In a large natural disaster, such as the Haitian earthquake earlier this year, or in an unsolved homicide case, knowing the birth date of an individual can guide forensic investigators to the correct identity among a large number of possible victims. Livermore researcher Bruce Buchholz and colleagues at the Karolinska Institute are looking at victim's teeth to determine how old they are at the time of death. Using the Lawrence Livermore's Center for Accelerator Mass Spectrometry, Buchholz...

Scientists today described development of 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. "This technique stands to revolutionize...

Researchers at Queen's University have helped produce a new archaeological tool which could answer key questions in human evolution. The new calibration curve, which extends back 50,000 years is a major landmark in radiocarbon dating-- the method used by archaeologists and geoscientists to establish the age of carbon-based materials. It could help research issues including the effect of climate change on human adaption and migrations. The project was led by Queen's University Belfast through...

British scientists say they have developed a new technique called rehydroxylation for dating archaeological objects by using fire and water. Researchers at the Universities of Manchester and Edinburgh said their simple method promises to become a significant technique for dating ceramic materials, just as radiocarbon dating has become for organic materials such as bone or wood. The scientists said the new technique can be used on fired clay ceramics, such as bricks, tile and pottery. Working...

AKRON, Ohio, Dec. 12 /PRNewswire/ -- An Ohio-based company has successfully grown the first Low Radiocarb(TM) food, in this case soybeans, with significantly lower levels of harmful radioactive carbon-14 than normally found in food. Infants and children nourished with safer, low radiocarbon LifeBlocks(TM) foods will suffer tens of billions fewer genetic damage events over their lifetime. By reducing genetic damage, risks of cancer and birth defects may also be reduced. Since genetic...

Researchers can now determine when a human was born by looking into the eyes of the dead Using the radiocarbon dating method and special proteins in the lens of the eye, researchers at the University of Copenhagen and University of Aarhus can now establish, with relatively high precision, when a person was born. This provides a useful tool for forensic scientists who can use it to establish the date of birth of an unidentified body and could also have further consequences for health science...
