This month we published two papers on the implications of different kinds of intelligence for task performance.

Bruno Bocanegra from Erasmus University Rotterdam and coauthors develop a new version of the Raven Advanced Matrices test for fluid intelligence that better predicts academic achievement of university students. (Nature Human Behaviour)

Jacopo Baggio from University of Central Florida and collaborators show that groups with high social and general intelligence perform better in a resource-management task when conditions deteriorate. Read the story behind the paper here. (Nature Communications)

We also published two papers on transport emissions.

Tami Bond from University of Illinois at Urbana-Champaign and coauthors explore the emissions, and health and climate impacts of US freight truck and rail transport under various policy scenarios. (Nature Sustainability)

Lambert Schneider from Wageningen University and colleagues evaluate a global scheme requiring airline operators to offset increases in carbon dioxide emissions from international flights. (Nature Climate Change)

And on the subject of emissions...

Corinne Le Quéré from University of East Anglia and collaborators explore the potential effects of energy and climate policies on emission declines in 18 developed economies. (Nature Climate Change)

Other research published this month:

James Evans from University of Chicago and coauthors find that large teams develop and small teams disrupt science and technology. Read Lingfei Wu's story behind the paper here. (Nature)

Mary McGrath from Northwestern University and Alan Gerber from Yale University  demonstrate that collaboration increases willingness to sacrifice one's own self-interest. (Nature Human Behaviour)

Wei Ji Ma and colleagues from NYU show that people follow a suboptimal rule when they switch from exploration to exploitation decision-making strategies. (Nature Human Behaviour)

Scott Huettel and colleagues from Duke University demonstrate that amount and time exert independent influences on intertemporal choice. (Nature Human Behaviour)

Eva Pool and coauthors from California Institute of Technology show that Pavlovian conditioning involves learning of different classes of responses. (Nature Human Behaviour)

Susan Schaffnit from University of California Santa Barbara and collaborators find that in contrast to "child marriage" stereotypes, early marriage serves the strategic interests of both parents and daughters in rural Tanzania. Read the story behind the paper here. (Nature Human Behaviour)

Robert Lynch from University of Turku and coauthors analyze detailed records tracking the movements and life histories of Finnish World War II evacuees to understand how refugees integrate into host societies. Read the story behind the paper here. (Nature Human Behaviour)

Liam Beiser-McGrath and Thomas Bernauer from ETH Zurich show that public support for global climate policies is unaffected by information that other countries failed to reduce their emissions. (Nature Climate Change)

P. Gonzales from Brown and Caldwell and N.K Ajami from Stanford apply a new flexible goal-based water-trading framework that combines regulatory and market incentives to a simulation of the San Francisco Bay Area. (Nature Sustainability)

Lu Liu and colleagues from Pacific Northwest National Laboratory show that water constraints in the United States can increase the cost of electricity generation. (Nature Sustainability)

Gunther Glenk from Technical University of Munich and Stefan Reichelstein from University of Mannheim show that hydrogen obtained from wind power is already cost competitive in niche applications. Read the story behind the paper here. (Nature Energy)

E. Sinha from Stanford University and coauthors find that societal choices will have a huge impact on riverine total nitrogen loading for the continental United States (Nature Sustainability)

Joan Ballester from Barcelona Institute for Global Health and coauthors describe the effect of the Great Recession on annual and seasonal changes in human mortality trends for EU countries. Read the story behind the paper here. (Nature Communications)

Rob Bellamy from University of Manchester and collaborators show that the policy used to incentivise bioenergy with carbon capture and storage affects of public support for the technology. Read the story behind the paper here. (Nature Communications)

Rani Moran and colleagues from University College London find that that a model-based retrospective inference of a reward’s cause guides model-free credit-assignment in reinforcement learning. Read the story behind the paper here. (Nature Communications)

Jörg Gross and Carsten De Dreu from Leiden University demonstrate that cooperation networks emerge from simple reputation heuristics people use when deciding to cooperate or defect. (Nature Communications)
