Researchers at King's College London, in collaboration with Northumbria University, have developed a new way of detecting homemade explosives which will help forensic scientists trace where it came from.
A team of scientists has studied a catalyst that decomposes nerve agents, eliminating their harmful and lethal effects. The research was published Friday, April 19, in the Journal of Physical Chemistry Letters.
A new tungsten-based alloy developed at Los Alamos National Laboratory can withstand unprecedented amounts of radiation without damage. Essential for extreme irradiation environments such as the interiors of magnetic fusion reactors, previously explored materials have thus far been hobbled by weakness against fracture, but this new alloy seems to defeat that problem.
During the Vietnam War, United States aircraft sprayed more than 20 million gallons of herbicides, including dioxin-contaminated Agent Orange, on the country's rain forests, wetlands, and croplands. A new article from the University of Illinois and Iowa State University documents the environmental legacy of Agent Orange in Vietnam, including hotspots where dioxin continues to enter the food supply.
Gardeners commonly use nematodes to naturally get rid of harmful soil-dwelling insects. A new study published today in the journal Functional Ecology revealed that these insect-killing nematodes also produce distinctive chemical cues, which deter Colorado potato beetles and make potato leaves less palatable to them.
Researchers from the University of California, Irvine and the University of California, Riverside have uncovered the possibility of an acoustic side-channel attack on the DNA synthesis process, a vulnerability that could present a serious risk to biotechnology and pharmaceutical companies and academic research institutions.
Inspired by the refined electrochemistry of electric car batteries, scientists have developed a battery-like system that allows them to make potential advancements for the manufacturing of medicines. Their new method avoids safety risks associated with a type of chemical reaction known as dissolving metal reduction. Their method would offer significant advantages over current methods of chemical manufacturing, but until now, has largely been sidelined due to safety considerations.
The bottom of the Baltic Sea is home to large quantities of sunken munitions, a legacy of the Second World War -- and often very close to shore. Should we simply leave them where they are and accept the risk of their slowly releasing toxic substances, or should we instead remove them, and run the risk of their falling apart -- or even exploding?
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.
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.
