    When prices are adjusted for quality, electric vehicles stood their ground to petrol cars in the early twentieth century United States. If the electricity grid had developed twenty years earlier, they might have reached a 68–79% market share and CO2 emissions per car could have declined by 60%, a new study finds.

    The ethics of research into the genetics of sexuality is not straightforward. A new study by Zietsch et al. investigates a hypothesis for the evolutionary basis of same-sex sexual behaviour. This increases our understanding of the genetics of complex behaviour, raising questions about whether and how such knowledge should be used.

    The sustainable development goals (SDGs) emphasize the inextricable connections between improved health and wider development indices. This vision is not matched by the ways that progress towards each constituent goal is achieved, and the SDGs are not on track to being met. This commentary considers theories and frameworks capturing the inter-relationships between health and its wider determinants, before discussing examples from mental health and HIV which demonstrate the power of interdisciplinary research. This commentary proposes solutions to integrate wider determinants of health into future research and practice, considering evidence from the PLuS International Interdisciplinary Researchers (PIIR) program between Arizona State University, King’s College London and the University of New South Wales, and how other approaches to interdisciplinary training can enhance clinical-academic progress in the post-COVID-19 era. Despite several frameworks promoting interdisciplinary collaboration, specialists continue to be segregated by funding, training and departmental structures. Early career researchers are well-placed to lead innovative approaches to pressing research questions. International partnership models and interdisciplinary training for early career researchers can expose participants to new perspectives and integrate wider determinants of health into future research and practice. University communities must embrace the need for a radical reimagining of boundaries and connections, if academia, too, is to “build back better.”

    That the interstellar object 1I/2017 U1 (‘Oumuamua) could be an extraterrestrial artefact is an unorthodox hypothesis. From a philosophical perspective, however, the structure of the underlying argument for the hypothesis is flawed.

    Research over the past decades has demonstrated the explanatory power of emotions, feelings, motivations, moods, and other affective processes when trying to understand and predict how we think and behave. In this consensus article, we ask: has the increasingly recognized impact of affective phenomena ushered in a new era, the era of affectivism?
