Vacuum Ultraviolet Lamp of the Future Created in Japan

MAPL-Ono-UV-Nagoya-JB.jpg

A team of researchers in Japan has developed a solid-state lamp that emits high-energy ultraviolet (UV) light at the shortest wavelengths ever recorded for such a device, from 140 to 220 nanometers. This is within the range of vacuum-UV light -- so named because while light of that energy can propagate in a vacuum, it is quickly absorbed by oxygen in the air.

Corralling Milk Microbes That Survive Pasteurization

IMG_8272.JPG

Corralling desperados with names like bacillus and paenibacillus will require ingenuity and an arsenal of weapons. These outlaws aren’t rustling cattle—they’re making milk sour and cheese soft and crumbly. For more than a century, milk has been heated to kill any bacteria or pathogens that can affect consumer health and shorten the shelf life of the product. However, microbes-- known as thermoduric--can survive pasteurization, according to South Dakota State University dairy science professor Sanjeev Anand. The Agricultural Experiment Station researcher has begun developing ways to combat heat-resistant microorganisms, a major challenge for the world’s dairy industry. His work is also supported by the Dairy Research Institute and the Midwest Dairy Food Research Center.
