This month, Nature Human Behaviour published their first Registered Reports.

Skylar Brannon and colleagues show that, counter to predictions, exogenous testosterone increased sensitivity to norms in moral dilemmas.

Joyce He and Stéphane Côté find that self-insight into emotional and cognitive abilities is not related to higher adjustment. Read the story behind the paper here.

Don't miss NHB's editorial on this milestone, and the terrific blogpost from editor Marike Schiffer on what she's learned handling registered reports at the journal.

Nature Sustainability published two papers on shifts to sustainable diets.

Yuki Asano and Gesa Biermann find an increase in vegan and vegetarian recipes in an analysis of over 240,000 online recipes, and in users switching to and keeping these diets.

Sibel Eker and coauthors link a behavioural diet shift model to an integrated assessment model to identify the main drivers of global diet change and its implications for the food system.

Two papers examined the link between memory and perception.

Chunye Teng and Dwight Kravitz demonstrate bidirectional interference between visual working memory and low-level perception. (Nature Human Behaviour)

Maryam Hasantash and colleagues show that memory has a paradoxical impact on color appearance that is selective for faces when retinal mechanisms of color vision are impaired. (Nature Communications)

Other research published this month:

Jessica Jewell and coauthors estimate the climate impact of early retirement of coal power plants by members of the Powering Past Coal Alliance, and the prospects for expanding the alliance. Read the story behind the paper here. (Nature Climate Change)

Francisco Alpízar and colleagues test the impacts of a capacity-building workshop in a randomized adaptation project in Costa Rica. Read the story behind the paper here. (Nature Climate Change)

Paul Brockway and coauthors find that fossil fuels might have final energy return-on-investment ratios similar to renewables. (Nature Energy)

Abhishek Kar and collaborators use sales data to assess cooking gas adoption and the impact of India’s Ujjwala programme in rural Karnataka. Read the story behind the paper here. (Nature Energy)

Ching Jin and coauthors find that early growth patterns in substitutive systems follow power laws rather than exponentials. Read the story behind the paper here. (Nature Human Behaviour)

Pontus Strimling and colleagues propose and validate a model that explains the connection between ideology and moral opinions. (Nature Human Behaviour)

Nim Tottenham and colleagues demonstrate young children switched to a preference for an aversive conditioned stimulus if acquisition occurred in the presence of their parent (Nature Human Behaviour)

Matthew Lebowitz and coauthors find that people think prosocial behaviour is more influenced by genetics than antisocial behaviour. (Nature Human Behaviour)

Peter Schwardmann and Joël van der Weele show that people self-deceive into higher confidence if they have the opportunity to persuade others for profit, and that higher confidence aides persuasion. Read the story behind the paper here. (Nature Human Behaviour)

An Zeng and coauthors analyze scientific publication data to understand how often scientists switch topics, how topic switching has changed over time, and how it relates to research productivity. (Nature Communications)

Duje Tadin and colleagues demonstrate that spatial suppression of background motion signals is critical for rapid segmentation of moving objects. (Nature Communications)

Christopher Hoover and collaborators model effects of prawn aquaculture on poverty alleviation and schistosomiasis control in sub-Saharan Africa. (Nature Sustainability)

Rodrigo Cámara-Leret and Zoe Dennehy analyze indigenous and local knowledge on plant uses in New Guinea. (Nature Sustainability)

Eva-Marie Meemken and colleagues conduct a survey among workers in the cocoa sector in Cote d’Ivoire and their employers to determine the impact of Fairtrade on worker wages and working conditions in the small farm sector. (Nature Sustainability)

William Jaeger and coauthors use the Willamette River Valley in Oregon as a case study for how to use coupled human–natural systems to mitigate drought. (Nature Sustainability)

Haikun Wang and collaborators show that the challenges faced by individual types of Chinese cities in realizing low-carbon development differ significantly depending on economic structure, urban form and geographical location. (Nature Sustainability)
