POPSHow your inner athlete makes you smarter
also from article: Even when we are sitting or lying down, our bodies send our brains regular updates about how our limbs are positioned. When we, say, stand and begin walking, these electric messages need to be sent more often. (Knee is bent, straight, bent, straight ...) Move fast enough and the electrical activity doesn't have time to dissipate between each message. It begins building up in the brain and eventually triggers a release of chemicals called growth factors. Growth factors are like manna for neurons. "They make neurons stronger, healthier and improve their ability to learn," Cotman said. In the presence of growth factors, new neurons are born and old ones sprout, grow and form better connections with each other. Blood vessels blossom along side the neurons, giving them quick access to glucose and other nutrients. All this, in turn, improves our ability to think, learn and remember. As Cotman said, exercise "builds the pipes" for improved cognition.

POPSChildren's books become ideological battleground in Sweden Both Tomicic and Salmson, however, dismiss the criticism as "cultural elitism," pointing out that they have received an overwhelmingly positive response from parents. "It is perfectly possible to make good literature that takes these issues into consideration," Tomicic says, pointing out that "we have good authors and illustrators and we insist there is a good story.

One of Olika's illustrators, Per Gustavsson, has publicly criticised the publisher's request to change the colour of a girl's T-shirt from its original pink in one book, while questions have been raised about the interest of portraying homosexual parents in another book when the fact is not important to the story line. "We are trying to break a pattern," Tomicic responds, insisting that it is important to show children that there are many natural alternatives to traditional ways of describing gender roles, including the colours girls and boys wear, and family structur

POPSKenyan children abducted and terrorized- child soldiers and land conflicts ENDING OF ARTICLE: In the meantime, Kenya's land issues remain unresolved. And the powerful politicians that villagers and former fighters say lead the militia remain free. "The conflict in Mount Elgon is but the worst example of the poisonous relationship between Kenyan politics, land grievances and violence," said Ben Rawlence of New York-based Human Rights Watch. If the children are released, some can trace their families. Others have no parents left after murders by either the militia or the military. Peace and justice are far beyond the hopes of most families. Mothers say their ears still strain beyond the drumbeat of rain on a tin roof or wind rustling through cornstalks for the sounds of a vanished child's voice. Some scarred children will eventually limp home along the winding mountain trails. Others never will.
