A new study refines radiocarbon dating of marine remains and significantly improves the precision with which the human past of the Magdalenian period in the Cantabrian region of Spain can be ...

Archaeologists have discovered two Iron Age axes, but they were found thousands of miles apart. The distant locations of the two tools gave researchers new insights into the differences in ancient ...

Scientists working across the Pacific Islands have refined the timeline of Polynesian ritual construction by dating coral samples embedded in stone platforms, producing age estimates precise enough to ...

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 ...

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 ...

(PhysOrg.com) -- An international research team has mapped out an accurate chronology of the kings of ancient Egypt using a radiocarbon analysis of short-lived plant remains from the region. An ...

A cave wall covered with Paleolithic drawings of animals, including, from left, a bison in black facing left, a deer in red facing right, and a bison in red facing right. Researchers used a suite of ...

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 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 ...

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 ...
