Novel Genetics Research Advances Possibility Of HIV Vaccine
A pioneering collaborative study has discovered how the HIV virus evades the human body's immune system. The researchers used highly computer-intensive, cutting-edge statistical research methods to investigate how the HIV virus mutates to escape the body's immune system. Zune's Manufacturer: Toshiba?
Documents on the FCC's website indicate that Toshiba is actually manufacturing Microsoft's Zune MP3 player, and offer new details about the device's wireless features and color options. In Listening Post. LibraryLaw Blog: How Does California's New Anti-spyware Law Affect Lib
Brief information about the Consumer Protection Against Computer Spyware Act that went into effect in California on January 1, 2005. Includes a link to the text and to objections to the law raised by privacy advocates. From librarian and lawyer Mary Minow. Small Variations In Genes Can Determine Risk Of Developing Breast Canc
A woman's risk of developing breast cancer is due in part to a group of very small variations in genes which code for a cell's estrogen receptors, according to a new study. Specialized Bath Products For Allergic Eczema Of 'Questionable'Value
Specialized bath products to relieve the symptoms of allergic (atopic) eczema are of "questionable"value, according to new research. UK's National Health Service forks out more than £16 million a year on bath emollients, equivalent to almost 40 percent of the total cost of eczema treatments prescribed for preschool children, says DTB. Bacteria Are Key To 'Green' Plastics, Drugs
Commerical trials are underway in Kansas on a "green"method of making succinate, a key ingredient of many plastics, drugs, solvents and food additives. Scientists are using a genetically modified bacteria that metabolizes glucose from grain sorghum and produces almost pure succinate. Finding clean, renewable production methods for succinate and other high-use chemicals is a high priority of the U.S. chemical industry, the Department of Energy and the U.S. Department of Agriculture. Pancreatic Cancer Fights Off Immune Attack
Scientists have discovered that pancreatic cancer attracts regulatory T cells, which suppress the activity of immune cells. In this way, the tumor might escape its destruction by the immune system. The ability to discriminate between friend and foe or between "self"and "foreign"is vital for a functioning immune system. There are numerous protective mechanisms at work to save the body's own tissue from attacks by misguided immune cells. A pivotal role is played by regulatory T cells (Treg cells), which prevent immune reactions against the body's own structures by suppressing the aggressiveness of particular immune cells called T helper cells. New Virtual Reality Chair To Explore Frontier Of 'Telepresence'
The closest many of us have come to imagining virtual reality is the holodeck, a fantasy playground featured on the television series Star Trek. Such flights of fancy are no longer the stuff of science fiction, however. Computer scientists at the U of A have already created technology allowing people to sit across from three-dimensional recreations of each other, even though in reality they may be thousands of miles apart. New Drug Makes Weight Loss Safer, Study Suggests
More than 60 percent of American women are overweight, with nearly a third falling into the category of obese and at greater risk of cancer, heart disease and diabetes. Until now, there has been no safe, long-term medical remedy that tackles unwanted weight gain. Now, a well-known drug used to treat vertigo has been adapted for a new purpose: to treat obesity. The vertigo drug has been in use for 30 years and has an excellent safety profile, according to the researchers. Mathematician Untangles Legendary Problem
Karl Mahlburg, a young mathematician, has solved a crucial chunk of a puzzle that has haunted number theorists since the math legend Srinivasa Ramanujan scribbled his revolutionary notions into a tattered notebook.
