Insulin Levels Drop With Progression Of Alzheimer's Disease, Linked To
Researchers at Rhode Island Hospital and Brown Medical School have discovered that insulin and its receptors drop significantly in the brain during the early stages of Alzheimer's disease, and that levels decline progressively as the disease becomes more severe, leading to further evidence that Alzheimer's is a new type of diabetes. They also found that acetylcholine deficiency, a hallmark of the disease, is linked directly to the loss of insulin and insulin-like growth factor function in the brain. Popular Insecticide Detected In Suburban Stream Beds
For the first time, researchers have detected high concentrations of pyrethroids, a popular insecticide, in suburban stream sediments, raising concerns about its effects on aquatic life. The finding, by Donald Weston of the University of California, Berkeley and others, appears in the Dec. 1, issue of the American Chemical Society's journal, Environmental Science &Technology. Apple Makes iTunes the Activation Agent for New iPhone
Rumor has it that Apple's introducing a new way to buy a mobile phone -- pleasant and easy, with all the pleasure of private unboxing in true Apple tradition. Lighting The Way Toward Understanding Nitric Oxide's Role Inside Livin
Eavesdropping on the behavior of nitric oxide (NO) in parts of the body ranging from the penis to the brain is important to solving the mysteries of how this small molecule plays such a big role in conditions ranging from male sexual function to communication among nerves. Salmon Survival, Cleaner Hydropower Focus Of ORNL Research
A new advanced turbine being tested at Wanapum Dam in Washington state produces nearly 5 percent more power, but before more are installed researchers at Oak Ridge National Laboratory are getting input from several thousand fish. New Method For Quantum Cooling Discovered
Physicists at The University of Texas at Austin have discovered a new technique for cooling atoms and molecules that will allow them to study quantum physics more effectively with a greater variety of particles. The researchers have found a way to use lasers to form walls that allow atoms and molecules to pass through in one direction, but do not allow them to return. Lab-on-a-chip Could Speed Up Treatment Of Drug-resistant Pneumonia
A new lab-on-a-chip can identify single bacterial cells for the most common cases of drug-resistant pneumonia, cutting down the wait from days to hours for identifying the particular strain and treating it. Learning To Fight An Adversary That Won't Stay Down
"New biomolecular technologies have largely failed to deliver the hoped-for knockout punch breakthrough against the defences of disease-causing bacteria,"says a leading Canadian specialist in antibiotic resistance. New Device For Finding Bacteria Developed
Infection-causing bacteria can't hide anymore. Researchers have just developed a new diagnostic tool to detect them. A patent is pending for the new Lateral Flow Assay device to detect the microorganisms bound together in a protective wall, known as biofilms, which attach to inanimate substances, such as rocks in streams or catheters in humans, or to living tissue such as human heart valves and bone. Researchers Find High Levels Of Potentially Toxic Heavy Metals In Herb
According to a study to appear in the Dec. 15, 2004 issue of the Journal of the American Medical Association (JAMA), one of five Ayurvedic herbal medical products (HMPs), produced in South Asia and available in Boston area stores, contains potentially harmful levels of lead, mercury, and/or arsenic.
