Radiocarbon testing of mortar from the Giza pyramids consistently returns dates 200 to 500 years older than the accepted ...

Kyrenia Ship Hull during excavation. Kyrenia Ship hull on the seabed off northern Cyprus during underwater excavation in the later 1960s. Updated radiocarbon calibration techniques provide improved ...

For decades, scientists have relied on tree rings to estimate how long trees can live. But new research suggests that this widely used method may have been underestimating the lifespan of many ...

Researchers at the University of Bern have for the first time been able to pin down a prehistoric settlement of early farmers in northern Greece dating back more than 7,000 years to the year. For this ...

Marine radiocarbon archives are depleted relative to the atmosphere, which is commonly expressed as the marine radiocarbon reservoir age. Here we apply an Earth system model of intermediate complexity ...

Much of our understanding of ice sheet behavior due to warming temperatures is based on how past ice sheets responded to warming associated with the end of the last ice age, 20,000 years ago. These ...
