The prehistoric logboat was found in June by four local anglers while fishing on the river at Oldbridge, County Meath. The remains of the vessel consist of a 3m length of wood which would have formed the base of the boat. It is estimated that the logboat was originally more than 4m long, shaped out of the trunk of an oak tree using stone axes. This discovery is one of 11 logboats found in the River Boyne, though this is the first boat found to date to the Neolithic period — a sample of the wood has very recently been radiocarbon dated to between 3,,BC.

In the early morning hours of February 27, , chemist Martin Kamen sat in a cold, dark police station. Police officers apprehended the disheveled scientist, too tired to protest, outside of his laboratory at the University of California, Berkeley and hauled him to the station for questioning. They accused him of committing a string of murders that took place the previous evening. After he was released, Kamen went home for a brief nap, returned to the lab, and then made one of the most important discoveries of the 20th Century: the carbon isotope. If you want to understand anything related to biology, you start with carbon. Kamen was a child prodigy.

Radiocarbon dating is set to become more accurate than ever after an international team of scientists improved the technique for assessing the age of historical objects. The team of researchers at the Universities of Sheffield, Belfast, Bristol, Glasgow, Oxford, St Andrews and Historic England, plus international colleagues, used measurements from almost 15, samples from objects dating back as far as 60, years ago, as part of a seven-year project. They used the measurements to create new international radiocarbon calibration IntCal curves, which are fundamental across the scientific spectrum for accurately dating artefacts and making predictions about the future.
British Broadcasting Corporation Home. Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon there is left in an object. In , he won the Nobel Prize for Chemistry. This is now the most widely used method of age estimation in the field of archaeology.
