...speed isn't a new concern for Google - the company says they've begun taking loading times into account as part of search rankings, and speed was a selling point behind the development of its increasingly popular Google Chrome Web browser. But these are all innovations on the software end; this latest plan goes after the networks themselves. The U.S. is ranked 12th in the world in broadband speed and 15th in the world for broadband penetration. Not bad numbers, but U.S. providers are only now working on the next generation of broadband access, limited to 100 Mbps. By contrast...
...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...
...unexpected threats to the tiger comes here in the U.S., where there are more tigers kept in private captivity then there are surviving wild animals left in the world.

The crowd gave the small clutch of Georgian athletes, clearly saddened and wearing black armbands in honor of their fallen teammate, a classy standing ovation as they entered the arena. Toward the end of the evening, International Olympic Committee president Jacques Rogge said a few words in Kumaritashvili's honor before the torch was lit: he genuinely seemed to be struggling...
Jonathan will need more than luck to fix Nigeria. His most pressing job is to re-energize the peace process in the oil-rich southern Delta region. Talks to end the decade-old conflict with Delta rebels - they say they are fighting for a fairer share of the revenues from their land, and are also angry about the pollution caused by oil spills - was a central thrust of Yar'Adua's early presidency. Six months ago, Yar'Adua persuaded the rebels to agree to a ceasefire and mass disarmament in return for an amnesty, a small monthly stipend...
