Proteases degrade matrix molecules in the atherosclerotic plaque, thereby reducing atherosclerotic plaque stability. Mast cells, that contain proteases such as tryptase and chymase, have been identified at the site of rupture in specimens of human coronary arteries and their number in the plaque was…

A mega-dam around Europe is a possible solution as protection against rising sea levels. Whether that is really a good idea, was debated on by young professionals during the debate on the future of European coastal protection. 'A big dam may seem safe, but actually isn't,' argued debate winner Haye…

Thijs Bosker and Paul Behrens, Professors in Environmental Sciences at Leiden University College in The Hague, have received funding from the Leiden University Fund and the Gratama Foundation to work on developing a set of Local Actions: tangible and practical exercises that students can engage in…

They cooperate in offering wide-ranging master programs in Statistical Science and Data Science, and provide many opportunities…

On Thursday 10 November, the GTGC organized a research seminar. During this seminar Saori Katada presented her paper on Regional Approach to Financial Statecraft: Japan and India in the Face of Rising China.

In his PhD research in the field of public administration, Mark Reijnders looked at why people do not receive the help they need. They lose their way in the labyrinthine support system or become bogged down in bureaucracy. In public administration this is known as non-take-up of social care. PhD defence…

How do protein modifications work together to repair DNA, and what can we learn about these interactions to better understand disease?

Enzymes are innately sensitive to changes in the amino acid sequence, which largely constrains their evolutionary potential, i.e., evolvability. This evolutionary burden can be alleviated in the presence of stabilizing mutations, which increase the buffering capacity of enzymes to tolerate mutations…
