Nanoplastics can accumulate in developing hearts, according to a study by biologist Meiru Wang from Leiden University. Her research on chicken embryos sheds new light on how these tiny plastic particles pose a threat to our health.

Nano-plastics cause malformations. Meiru Wang, researcher at the Institute of Biology Leiden, looked at the extreme effects polystyrene nano-particles could have, using chicken embryos as a model. Her results were quite alarming. Especially as nano-particles are everywhere. In the air, floating through…

Is aggression always bad? PhD research by psychologist Simone Dobbelaar shows that it is not. In fact, children who occasionally fiercely defend themselves and stand up for their peers often feel better mentally.

Why do some smokers quit much more easily than others? Can we think ourself to insomnia? And does playing music together help to calm conflicts? Psychology students investigated these questions and presented their findings during the Psychology Science Day 2023.

In brain diseases such as Parkinson's and Alzheimer's, proteins clump together to form fibres. ‘Chaperone proteins’ unravel those fibres, but in the test tube biochemist Anne Wentink saw that this can also cause new problems. She is going to find out what happens inside cells to determine what a drug…
