Past, present and future of local crop evolution
PLANTS, PEOPLE, PLANET, EarlyView.Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

IntCal04 terrestrial radiocarbon age calibration, 0-26 cal kyr BP [PDF]
, 2004 A new calibration curve for the conversion of radiocarbon ages to calibrated (cal) ages has been constructed and internationally ratified to replace ImCal98, which extended from 0-24 cal kyr BP (Before Present, 0 cal BP = AD 1950).

Journal of the Royal Anthropological Institute, EarlyView.Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Journal of the Royal Anthropological Institute, EarlyView.Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.

Textiles and Radiocarbon Dating
, 2014 Natural textiles provide suitable material for radiocarbon dating. Short-lived organic matter is usually involved and, if 14C dating is applied to pieces that are stylistically well dated, a better understanding of 14C dating of this type of material can

Holocene variations in the Scottish marine radiocarbon reservoir effect [PDF]
, 2004 We assessed the evidence for variations in the marine radiocarbon reservoir effect (MRE) at coastal, archaeological Iron Age sites in north and west Scotland by comparing AMS measurements of paired marine and terrestrial materials (4 pairs per context ...

Geochronology of the Upper Ice Complex (Yedoma) exposed in the Batagay Megaslump, East Siberia
Arctic, Antarctic, and Alpine ResearchThe Batagay Megaslump in eastern Siberia exposes one of the oldest permafrost archives and provides insights into Beringian paleoenvironments. However, its geochronology calls for improvement given known difficulties with permafrost dating and current ...

Collagen Fingerprinting: A New Screening Technique for Radiocarbon Dating Ancient Bone.
PLoS ONE, 2016 Collagen is the dominant organic component of bone and is intimately locked within the hydroxyapatite structure of this ubiquitous biomaterial that dominates archaeological and palaeontological assemblages.
