Our research in the area of safety sciences aims to increase the mechanistic understanding of cellular toxicity of drugs and, in a broader sense, chemicals.

Chemistry is all around us: from nutrition and smartphones to medicine. The field is developing rapidly, as the world population continues to grow and resources become scarce. MST will educate you on the basics of working towards a clean and healthy world.

Kan een computer in de rechtszaal net zo goed uitspraak doen als een rechter? Hoogleraar Recht en informatica Jaap van den Herik vindt volmondig van wel. Hij legt het uit in een college van de Universiteit van Nederland.

To strenghten ties with the public, press, other academics and wider society, LION employs an outreach officer.

The worldwide race to the quantum computer is in full swing. This computer can bring about a breakthrough in discovering medicines and new materials. Leiden researchers, together with the TU Delft, are taking part in the race. There is now a dossier online about their work.

Every year, the Leiden Institute of Physics (LION) organises the Science Day. The goal is to highlight the newest research at LION, to socialise, and to welcome first year master students and new PhD candidates to our institute.

American physicist and quantum computing pioneer Seth Lloyd is the 65th Lorentz professor. He will deliver the Ehrenfest lecture on 5 June, and several more lectures on quantum computing on 11, 18 and 25 June.

By carrying out fundamental research and providing excellent education, universities become a breeding ground for innovation and entrepreneurship.

Scientists, including our faculty colleague Dr. Mike Field, studying an exceptionally well-preserved woolly rhinoceros have revealed details of what Britain's environment was like 42,000 years ago. The beast's remains were discovered in Staffordshire in 2002, buried alongside other preserved organisms…

Historiography of science is in its current self-image a non-evaluative discipline. Its main goal is to understand past processes of knowledge formation on their own terms. In the last few decades this approach has greatly improved our understanding of the phenomenon of science. Yet, something strange…
