Edge Sharpness Does Not Vary Between Palaeolithic Flake Technologies, With the Possible Exception of Levallois Débitage

Archaeometry, Volume 68, Issue 4, Page 674-686, August 2026.
ABSTRACT Investigating why hominins adopted particular flake technologies during the Mid‐to‐Late Pleistocene is essential to understanding patterns of lithic innovation. This period witnessed the emergence of Levallois technologies (~350–250 ka) and later blades, each “replacing” earlier forms.

Automated Dynamic Flow Experimentation for Rapid Kinetic Fitting of Transition Metal Catalysis

Angewandte Chemie, Volume 138, Issue 28, 6 July 2026.
We have developed an automated dynamic flow experimentation platform to automatically fit and identify the most accurate kinetic model from a generated set of candidates. Three transition metal‐catalyzed transformations were performed using this workflow.

Oxford Journal of Archaeology, Volume 45, Issue 3, Page 250-277, August 2026.
Summary This study presents a technological analysis of 18 old patinated scrapers and spalls, mostly of Quina technology, that were recycled into new scrapers of the same type at the Late Lower Palaeolithic site of Qesem Cave, Israel (420–200 kyr). Recycling scrapers into the same Quina and demi‐Quina types offers a rare, controlled opportunity to ...
