www.physorg.com February 11th … Gerry McCormac and Paula Reimer of Queens University in Belfast (the ’14 Chrono Centre’) have created a new archaeological tool, a calibration curve that reaches back 50,000 years ago. The curve is known as INTCAL09 and full details are published in the journal Radiocarbon. It not only extends the C14 calibration curve but also improves earlier parts of the curve – which will prove very interesting. More information is available online at http://chrono.qub.ac.uk
