A series of radiocarbon measurements from Japan's Lake Suigetsu will give scientists a more accurate benchmark for dating materials, especially for older objects. Researchers extracted cores containing organic material from the bottom of the Japanese lake where it had lain undisturbed for tens of thousands of years. They provide a more precise way to examine radiocarbon ages of organic material for the entire 11,000-53,000-year time range.
