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.
Mortality rates were higher during the nine months of military liberation of Mosul, Iraq, than during the 29 months of exclusive Islamic State of Iraq and Syria (ISIS) control, according to a study published this week in PLOS Medicine. The population-based survey demonstrated that high mortality rates resulted from the military offensive despite the use of modern precision-targeted ordnance.
The contribution of economic, social and cultural rights to sustaining global peace is largely overlooked within new developments to tackle violent conflict, says new research led by Lancaster University.
A Northwestern University and Argonne National Laboratory research team has developed an exceptional next-generation material for nuclear radiation detection that could provide a significantly less expensive alternative to detectors now in commercial use. Specifically, the high-performance material is used in a device that can detect gamma rays, weak signals given off by nuclear materials, and can easily identify individual radioactive isotopes. Potential uses include more widespread detectors for nuclear weapons and materials as well as applications in biomedical imaging, astronomy and spectroscopy.
