| Open AccessInvestigating the role of group-based morality in extreme behavioral expressions of prejudice
Understanding motivations underlying acts of hatred are essential for developing strategies to prevent such acts against marginalized groups. Here the authors show that group-based moral values are associated with tendency to justify extreme behavioural expressions of prejudice.

| Open AccessImpact of tiered restrictions on human activities and the epidemiology of the second wave of COVID-19 in Italy
Italy introduced a system of tiered SARS-CoV-2 control measures in November 2020. Here, the authors quantify the effect of these measures on SARS-CoV-2 transmissibility and hospitalisation, and find reductions across all tiers with the greatest impacts associated with the most restrictive level.

| Open AccessNational parochialism is ubiquitous across 42 nations around the world
National parochialism is the tendency to cooperate more with people of the same nation. In a 42-nations study, the authors show that national parochialism is a pervasive phenomenon, present to a similar degree across all the studied nations, and occurs both when decisions are private or public.

| Open AccessTen-year panel data confirm generation gap but climate beliefs increase at similar rates across ages
It has been suggested that younger people care more about climate change than older people. Here, the authors present ten year panel data from New Zealand and show that despite a generation gap in starting levels, climate change beliefs have increased at similar rates across ages over the 2009-2018 period.

Whether or not a city achieves absolute sustainability is difficult to assess with existing frameworks. Here the authors, in a review, show that a further integration of consumption-based accounting and benchmarking is necessary to aid the monitoring and assessment of Sustainable Development Goals in cities.

China has pledged to achieve carbon neutrality in 2060. Here the authors find a promising option to abate 1.0 Gt CO2-eq yr−1 of carbon emissions at a marginal cost of $69 (t CO2-eq)−1 by retrofitting 222 GW of coal power plants to co-fire with biomass and upgrading to CCS operation across 2836 counties in China.

Do we mitigate climate change in a Kyoto style global agreement or via multiple agreements among smaller groups of states? Here the authors show that the best strategy may begin with regional legally binding, aggressive agreements and, as these become common, renew pursuit of a global legally-binding treaty.

| Open AccessBreaking new ground in antimicrobial stewardship in companion animal veterinary practice
Singleton and colleagues publish in Nature Communications an intervention study to reduce antimicrobial usage in companion animal practice. They identify significant reductions in antimicrobial usage with their more active intervention group over approximately a 6-month period. The study offers an exciting way forward to explore further the trial interventions and assess alternative methods to improve antimicrobial stewardship in veterinary practice.

| Open AccessClimatic conditions are weak predictors of asylum migration
Adverse climatic conditions are commonly reported to shape asylum migration, but their effect relative to other drivers is unknown. Here the authors compare climatic, economic, and political factors as predictors of future asylum flows to the EU and find that war and repression are the most important factors.

| Open AccessAn ecological approach to structural flexibility in online communication systems
Human perceptual and cognitive abilities are limited resources and consequently cheaply available information translates into hypercompetition for rewarding outcomes. Here the authors show, with empirical analysis and an ecological model, that actors-memes ecosystems evolve towards a narrow set of emergent, natural network patterns.

| Open AccessEmergency deployment of direct air capture as a response to the climate crisis
Governments may struggle to impose costly polices on vital industries, resulting in a greater need for negative emissions. Here, the authors model a direct air capture crash deployment program, finding it can remove 2.3 GtCO2 yr–1 in 2050, 13–20 GtCO2 yr–1 in 2075, and 570–840 GtCO2 cumulative over 2025–2100.

By analyzing President Trump’s tweets and data from two media sources, the authors provide evidence suggesting that when the media reports on a topic potentially harmful to the president, he tweets about unrelated issues. Further evidence from this case study suggests that these diversionary tweets may also successfully reduce subsequent media coverage of the harmful topic.
