More evidence of brain plasticity: Some blind people are able to use echolocation to perceive space and objects around them in surprising detail, even though the time differences in echoes necessary to do this are two small to be consciously perceived. An fMRI study by Lore Thaler, Stephen Arnott and Melvyn Goodale revealed that people who are especially adept at this use their calcarine cortex (a.k.a. V1 or primary visual cortex) to process spatial information from the echoes. The original paper. A shorter discussion. (Previously)
Kevin Ray Underwood found guilty of first degree murder in the April 2006 killing of 10-year-old Jamie Rose Bolin. The jury only needed 20 minutes to decide on his guilt. Previously on Metafilter, because he linked here. How could a seemingly normal, albeit "single, bored and lonely", young man become a cannabalistic child rapist and murderer? Exhibits: The blog he kept for almost four years up until the day after the murder. A collection of misc information about Underwood, including (near the bottom) the text of an online chat he had with a friend after killing Bolin. An extremely disturbing transcript of his confession to the FBI. Video footage of the trial. Deliberations will begin Monday as to whether or not he will be sentenced to death.
The Mac is a typewriter. The ElectriClerk combines a 1988 Mac SE with a 1923 Underwood typewriter to produce "a fully-functional retrofitted prop computer." (Hmmm...where have I seen this before?) [via dive into mark]
