...largely gone red. Remember the Reading Wars? In the '80s, educators embraced "whole language" as the key to teaching kids to love reading. Instead of using "See Dick and Jane run" primers, grade-school teachers taught reading with authentic kid lit: storybooks by respected authors, like Eric Carle (Polar Bear, Polar Bear). They encouraged 5- and 6-year-olds to write with "inventive spelling." It was fun. Teachers felt creative. The founders of whole language never intended it to displace the teaching of phonics or proper spelling, but that's what happened in many places. The result was a generation...
...protein, we have insight into the function of a protein.” The shape into which a protein folds is determined by the sequence of amino acids that constructs it. The human body has 20 amino acids that can be arranged in any way by the polar forces of water, an abundant compound in cells. Shakhnovich’s model can predict how a certain string of amino acids will fold into a three-dimensional shape with unprecedented accuracy. The team conducted 4,000 simulations that proved to be consistent with experimental results. The biological function of a protein...
...self-appointed world's policeman, to reflect on what constitutes its own values and interests. The policeman should either reflect on the values and interests of the policed world-not necessarily the same as his-or stop being the policeman nobody has asked him to be. The polar opposites of isolationism and interventionism are not the only options. There is also the option of participating in world politics on an equal footing with other nations. Meanwhile, anti-Americanism is unfortunately growing where the U.S. would not expect it. Rainer Lau Brussels...

...global mercury levels rise, more and more species are being affected. A recent study by investigators at Denmark's Natural Environmental Research Institute showed that mercury measurable in the fur of Greenland polar bears is 11 times higher than it was in baseline pelts preserved from as early as the 14th century. This fall the National Wildlife Federation will release a survey of more than 65 recently published studies showing elevated mercury in more than 40 species, many of which had been thought to be in little danger. Some, including common loons and bald eagles, are already showing signs...
