The shroud of turin new carbon dating
"Also, the sub-genus level of taxon that has been reached is not near enough to the species level that is needed to determine the area of origin for each plant." The researchers also mistakenly relied on an interpretative method that is used to analyze thousands of grains of pollen in a lake, she said.In that environment, the conditions that led to the deposition of pollen — rain and wind, for instance — are known.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. A new analysis of DNA from the Shroud of Turin reveals that people from all over the world have touched the venerated garment."Individuals from different ethnic groups and geographical locations came into contact with the Shroud [of Turin] either in Europe (France and Turin) or directly in their own lands of origin (Europe, northeast Africa, Caucasus, Anatolia, Middle East and India)," study lead author Gianni Barcaccia, a geneticist at the University of Padua in Italy and lead author of the new study describing the DNA analysis, said in an email.
"It is very bold and completely wrong to use the same interpretational approach on the presence of DNA — or just a few pollen grains, for that matter — on a shroud that has been man-handled for decades," Enevold said.
Still, Farey said he's about 40 percent convinced the shroud is authentic and about 60 percent inclined to believe it is a forgery.
"There is a pretty substantial amount of evidence on both sides," Farey said.
"So the proper thing to do is to maintain an open mind at the moment." However, using DNA analysis and more sophisticated scientific techniques could ultimately settle the question, Farey said.
For instance, geologists can now determine the origin of rock with incredible precision, by analyzing its ratio of isotopes of certain elements.
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.
