Rowe hopes to use it, for instance, to analyze objects such as a small ivory figurine called the "Venus of Brassempouy," thought to be about 25,000 years old and one of the earliest known depictions of a human face.The figurine is small enough to fit into the chamber used for analysis.Funding for this project is provided by the National Science Foundation, the National Center for Preservation Technology and Training, and Texas A&M University.
Scientists have developed a new method to determine the age of ancient mummies, old artwork, and other relics without causing damage to these treasures of global cultural heritage.Reporting at the 239th National Meeting of the American Chemical Society (ACS), they said it could allow scientific analysis of hundreds of artifacts that until now were off limits because museums and private collectors did not want the objects damaged.If so, are we linked to plants in very early stages of evolution?How can a tube as flimsy as a mosquito's proboscis be stiff enough to act as a hollow boring tool?Why do I, or any other human, get sore and cracked heels?
I understand it's less common in men than women – presumably this is down to footwear choices?An earlier questioner asked how metal blades in wet shavers lost their sharpness so easily on human hair.One answer said that alternating blades in a razor made each one last longer than if left in place until they became blunt."This technique stands to revolutionize radiocarbon dating," said Marvin Rowe, Ph. "It expands the possibility for analyzing extensive museum collections that have previously been off limits because of their rarity or intrinsic value and the destructive nature of the current method of radiocarbon dating.In theory, it could even be used to date the Shroud of Turin." Rowe explained that the new method is a form of radiocarbon dating, the archaeologist's standard tool to estimate the age of an object by measuring its content of naturally-occurring radioactive carbon.The cream product I use to cure it works very well, but its active ingredient appears to be urea.
