Since then, the technique of radiocarbon dating has been improved so that it can be used with much smaller samples---fractions of milligrams instead of the original 8 grams. This has made it less intrusive when dealing with precious art and in trying to figure out the authenticity of artefacts like the Shroud of Turin.</p> Fri, 07 Apr 2023 10:00:00 +0000 Enrico Uva B.Sc. Dip. Ed. 9465 at /oss /oss/article/technology/case-saltair-sally <p>In October 2000, while walking along the shores of the "Great Salt Lake" near Salt Lake City, two hunters made a gruesome discovery. In a plastic bag, they found a white sock, a shirt, a few bones and a human skull to which long blond hair was attached. Despite their best efforts the police was unable to identify the victim. They nicknamed her "Saltair Sally" after a resort near where the remains were found.  A search through missing person records, a comparison of dental records, widespread distribution of composite pictures and the description of personal effects, were of no help.</p> Mon, 15 Apr 2013 19:02:29 +0000 Ariel Fenster PhD 1910 at /oss
