A team of researchers has developed an algorithm for predicting the effect of an external electromagnetic field on the state of complex molecules. The new algorithm, presented in a paper in The Journal of Chemical Physics, enables researchers to look inside large polyatomic molecules, observe and potentially control electron motion therein.
The accident at Japan's Fukushima Daiichi nuclear power station in 2011 raised grave concerns about radioactive material released into the environment, including concerns over radiation-induced thyroid cancer. Ultrasound screenings for thyroid cancer were subsequently conducted in the Fukushima Health Management Survey. This observational study group includes about 324,000 people 18 or younger at the time of the accident and it reports on two rounds of ultrasound screening during the first five years after the accident.
To help determine if the descendants of Gulf War and post-9/11 veterans are at risk for health effects resulting from the service members' exposure to toxicants during deployment, a new report from the National Academies of Sciences, Engineering, and Medicine recommends the creation of a health monitoring and research program (HMRP).
Researchers and cybersecurity experts have begun to examine ways to mitigate the risk of cyberattacks in medical imaging before they become a real danger.
Researchers at the University of Illinois at Urbana-Champaign have developed a stamp-sized sensor that can detect trace amounts of certain chemical warfare agents, such as sarin, within minutes. The research is published in ACS Omega.
A weapons of Staphylococcus aureus is α-toxin, which destroys host cells by forming pores in their membranes. Researchers at UNIGE have identified the mechanism that allows these pores to be harmful. They uncover how proteins of human cells assemble into a complex to which pores are docked. They also demonstrate that blocking the assembly of the complex by removing one of its elements allows pores to be removed from the membrane and cells to survive.
Freiburg scientists elucidate the mechanism for the transport of water-insoluble protein molecules in mitochondria
The latest in a series of congressionally mandated biennial reviews of the evidence of health problems that may be linked to exposure to Agent Orange and other herbicides used during the Vietnam War found sufficient evidence of an association for hypertension and monoclonal gammopathy of undetermined significance (MGUS). The committee that carried out the study and wrote the report, Veterans and Agent Orange: Update 11 (2018), focused on the scientific literature published between Sept. 30, 2014, and Dec. 31, 2017.
Scientists from Bradford warn of increased chemical weapons risk during a period of very rapid scientific change.
Researchers have identified a compound that strongly inhibits botulinum neurotoxin, the most toxic compound known. That inhibiting compound, nitrophenyl psoralen (NPP), could be used as a treatment to reduce paralysis induced by botulism. Botulinum neurotoxin is considered a potential bioweapon because there is no FDA-approved antidote. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
