Radiocarbon records are critical to understanding the history of Earth's climate, magnetic field, and the Sun's activity, say researchers. Radiocarbon records are critical to understanding the history ...

Willard F. Libby, the American chemist well-known as the discoverer of the carbon 14 (radiocarbon) dating technique for which he won the Nobel Prize for Chemistry in 1960. Thirteen hominid teeth that ...

Sealing off a sample vial with a hydrogen-oxygen torch; the bright-white light of the extremely hot torch requires special safety goggles to avoid human eye damage. × A centuries-old kernel of corn’s ...

A cedar wood fragment sealed inside a closed channel of the Great Pyramid since construction has been radiocarbon dated to ...

Radiocarbon dating has been fundamental to the study of human cultural and biological development over the past 50,000 yr. Two recent developments in the methodology of radiocarbon dating show that ...

Members of the department of Prehistory and Archaeology of the University of Seville have published a study that includes 130 radiocarbon datings of the archaeological site in Valencina de la ...

Fossil fuel emissions could soon make it impossible for radiocarbon dating to distinguish new materials from artefacts that are hundreds of years old. Fossil fuel emissions could soon make it ...

Radiocarbon is continuously produced in the upper atmosphere. These roughly constant levels of radiocarbon from the atmosphere are then incorporated into all living organisms. Once the organisms die, ...

Pristine leaf fossils from Lake Suigetsu allowed radiocarbon dates to be calibrated against absolute dates from annual sediment layers. Photo courtesy Richard Staff In 2006, researchers drilled into ...

At four to five meters in length, the Greenland shark (Squaliformes, Somniosus microcephalus) is the largest fish native to the Arctic waters. Getting that big must take a while, and scientists have ...

From thermodynamics to GPS, from social systems theory to studies of consciousness, time plays an essential role in how we study, interpret, and understand the natural universe and the peoples and ...
