Current cooling technology, such as that found in fridges and air conditioning systems, exploits the changes in temperature when gases are compressed and expanded. This technology often uses environmentally damaging greenhouse gases. The search for materials with large caloric effects…
Biometric verification is any means by which a person can be uniquely identified by evaluating one or more distinguishing biological traits. Unique identifiers include fingerprints, hand geometry, earlobe geometry, retina and iris patterns, voice waves, DNA, and signatures. A record…
In March 2016, DARPA officials launched the Spectrum Collaboration Challenge (SC2), an initiative designed to ensure that the exponentially growing number of military and civilian wireless devices will have full access to the increasingly crowded electromagnetic spectrum particularly between 9…
In an Aug. 17 memorandum from Mick Mulvaney, director of the Office of Management and Budget, and Michael Kratsios, deputy assistant to the president in the Office of Science and Technology Policy, the Trump administration outlines its technology-related research and…
Biological weapons achieve their intended effects by infecting people with disease-causing microorganisms and other replicative entities, including viruses, infectious nucleic acids and prions. The chief characteristic of biological agents is their ability to multiply in a host over time. …
The U.S. Defense Advanced Research Projects Agency (DARPA) and British defense firm BAE Systems have developed a new lightweight, handheld tactical sensor that lets U.S. soldiers easily detect and identify enemy electronic jammers on the battlefield. During Recent ongoing…
Silicon (Si) based microelectronics, that had revolutionized electronics, computing and communications, has reached its limits and researchers are exploring various technologies to replace silicon, that can satisfy humanity’s need for faster, smaller, greener and more powerful computers. One of class…
When in the field, military service members rely on their mobile devices to provide access to wireless networks in areas lacking a communications infrastructure. The protocols used for these networks determine the best config urations, and therefore trust all information…
U C Berkeley engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time.Because these batteryless sensors could also…
Military commanders require means for detecting and anticipating long-term strategic instability. They have to get ahead and stay ahead of conflicts, whether those conflicts are within nation states, between nation states, and/or between non-nation states. In establishing or maintaining security…
