MIT researchers have found a new way of verifying nuclear weapons reduction agreements without revealing secret information, using a physical cryptographic key and nuclear resonant phenomena.
Army scientists, with a team of researchers from the University of Maryland and the National Institute of Standards and Technology, have created a water-based zinc battery that is simultaneously powerful, rechargeable and intrinsically safe.
Researchers at Pacific Northwest National Laboratory have developed and successfully tested a novel process -- called Friction Stir Dovetailing -- that joins thick plates of aluminum to steel. The new process will be used to make lighter-weight military vehicles that are more agile and fuel efficient.
Computer simulations of peregrine falcon attacks show that the extreme speeds reached during dives from high altitudes enhance the raptors' ability to execute maneuvers needed to nab agile prey that would otherwise escape. Robin Mills and colleagues of the University of Groningen, Netherlands, and Oxford University, UK, report this discovery in PLOS Computational Biology.
Researchers have developed a device for upgrading mass spectrometers, which are used to analyze the chemical makeup of unknown substances. The new device analyzes one substance from four different perspectives. Alternatively, it enables multiple samples to be examined simultaneously. By contrast, conventional mass spectrometers analyze one substance at a time.
A team led by Berkeley Lab scientists has developed a process for creating ultrathin, self-assembling sheets of synthetic materials that can function like designer flypaper in selectively binding with viruses, bacteria, and other pathogens. The new platform could potentially be used to inactivate or detect pathogens.
The Department of Homeland Security could benefit from a reliable, real-time instrument that could scan the atmosphere for toxic agents in order to alert communities to a biological or chemical attack. UCF optics and photonics Professor Konstantin Vodopyanov is developing just such a technology to accomplish that.
New research shows that stainless steel composite metal foam (CMF) can block blast pressure and fragmentation at 5,000 feet per second from high explosive incendiary (HEI) rounds that detonate only 18 inches away.
In a breakthrough that could lead to a new class of materials with functions found only in living systems, scientists at the University of California, Berkeley, have figured out a way to keep certain proteins active outside of the cell. The researchers used this technology to create mats that can soak up and trap chemical pollution.
Researchers created small copies of asteroids in the laboratory, and then destroyed them with lasers. The nanosecond laser pulse served as an experimental substitute for a nuclear explosion. The experiments showed high efficiency of nuclear anti-asteroid defense. The study suggests the most effective asteroid destruction criteria, such as the explosion energy needed to eliminate a dangerous object on a collision course with Earth.
