Finding structure in disordered proteins and developing drugs for undruggable diseases: it might sound like mission impossible, but pharmacologist Alireza Mashaghi and his team are right on top of it. Their project was awarded by NWO through the Open Competition Domain Science -XS, a competition that…

The quantum computer is on its way, but is society ready for it? Quantum computers have a reputation of being difficult to grasp because of their complexity. This limits society’s ability to envision future applications creating a gap between society and quantum computers. A consortium of 14 knowledge…

Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

Design of a Linguistic System for Interstellar Communication Based on Logic

With the dramatic growth of the image data on the web, there is an increasing demand of the algorithms capable of understanding the visual information automatically.

Tessa Verhoef from the Leiden Institute of Advanced Computer Science and Eduard Fosch-Villaronga from eLaw- Center for Law and Digital Technologies have written an article on how affective computing should be inclusive, diverse, and work for everyone.

This thesis introduces the concept of

The most commonly used method for the taxonomic identification of tree trunks is wood anatomy. The number of experts in this area is decreasing, and education to become an wood anatomists takes many years. With the help of technology computer scientists of the Leiden Institute of Advanced Computer Science…

Dissolution processes – next to aggregation processes - play an important role for fate prediction and environmental risk assessment of metal-based nanoparticles (MNPs). It is challenging to predict the kinetics of the dissolution process of MNPs in complex systems such as we can find in in vivo and…

Dave R. Stikkolorum, Michel R.V. Chaudron, Oswald de Bruin won the Best Paper Award of the Model Gamification Contest at the ACM/IEEE Models 2012 Conference for their paper: The Art Of Software Design, a Video Game for Learning Design Principles.

Data and information should be stored in a way that computers can understand, says Barend Mons, professor of Biosemantics at the Leiden University Medical Center and Chair of the High Level Expert Group for the European Open Science Cloud. We speak with him about FAIR data, knowlets and nanopublicat…
