Atomic clusters, consisting of a few to a few thousand atoms, have emerged over the past 40 years as the ultimate nanoparticles, whose structure and properties can be controlled one atom at a time. More importantly, the possibility of creating a new class of materials, composed of clusters instead of …

More than thirty countries produce mines, and twenty countries export them. Iran has reportedly laid several thousand naval mines, North Korea’s 50,000, China 100,000 or so, and Russia estimated quarter-million. Since World War II, sea mines have damaged or sunk four times more U.S. Navy ships than all other means …

Gun-launched guided munitions are of tremendous interest to the U.S. Army. These technologies offer more accuracy, extended range through glide, more favorable terminal approach for lethality, and the ability to engage advanced threats like partially hidden (defilade) and moving ground and air targets. Current gun-launched guided munition technologies are limited to indirect …

Artificial intelligence expert George Zarkadakis believes robots could have sex with each other to evolve and produce superior offspring and this scary new world could be closer than we might imagine. He predicts that humans could even breed with machines to create new hybrid species. Mr Zarkadakis said robots that …

Quantum walks are the quantum version of classical random walks, which are a mathematical means for describing a natural random walk, e.g., simply wandering around randomly.   In a “classical random walk”, you could imagine someone starting at the centre of a city, and making a random decision at each …

As the space domain has become more congested and militarized  the potential for intentional and unintentional threats to space system assets has increased. To mitigate these threats, the Department of Defense (DOD) has undertaken a variety of initiatives to enhance its network of sensors and systems to provide space situational awareness …

DARPA has launched a new surveillance program which plans to use genetically engineered plant as battlefield surveillance sensors. DARPA’s new Advanced Plant Technologies (APT) program looks to seemingly simple plants as the next generation of intelligence gatherers. Traditional sensors are not always optimal for  obtaining timely, accurate information as national security …

China is developing a new type of spy satellite using ghost imaging technology which could spot stealth aircraft and see through smokescreens and camouflage.   Ron Meyers, quantum physicist at the Army Research Laboratory. Meyers explained ghost imaging, a technique that allows a high resolution camera to produce an image …

Smartphones carried by most people depend on cell site or cell tower for their operation.  A cell site or cell tower is a cellular telephone site where antennae and electronic communications equipment are placed — typically on a radio mast, tower, or other raised structure — to create a cell …
