Unraveling the origins of agriculture in different regions around the globe has been a challenge for archeologists. Now researchers writing in the Proceedings of the National Academy of Sciences report finding evidence of early human experiments with grain cultivation in East Asia. They gathered this information from an unlikely source"•dog and pig bones. The dog and pig bones, as well as bones of other animals analyzed in the study, come from an archaeological site in a region of...

With help from newly developed equipment designed and built at Michigan State University, MSU researchers have been able to make first-of-its-kind measurements of several rare nuclei, one of which has been termed a "holy grail" of experimental nuclear physics. The discoveries, made at MSU's National Superconducting Cyclotron Laboratory using an isotope purification device, will help to refine theoretical models about how elements are created in the cosmos. Until now, this was beyond the...

University of Michigan researchers have developed a new tool that uses natural "fingerprints" in coal to track down sources of mercury polluting the environment. The research is published in today's online issue of the journal Environmental Science & Technology. Mercury is a naturally occurring element, but some 2000 tons of it enter the environment each year from human-generated sources such as incinerators, chlorine-producing plants and coal-burning power plants. Mercury is deposited...

Researchers at University of Utah reported Monday that a single strand of  hair can reveal a history of which areas within the United States a person has been living or spending time.The scientists compared variations in isotopes of hydrogen and oxygen found in strands of hair to those of tap water in various areas of the country. They found the isotopes corresponded, and were able to use this information to determine a person's location during recent weeks to years.Isotopes are forms of...
