if the shoe fits

You can accurately judge a person just by looking at their shoes, psychologists say. "Researchers at the University of Kansas found that people were able to correctly judge a stranger's age, gender, income, political affiliation, emotional and other important personality traits just by looking at the person's shoes." Virginia Postrel responded: "The study made a solid contribution to research on first impressions, but it was hardly earthshaking. By getting so much attention, however, it demonstrated a sociological truth: People love to talk about shoes.

Neat BBC video color recovery research

Unscrambling an army of colours, reports The Guardian on the BBC's forthcoming screening of a colour-restored episode of the WWII sitcom Dad's Army. Not seen for 40 years and lost in its original PAL video colour format, it existed only as an archive on 16mm b&w film. However, the Colour Recovery Working Group found a way to recover the colour information from "chroma dots": pattern artefacts on the b&w representing unfiltered colour signal.

News from the Field on The Archeology Channel
