An assessment of Libyan legislation

‘Dutch politics are changing, but they also are characterised by stability; that tension fascinates me.’ Sarah de Lange studies, among other things, the Dutch party system, and specifically how the rise of extremist parties influences democracy. She will start as a professor in Leiden in mid-October…

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…

Which genes are involved in woodiness and associated traits such as drought tolerance, flowering time, stem elongation, life span, and plant herbivory, and how do these gene regulatory pathways overlap?
