[Interesting] Underdogs win national underwater robot championship
How four underdogs from the mean streets of Phoenix took on the best from M.I.T. in the national underwater bot championship. Discovery Links Blood Cell Defect To Common Lung Disorder, Leads To No
A persistent scarcity of oxygen in body tissues -- a widespread problem in patients with heart or lung disease -- can create a defect of red blood cells that further exacerbates the condition by constricting blood vessels in the lung, Howard Hughes Medical Institute researchers at Duke University Medical Center have found.
Dusty Old Star Offers Window To Our Future, Astronomers Report
Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust -- a discovery that may provide insights into our own solar system's eventual demise several billion years from now. The results are based on mid-infrared observations made with the Gemini 8-meter Frederick C. Gillett Telescope (Gemini North) on Hawaii's Mauna Kea. The Gemini observations reveal a surprisingly high abundance of dust orbiting an ancient stellar ember named GD 362. Scientists Shed New Light On Behavior Of Shark 'Tweens' And 'Teenagers
Marine biologists have shown that young lemon sharks born in Bimini, Bahamas, tend to stay near their coastal birthplace for many years. Knowledge about these intermediate-aged animals -- the breeders of tomorrow -- has been limited. Thus, tropical island-nations that sacrifice their nursery habitats to coastal development are therefore likely to lose both babies and much older sharks, with potentially dire effects on the surrounding ecosystem. MRI Analysis Could Prevent Brain Damage From Stroke, Study Finds
Greg Albers, M.D., director of the Stanford Stroke Center, and his team report in the November issue of Annals of Neurology that new magnetic resonance imaging techniques can discriminate between stroke patients who are likely to benefit from a stroke medication -- even when administered beyond the currently approved three-hour time window -- and those for whom treatment is unlikely to be beneficial and may cause harm. Answering That Age-old Lament: Where Does All This Dust Come From?
Where does it come from? Scientists are reporting a surprising answer to that question, which has puzzled and perplexed generations of men and women confronted with layers of dust on furniture and floors. Most of indoor dust comes from outdoors. [Ironic] Professional beggars prowling about the streets of Moroccan c
The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... Indian urban wetland heavy metal
A study of heavy metal contaminants in the urban lakes of India, particularly around Bangalore have revealed that attempts at mitigation meant to remove these pollutants have not so far worked and may not be a long-term remedy for the problem. I’ve provided more detail on the analysis in the Atomic ezine on SpectroscopyNOW this [...]Indian urban wetland heavy metal is a post from: Sciencebase Science Blog New Technique Scans Electrical 'Brainscape'
Using hairlike microelectrodes and computer analysis, neurobiologists at Duke University Medical Center have demonstrated that they can see the detailed instant-to-instant electrical "brainscape"of neural activity across a living brain. Cancer Stem Cell Subpopulation Drives Metastasis Of Human Pancreatic C
Scientists have identified a distinct subpopulation of cancer stem cells (CSC) that is responsible for metastasis of a deadly human pancreatic cancer. The research provides insight into the role of CSCs in cancer initiation, progression and metastasis, and suggests new directions for development of more effective therapeutics.
