Researchers have discovered a link between radiocarbon dating and Egyptian historical chronology, which challenges traditional associations. The study suggests that the Minoan Santorini eruption occurred before the 18th Dynasty and during the Hyksos Period.
Scientists develop non-destructive carbon dating technique to analyze hundreds of museum collections and priceless objects like the Shroud of Turin. The new method uses plasma to oxidize surface of artifact, producing carbon dioxide for C-14 analysis.
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.
Research by Dr. Beverly Goodman exposed geological evidence of four tsunami events at Caesarea, including one from the Santorini volcano eruption in 1500 BC and others caused by underwater landslides. The findings suggest that local tsunamis could have reached 5 meters high and damaged coastal communities.
New research reveals that permafrost in the Arctic contains over 1.5 trillion tons of frozen carbon, exceeding previous estimates by a factor of two. Thawing of this carbon can lead to massive releases of greenhouse gases, further exacerbating climate change.
Scientists have developed a new dating technique using fire and water to determine the age of ceramic artifacts up to 2,000 years old. The 'rehydroxylation dating' method relies on the reaction between fired clay ceramics and atmospheric moisture, which causes weight gain over time.
Researchers found abundant tiny diamond particles in sediments dating back 12,900 years, consistent with the theory of a Clovis-age disruption by a cosmic event. The nanodiamonds are concentrated in sediment layers associated with the Younger Dryas Boundary, suggesting an environmental impact on plants and animals across North America.
University of Cincinnati geology researcher Tom Lowell discusses the latest research on the Younger Dryas event, a significant climate change event that occurred around 12,900 years ago. Lowell's team has found evidence of discrepancies in dating techniques used to study the event, which could have implications for understanding global...
Researchers at the University of Copenhagen have developed a method to determine a person's birth date using eye lens proteins, which remain unchanged after childhood. This technique has potential applications in health science research and forensic analysis, such as studying cancer tissue regeneration.
Researchers have discovered thousands of years-old plant remains exposed by the Quelccaya ice cap, suggesting that the region may not have been as warm as it is today in over 500 centuries. The findings are significant, as they provide a unique perspective on ancient climate change.
The Mladec assemblage is the oldest directly dated substantial collection of modern human remains in Europe, dating back approximately 31,000 years. The fossils confirm that early modern humans emerged in Central Europe during the Aurignacian period and provide valuable insights into their ancestry.
Scientists used two water dating methods, radiocarbon and helium-4, to determine the age of water in wells in Baldwin County, Alabama. The results showed that the ages ranged from 50 to 7,500 years, suggesting that saltwater intrusion could become a bigger issue in the future with global climate change.
Geochronologist Richard Ku's analysis of Peking Man fossils reveals they date back to at least 400,000 years ago, significantly older than previous estimates. This finding sheds new light on human evolution and challenges current understanding of the species' origins.
