The vortex ring gun is an experimental non-lethal weapon for crowd control that uses high-energy vortex rings of gas to knock down people or spray them with marking ink or other chemicals.
The concept was explored by the US Army starting in 1998, and by some commercial firms. Knockdown of distant individuals currently seems unlikely even if the rings are launched at theoretical maximum speed.[1] As for the delivery of chemicals, leakage during flight is still a problem.[ citation needed ]
Weapons based on similar principles but different designs and purposes have been described before, typically using acetylene-air or hydrogen–oxygen explosions to create and propel the vortices.[2].
You’ve probably heard of Schrödinger’s cat, the unfortunate feline in a box that is simultaneously alive and dead until the box is opened to reveal its actual state. Well, now wrap your mind around Schrödinger’s time, a situation in which one event can simultaneously be the cause and effect of another event.
Scientists have produced and tested, in mice, a vaccine that protects against a worrisome superbug: a hypervirulent form of the bacteria Klebsiella pneumoniae. And they’ve done so by genetically manipulating a harmless form of E. coli, report researchers at Washington University School of Medicine in St. Louis and VaxNewMo, a St. Louis-based startup.
Klebsiella pneumoniae causes a variety of infections including rare but life-threatening liver, respiratory tract, bloodstream and other infections. Little is known about how exactly people become infected, and the bacteria are unusually adept at acquiring resistance to antibiotics. The prototype vaccine, details of which are published online Aug. 27 in Proceedings of the National Academy of Sciences, may offer a way to protect people against a lethal infection that is hard to prevent and treat.
“For a long time, Klebsiella was primarily an issue in the hospital setting, so even though drug resistance was a real problem in treating these infections, the impact on the public was limited,” said co-author David A. Rosen, MD, Ph.D., an assistant professor of pediatrics and of molecular microbiology at Washington University. “But now we’re seeing Klebsiella strains that are virulent enough to cause death or severe disease in healthy people in the community. And in the past five years, the really resistant bugs and the really virulent bugs have begun to merge so we’re beginning to see drug-resistant, hypervirulent strains. And that’s very scary.”
Ransomware attacks have more than doubled this year, as criminals turn to powerful new forms of file-locking malware and additional attack techniques to conduct campaigns that are more lucrative than ever before.
FINDLAY, Ohio — Pharmacy students at the University of Findlay believe they’ve developed a new drug that could target the most aggressive form of cancer occurring in the brain.
The oral compound, RK15, targets glioblastomas, an aggressive brain cancer. The disease has a 10 percent, five-year survival rate.
If it’s successful, the medication would remove the need for risky medical procedures which require physical access to brain tissue, according to the University of Findlay.

Researchers have launched a new database dedicated to mapping and understanding the complexity of cellular senescence in a bid to help us fully understand this age-related phenomenon.
Introducing the CellAge database
The Human Ageing Genomic Resources ( HAGR ) is a series of databases and tools that have been developed to aid researchers on aging and help them study the genetic elements of human aging. The databases utilize modern techniques, such as functional genomics, network analyses, systems biology, and evolutionary analyses, to build what is one of the most valuable resources available today.
Nice job by Brookhaven.
A team of scientists have designed, created, and successfully tested a new algorithm to make smarter scientific measurement decisions. The algorithm, a form of artificial intelligence (AI), can make autonomous decisions to define and perform the next step of an experiment.
