Ancient DNA reveals 4000 years of grapevine diversity, viticulture and clonal propagation in France - Nature Communications Here, the authors present aDNA from 49 grape pips spanning the Bronze Age to Medieval period in France and surrounding areas. They find evidence of long-distance exchange of domestic varieties through vegetative clones and one Medieval sample that is nearly identical to modern Pinot Noir.

Der Fokus auf den Atlantischen Sklavenhandel ist historisch verständlich. Wir sollten aber nicht vergessen, dass Sklaverei bis in das Paläolithikum zurückreicht, Bestandteil unseres gesellschaftlichen Verhaltens ist. Nur wenn wir uns dieser Einsicht stellen, können wir nachhaltig gegensteuern.

The Chinese identity of St Mark’s bronze ‘Lion’ and its place in the history of medieval Venice | Antiquity There are no known written records pertaining to the origins of the enigmatic bronze ‘Lion’ that stands atop one of the two large columns of the Piazzetta in St Mark’s Square, Venice (Italy). Representing the Venetian Winged Lion, a powerful symbol of statehood, the sculpture was installed during a time of political uncertainty in medieval Mediterranean Europe, yet its features do not reflect local artistic conventions. Here, the authors argue that stylistic parallels are found in Tang Dynasty China (AD 618–907); employing lead isotope analysis, they further show that the figure was cast with copper isotopically consistent with ore from the Lower Yangzi River basin.

Analysis of the Winged Lion sculpture in the Piazza San Marco suggests it began life as a tomb guardian in Tang China, modified to resemble the iconic leonine symbol of the Republic, portraying the impressive connectivity of the medieval world 2/2

Einige Aspekte aus einer zyklenbasierten Perspektive: Das Abschneiden der #AfD in RLP und Ba-Wü war erwartbar, ist Teil der gegenwärtigen Polarisierungsphase. Ob sich der Prozess kurz-mittelfristig verstärkt, hängt vom globalen Energiemarkt ab, langfristig auch von Resilienz gegen Polarisierung.

The first ‘AI societies’ are taking shape: how human-like are they? Scientists are studying forms of ‘social’ interactions between artificial-intelligence agents. Will they find a fresh form of sociology, or merely a sophisticated mime act?

Klimaforschende wenden sich an die deutsche Politik: Drei-Grad-Grenze könnte schon um 2050 erreicht werden; Klimaanpassung beschleunigen. Klimaforschende sehen für Deutschland eine Zunahme des Risikos extremer Wetterereignisse und die Notwendigkeit, Maßnahmen in der Klimaanpassung schnell zu verstärken.

Look! Another climate diagram with the Osman et al temp curve ! Looks much like ours @leizarchaeology.bsky.social . Just, we would not use the term "human civilisation" any more, and certainly not just for the Holocene. Compare:

Four challenges for usable/applied archaeologies Here, we respond to the useful comments from Kerr and Isendahl by clarifying four core elements of our argument. We frame these as four challenges for the future of usable archaeologies and hope they prove helpful in refining how archaeology might contribute meaningfully to contemporary global issues.

A space at the table? Global challenges and contemporary archaeology as plural transdisciplinary design for the future In this debate article, the authors argue that archaeologists seeking practical relevance must start with a critical, expanded understanding of the contemporary, including how communities, stakeholders and complex policy structures operate to navigate unfolding socioecological crises.

NEW Archaeologists often claim they can contribute to modern 'global challenges' such as climate change, but rarely get a space at the policymaking table
