Oncology: The Long And Winding Trail To Cancer Two new mouse studies have provided insight into the role of the death-inducing protein TRAIL and its receptors in tumor development and metastasis. Binding of TRAIL to its receptors induces the cells expressing the receptors to undergo a form of cell death known as apoptosis. Scientists found that if lymphoma-prone mice were deficient in the TRAIL receptor they developed lymphoma more frequently than TRAIL receptor--sufficient lymphoma-prone mice. Pheromones Identified That Trigger Aggression Between Male Mice This study is the first to identify protein pheromones responsible for the aggression response in male mice. The findings could provide a tool for understanding the neural pathways that play a role in human behavior. A Brief Guide to Meat and Dairy Labels and Their Relevance to Animal W This document provides definitions for terms found on meat and dairy product labels, such as certified organic, certified humane, free-range, cage-free, vegetarian-fed, grain-fed, hormone-free, and pasture-raised and grass-fed.

 Gene Variations Directly Link Inflammation To An Increased Risk For Lu Variations in two genes related to inflammation may be a major risk factor for developing lung cancer, according to a team of scientists from the National Cancer Institute and the University of Texas M. D. Anderson Cancer Center. The effect of these genes is especially strong among heavy smokers, suggesting that the inflammatory response is important in modulating the damage caused by tobacco smoke. Biologists develop efficient genetic modification of human embryonic s Biologists have developed an efficient way to genetically modify human embryonic stem cells. Their approach, which uses bacterial artificial chromosomes to swap in defective copies of genes, will make possible the rapid development of stem cell lines that can both serve as models for human genetic diseases and as testbeds on which to screen potential treatments, they say. [Ironic] Professional beggars prowling about the streets of Moroccan c The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... Research Using Mouse Models Reveals A Novel Key Player In The Initiati An animal model with an inactivating mutation within the mouse equivalent of the APC gene displays very similar pathology as seen in human colon cancers and develop tumor growths called polyps in their colons, eventually leading to death. Inactivating the APC gene was found, as in human cells, to cause the accumulation of a protein called beta-catenin in the nuclei of these cells. Life in Elizabethan England: A Compendium of Common Knowledge, 1558-16 Information about Elizabethan England from a living history perspective.

From a performer at Renaissance fairs. From Bubbles To Capsules Researchers from Japan have developed a clever new technique for the production of silicon dioxide nanocapsules: they start with tiny bubbles of carbon dioxide in a silicon copolymer.
