Shroud of Turin Debunked?

Reuters is reporting that an Italian scientist has reproduced the Shroud of Turin using only materials commonly available in medieval times.  Apparently the shroud was also carbon dated in 1988 by a handful of labs and found to originate between 1260 and 1390, though skeptics argue that efforts to restore the shroud around that time are what contaminated the results.  How the image appeared on the shroud has been a mystery, but this new article definitely offers a plausible explanation.  I find it difficult to believe that there are still people out there who believe the shroud to be authentic.
