A new study confirms that humans used Oregon's Paisley Caves as early as 12,450 radiocarbon years ago, with projectile points of the Western Stemmed tradition. The findings suggest parallel technological development and potentially pre-date Clovis sites.
Researchers from the University of Otago have provided radiocarbon dates for unusual jar and log coffin interments in southern Cambodia's Cardamom Mountains. The findings reveal that the enigmatic burial rituals were practiced from at least 1395AD to 1650AD, coinciding with the decline and fall of the powerful Kingdom of Angkor.
Researchers have developed a long and accurate chronology of ancient Egyptian dynasties using radiocarbon analysis, narrowing down historical scenarios and imposing some revisions. The study constrains previous predictions, especially for the Old Kingdom, with more accurate comparisons to surrounding areas.
Researchers have found a way to estimate a victim's age at death using their teeth, which can help identify them among multiple possible matches. By analyzing the levels of carbon-14 in tooth enamel, scientists can calculate the birth date and year of death.
Researchers at Queen's University have developed a new calibration curve that extends radiocarbon dating back 50,000 years, providing valuable insights into human evolution and climate change. The INTCAL09 curve improves earlier parts of the calibration curve and will be used worldwide by archaeologists and earth scientists.
A study by Woods Hole Oceanographic Institution researchers found that retail biofuel samples often do not contain the advertised amount of biofuel. The actual percentage of biofuel in blends like B20 ranged from 10 to 74 percent, while only 10% met US Department of Defense standards.
A new study by an international team of researchers provides a breakthrough approach to understanding the role of climate in the Neanderthal extinction. The findings suggest that there was no single climatic event that caused the extinction, but rather indirect effects on competition with other human groups.
A new study led by the University of Leeds suggests that extreme climate events did not coincide with Neanderthal extinction, contrary to previous theories. The research provides a more detailed picture of the climate at the time of the Neanderthals' disappearance, suggesting indirect competition with other human groups.
Recent research suggests that humans likely inhabited the Americas before the Clovis People, who have been considered the first inhabitants of the New World. The revised dates for the Clovis time period indicate a shorter duration and overlap with other sites, casting doubt on the Clovis-first model.
A new Cornell University study reveals the Santorini volcanic eruption occurred about 100 years earlier than previously thought, potentially rewriting Late Bronze Age history. The findings, based on radiocarbon analysis of tree rings and seeds, place the event in the late 17th century B.C., contradicting conventional estimates.
Researchers have re-dated two Neandertals from Vindija Cave, Croatia to between 32,000 and 33,000 years ago. This new age range sheds light on the chronological overlap between Neandertals and modern humans in Europe.
Radiocarbon dating reveals that New Guinean art is significantly older than previously thought, with some pieces dating back to 600-800 years ago. This challenges the assumption that such objects are ephemeral and were only used for a few generations, suggesting a more complex and long-lasting cultural tradition.
New radiocarbon dates show that mammoths became stranded on St. Paul Island about 13,000 years ago due to rising sea levels. The island's small size limited the ability of mammoths to sustain a permanent population, contributing to their eventual extinction.
The UCI-based center will utilize mass spectrometry to measure radiocarbon in plants, soils and ocean coral, providing insights into the global carbon cycle. This technology enhances Earth system science research and strengthens UCI's interdisciplinary scientific study capabilities.
