Organic Materials Spotted High Above Titan's Surface
During its closest flyby of Saturn's moon Titan on April 16, the Cassini spacecraft came within 1,027 kilometers (638 miles) of the moon's surface and found that the outer layer of the thick, hazy atmosphere is brimming with complex hydrocarbons. Promising New West Nile Therapy Cures Disease In Mice
West Nile virus has spread from coast to coast, sickened more than 16,000 Americans and killed more than 600. As the virus spread, medical investigators hastened research to develop an effective vaccine or therapy. None currently exist, but a newly published paper by researchers at Washington University in St. Louis points to a promising treatment. This research, published today online by Nature Medicine, was funded in part by NIAID, part of the NIH. Safer Car Controls
The number of electronic components in cars is growing rapidly. To ensure that vehicle electronics will work properly in future despite the overabundance of software and its increasing complexity, researchers are remodeling it and making it even safer. The sight of a shiny new car suggests streamlined high-tech devices. But appearances are deceptive. Under the hood, all is confusion. Around 100 microprocessors control auxiliary functions such as ABS, ESP or the headlight that can shine around corners. Almost as many control units send their commands to fuel injection systems, airbags and other functional modules. World Religion Day
The aim of this day, established by the Baha'i in 1950 and observed on the third Sunday in January, "is to foster the establishment of interfaith understanding and harmony by emphasizing the common denominators underlying all religions."Its site features brief quotations about loving your neighbor from the following religious groups: Hindu, Native American, Jewish, Buddhist, Taoist, Christian, Islam, Sikh, and Baha'i. Note: not available in Spanish or French as the site indicates. University Of Chicago Researchers Find Human Brain Still Evolving
Human evolution, Chicago researchers report, is still under way, in what has become our most important organ: the brain. In two related papers published in Science, they show that two genes linked to brain size are rapidly evolving in humans. The researchers looked at variations of microcephalin and ASPM within modern humans, and found for each gene one class of variants has arisen recently and has been spreading rapidly because it is favored by selection. [Funny] A referee has sent himself off in an English amateur league ma
Andy Wain had to abandon the Sunday league match between Peterborough North End and a Royal Mail side in the 63rd minute after throwing down his whistle and marching up to confront North End's keeper. Turner Prize
Information about "a contemporary art award held at Tate Britain that has provoked debate since its inception in 1984."Features a FAQ, history of the award, profiles of artists nominated for the award with images of their artwork, a quiz, and related background information. From the Tate Britain museum in London. Antidepressants, Exercise, Age, Even Food Intake, Affect Generation Of
Recent research shows that the production of new brain cells may be crucial for antidepressants to be effective and that the medication's effectiveness is strongly influenced by age. What's more, meal frequency, type of food, and physical exercise affect the brain's ability to manufacture these new cells. For the first time in nonhuman primate models, scientists have documented the cause-and-effect relationship between antidepressant drugs and neurogenesis. Doping Technique Brings Nanomechanical Devices Into The Semiconductor
With the help of a device capable of depositing metals an atom at a time in the materials used in computer chips, engineers have successfully blended modern semiconductor technology and nanomachines. Darwin Digital Library of Evolution
This website's goal is to provide the literature of evolution "within a historically and topically coherent structure."The site features the full text of works by Charles Darwin (such as "On the Origin of Species"and images and transcriptions of Darwin's notes for this book), essays on evolutionary science since Darwin and on the cultural implications of the evolutionary theory, and a bibliography. From the library of the American Museum of Natural History.
