Smooth platinum electrodes roughen and wear when subjected to repeated cycles of oxidation and reduction, which causes nanometer-scale mounds to grow. Leiden chemists Leon Jacobse and Marc Koper, together with physicist Marcel Rost, discovered the exact details, using a unique tunneling microscope.

Medical psychologist Willeke Kitselaar developed a model that helps identify patients with persistent somatic symptoms earlier, based on an extensive large medical database. ‘I advise GPs to ask patients to fill in a questionnaire about both physical and mental symptoms at an earlier stage.’ PhD defence…

Laura van Broekhoven always knew she wanted to study archaeology, and that’s exactly what she did. Now this Leiden alumna is director of the Pitt Rivers Museum, one of the four museums of the University of Oxford.

It takes years to develop new medicines, from the test tube to trials in humans. During the process it often happens that a drug that seems promising in the initial stage has to be dropped in a later phase. This costs time and money. Leiden University and the LUMC are working closely together to make…

There seem to be genes that influence how our brains develop over time. A large international consortium has discovered this with an extensive study. The results of the study were recently published in Nature Neuroscience.
