High-quality education, research involving multiple faculties, collaboration between universities and central government funding to make all this possible: these were the topics covered in a working visit of the Standing Committee for Education, Culture and Science (OCW) to the Association of Universities…

Recent developments in AI mean nobody is anonymous nowadays. The search engine PimEyes can find any photo of anyone that’s ever been placed online. No more Tinder Swindlers… or personal privacy. Everyone’s findable now. But is that even allowed?

Tech company Eyeball collects images and data on young amateur football players on a large scale. But is this allowed? Bart Custers, Professor of Law and Data Science, and Gerrit-Jan Zwenne, Professor of Law and Digital Technologies, comment on the issue in ‘NRC’ newspaper.

Former PhD student Cameron Mackie will been awarded not one, but two dissertation prizes for his thesis on the aromatic universe. His work could provide us with a virtual sniff of space. ‘These molecules in space likely smell like a big charcoal grill!’

Electrons in graphene behave like light particles; they have no mass and can penetrate everything: very useful if you dream about nano-electronics. But you do have to channel them. Carlo Beenakker will be researching how. He has been awarded an ERC Advanced Grant of 1.5 million euro to carry out this…

Leiden University celebrated its 444th anniversary with a historical procession on 8 February. It celebrated this year’s Dies Natalis in time-honoured fashion with a ceremony in the Pieterskerk, but broke with tradition by sending professors out to primary schools.

The Dutch Research Council (NWO) has awarded Vidi grants to Leiden researchers.

Three major research projects involving Leiden scientists have been awarded a grant from NWO’s Gravitation Programme. The projects are on innovation processes, organs-on-chips and quantum software.

More than twenty years ago, Hurricane Katrina devastated the southern United States with nearly 1,400 deaths. Due to climate change, the lessons from this disaster are more relevant than ever, but the Trump administration seems to be ignoring them by cutting funding for disaster management. Anthropologist…

In 1925, two young physicists from Leiden University, George Uhlenbeck and Samuel Goudsmit, proposed a radical idea: spin. Their bold hypothesis quickly came to play a key role in physics and formed the basis for later breakthroughs in quantum mechanics. We are celebrating the anniversary of this discovery…

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this population will result in an enormous increase in the demand for food, consumables, water…

The Academy of Creative and Performing Arts (ACPA) of Leiden University and Art Institute West Den Haag are pleased to announce their close collaboration in the second season of the public series In the Making. This series, dedicated to the practice of research in the arts, will consist of seven public…

By detecting the tiny forces between a micrometer sized magnet and the spins of hydrogen nuclei, we can do MRI with a volume resolution that is approximately 12 orders of magnitude better than a conventional MRI.  

Are you in a position of talent coach, coordinator, mentor, dean, or teacher and looking for university programmes that provide an extra challenge for the students of your school? The Leiden University Honours Academy provides such a programme, where vwo-students from the final three years of high school…

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars (exoplanets). They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems. This way they address…

'Technology, law and justice' is one of Leiden Law School's four research focus areas.

The long term goal of the Biophysical Organic Chemistry/SSNMR group, headed by Prof. Huub de Groot, is to reach an understanding of structure, dynamics and functional mechanisms of membrane proteins and self-organized biological assemblies and to translate this knowledge into new concepts for nano-devices,…
