRL) has developed a new way of fabricating spinel, an armor material used in the windows of military vehicles, demonstrating that the strength of transparent ceramics could be dramatically improved. The nanocrystalline spinel is 50 percent harder than the spinel currently used in armored vehicles and could result in enhanced protection for personnel. Read More
Although no one is saying that aircraft carriers will soon be able to fuel their jet fighters using water from the ocean, such a scenario has recently come a step closer to reality. Scientists from the US Naval Research Laboratory (NRL) have successfully flown a radio-controlled airplane that was running purely on fuel derived from sea water. Read More
Back in 2009, the US Naval Research Laboratory (NRL) set an endurance record for electric unmanned aerial vehicles (UAVs) when its fuel cell-powered Ion Tiger aircraft managed to stay aloft for 26 hours and 1 minute. Now, NRL has announced that the same aircraft has trounced that record, by remaining in flight for 48 hours and 1 minute. Read More
The current world record for triple-junction solar cell efficiency is 44 percent, but a collaboration between the U.S. Naval Research Laboratory (NRL), the Imperial College of London, and MicroLink Devices Inc. has led to a multi-junction photovoltaic cell design that could break the 50 percent conversion efficiency barrier under concentrated solar illumination.

Although many people may think that the lenses in our eyes are just like those found in cameras, there is in fact one key difference between the two – while man-made lenses have just a single index of refraction, meaning that they only bend light in one direction, our natural lenses refract light by varying degrees. This is why artificial implanted lenses, such as those used to treat cataracts, can create visual distortions. A new technology, however, now allows for the fabrication of lenses that work just like the ones in our eyes. Read More
With around 430 gas-turbine engines on 129 of its ships burning about US$2 billion worth of fuel every year, the U.S. Navy is examining the potential of using Rotating Detonation Engines (RDEs) to improve fuel consumption and cut costs. Researchers at the Naval Research Laboratory (NRL) estimate that retrofitting RDEs to its fleet could save the Navy approximately 300 to 400 million dollars a year. Read More
