...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...

...surveys suggests that the potentially deadly metal is nearly everywhere--and more dangerous than most of us appreciated. Researchers testing birds in the Northeast have found creeping mercury levels in the blood of more than 175 once clean species. Others have found the metal for the first time in polar bears, bats, mink, otters, panthers and more...
...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...
