akahige writes: An Italian scientist says he has reproduced the Shroud of Turin, a feat that he says proves definitively that the linen some Christians revere as Jesus Christ's burial cloth is a medieval fake. Carbon dating tests by laboratories in Oxford, Zurich and Tucson, Arizona in 1988 caused a sensation by dating it from between 1260 and 1390. Sceptics said it was a hoax, possibly made to attract the profitable medieval pilgrimage business. But scientists have thus far been at a loss to explain how the image was left on the cloth. Garlaschelli reproduced the full-sized shroud using materials and techniques that were available in the middle ages.
