Radiocarbon dating uses the decay of a radioactive isotope of carbon (14C) to measure time
and date objects containing carbon-bearing material. With a half-life of 5,700±30 years …

We trace the evolution of research on extreme solar and solar-terrestrial events from the
1859 Carrington event to the rapid development of the last twenty years. Our focus is on the …

Domestication of horses fundamentally transformed long-range mobility and warfare.
However, modern domesticated breeds do not descend from the earliest domestic horse …

The concentration of radiocarbon (14C) differs between ocean and atmosphere.
Radiocarbon determinations from samples which obtained their 14C in the marine …

Early researchers of radiocarbon levels in Southern Hemisphere tree rings identified a
variable North-South hemispheric offset, necessitating construction of a separate …

This paper presents a compilation of atmospheric radiocarbon for the period 1950–2019,
derived from atmospheric CO2 sampling and tree rings from clean-air sites. Following the …

Archaeologists and researchers in allied fields have long sought to understand human
colonization of North America. Questions remain about when and how people migrated …
