New plume dispersal model alerts authorities how much time people have to flee after an attack.
According to new study of Syrian War in INFORMS journal Operations Research, unless there is a player so strong it can guarantee a win regardless of what others do, the likely outcome of multilateral war is a gradual stalemate that leads to mutual annihilation of all players.
First responders to major chemical exposure incidents in the United States can improve treatment protocols for at-risk casualties with better communication strategies, according to new analysis in Annals of Emergency Medicine.
Researchers from the University of Texas at San Antonio used computer models on the Stampede2 supercomputer to replicate the dispersal of gases from the April 4, 2017 chemical weapons attack in northwest Syria. The simulations were able to capture real world conditions despite a scarcity of information. Recently, the team developed a coarse model that uses seasonal conditions as background information to speed up calculations, reducing forecasting time from days to minutes.
Once in the territory of science fiction, 'nanobots' are closer than ever to becoming a reality, with possible applications in medicine, manufacturing, robotics and fluidics. Today, scientists report progress in developing the tiny machines: They have made nanobot pumps that destroy nerve agents, while simultaneously administering an antidote. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
Supercrystals grown from tiny particles of gold have finer sensing capabilities than those commonly used to detect the chemicals in drugs or explosives.
Nowadays, the maintenance of wellbore stability is a very important activity in the drilling industry. Wellbore stability can be improved by designing proper drilling fluid.
Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders and scientists in the field identify deadly and difficult-to-detect nerve agents such as VX and sarin.
Nerve agents are scary stuff. They are among the most deadly substances on earth, yet can be odorless, tasteless and difficult to detect. But researchers now report in ACS Central Science that they have adapted building materials normally associated with children's toys and a cell phone to help sense these compounds. The new method can sensitively detect these poisons, quantify the amount and distinguish between different classes present at contaminated sites.
A major new study appearing in PLOS Biology on May 31 examines more than a century of fungal pathogens, finding well-aimed biosecurity measures cut the spread of unwanted fungi into a nation, even in the face of increased globalized trade.
