For a long time, even many researchers thought that guide dogs were a relatively modern invention. An accidental encounter with archival material showed university lecturer Krista Milne that guide dogs helped their blind owners as far back as the Middle Ages. Milne now has received an NWO XS grant to…

Just as some people today dislike English influences on the Dutch language, in early modern times people also criticised the Frenchification of Dutch. But to what extent did French actually leave its mark in our language? PhD student Brenda Assendelft made a surprising discovery. PhD defence 24 May.

This is the first time DNA analysis has been used to…

We do it every day but barely give it a thought: chewing our food. But the ‘simple’ process of masticating food may have played a crucial role in the evolution of our jaws, facial muscles and teeth.

Psychologist Hilmar Zech found that overweight people are actually more attracted to food pictures after eating than before. He did so using an old research method that he revamped for use on smartphones. Zech will defend his PhD on 30 April.
