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.'"

A study authored by Christopher Nave, a doctoral candidate at the University of California, says that our personalities stay pretty much the same from early childhood all the way through old age. From the article: "Using data from a 1960s study of approximately 2,400 ethnically diverse schoolchildren (grades 1 - 6) in Hawaii, researchers compared teacher personality ratings of the students with videotaped interviews of 144 of those individuals 40 years later. They examined four personality attributes - talkativeness (called verbal fluency), adaptability (cope well with new situations), impulsiveness and self-minimizing behavior (essentially being humble to the point of minimizing one's importance)." This must explain my overriding need to be first captain when we pick kickball teams at the office.
