Early diagnosis, new treatments, and personalised care: all of these are possible if we can better unlock the wealth of information hidden in health data. Unfortunately, this data is often poorly organised, difficult to access, and not interoperable. The new international Leiden Institute for FAIR and…

An impressive 12 researchers from Leiden University have been awarded an 800,000-euro grant by the Dutch Research Council (NWO). This will enable them to develop their own line of research over the next five years.

Are all murderers calculating psychopaths with an obscene predilection for bloody chainsaws? Yes, if Hollywood is to be believed, but in the real world they are generally everyday people with problematic backgrounds. Professor of Violence and Interventions Marieke Liem therefore calls for the demythologisation…

How safe are the nanoparticles in transparent sunscreen, anti-odour socks and bacteria-resistant plasters? Although microbes are present on all organisms, the tools that estimate the safety of nanomaterials still hardly take them into account. Bregje Brinkmann explored the role of these microbes during…

After hard work in the lab, Chemist Tirong Guo has developed a group of materials that provide a stable and efficient foundation for artificial photosynthesis. Will this enable the large-scale production of hydrogen and other useful compounds in the most sustainable way possible? Guo will defend her…

Predicting the collective behaviour of systems, like a large group of people electing one of the parties, is no easy task. But there’s a theory that scientists have been using for decades to do just that: the theory of Gibbs measures. Last week, mathematician Mirmukhsin Makhmudov earned his PhD for…

To inhibit proteins that contribute to the growth of aggressive cancer cells, that’s the plan of Professor Bob van de Water and his team. They will receive over 700,000 euros from the KWF Dutch Cancer Society for their research. Researcher Maaike Vreeswijk and pathologist Danielle Cohen are affiliated…

In medical and psychological sciences, little research has been specifically conducted on women. Hormonal fluctuations were considered too intricate.

Running, walking or horseback riding: colleagues from the Health, Medical and Neuropsychology unit are each working up a sweat this month to raise money for research on Multiple Sclerosis. How much have they collected so far?

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process. Biophysicists from Delft University of Technology and Leiden University developed a technique that speeds up screening…

The Leiden University interdisciplinary program Liveable Planet is working on a ‘Liveable Planet Academy’ as a follow-up to its activities. The coordinating team visited the transdisciplinary Leuphana University (Germany) to get inspiration for the setup of the academy.
