- When someone violates a social norm, others may think that some sanction would be appropriate. We examine how the experience of emotions like anger and disgust relate to the judged appropriateness of sanctions, in a pre-registered analysis of data from a large-scale study in 56 societies. Across the world, we find that individuals who experience anger and disgust over a norm violation are more likely to endorse confrontation, ostracism and, to a smaller extent, gossip. Moreover, we find that the experience of anger is consistently the strongest predictor of judgments of confrontation, compared to other emotions. Although the link between state-based emotions and judgments may seem universal, its strength varies across countries. Aligned with theoretical predictions, this link is stronger in societies, and among individuals, that place higher value on individual autonomy. Thus, autonomy values may increase the role that emotions play in guiding judgments of social sanctions.

- Embryo development of sediment-dwelling amphipod Monoporeia affinis is sensitive to contaminant exposure. Therefore, embryo aberrations in gravid females are used to detect the biological effects of contaminant exposure in the Baltic Sea benthic habitats. The indicator based on the aberration frequencies in wild populations (ReproIND) is currently used for environmental status assessment within the Marine Strategy Framework Directive, Descriptor 8.2. However, so far, it has mainly been applied in the Bothnian Sea (BoS) and the Western Gotland Basin (WGB), where it was found to respond to contaminant pressure and non-chemical environmental factors, such as temperature. To expand the applicability of the indicator to other Baltic Sea basins, we used field data from the gulfs of Finland and Riga, BoS, and WGB to investigate the relationships between reproductive disorders and contaminants and environmental factors, thus evaluating the indicator suitability in these areas. Despite the natural variability of the environments and contaminant distribution across and within the basins, we found that high concentrations of contaminants, e.g. metals, PAHs, and PCBs, contribute significantly to the embryo aberrations in M. affinis. These findings support ReproIND applicability in the Baltic Sea and, perhaps, in other marine areas.

- Western Eurasia witnessed several large-scale human migrations during the Holocene1–5. Here, to investigate the cross-continental effects of these migrations, we shotgun-sequenced 317 genomes—mainly from the Mesolithic and Neolithic periods—from across northern and western Eurasia. These were imputed alongside published data to obtain diploid genotypes from more than 1,600 ancient humans. Our analyses revealed a ‘great divide’ genomic boundary extending from the Black Sea to the Baltic. Mesolithic hunter-gatherers were highly genetically differentiated east and west of this zone, and the effect of the neolithization was equally disparate. Large-scale ancestry shifts occurred in the west as farming was introduced, including near-total replacement of hunter-gatherers in many areas, whereas no substantial ancestry shifts happened east of the zone during the same period. Similarly, relatedness decreased in the west from the Neolithic transition onwards, whereas, east of the Urals, relatedness remained high until around 4,000 bp, consistent with the persistence of localized groups of hunter-gatherers. The boundary dissolved when Yamnaya-related ancestry spread across western Eurasia around 5,000 bp, resulting in a second major turnover that reached most parts of Europe within a 1,000-year span. The genetic origin and fate of the Yamnaya have remained elusive, but we show that hunter-gatherers from the Middle Don region contributed ancestry to them. Yamnaya groups later admixed with individuals associated with the Globular Amphora culture before expanding into Europe. Similar turnovers occurred in western Siberia, where we report new genomic data from a ‘Neolithic steppe’ cline spanning the Siberian forest steppe to Lake Baikal. These prehistoric migrations had profound and lasting effects on the genetic diversity of Eurasian populations.
