- One of the most discussed issues in European archaeology is the significance and context of monumentality and the construction of long barrows and megaliths in the Neolithic. The construction of monuments in Neolithic Europe can, due to their often significant size and complexity, be interpreted as signs of collective building efforts, but the social and political background may vary from more egalitarian to highly stratified societies. During the last 20 years of surveys and archaeological excavations in southwest Scania, Sweden, new archaeological results have been produced, revealing many hitherto unknown settlements, central places for feasting, long barrows, megaliths, free-standing façades and other types of monumental constructions. This has disclosed a much more complex picture of the Early Neolithic (4000–3300calBC) Funnel Beaker Culture societies in the region. Large-scale excavations have documented a hierarchy of monumental places in Early Neolithic southern Scandinavia, probably reflecting different uses of monuments, mirroring a social hierarchy in polities. Recently, another central place has been excavated at Flackarp, south of Lund, Sweden, containing at least nine dolmens and free-standing façades, further supporting this hypothesis.

- Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data.

Early Neolithic flint extraction in south-western Sweden : transregional practices on a local scale
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Recent studies relate the introduction of Early Neolithic flint mining practices to the migration and rapid expansion of agricultural groups from north-western continental Europe into present-day Britain and southern Scandinavia. Here, the authors critically analyse this hypothesis, using a case study from south-western Sweden to demonstrate how transregional processes played out locally with their own dynamics, c. 4000 BC. They conclude that migration and population change only partly can explain what happened during the centuries immediately before and after 4000 BC. Local variation in human-material relationships also needs to be considered.
