A research team from the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS) has produced the first continent-wide map of tree-ring oxygen isotopes (δ¹⁸OTR) in Asia. Published in National Science Review, the study provides a comprehensive new perspective of how atmospheric circulation, rainfall isotopes, and topography shape the isotopic fingerprints of trees—offering new opportunities for understanding past climate changes and tracing wood origins.
Scientists have found wolf remains, thousands of years old, on a small, isolated island in the Baltic Sea – a place where the animals could only have been brought by humans. The study, published in Proceedings of the National Academy of Sciences by researchers at the Francis Crick Institute, Stockholm University, the University of Aberdeen and the University of East Anglia, suggest that grey wolves may have been managed or controlled by prehistoric societies.
A multidisciplinary team develops a method based on Artificial Intelligence that determines with great precision the provenance of prehistoric archaeological materials
The remains of an extensive Bronze Age settlement on the Kazakh Steppe that was likely once a major regional hub for large-scale bronze production more than 3,500 years ago, have been revealed by an international team of archaeologists co-led by researchers from UCL.
