That helps explain why Bolt's legs move fast enough to be a blur. When people run, they are essentially bouncing though the air from one leg to another, says Daniel Lieberman, a professor of biological anthropology at Harvard University who studies how and why the human body looks and works as it does. What determines how fast people go is their stride length - a function of how long the legs are, how powerfully they push off into a stride and how far forward the body jumps - and their stride rate, which is how fast they can propel their legs...
...history in the making--and a strong sense of community pride--explains why you hear many African Americans use the pronoun we to describe Obama's candidacy, as in "When we win ..." Those forces explain why older men who have never become attached to politicians wear hats emblazoned with Obama's name. And why you can find young men sporting hip-hop T shirts that bear the face of Obama instead of Biggie or Tupac. Obama has given millions of black Americans a reason to be proud.

...Despite an unwavering record of opposition to abortion, the Arizona Senator has at times worried religious conservatives by suggesting he would consider a pro-choice running mate - most recently this week while discussing former Pennsylvania governor Tom Ridge. Those comments, combined with McCain's support for stem-cell research, explain the relatively low levels of enthusiasm among Evangelicals for his candidacy. Evangelicals have also been waiting for McCain to speak personally about his own faith. When it comes to discussing religious beliefs, he has a low-key approach more in common with Bush the elder than with the current President...
