The Strange Case of Solar Flares and Radioactive Decay Rates 408

DarkKnightRadick writes "Current models for radioactive decay have been challenged by, of all sources, the sun. According to the article, 'On Dec 13, 2006, the sun itself provided a crucial clue, when a solar flare sent a stream of particles and radiation toward Earth. Purdue nuclear engineer Jere Jenkins, while measuring the decay rate of manganese-54, a short-lived isotope used in medical diagnostics, noticed that the rate dropped slightly during the flare, a decrease that started about a day and a half before the flare.' This is important because the rate of decay is very important not just for antique dating, but also for cancer treatment, time keeping, and the generation of random numbers. This isn't a one time measurement, either. 'Checking data collected at Brookhaven National Laboratory on Long Island and the Federal Physical and Technical Institute in Germany, they came across something even more surprising: long-term observation of the decay rate of silicon-32 and radium-226 seemed to show a small seasonal variation. The decay rate was ever so slightly faster in winter than in summer.'"

Academic Says We Should Give Up on Correct Spelling 30

Fed up with his students inabillity to spel korrectly, Ken Smith, a criminology lecturer at Bucks New University, has purposed an inovative solution, not caring. "Instead of complaining about the state of the education system as we correct the same mistakes year after year, I've got a better idea. University teachers should simply accept as variant spelling those words our students most commonly misspell.", Ken wrote in the Times Higher Education Supplement. Some of the new wurds that Ken thinks we shood axxept include: "ignor," "occured," "thier," "truely," "speach", "twelth", "misspelt", and "varient".
