Tuesday 7 September sees the release of the book ‘Plots stond het Leidse leven stil’ by Charlotte Boin, a freelance writer from Leiden. This book of interviews gives an impression of the turbulent effect of coronavirus on the lives of students, researchers and partners of Leiden University.

Leiden researchers Arko Ghosh and Enea Ceolini analysed the usage data of hundreds of mobile phones and discovered that our body has rhythms ranging between 7 and 52 days. These cycles influence how we behave. Their research resulted in an article in npj Digital Medicine journal, a Nature Portfolio…

Cotton is the most widely used natural fibre for clothes. But how polluting are our jeans and shirts actually? Environmental scientist Laura Scherer coordinated an international research project on the impacts of cotton. ‘The purchases of consumers in Europe can contribute to water scarcity in China…
