Researchers at the US Army Research Laboratory and the Robotics Institute at Carnegie Mellon University developed a new technique to quickly teach robots novel traversal behaviors with minimal human oversight.
Nowadays, the maintenance of wellbore stability is a very important activity in the drilling industry. Wellbore stability can be improved by designing proper drilling fluid.
Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders and scientists in the field identify deadly and difficult-to-detect nerve agents such as VX and sarin.
Hunters don camouflage clothing to blend in with their surroundings. But thermal camouflage - or the appearance of being the same temperature as one's environment - is much more difficult. Now researchers, reporting in ACS' journal Nano Letters, have developed a system that can reconfigure its thermal appearance to blend in with varying temperatures in a matter of seconds.
Nerve agents are scary stuff. They are among the most deadly substances on earth, yet can be odorless, tasteless and difficult to detect. But researchers now report in ACS Central Science that they have adapted building materials normally associated with children's toys and a cell phone to help sense these compounds. The new method can sensitively detect these poisons, quantify the amount and distinguish between different classes present at contaminated sites.
Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects -- and people -- practically invisible.
A deep neural network running on an ordinary desktop computer is interpreting highly technical data related to national security as well as -- and sometimes better than -- today's best automated methods or even human experts. The research probes incredibly complex data sets filled with events called radioactive decays.
Drones could be used to detect dangerous 'butterfly' landmines in remote regions of post-conflict countries, according to new research from Binghamton University, State University at New York.
First study of its kind shows how detrimental nuclear attack would be for the aggressor nation.
The decision to acknowledge sponsorship of an attack is often linked to whether the attacker hopes to draw attention to a cause or to actually influence events, says political scientist Evan Perkoski.
