Moving forward together with the personnel monitor: 'Make sure it’s not just a one-off conversation’
If you want to stay fit, you have to go to the gym regularly, and – hopefully - cleaning our teeth is something we do at least twice a day. So, why shouldn’t we keep on working on a safe and healthy work climate, HR Director Esther van Opstal asks in a conversation on where things stand now with the…

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…
