Environmental challenges such as plastic pollution and biodiversity loss require extensive monitoring. Citizen science, in which members of the public participate in scientific research, has therefore become an important approach in environmental science.

Physicists, including Leiden researcher, Sanli Faes, have devised a new technique for studying processes at microscale rapidly and extremely precisely. This new method will make it easier to develop antiviral medication. And it doesn’t stop there. Publication in ACS Nano.

This book connects labour history, global history and the institutional or political history of international organisations.

Leiden physicists have managed to detect a single molecule called dibenzoterrylene in a new crystal, and found that it is a candidate component for a quantum network. Future quantum computers will need such a network to work together while maintaining their advantages. Publication in ChemPhysChem jo…

Astronomers from Leiden Observatory have developed a new method to find distant quasars and better distinguish them from other objects that look like them, using machine learning techniques. The research result has been accepted for publication in the journal Astronomy & Astrophysics. It is the last…

The Dutch Public Prosecution Service (OM) will handle more criminal cases without involvement of the courts. The aim: more community service and fewer prison sentences. Jan Crijns, Professor of Criminal and Criminal Procedural Law, commented on the proposal in ‘Trouw’ newspaper.

Some offenders are given short prison sentences. They tend to be people who are generally not faring well before they go to prison; they may have difficulty finding a job for instance. A short spell in prison can make them even more vulnerable. Attention therefore needs to be paid to continual supervision…

Mensen jarenlang opsluiten in een gevangenis werkt niet en kost de samenleving veel geld, zeggen experts. Hoogleraar Criminologie en Vergelijkende Penologie Miranda Boone stelt tegenover NEMO Kennislink dat het anders moet: ‘Het strafrecht zoals we het nu inzetten, werkt niet.’

Out of prison, into the world: who will give you another chance?

A punishment that fits the crime is the cornerstone of the rechtsstaat or constitutional state. But opinions differ greatly on what constitutes a just and effective punishment.
