Alberta to review rules on water in oil sands
September 1, 2010
Alberta Premier Ed Stelmach said Wednesday his government will rewrite the rules governing water in the oil sands region should the province's own environmental data prove faulty when compared to a recent critical study out of the University of Alberta.
The perfect nanocube: Precise control of size, shape and composition
September 1, 2010
Researchers at the National Institute of Standards and Technology have developed a simple process for producing nanocrystals that will enable studies of certain physical and chemical properties that affect how nanoparticles interact with the world around them.
Old Star's Super-Hot Water Vapor Surprises Scientists
September 1, 2010
Scalding hot water vapor has been discovered in the atmosphere of an aging star, surprising scientists who thought the chemistry of such stars would forbid it.
Nobel Peace Prize winner hosts dinner
September 1, 2010
As Leonard Cohen would put it, it seems so long ago. Looking back to those heady days for the new U.S. Administration, it's inconceivable that any serious person could have defended the Nobel committee's choice of Mr.

New Light On The Mechanism Of Parkinson's Disease
A significant number of Parkinson's disease patients have a mutation of the enzyme Leucine-Rich Repeat Protein Kinase 2 (LRRK2, also known as dardarin). However, little is understood about how it is regulated or functions...
Microsoft Excel-based Algorithm Predicts Cancer Prognosis
Using readily available computer programs, researchers have developed a system to identify genes that will be useful in the classification of breast cancer. The algorithm, described in BioMed Central's open access Journal of Experimental & Clinical Cancer Research will enable researchers to quickly generate valuable gene signatures without specialized software or extensive bioinformatics training...
Fisher Scientists Discover Protein That Fuels Alzheimer's Disease, Promising New Treatments Expected
Researchers at the Fisher Center for Alzheimer's Disease Research laboratory published "Gamma-secretase Activating Protein is a Therapeutic Target for Alzheimer's Disease" in Nature online. Drs. Gen He (lead author) and Paul Greengard have discovered a protein that stimulates the production of beta-amyloid, and therefore represents a major new advance in Alzheimer's disease research...
Nanobiotechnology To Fight Cancer And Other Illnesses
Two new groundbreaking scientific papers by researchers at UC Santa Barbara demonstrate the synthesis of nanosize biological particles with the potential to fight cancer and other illnesses. The studies introduce new approaches that are considered "green" nanobiotechnology because they use no artificial compounds...
Battling Cancer: New Infrared Light May Open New Frontier In The Fight
A "game-changing" technique using near infrared light enables scientists to look deeper into the guts of cells, potentially opening up a new frontier in the fights against cancer and many other diseases. University of Central Florida chemists, led by Professor Kevin Belfield, used near infrared light and fluorescent dye to take pictures of cells and tumors deep within tissue...

Colors of Chemistry March 2010
Each year, the Chicago River is dyed green to celebrate Saint Patrick's Day in downtown Chicago. Members of the Journeymen Plumbers Local Union 130 are responsible for mixing dye into the river, but the brilliant green hue can be credited to the work of German chemist and Nobel Prize winner Adolf von Baeyer. In 1871, Baeyer was the first to synthesize fluorescein, the xanthene dye used for the inaugural dyeing of the river in 1961.
