More than 500 workers at Japan's, Keihin Electric Express Railway, must have their faces scanned each morning to determine their optimum smile. The "smile scan" analyzes a smile based on facial characteristics, from lip curves and eye movements to wrinkles. After the program scans you, it produces a smile rating that ranges from zero to 100 depending on the estimated potential of your biggest smile. If your number is sufficient, you can go about your day grinning like a maniac. If your smile number is too low the computer will give you a message such as, "lift up your mouth corners" or "you still look too serious." Every morning employees receive a printout of their daily smile which they are expected to keep with them throughout the day.

But if the MAGIC gamma-ray telescope team's interpretation is correct, then a delay in the arrival of higher-energy gamma rays could point to a breakdown of relativity theory. A type of 'quantum lensing effect' is postulated to cause the delay, which is approximately four minutes over a half-billion year journey." Ars's writeup is a little more fleshed-out than the Scientific American blog posting.

I*Love*Green*Olives writes to tell us the Toledo Blade is reporting that State officials have rubber-stamped a "civil-registry" that would allow accused sex offenders to be tracked with the sex offender registry even if they have never been convicted of a crime. From the article: "A recently enacted law allows county prosecutors, the state attorney general, or, as a last resort, alleged victims to ask judges to civilly declare someone to be a sex offender even when there has been no criminal verdict or successful lawsuit. The rules spell out how the untried process would work. It would largely treat a person placed on the civil registry the same way a convicted sex offender is treated under Ohio's so-called Megan's Law."
