Acne Medication Associated With Abnormal Blood Test Results
Elevated cholesterol levels and liver enzyme levels appear to be more common than previously thought among patients taking the acne medication isoretinoin, including those who had normal blood test results before beginning therapy, according to a report in the August issue of Archives of Dermatology, one of the JAMA/Archives journals. Gene Discovery Reveals Critical Protein's Function In Hearing
Discovery of a deafness-causing gene defect in mice has helped identify a new protein that protects sensory cells in the ear, according to a new study. The mutated gene fails to produce normal claudin-9 protein, which, the scientists showed, is needed to maintain the proper distribution of potassium in the inner ear. Researchers Find A Mutation In LRRK2 Gene Causes Parkinson's Disease I
Neuroscientists at Mayo Clinic in Jacksonville, Fla., leading a team of researchers in the United States and Europe, have discovered that a novel mutation in the recently identified LRRK2 gene causes parkinsonism in several North American and European families. [Scary] Detroit Has the Worst Fans
Indiana's Ron Artest and Stephen Jackson charged into the stands and fought with fans in the final minute of their game against the Detroit Pistons on Friday night, forcing an early and ugly end to the Pacers' 97-82 win. Gut Research Yields New Anti-cancer Approach
Researchers believe they have discovered by chance a new way to fight colorectal cancer, and potentially cancers of the esophagus, liver and skin. Early work shows that a group of compounds called peroxisome proliferator-activated receptor-gamma (PPARgamma) inhibitors may act through some of the same mechanisms as the blockbuster chemotherapy Taxol, but with key differences. Coal: The Other Alt Fuel
Coal can be converted into diesel fuel for vehicles and gas for power plants, but the environmental penalty is steep. In Autopia. Squeezing Light Into Much Tighter Spaces Than Previously Believed Poss
Scientists have made a breakthrough that could change the world's thinking on what light is capable of. The researchers have discovered that light within optical fibers can be squeezed into much tighter spaces than was previously believed possible. Rockefeller Scientists Show That MicroRNAs Play An Essential Role In T
The beauty of fruit flies as a scientific model system is that they are easy to manipulate and they give results fast. New research from Ulrike Gaul, Ph.D., at Rockefeller University, takes advantage of these characteristics to show that microRNAs are powerful regulators of fundamental processes including cell survival and nerve and muscle development. Certain microRNAs are conserved between flies and humans, so that these findings may shed light on how different human genes are controlled. AK-47: An Assault Rifle for Everyman

 Engineers Discover Why Toucan Beaks Are Models Of Lightweight Strength
In a paper to be published Dec. 1 in Acta Materialia, researchers report that the secret to the toucan beak's lightweight strength is an unusual bio-composite. The interior of the beak is rigid "foam"made of bony fibers and drum-like membranes sandwiched between layers of keratin, the protein that makes up fingernails, hair, and horn.
