Researchers Create New Super-thin Laser Mirror Engineers at UC Berkeley have created a new high-performance mirror that packs the same 99.9 percent reflective punch as current high-grade mirrors, but in a package that is 20 times thinner and easier to manufacture. The new mirror could dramatically improve the design and efficiency of next generation laser optics for such devices as high-definition DVD players, computer circuits and laser printers. Quality Counts 2007: From Cradle to Career: Connecting American Educat Collection of articles and data from January 2007 "track[ing] state efforts to create seamless education systems from early childhood to the world of work."Features articles on topics such as "Gauging Student Learning"and "Linking Learning to Earning,"and the "Chance for Success Index,"which provides state-by-state data on 13 individual indicators (such as family income and preschool enrollment). From Education Week magazine with support from the Pew Center on the States. Bugs, Even The 'Bad' Ones, Can Be Educationally Beneficial, New Book S We have much to learn from bad bugs, according to Gilbert Waldbauer, whose book "Insights From Insects: What Bad Bugs Can Teach Us"was published today (Prometheus Books). Antidepressant Found To Extend Lifespan In C. Elegans The antidepressant mianserin can extend the lifespan of the the roundworm by about 30 percent. The drug may act by mimicking the effects of caloric restriction, which has been shown to retard the effects of aging in a variety of animals ranging from worms and flies to mammals. Are films ferroelectric? Films as thin as you like [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. Inconsistencies With Neanderthal Genomic DNA Sequences The sequencing of Neanderthal nuclear DNA from fossil bone held promise for finally answering the question of whether the Neanderthals are ancestors of ours. However, two recent studies came to very different conclusions regarding the ancestral role of Neanderthals. New Therapy Could Preserve Vessel Function After Heart Attack Scientists have identified the process that causes blood vessels to constrict during and after a heart attack. They've also demonstrated that delivering a vital molecule that is depleted during this process directly to those blood vessels can reverse damage and help restore blood flow. The medical researchers say these findings have the potential to improve outcomes for patients with acute coronary episodes related to ischemia, and to ameliorate the restriction of blood supply to the heart. Parents Support Genetic Testing, DNA Biobanks, Study Finds Genetic testing holds great promise for the future. Information generated by genetic testing may provide information that leads to new treatments for common diseases such as heart disease and diabetes. But how do parents really feel about testing their child's DNA for diseases that may not have an available treatment, and how willing are they to store their child's DNA in a government biobank to help yield new strategies for disease treatment and prevention in the future? Solving Solar System Quandaries Is Simple: Just Flip-flop The Position The planets in our solar system weren't always in the order they are today. Four billion years ago, early in the solar system's evolution, Uranus and Neptune switched places, according to new work by a Arizona State University researcher, who based this conclusion on calculations of the surface density of the solar nebula. The solar nebula is the disk of gas and dust out of which all of the planets formed.
