The group report their findings this week in The Journal of Chemical Physics.
Despite the importance of predicting solubility, it is not an easy matter. One approach, using “brute force” simulations, requires long computing times.

Clostridium botulinum is the bacterium that causes the neurointoxication, which produces one of the most potent toxins on earth and is classified as a potential bioterrorism threat. While no cure exists—and botulism treatment options are limited—a serendipitous discovery by scientists at The Scripps Research Institute (TSRI) may provide a new therapy that can stop the neurotoxin even in its more severe, advanced stages of action.
First, diesel vehicles tainted their reputation with soot particles, then high nitric oxide emissions. So are owners of new gasoline cars environmentally friendly? Not always, says a new study led by Empa scientists: some direct-injection gasoline engines emit just as many soot particles as unfiltered diesel cars did in the past. Particle filters can remedy this.
Technion researchers say a combination of metals and organic acids is an effective way to eradicate cholera, salmonella, pseudomonas, and other pathogenic bacteria. The combination also works on bacteria that attack agricultural crops.

These algorithms will be incorporated in an upcoming release of the widely used NWChem computational chemistry software suite later this year.
New research into osmosis-driven behavior now provides a more granular theoretical understanding of the deterministic mechanisms, appearing as a pair of publications this week in The Journal of Chemical Physics. The first paper deconstructs the molecular mechanics of osmosis with high concentrations, and generalizes the findings to predict behavior for arbitrary concentrations. The second piece of the study then simulates via molecular modeling two key forms of osmotic flow in a broadly utilizable way.

Bisphenol A (BPA) is a chemical that is used in a variety of consumer products, such as food storage containers, water bottles and certain resins. In previous studies, Cheryl Rosenfeld, an investigator in the Bond Life Sciences Center, along with other researchers at the University of Missouri, Westminster College and the Saint Louis Zoo, determined that BPA can disrupt sexual function and behavior in painted turtles. Now, the team has identified the genetic pathways that are altered as a result of BPA exposure during early development.
Research findings to be published about new blood test technology that will greatly reduce errors in labwork and improve care in public health and infectious disease. Press briefing scheduled for May 16, reserve press access to live virtual event now.
A study at the University of Nebraska Medical Center (UNMC) found that a novel device can significantly reduce contamination of blood cultures, potentially reducing risky overtreatment and unnecessary use of antibiotics for many patients. This approach could also substantially reduce healthcare costs, according to the study. Thousands of U.S. patients get their blood drawn every day for blood cultures in order to diagnose serious infections such as sepsis, which can be a deadly condition. A small but significant percentage of the blood cultures are contaminated, due in part to skin fragments containing bacteria that are dislodged during a blood draw. This leads to false results that can mislead clinicians into thinking a patient has a potentially serious bloodstream infection. The consequences are costly and put patients at risk.
Newswise hosts a virtual live press briefing on upcoming journal study with research results concerning a new blood collection technique that reduces contamination of blood samples and improves treatment outcomes.
Stop-and-go traffic is typically a source of frustration, an unneccesary hold-up on the path from point A to point B. But when it comes to the molecular machinery that copies our DNA into RNA, a stop right at the beginning of the path may actually be helpful. Recent research from the Stowers Institute for Medical Research shows that this stop prevents another machine from immediately following the first, presumably to better control the traffic and avoid later collisions.
Scientists for the first time have assembled a "disease in a dish" model that pinpoints how a defect in the blood-brain barrier can produce an incurable psychomotor disorder, Allan-Herndon-Dudley syndrome.

Researchers are exploring how molecular simulations with the latest optimization strategies can create a more systematic way of discovering new materials that exhibit specific, desired properties. More specifically, they did so by recasting the design goal to the microscopic, asking which interactions between constituent particles can cause them to spontaneously “self-assemble” into a bulk material with a particular property. To find the answer, reported this week in The Journal of Chemical Physics, they decided to zero in on how composite particles spatially organize themselves.

ITHACA, N.Y. – When you spill pasta sauce on your favorite shirt but there is no trace of it after being washed, you can thank oleophobicity, a resistance to oil commonly applied to textiles. That resistance, however, comes at a price. The coating that makes textiles oil resistant is fluorine-based and breaks down into chlorofluorocarbon gas, a greenhouse gas harmful to the environment.
