A team of archaeologists from the Universitat Jaume I, the University of Barcelona, and the Catalan Institution for Research and Advanced Studies (ICREA) has developed a new methodology that allows for a much more detailed, precise and objective analysis of Late Paleolithic portable art pieces. Thanks to this study, the research team was able to review several previously published pieces from Matutano Cave (Vilafamés), a reference site in the Iberian Mediterranean, with greater accuracy and demonstrate that some of the marks previously interpreted as artistic motifs are not anthropic engravings but natural surface reliefs.

Late Paleolithic art is usually characterized by very fine engravings, barely visible to the naked eye, often affected by taphonomic alterations, surface irregularities, and unclear morphologies, which complicates their identification and interpretation. This new methodology allows for a more precise analysis of the remains using photogrammetry and microtopographic analysis techniques. The results were recently published in the Journal of Archaeological Science: Reports.

The high-precision recording protocol integrates close-range photogrammetry, digital elevation models (DEM), and surface analysis based on geographic information systems (GIS) to detect and quantify extremely fine engravings at a submillimetric scale. This enables a detailed characterization of groove morphology, variations in depth and width, and cross-sectional profiles. The application of this low-cost methodology provides a more objective record of the trajectories, shapes and volumes of the engravings, supporting researchers’ interpretation work and reducing reliance on subjective assessments.

To validate the methodology, the team carried out a recording programme. This programme served as a reference framework for interpreting archaeological marks with greater reliability. Once it was verified that the new method provided reliable data, it was applied to three pieces from Matutano Cave, one of the most extensive Late Paleolithic portable art assemblages on the Iberian Peninsula, and used as a reference for the relative dating of other rock art manifestations. As a result, updated and more precise tracings were made for two of the pieces, and it was confirmed that the third does not contain anthropic engravings, as the observed marks correspond to natural rock reliefs.

A new genetic study has revealed that the people of Deep Mani, who inhabit one of the remotest regions of mainland Greece, represent one of the most genetically distinctive populations in Europe, shaped by more than a millennium of isolation. The findings, published today (4 February) in Communications Biology, reveal that many lineages can be traced back to the Bronze Age, Iron Age and Roman period of Greece.

Drone technology is poised for remarkable progress across multiple domains, with next-generation systems set to transform disaster response, healthcare, agriculture, logistics, archaeology, environmental management, farming, and numerous other fields vital for human development. Next-generation drones are expected to have far greater endurance, including extended flight ranges, longer operational duty cycles, and enhanced resilience. These capabilities will enable sustained, long-duration missions, such as long-distance medical or commercial deliveries, as well as wide-area surveillance across densely populated urban environments and expansive forested regions.

Several years ago, construction work for a new school in Frankfurt led to a discovery of regional importance: a large Roman sanctuary. This was followed by extensive excavations carried out by Frankfurt’s Monument Office. The findings can now be subjected to comprehensive scientific analysis by an interdisciplinary research team. Funding for this work has been jointly secured by the Archaeological Museum Frankfurt, Goethe University Frankfurt, and the University of Basel.

3D scans show that smaller dinosaurs did not shy away from feeding their deceased relatives. This is the conclusion of a new study from Aarhus University, recently published in the scientific journal Evolving Earth. 

Ancient people transported a wild relative of the common potato across the southwestern U.S., likely expanding the range of the species, according to a study published January 21, 2026 in the open-access journal PLOS One by Lisbeth Louderback from the University of Utah, U.S., and colleagues. This research provides new evidence that Indigenous people may have put the species on a path to domestication, while creating a unique cultural element in the Four Corners region.

The presence of S. jamesii starch on tools, combined with earlier genetic, ecological, and ethnographic research, indicates that Indigenous people intentionally transported, cultivated, and managed the plant across the Four Corners region. These activities define an “anthropogenic range” created through extensive trade networks and long-term use, a key indicator of early domestication.
