Why do we need fundamental science? For a lot of reasons, speakers showed at the Lustrum Symposium ‘Science Matters’. This symposium was held on 18 March 2016 to celebrate the 200th anniversary of the Faculty of Science.

The behaviour of strongly correlated electron systems, such as high-temperature superconductors, defies explanation in the language of ordinary quantum theory. A seemingly unrelated area of physics, string theory, might give physicists a better understanding of the weird behaviour of these kinds of…

Methods of treatment for chronic illnesses are limited. Doctors and researchers at Leiden University Medical Center (LUMC) and Leiden University are working on new therapies as an alternative for organ transplants. The goal is to cure the illnesses by restoring organs to their original function. Stem…

Social science research helps us understand human behaviour and social structures. These are determined by various factors, which makes the research complex and increases the likelihood of drawing the wrong conclusions. The choice of research method and analysis is therefore extremely important. It…

Bones contain information about people’s lives such as where they came from, their age at death and which diseases they suffered from. Researchers can deduce a lot from them about a person’s life and about human evolution. This generates leads that could help solve present-day problems, such as how…

The ability to create objects and structures with our hands has been essential to human development. This ability is something modern society is at risk of losing. Leiden archaeologists gather knowledge about ancient processes of ‘making and creating’ over the centuries, knowledge that helps our current…

If a society is to be secure, sustainable and resilient, conflicting interests must be reconciled. Researchers at Leiden University study the behaviour of individuals, groups and states in relation to this issue, and use their knowledge to promote equality within and between communities.

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

Health is a wonderful gift, both for humans and for society. If we are able to prevent both physical and mental illnesses, we can spare a lot of suffering and fight rising health costs. Social scientists and physicians in Leiden are working closely together to conduct research on the human mental, behavioural…
