Improved Molecular Switch Could Serve As Sensor, Medical Tool
Improving significantly on an early prototype, Johns Hopkins University researchers have found a new way to join two unrelated proteins to create a molecular switch, a nanoscale "device"in which one biochemical partner controls the activity of the other. Lab experiments have demonstrated that the new switch performs 10 times more effectively than the early model and that its "on-off"effect is repeatable.

Adults with and without diabetes have benefited similarly from the decline in cardiovascular disease (CVD) rates over the last several decades, according to a study funded by the National Heart, Lung, and Blood Institute (NHLBI). However the study, which is published in the November 24 issue of the Journal of the American Medical Association, found that people with diabetes still have twice the risk of cardiovascular disease compared to people without diabetes. Two Drugs Equally Effective For Heart Patients Undergoing Angioplasty,
In lifesaving procedures to open blocked heart arteries a key question has persisted for years: Is use of the more expensive drug, abciximab, justified over use of the less-expensive eptifibatide? A recent study found no significant difference between the drugs in the length of hospital stay or in the rate of cardiovascular event rates. What Makes The Brain Tick, Tick, Tick: Researchers Gaining New Insight
The brain is a "time machine,"assert Duke neuroscientists Catalin Buhusi and Warren Meck. And understanding how the brain tracks time is essential to understanding all its functions. The brain's internal clocks coordinate a vast array of activities from communicating, to orchestrating movement, to getting food, they said. FireWire vs High-Speed USB
Compares and contrasts FireWire (officially known as IEEE 1394, and as i.Link by Sony) and high-speed USB (universal serial bus) technologies for connecting peripheral devices to a computer. Provides a brief history of the technologies, a chart showing the pros and cons of each, system requirements, and related information. From the Australian Consumers' Association, an independent consumer research organization. Human Testis Harbors HIV-1 In Resident Immune Cells
Researchers have demonstrated HIV replication within resident immune cells of the testis, providing an explanation for the persistence of virus in semen even after effective highly active antiretroviral therapy. The related report by Roulet et al., "Susceptibility of human testis to human immunodeficiency virus-1 infection in situ and in vitro,"appears in the December issue of the American Journal of Pathology. Mercury In Atmosphere Could Be Washed Out More Easily Than Earlier Bel
New University of Washington research suggests mercury can be carried long distances in the atmosphere, combining with other airborne chemicals to form compounds that are much more water-soluble and so more easily removed from the air in rainfall.
