Antibiotic-resistant bacteria are an important concern for disease prevention in the future. UA doctoral candidate Victoria Obergh is testing Tucson-area wastewater systems to find out where these bacteria can be found.
Are you allergic to peanuts and worried there might be some in that cookie? Now you can find out using a rather unlikely source: your cell phone.
A team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a lightweight device called the iTube, which attaches to a common cell phone to detect allergens in food samples. The iTube attachment uses the cell phone’s built-in camera, along with an accompanying smart-phone application that runs a test with the same high level of sensitivity a laboratory would.(more…)
Men who ate a low-fat diet with fish oil supplements for four to six weeks before having their prostate removed had slower cancer-cell growth in their prostate tissue than men who ate a traditional, high-fat Western diet, according to a study by researchers at UCLA’s Jonsson Comprehensive Cancer Center.
The researchers also found a change in the composition of cell membranes in both healthy cells and cancer cells in the prostates of men on the low-fat, fish oil–supplement diet. The membranes had heightened levels of omega-3 fatty acids from fish oil and decreased levels of omega-6 fatty acids from corn oil, which may directly affect the biology of the cells, though further studies are needed, said Dr. William Aronson, the study’s first author and a researcher with the Jonsson Cancer Center.
