Procedures used to obtain and examine tissue for cancer diagnosis are prone to error that frequently results in harm, according to a new study. Agency for Healthcare Research and Quality-funded researchers say that a governmentally mandated error detection method that involves the review of patient specimens, when patients have two or more specimens from the same body site, found up to 12 percent of reviewed specimen pairs had an erroneous diagnosis. However, pathologists failed to agree on the cause of most of these errors.
Tagging Pathogens With Synthetic DNA 'Barcodes'
A new technology developed at Cornell University can identify genes, pathogens, illegal drugs and other chemicals of interest by tagging them with color-coded probes made out of synthetic DNA. Engineering The 'Super Enzyme' -- A Potential New Weapon Against Heart

A five-minute eye exam might prove to be an inexpensive and effective way to gauge and track the debilitating neurological disease multiple sclerosis, potentially complementing costly magnetic resonance imaging to detect brain shrinkage -- a characteristic of the disease's progression. Yale Researchers Make Cell Biology Quantitative
Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, two basic hurdles for studying biology quantitatively. The assay is accurate and effective whether the molecules are spread out or concentrated in particular parts of the cell. Sperm Trading Can Resolve Hermaphrodite Mating Conflicts
By directly manipulating mating performance in a tropical sea slug, Chelidonura hirundinina, researchers of the University of Tübingen have now shed light on the bizarre reproductive conflicts encountered by hermaphroditic animals. In some hermaphroditic species, such as C. hirundinina, mating partners may insist on copulating as a "male,""female,"or both, resulting in unique biological conflicts over gender. New Treatments For Common Vaginal Infection Being Studied
