Mike sends in the story of a new fingerprint technology with interesting potential for both crime detection and rights violations; there are also intriguing possibilities in fighting cancer. "Using a variation of mass spectrometry called 'desorption electrospray ionization' or 'Desi,' a fingerprint can identify what the person has been touching — drugs, explosives, or poisons, for example. Writing in the Friday issue of the journal Science, R. Graham Cooks, a professor of chemistry at Purdue University, and his colleagues describe how the technique could find a wider application in crime investigations. As it becomes cheaper and more widely available, the Desi technology has potential ethical implications, Cooks said. Instead of drug tests, a company could surreptitiously check for illegal drug use of its employees by analyzing computer keyboards after the employees have gone home, for instance."

netbuzz writes "A new survey finds that more than half of K-12 students believe that educational video games in school would help them learn (no surprise), although only 15% of teachers and 19% of parents agree. Adults might not want to scoff, however, because 11% of teachers are already using video games in class and they report great results. 'Only 3% of elementary school students say they do not play video games of any kind. Students surveyed say learning via video games would help them better understand difficult concepts, become more engaged in the subject matter and practice skills. There's no mention of the games being fun, but that goes without saying.'"
