...field of biological aging has in recent years focused on the long molecules of DNA contained in human cells called chromosomes. All chromosomes have protective caps at either end called telomeres. Each time a cell replicates itself (as it does before it dies), the telomeres shorten, like plastic tips fraying on the end of shoelaces. Shortened telomeres have been linked to a host of age-related illnesses such as heart disease and certain cancers. (Scientists have yet to study whether telomeres influence a person's appearance.) Last year's Nobel Prize for Medicine was awarded to three American scientists...
...better understand the aging discrepancy, a team of researchers in Britain and the Netherlands scanned more than 500,000 genetic variations across the human genome. Using a population of nearly 12,000, they then attempted to pinpoint a genetic link to telomere length. (See how to prevent illness...
Protecting tigers in captivity is one thing, but the bigger challenge is restoring their numbers in the wild. Deforestation and the ballooning human populations in Asia have chased tigers out of their native habitat. Yet the health of the tiger means the health of the planet. "If there is a tiger in the forest, it's a sign that the forest and the other animals in it are healthy," says Varma. "Tigers are the face of biodiversity." Hopefully, then, 2010 will truly be the tiger's year...
...civilians to leave Marja until the fighting was over and the town had been re-captured. Over 100,000 Pashtuns live around Marja, but only several thousand fled. Fleeing families told journalists on the road that the Taliban had ordered Marja's people to stay behind, giving them a human shield to hide behind as the NATO forces closed in. Others said their relatives could not leave because the roads outside their homes were too heavily mined...
...Indeed, the proposals put forward by Prime Minister Francois Fillon this week to bolster patriotism are hardly revolutionary in scope. They include a requirement for schools to fly the French flag (most already do) and for each classroom to display the Universal Declaration of Human Rights (ditto). Authorities also called for naturalized foreigners to meet unspecified linguistic and integration requirements and instructed schools to issue "Young Citizen's Logs" to children in which they can record their civic actions.
