An interdisciplinary team of researchers at NRL and the Air Force Research Laboratory have developed a way to directly write quantum light sources, which emit a single photon of light at a time, into monolayer semiconductors.
Counter to a lot of public opinion, having a mental illness does not necessarily make a person more likely to commit gun violence. According to a new study, a better indicator of gun violence was access to firearms.
By bombarding an ultrathin semiconductor sandwich with powerful laser pulses, physicists at the University of California, Riverside, have created the first 'electron liquid' at room temperature. The achievement opens a pathway for development of the first practical and efficient devices to generate and detect light at terahertz wavelengths -- between infrared light and microwaves. Such devices could be used in applications as diverse as communications in outer space, cancer detection, and scanning for concealed weapons.
A new gas detector, developed by researchers at UBC's Okanagan campus, enables highly accurate odour analysis for so many different applications it has been nicknamed the 'artificial nose.' Researchers in the School of Engineering have developed a state-of-the-art microfluidic gas detector that can detect small traces of gases quickly and efficiently. It has a number of potential uses including environmental monitoring, food and beverage quality assessments, and biological and chemical analytical systems.
Exercise can protect both muscle and nerves from damage caused by the restoration of blood flow after injury or surgery, new research from the University of Virginia School of Medicine shows.
Researchers have developed a new technique that allows them to assess radiation exposure in about an hour using an insulator material found in most modern electronics. The technique can be used to triage medical cases in the event of a radiological disaster.
Microneedles able to draw relatively large amounts of interstitial fluid -- a liquid that lurks just under the skin -- opens new possibilities. Previously, microneedles -- tiny, hollow, stainless steel needles -- have drained tiny amounts of interstitial fluid needed to analyze electrolyte levels but could not draw enough fluid to make more complicated medical tests practical. The new method's larger draws could be more effective in rapidly measuring exposure to chemical and biological warfare agents as well as diagnosing cancer and other diseases.
Monoamine oxidase inhibitors are potential drug candidates within therapeutics of different neuropsychological and neurodegenerative disorders including anxiety, depression and Parkinson's disease. Our findings revealed a good correlation between experimental MAO inhibition and docking score by computational studies. Notably, the compounds with remarkable MAO inhibitory potential were also observed as potential antioxidants.
Researchers from the U.S. Army and top universities discovered a new way to get more energy out of energetic materials containing aluminum, common in battlefield systems, by igniting aluminum micron powders coated with graphene oxide.
America lost 20,360 children and teens in 2016 -- 60 percent of them to preventable injuries, a new study shows. But while death rates from the top cause -- motor vehicle crashes -- have declined steadily since 1999, rates from the second-leading cause -- firearms -- have gone up. It's the first time all causes of child and adolescent death have been tallied by both mechanism and intent.
