Shroud of turin carbon dating false
A new analysis of DNA from the Shroud of Turin reveals that people from all over the world have touched the venerated garment.
Unsettled question But the new results don't settle questions about the shroud's authenticity, said Hugh Farey, editor of the British Society of the Turin Shroud newsletter. ] As far as the plant DNA goes, "they've done a good job, and they've identified a number of species that mean, broadly speaking, nothing at all," Farey told Live Science.
The neutron burst not only would have thrown off the radiocarbon dating but also would have led to the darkened imprint on the shroud. In the current study, Barcaccia and his colleagues analyzed dust that they vacuumed from the shroud that contained traces of both plant and human DNA.
The plant DNA came from all over the world, the researchers reported Oct. European spruce trees; Mediterranean clovers, ryegrasses and plantains; North American black locust trees; and rare East Asian pear and plum trees all left their mark on the cloth.
If researchers can one day figure out how to test the isotopes in the limestone dust found on the shroud, they could say with greater certainty whether the shroud was ever in Jerusalem, he said.
Tia has interned at Science News, Wired.com, and the Milwaukee Journal Sentinel and has written for the Center for Investigative Reporting, Scientific American, and Science Now.The oldest DNA snippets (which tend to be shorter because DNA breaks down over time) are found in many places on the shroud, and come from genetic lineages typically found only in India, Barcaccia said.
