Carbon Nanoparticle Could Keep the Flow Going

One of the biggest costs involved in treating water is cleaning the filters that purify the water. Microbes in the water agglomerate on the surface of the filters in a process called biofouling. This clogs the filters, requiring costly cleaning. New research at Duke University could help prevent this clogging through the use of a carbon nanoparticle called the "buckyball."

New "Functional" Yogurt Proves Promising in Fighting Ulcers and Gastritis

The results from a recent clinical study suggested the promising ability of "functional" yogurts that have been strengthened with antibodies to prevent and treat stomach ulcers and gastritis. The study was conducted by a group of Japanese researchers at Kyoto Women's University and the results were recently presented at the 237th meeting of the American Chemical Society at Salt Lake City, Utah, USA.

Acetylaldehyde-Cancer Risk Assessment

Researchers at the Centre for Addiction and Mental Health (CAMH) in Toronto and Chemical and Veterinary Investigation Lab in Karlsruhe (CVUA), Germany stated in a review published online in Addiction on 17th March 2009 that current risk assessments of acetaldehyde-induced cancer do not accurately portray risks associated with the disease. They also stated that alcoholic beverages carry the highest risk of acetaldehyde-induced cancer.

Is Nature Colorblind?

Why do domesticated dogs come in so many different shapes and colours, while wolves appear to be much similar to each other? Scientists have long theorized that humans had something to do with this increased phenotypic diversity within the species, and now researchers from the Universities of Uppsala and Durham have confirmed one piece of the puzzle in a study published in PLoS Genetics in March.
