| Open AccessAuthentic self-expression on social media is associated with greater subjective well-being
It is often tempting for social media users to present themselves in an idealized way. Here, based on analyses of a large set of Facebook profiles together with a longitudinal experiment, the authors find evidence that more authentic self-expression may be psychologically beneficial, as it is related to greater well-being.

| Open AccessTemperature variability implies greater economic damages from climate change
The authors estimate the damages associated with global temperature variability. They find that variability in temperature leads to substantial uncertainty about damages, which imposes costs equivalent to a large fraction of annual consumption today.

| Open AccessHuman-like driving behaviour emerges from a risk-based driver model
Most driver models were designed for specific scenario. Here, the authors developed a driver behaviour model that can be applied to multiple scenarios and show that human-like driving behaviour emerges when the Driver’s Risk Field is coupled to a controller that maintains the perceived risk below a threshold level.

| Open AccessAnomalous supply shortages from dynamic pricing in on-demand mobility
Dynamic pricing schemes are increasingly employed in on-demand mobility. Here the authors show that ride-hailing services across the globe exhibit anomalous price surges induced by collective action of drivers, uncovered from price time-series at 137 locations, and explain under which conditions they emerge.

| Open AccessTransferring structural knowledge across cognitive maps in humans and models
Humans are able to exploit patterns or schemas when performing new tasks, but the mechanism for this ability is still unknown. Using graph-learning tasks, we show that humans are able to transfer abstract structural knowledge and suggest a computational mechanism by which such transfer can occur.

| Open AccessClimate action requires new accounting guidance and governance frameworks to manage carbon in shelf seas
Accounting guidelines exist for carbon flows in terrestrial and coastal ecosystems, but not shelf sea sediments. In this Review, the authors explore whether effective management of carbon stocks accumulating in shelf seas could contribute to a nation’s greenhouse gas emissions reduction targets.

| Open AccessPrior knowledge promotes hippocampal separation but cortical assimilation in the left inferior frontal gyrus
Prior knowledge strongly impacts new learning, but its influence on the neural representation of novel information is unknown. Here, the authors show multiple neural codes for learning: prior knowledge leads to integrated cortical representations, while promoting hippocampal separation.

| Open AccessNatural emotion vocabularies as windows on distress and well-being
Having a rich negative emotion vocabulary is assumed to help cope with adversity. Here, the authors show that emotion vocabularies simply mirror life experiences, with richer negative emotion vocabularies reflecting lower mental health, and richer positive emotion vocabularies reflecting higher mental health.

The quality of human language translation has been thought to be unattainable by computer translation systems. Here the authors present CUBBITT, a deep learning system that outperforms professional human translators in retaining text meaning in English-to-Czech news translation, and validate the system on English-French and English-Polish language pairs.

| Open AccessAttentional priorities drive effects of time pressure on altruistic choice
Forcing people to choose quickly often changes pro-social behavior, but it is unclear why. Here, the authors show that under time pressure, people engage in incomplete information searches biased by concern (or lack thereof) for others, explaining effects often attributed to automatic processing.

| Open AccessDirect and indirect punishment of norm violations in daily life
People regularly punish norm violations using gossip and direct confrontation. Here, the authors show that the use of gossip versus direct confrontation is context sensitive, with confrontation used more when punishers have more to gain, and gossip used more when the costs of retaliation loom large.

| Open AccessThe impact of agency on time and risk preferences
Scholars have long argued for the central role of agency—the size of one’s opportunity set—in the human experience, but there has been little work on how a sense of agency affects behavior. We demonstrate that increasing agency leads to greater patience and risk tolerance, even if these new opportunities are not exercised.

| Open AccessParticipatory practices at work change attitudes and behavior toward societal authority and justice
Local participatory experiences can influence broader democratic attitudes and participation. Here, in two field experiments in US and China, the authors find that participatory work meetings led workers to be less authoritarian and more critical about societal authority and justice, and more willing to participate in political and social decision-making.

| Open AccessUsing publicly available satellite imagery and deep learning to understand economic well-being in Africa
It is generally difficult to scale derived estimates and understand the accuracy across locations for passively-collected data sources, such as mobile phones and satellite imagery. Here the authors show that their trained deep learning models are able to explain 70% of the variation in ground-measured village wealth in held-out countries, outperforming previous benchmarks from high-resolution imagery with errors comparable to that of existing ground data.

There lacks a European cost-benefit analysis of possible protective measures against rising seas. Here the authors used a probabilistic data and modeling framework to estimate costs and benefits of coastal protection measures and found that at least 83% of flood damages could be avoided by dyke improvements along a third of the European coastline.

Natural hazards can have huge impacts on individuals and societies, however, monitoring the economic recovery in the aftermath of extreme events remains a challenge. Here, the authors find that Facebook posting activity of small businesses can be used to monitor post-disaster economic recovery, and can allow local governments to better target distribution of resources.

| Open AccessSaving less in China facilitates global CO2 mitigation
The partial effects of saving rate changes on CO2 emissions remain unclear. Here the authors found that the increase in saving rates of China has led to increments of global industrial CO2 emissions by 189 million tonnes (Mt) during 2007-2012, while global CO2 emissions would be reduced by 186 Mt if the saving rates of China decreased by 15 percentage points.
