(University of Michigan Health System) As the body creates antibodies to fight invaders, a three-protein DNA repair complex, MRN, is crucial for a normal gene-shuffling process to proceed properly, University of Michigan scientists have found. The discoveries in mice shed light on how B cell lymphoma and some other cancers may begin.

(National Science Foundation) Engineers have developed a new method for creating high-performance membranes from crystal sieves called zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates.

(Michigan State University) While the massive weight loss associated with gastric bypass surgery is beneficial, some patients may face malnutrition, poor wound healing and infection as their immune systems adjust to the extreme decrease in food consumption, according to a Michigan State University researcher.

(American Institute of Physics) Proton therapy -- which uses beams of the subatomic particles to treat cancer -- is a hot topic at this year's American Association of Physicists in Medicine meeting, which takes place from July 26-30 in Anaheim, Calif. Ways to make the technology more effective, cheaper and smaller will be discussed, and news of research on proton computed tomography (proton CT) -- which uses protons to image the body's interior.

(Helmholtz Association of German Research Centres) In honor of scientist and astronomer Nicolaus Copernicus (1473-1543), the discovering team around Professor Sigurd Hofmann suggested the name "copernicium" with the element symbol "Cp" for the new element 112, discovered at the GSI Helmholtzzentrum fur Schwerionenforschung (GSI Center for Heavy Ion Research) in Darmstadt.
