Tessa van Schagen and Naomi Sedney know exactly how to combine their Psychology study with top-level sport. Both students are running in the 4 x 100 metre relay at the Olympic Games. Van Schagen: 'Fellow students think it's great that I'm going to Rio.'

The work done by SUMO proteins in the cells of our body is of vital importance. Molecular cell biologist Alfred Vertegaal has been studying these proteins for nine years, first with a Veni subsidy and then with a prestigious Vidi subsidy.

There are many complex links in the chain that provides patients with new drugs: from fundamental science, to clinical tests, to production. The entire chain can be found in Leiden. Leiden University, the Leiden University Medical Center (LUMC) and the businesses at the Leiden Bio Science Park (LBSP)…

The collaboration between Leiden University (Medical Center) and the Autonomous University of Barcelona forms one of the most powerful international alliances for the creation and transmission of knowledge in the field of transfusion medicine.

What is students’ engagement in problem-based learning (PBL) and case-based learning (CBL) in teacher certification programs?

A team of researchers at Leiden University’s Europa Institute authored an extensive study on the potential for a Climate and Energy Union within the EU constitutional framework. The study was published by the European Parliament in December 2024.

Nanoparticles that transport medicines to a specific part of the human body are usually broken down in the liver prematurely. Jeroen Bussmann from Leiden University has discovered a new method to prevent this from happening. Publication in ACS Nano.

Researchers from Leiden and Delft have found a way to look inside early-modern bookbindings. An x-ray technique has allowed them to search for remains of medieval manuscripts hidden inside the bindings. After the Middle Ages many manuscripts were recycled, their pages pasted inside bookbindings to provide…

The cannabinoid receptor type 2 (CB2R) is associated with several inflammatory diseases with an unmet medical need (e.g. Alzheimers, multiple sclerosis, reumatoid arthritis). Development of new chemical biology strategies to study this protein is essential to aid future development of drugs for these…

Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

The adsorption of D2 and CO2 on catalyst surfaces is studied using a molecular beam in ultra-high vacuum.

The electrochemical hydrogenation reaction is an alternative approach for the transformation of unsaturated bonds without the use of flammable dihydrogen gas.
