With this algorithm, new medicines can be found more quickly
Did he dare take a gamble with his PhD research? Jeroen Methorst didn’t have to think long about it. It could fail or turn out very well. The latter is the case. Methorst developed a computer system that helps researchers find the protein they need. ‘Our whole group is now using this program.’ Methorst…

Algorithms can also learn without examples
In donut-shaped buildings, particle accelerators take super-detailed X-ray images. Yet those images are not good enough to learn how to drive on hydrogen for example. Mathematics PhD student Allard Hendriksen has developed an algorithm that improves the images without having to learn from data from…

Depressed adolescents gain little benefit from eye contact with their parents (although connection is so very important)
Eye contact between parents and children improves their mood and increases feelings of connectedness on both sides; but not in the case of depressed adolescents, Mirjam Wever discovered. Where the parent-child bond has been disrupted, it can be strengthened not only with therapy for the child but also…

Can Parkinson's be stopped by unravelling protein fibres? Anne Wentink finds out with a Vidi grant from NWO
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…
