Fine-Structure Constant Maybe Not So Constant 105

Kilrah_il writes "The fine-structure constant, a coupling constant characterizing the strength of the electromagnetic interaction, has been measured lately by scientists from the University of New South Wales in Sydney, Australia and has been found to change slightly in light sent from quasars in galaxies as far back as 12 billion years ago. Although the results look promising, caution is advised: 'This would be sensational if it were real, but I'm still not completely convinced that it's not simply systematic errors' in the data, comments cosmologist Max Tegmark of MIT. Craig Hogan of the University of Chicago and the Fermi National Accelerator Laboratory in Batavia, Ill., acknowledges that 'it's a competent team and a thorough analysis.' But because the work has such profound implications for physics and requires such a high level of precision measurements, 'it needs more proof before we'll believe it.'"

WrongSizeGlass writes "The L.A. Times is reporting that Santa Clara County officials have voted to ban toys and other promotions that restaurants offer with high-calorie children's meals. 'This ordinance prevents restaurants from preying on children's love of toys' to sell high-calorie, unhealthful food, said Supervisor Ken Yeager, who sponsored the measure. 'This ordinance breaks the link between unhealthy food and prizes.' Supervisor Donald Gage, who voted against the measure, said, 'If you can't control a 3-year-old child for a toy, God save you when they get to be teenagers.' The vote was 3 - 2 in favor of the ban."
