Depression Linked To Bone-thinning In Premenopausal Women
Even in young women, depression is as potent a risk factor for osteoporosis as are low calcium intake, smoking, and lack of exercise, researchers have found. Imbalances in the immune system appear to be involved. Depression generally isn't on clinicians'radar screens as a risk factor for bone-thinning -- but it should be. RFID for chemicals
A new type of radio frequency identification (RFID) sensor for gaseous molecules has been created based on a standard RFID tag coated with a chemically sensitive film at low cost. The use of multivariate analysis allows these new RFID sensors to be used to identify and quantify vapours important to industrial, in health, law enforcement, [...] Neural Cell Transplants Fight Immune Attack In Mice With Multiple Scle
The July 14, 2005 Nature publishes unexpected results in which adult mouse neural stem cells injected into mice with multiple sclerosis (MS) suppressed immune attacks, suggesting resident neural stem cells may not only serve as repair cells, but may also protect the brain from inflammation. The study was co-funded by the National MS Society. Further research is needed to confirm these results and translate into ways to protect and repair brain tissues in people with MS. 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. Reduced Fish Stocks Linked To Increased Bushmeat Trade, Wildlife Decli
Declining fish stocks are fuelling a multibillion-dollar bushmeat trade in West Africa. It's a trend that is threatening the survival of dozens of wildlife species, and EU fishing agreements with African nations may be part of the problem, says a group of international researchers. Nutrition Model Stresses Positive Experience Of Eating
Enjoying the eating process without focus on dietary restrictions may be key to managing weight and staying healthy, according to researchers who have unveiled a new and effective model for managing eating. New NIST Method Improves Accuracy Of Spectrometers
Measurements of the intensity of light at different wavelengths can be made more accurately now, thanks to a new, simple method for correcting common instrument errors. The new method, developed by researchers at the National Institute of Standards and Technology (NIST), will benefit fields such as color measurement, lighting development, remote sensing, biotechnology and astronomy. Messenger: Mercury Surface, Space Environment, Geochemistry, and Rangi
Information about the "NASA Discovery mission to conduct this orbital study of the innermost planet."Messenger launched in August 2004. It should be "in position to enter Mercury orbit in March 2011."The site provides a FAQ, an overview of the mission, status reports, facts about the planet Mercury, information for students and teachers, related links, and more. From John Hopkins University Applied Physics Laboratory (JHU/APL). 'Electric' Fish Shed Light On How Brain Directs Movement
Scientists have long struggled to figure out how the brain guides the complex movement of our limbs, from the graceful leaps of ballerinas to the simple everyday act of picking up a cup of coffee. Using tools from robotics and neuroscience, researchers have found some tantalizing clues in an unlikely mode of motion: the undulations of tropical fish. Saving Disappearing Marine Resources Needs Both Scientific And Indigen
Scientific and indigenous knowledge must join together to better manage disappearing marine resources in developing countries, such as shark, trochus, and sea cucumber stocks on the islands to Australia's north. That's the view of Dr Simon Foale, a researcher with the ARC Centre of Excellence for Coral Reef Studies and James Cook University, who studies coral reef fisheries in the Solomon Islands as they undergo rapid and dramatic change.
