A flint tool covered with a tar-like substance has turned out to be a top scientific find. Research by a Dutch team of scientists showed the find to be a piece of birch tar that was extracted 50,000 years ago by Neanderthals using complex techniques. The tar was used as an adhesive to make it easier…

How do you ensure that a drug has an effect on the right protein – and nothing else? Chemist Anthe Janssen explored various methods for determining the selectivity of potential medicines. He also looked at the substance BIA 10-2474, after a man died in a French clinical trial in 2016. PhD defence on…

If you expect something is going to itch, the itching really does get worse. Leiden health psychologist Danielle Bartels has proved the effect of negative expectations on itching. What’s remarkable is that this nocebo effect in itching can be reversed. ‘That offers good prospects for clinical practice,’…

‘Everyone’s talking about it, everyone thinks everyone else is doing it, but the reality is disappointing,’ says biochemist Gerard van Westen in his 3 October University lecture in the Van der Werfpark. In the full marquee, he gets a laugh with this suggestion that artificial intelligence is comparable…

Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cells membranes. This allows for selectivity and also reversibility: the binding can also be undone. Researchers first caught this phenomenon using spheres or colloids, and published…
