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.A professor emeritus at Texas A&M University College Station, Rowe teaches at a branch of the university in Qatar.The results match those of conventional carbon dating techniques, they say.
All the while they have to keep their skin wet to enable oxygen absorption.Scientists have developed a first-of-its-kind method for determining the age of ancient artifacts without causing damage to the objects.One of the researchers, Dr Michael Obersteiner, of the International Institute for Applied Systems Analysis near Vienna, said: “The Feli X model ...provides a unique systemic view of the whole carbon cycle, which is vital to our understanding of future climate change and energy.I knew about fish that spend a good deal of time out of the water, and had heard of mudskippers.
I had no idea that males demonstrate their fitness through acrobatic flips and leaps, though.
Traditional carbon dating involves removing and burning small samples of the object.
Although it sometimes requires taking minute samples of an object, even that damage may be unacceptable for some artifacts.
“The study shows that the combined energy and land-use system should deliver zero net anthropogenic emissions well before 2040 in order to assure the attainability of a 1.5C target by 2100.” This does not necessarily mean that humans would have to stop burning fossil fuels in little over 20 years, as the researchers included natural carbon sinks – such as forests – and the use of carbon-capture technology in their calculations.
paper, the researchers wrote: “Roughly speaking, and based on current technologies, energy sector emissions will need to peak within the next decade.
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.
