...five-day extravaganza during which more than two dozen scientists from the U.S., Italy and Switzerland performed a battery of tests on the shroud and also used pieces of tape to lift material from its surface for later study. The tests included photo- and electron microscopy, X rays, spectroscopy, ultraviolet fluorescence, thermography and chemical analyses. Among the scientists' findings: that the shroud had come into direct contact with a body and that the "blood" on the cloth is probably real blood. The figure itself bears no telltale brushstrokes and seems have been rendered by no artistic method either...
...recognized expert on certain molecules found in blood, notes emphatically of the crimson stains and rivulets that ornament the shroud, "The blood is blood, and it came from a man who died a traumatic death." In fact, he says, both chemical analyses and a telltale yellow-green fluorescence under ultraviolet light indicate the presence of remains of a slightly different substance: the fluid exuded from blood clots. That substance and its invisible-to-the-naked-eye manifestation, he says, were unknown until the 20th century, so if a medieval artist did create the image, "he must have been a genius...
...insistence, the Explora blends in with its surroundings. Hotel waste is treated with a complex system of filters, ultraviolet light and two kinds of beneficial bacteria so the sewage is crystalline before it enters Lake Pehoe. The staff burns dead wood purchased outside the park, places generators in soundproof sheds to prevent noise pollution, and uses some solar power...
Harvard will install heating, air conditioning and ventilation systems, as well as sprinkler mechanisms and improved smoke detection. Study carrels will be networked and ultraviolet filters will be put on the windows...
There may be a new heartbreak of PSORIASIS. An ultraviolet-light therapy called PUVA, when used for years to treat severe psoriasis, significantly raises the risk of the deadly skin cancer melanoma...
