Exposure to banned nerve agents remains a major public health concern globally, especially because of the recent air-release of these agents in Syria. One main problem is the difficulty of determining whether an exposure has occurred. Now, a new study demonstrates that the mammalian microbiome can act as a 'sentinel' due to its high responsiveness to exposure.
Scientists at the Research Institute of the McGill University Health Centre (RI-MUHC) in Montreal have identified new means of fighting drug-tolerant bacteria, a growing global threat as menacing as drug-resistant microbes. Little is known about the mechanisms leading to tolerance, a strategy that makes bacteria 'indifferent' to antibiotics and almost 'un-killable,' which results in chronic infections extremely difficult to treat and cure.
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.
By analyzing genomic sequences from more than 400 strains of the bacterium that causes anthrax, researchers have provided the first evidence that the severity -- technically known as virulence -- of specific strains may be related to the number of copies of certain plasmids they carry.
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.
A team headed by Manuel Serrano at IRB Barcelona has designed a drug encapsulation system that selectively targets senescent cells. The study paves the way for therapeutic approaches to eliminate senescent cells in many diseases, such as pulmonary fibrosis and cancer.
