COVID-19 is comparable to climate and extinction emergencies, say scientists from the UK and US – all share features such as lagged impacts, feedback loops, and complex dynamics.

Public health bodies should consider incentivising social media influencers to encourage adolescents to follow social distancing guidelines, say researchers. Many adolescents are choosing to ignore the guidelines set out by governments during the COVID-19 pandemic, and peer-to-peer campaigns are likely to be more successful in changing attitudes.

Children who regularly walk or cycle to school are less likely to be overweight or obese than those who travel by car or public transport, a new study suggests.

Electron ‘spin’ could hold the key to managing the world’s growing data demands without consuming huge amounts of energy. Now, researchers have shown that energy-efficient superconductors can power devices designed to achieve this. What once seemed an impossible marriage of superconductivity and spin may be about to transform high performance computing.
