Burnout is on the increase. It is caused by group pressure, being ‘on’ all the time and asking too much of ourselves. Clinical psychologist Bart Verkuil advises lowering our expectations.

‘Praesidium Libertatis is a daily responsibility.’ These were the words of Rector Magnificus Carel Stolker on 8 February during the 443rd Dies Natalis of Leiden University. The University needs to pay continuous attention to open debate if it wants to remain a bastion of freedom.

On this page, you will find the recordings of the online This Week's Discoveries from May 12, 2020, as well as a list of speakers since October 2015.

A full overview of BPOC/SSNMR PhD theses.
