Gut bacteria byproduct protects against Salmonella

Researchers at the Stanford University School of Medicine have identified a molecule that serves as natural protection against one of the most common intestinal pathogens. Propionate, a byproduct of metabolism by a group of bacteria called the Bacteroides, inhibits the growth of Salmonella in the intestinal tract of mice, according to the researchers. The finding may help to explain why ...

Researchers turn powerful, viscous disinfectants into breathable mist for the first time

A team of engineers and physicians in San Diego have developed a device that diffuses potent disinfectants for airborne delivery. Notably, the device works on a range of disinfectants that have never been atomized before, such as Triethylene glycol, or TEG. In a study published in the August issue of Applied Microbiology and Biotechnology, the team used the device to ...

Researchers improve screening rates for West Virginia’s second-deadliest cancer

In West Virginia, where colorectal cancer is the second-deadliest type of cancer, half of all colorectal cancers elude diagnosis until they have already grown beyond the colon. With Medicaid expansion, more West Virginians now have health insurance for cancer screening, yet many barriers to screening persist. West Virginia University researchers are working to improve screening rates for the state, which ...
