Ancient genomes indicate population replacement in Early Neolithic Britain
The roles of migration, admixture and acculturation in the European transition to farming have been debated for over 100 years. Genome-wide ancient DNA studies indicate predominantly Aegean ancestry for continental Neolithic farmers, but also variable admixture with local Mesolithic hunter-gatherers. Neolithic cultures first appear in Britain circa 4000 bc, a millennium after...Brace, Selina ; Diekmann, Yoan ; Booth, Thomas J ; Faltyskova, Zuzana ; Rohland, Nadin …

Effect of organic acid vapors on the alteration of soda silicate glass
Organic acids were previously shown to be involved in the alteration of historic soda silicate glasses in humid atmospheres under museum storage conditions. The present study investigates the role of these pollutants on the visual, compositional and structural modification of soda silicate glasses. Replica glasses aged in humid or humid/acidic... -

Archäologie ohne Aufgaben? Wie die Fortschritte naturwissenschaftlicher Verfahren die moderne archäologische Forschung an Funden beeinflussen und verändern: Scientific archaeology - to what end? How progress in the analytical methods of the natural sciences has influenced and changed modern archaeological research on finds
Modern research on archaeological artefacts has profited considerably from the use of analytical techniques from the natural sciences. Recent research has allowed us to reconstruct considerably more precise "biographies" of artefacts than was the case previously, as illustrated by several examples from the author's own current research. However, as is...Sheridan, J A
