Research conducted by food science faculty at the University of Idaho and Washington State University indicate that a commercially available fruit and vegetable wash, when used in a food-manufacturing setting, can dramatically decrease the number of disease-causing organisms in produce-processing washwater. That could reduce by manyfold the potential for cross-contamination within the water by such "gram-negative" bacteria as Salmonella and E. coli O157:H7.

Scientists have come an important step closer to the quantum computer. "Our results give us, for the first time, the possibility to understand the interaction between just two electrons placed next to each other in a carbon nanotube. A groundbreaking discovery, which is fundamental for the creation of a quantum mechanical bit, a so-called quantum bit -- the cornerstone of a quantum computer," explains Henrik Jørgensen, who is one of the many researchers competing on an international level to be the first to make a quantum bit in a carbon nanotube.
