Young people tend to take more risks than children or adults. This trend is related to the reward centre in the brain, which is much more active when they are rewarded, PhD candidate Barbara Braams discovered. Personality, testosterone levels and social context also play a role in risk-taking.

Neeltje Blankenstein receives an LUF grant to conduct research on online risk behaviour among young people. What risks do young people take online and why? 'With this research, we not only want to help prevent serious risk behaviour, but also understand what drives young people to it.'

To explore…

Populist parties in national parliaments have a different style of working from their colleagues in other parties. They often vote against Cabinet proposals, but do not ask more questions about Cabinet activities. This is the finding of Leiden research in different European countries.

Does the sitter have agency in the making of a photographic portrait? And if so how?

Governments are increasingly facilitating the roll-out of so-called “smart meters”, a technology for measuring energy consumption that are able to transmit and receive data using a form of electronic communication. However, implementation has been slow or even stalled.

In the public debate on the coronavirus, bold assertions from academics, doctors and other medical practitioners are often heard. For example, that the coronavirus would be no more deadly than the flu. Or that measures to combat the virus like wearing face coverings are unnecessary.

A neuro-ecological perspective on adolescent prosocial development

If you replace the standard hydrogen atoms in ice with a heavier variant, something odd happens. The volume occupied by the molecules increases by 0.1 per cent. Leiden chemist Jörg Meyer and his colleagues have created a theoretical model that describes this behaviour. Their research appeared on the…
