    The complex research, policy and industrial challenges of the twenty-first century require collaborative problem solving. Assessments suggest that, globally, many graduates lack necessary competencies. There is a pressing need, therefore, to improve and expand teaching of collaborative problem solving in our education systems.

    The web is increasingly inhabited by the remains of its departed users, a phenomenon that has given rise to a burgeoning digital afterlife industry. This industry requires a framework for dealing with its ethical implications. The regulatory conventions guiding archaeological exhibitions could provide the basis for such a framework.

    Many have argued that populism dominated the 2016 US presidential election. Textual analysis of electoral discourse in the United States, Greece and Venezuela suggests that the overall level of populism in the US election was in fact moderate. Bernie Sanders and Donald Trump engaged in populist discourse, but Trump lacked consistency.

    In response to recommendations to redefine statistical significance to P ≤ 0.005, we propose that researchers should transparently report and justify all choices they make when designing a study, including the alpha level.

    Early adolescence (age 10–14) is an important window of opportunity to address gender socialization as the basis for health and social justice. This Comment explains why this is the case and provides illustrative examples of existing evidence on strategies to promote gender equitable attitudes in young adolescents.

    Why isn’t there a strong relation between income and happiness? Why do people avoid or seek self-confirmatory or even false information? Why do they play the lottery and buy insurance? Taking account of belief-based utility can enable economics to make sense of these and a multitude of other puzzling phenomena.

    Identity formation is an important developmental process during adolescence, with several applied and public health implications. To prevent identity development from going astray, educational efforts, prevention programmes and policy initiatives are needed that help young people develop a healthy sense of identity.

    Predatory journals are a global and growing problem contaminating all domains of science. A coordinated response by all stakeholders (researchers, institutions, funders, regulators and patients) will be needed to stop the influence of these illegitimate journals.

    Our bloated prisons have become dangerous places with record levels of crowding, mental illness, drug abuse and self-harm. Should we be looking for a more humane and imaginative approach to designing prisons that seeks to rehabilitate rather than punitively punish?

    The recently updated US National Institutes of Health clinical trials policies will apply broadly to studies involving experimental manipulations of humans. These studies will require registration and reporting in ClinicalTrials.gov, grant application submission under a clinical trials funding opportunity announcement, and Good Clinical Practice training for investigators.

    Mental health technologies, such as apps, clinical texting, social media platforms and web-based tools, have arrived. Channelling these resources to help people with serious mental illnesses, clinicians in need of support, and people in low-and middle-income countries will have the most impact on the global burden of mental illness.

    Introduction of genetic evidence of a predisposition to violent or impulsive behaviour is on the rise in criminal trials. However, a panoply of data suggests that such evidence is ineffective at reducing judgements of culpability and punishment, and therefore its use in the legal process is likely to diminish.

    Moral outrage is an ancient emotion that is now widespread on digital media and online social networks. How might these new technologies change the expression of moral outrage and its social consequences?

    Plastic pollution is caused exclusively by humans. It poses growing global threats to both the ocean and society, and requires urgent action. Using psychological principles can motivate and implement change by connecting symptoms and sources.

    Advances in technology and the advent of social media have led to the emergence of a new phenomenon — cyberbullying. Although there are some similarities, approaches to tackling traditional bullying are largely ineffective in combating cyberbullying, which has been linked to adverse mental health and, in extreme cases, suicide.

    We ask a lot of our brains and they comply, carrying out petaflops of computations per second. A substantial amount of this processing power is devoted to sound processing — a process that is therefore vulnerable, but also repairable.

    Self-driving cars offer a bright future, but only if the public can overcome the psychological challenges that stand in the way of widespread adoption. We discuss three: ethical dilemmas, overreactions to accidents, and the opacity of the cars’ decision-making algorithms — and propose steps towards addressing them.

    The development of autonomous weapon systems, by removing the human element of warfare, could make war crimes and atrocities a thing of the past. But if these systems are unable to respect the principles of humanitarian law, we might create a super-intelligent predator that is beyond our control.

    Science, by its nature, is open to uncertainty and interpretation, but politicization — fuelled by motivated reasoning and advances in the technological environment — is leading to a new level of science scepticism among citizens and scientists themselves. What can be done to address these crises?

    It has long been assumed that grammar is a system of abstract rules, that the world's languages follow universal patterns, and that we are born with a ‘language instinct’. But an alternative paradigm that focuses on how we learn and use language is emerging, overturning these assumptions and many more.

    Europe has witnessed an increase in covert cultural racism that is reflected in recent political turmoil in its nation-states. Far-right movements and populists are exploiting fear about existential and ontological threats to spur the exclusion of unwanted ‘others’, such as Muslims, Roma, and refugees.

    Basic income is a democratizing reform that is long overdue. A guarantee of basic security is necessary to allow people to stand as more independent. Other institutional adjustments are needed, but basic income will help other policies designed to support human development to be more effective.
