Scientists have found that exposure to male perspiration has marked psychological and physiological effects on women: It can brighten women's moods, reducing tension and increasing relaxation, and also has a direct effect on the release of luteinizing hormone, which affects the length and timing of the menstrual cycle.
A technology designed to restore vision in patients suffering from age-related blindness will be demonstrated by a scientist at NASA Ames Research Center in California's Silicon Valley today. Developed by NASA Ames in conjunction with the Stanford University School of Medicine, the "Vision Chip" may help improve age-related macular degeneration, the number one cause of blindness in the elderly. "Nanotechnology that could restore vision is an exciting example of how NASA science and engineering, origially intended for outer space, can return enormous dividends for everyday life here on Earth," said Dr. David J. Loftus, a member of both the Life Sciences Division and the Integrated Product Team on Devices and Nanotechnology at NASA Ames.
The Cassini Imaging Team today is releasing a color composite image of Saturn and its moon, Titan, 20 months before the Cassini spacecraft arrives at the planet. The image is available online from NASA's Jet Propulsion Laboratory at and from the Cassini Imaging Team's University of Arizona site. The image shows the shadow of the planet falling across its famous rings and includes Saturn's largest moon, Titan.
The emergency room may be a prime location for stroke prevention, as well as stroke treatment, a new study finds. That's because patients with a high stroke risk due to heart rhythm problems are likely to turn up at the ER for symptoms of their irregular heartbeat, giving doctors a chance to make sure they're on the best drugs to prevent a stroke.
In an embryo, certain genes must turn on to, for example, tell cells to develop into a limb. But just as importantly, the genes must then turn off, or go silent, to prevent abrnomral growth. How the genes do that gets some new light in research released out of North Carolina.
As tobacco companies campaign to promote smokeless tobacco as a safer alternative to cigarettes, many smokers who take up snuff in an effort to quit instead end up using both products, according to a Florida researcher. Further, nonsmokers who use snuff are more likely than those who don't to eventually begin smoking.
