New obesity staging system may help doctors measure up

Tweet

A new system proposed by Canadian and US obesity researchers may provide another weapon in the battle against obesity. University of Alberta obesity expert Dr. Arya Sharma, along with a researcher from Northwestern University in Chicago, Illinois, has proposed a classification system to help doctors assess and treat overweight patients.

Google "Edward the Confessor" and you'll get page after page of links to biographies of this 11th-century English king, to Westminster Abbey, which he founded and where he is buried, and to the Magna Carta, which was partly inspired by laws enacted during his 24-year reign.

But a completely digitized manuscript of the oldest surviving Anglo-Norman history of the king does not turn up — at least on the first 20 search pages — even though Cambridge University painstakingly scanned the sumptuously illustrated manuscript in 2003.

Biofuels can provide viable, sustainable solution to reducing petroleum dependence

LIVERMORE, Calif. — An in-depth study by Sandia National Laboratories and General Motors Corp. has found that plant and forestry waste and dedicated energy crops could sustainably replace nearly a third of gasoline use by the year 2030.

The goal of the "90-Billion Gallon Biofuel Deployment Study" was to assess whether and how a large volume of cellulosic biofuel could be sustainably produced, assuming technical and scientific progress continues at expected rates. The study was conducted over a period of nine months.

Research highlights potential for improved solar cells

Tweet

LOS ALAMOS, New Mexico, February 10, 2009—A team of Los Alamos researchers led by Victor Klimov has shown that carrier multiplication—when a photon creates multiple electrons—is a real phenomenon in tiny semiconductor crystals and not a false observation born of extraneous effects that mimic carrier multiplication. The research, explained in a recent issue of Accounts of Chemical Research, shows the possibility of solar cells that create more than one unit of energy per photon.

Study: Fluid buildup in lungs is part of the damage done by the flu

Tweet

COLUMBUS, Ohio – In a fight against respiratory infections, the body typically produces a little fluid to help the lungs generate a productive cough. But new research suggests that the influenza virus can tip the balance toward too much fluid in the lungs, interfering with the supply of oxygen to the rest of the body.
