anomalous trichromatism

a form of color blindness or color weakness in which affected individuals have three types of retinal cone but one of these has a color sensitivity that is different from that of the corresponding normal cones. It is usually marked by a diminished capacity to respond to the red–green color system. The ability to distinguish these colors increases in proportion to their intensity; that is, less brilliant shades are less easily identified. Also called anomalopia; anomalous trichromasy.

Megan’s law

an amendment to the Jacob Wetterling Crimes Against Children and Sexually Violent Offender Registration Act requiring that state registries of convicted but released sex offenders be disseminated to the public so that communities will be notified of offenders’ presence in a particular neighborhood. More formally known as the Community Notification Act, it was initially passed in New Jersey in 1994 after a repeat sex offender murdered a 7-year-old girl named Megan Nicole Kanka; it became a federal law in 1996.
