Using an abandoned U.S. military base in Greenland as a case study, new Brown research explores how the impact of climate change on domestic and overseas military bases could cause a host of political and diplomatic problems.
Sensors that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person's breath. Researchers from Drexel University and the Korea Advanced Institute of Science and Technology have made a discovery that could make our best 'chemical noses' even more sensitive.
A highly versatile deposition process already used to manufacture aircraft parts and other expensive, delicate surfaces is now 3-D modeled to show the effects of temperature for the first time. Cold gas dynamic spray (CGDS) can bond supersonic micron-sized metal particles to a metal or polymer surface without damaging it. This 3-D model of a single particle bonding to a surface starts unlocking a grand high-technology challenge several decades in the making.
In a new study, USC Viterbi School of Engineering professors used computer-based models to identify mechanisms or 'strategies' used by bacterial spores to evade attack from extreme temperatures, chemicals and radiation. Using complex mathematical techniques to examine spores at the molecular level, the team also determined the optimal conditions for killing harmful bacteria.
University of Washington researchers reconstructed prehistoric projectiles and points from ancient sites in what is now Alaska and studied the qualities that would make for a lethal hunting weapon. By examining and testing different projectile points, the team has come to a new understanding about the technological choices people made in ancient times.
Male rats exposed to air blasts designed to mimic those from explosives used in recent military conflicts have symptoms of post-traumatic stress disorder (PTSD) that are improved by a drug currently being evaluated in humans for treatment-resistant depression and suicidal tendencies. The research, published in eNeuro, provides a new direction for addressing the mental health problems that often arise following a common brain injury in veterans.
Scientists from the US Army Research Laboratory and the Lawrence Livermore National Laboratory found a solution to a significant challenge in making high-energy explosives.
Ethicists from the University of Basel have outlined a new biosecurity framework specific to neurotechnology. While the researchers declare an outright ban of dual-use technology ethically unjustified, they call for regulations aimed at protecting the mental privacy and integrity of humans. The journal Neuron has published the study.
Researchers at the US Army Research Laboratory and the Ludwig Maximilian University in Munich, Germany, have developed an environmentally friendly red light flare popular in fireworks displays and among Soldiers who use them in training and battlefield operations as signaling devices.
An joint research team, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced the Hybrid-SOEC system with highest reported electrochemical performance in hydrogen production.
