Het asielbeleid blijft een hoofdpijndossier voor het kabinet. Een akkoord zou bereikt zijn waarin iedere partij een kleine concessie zou doen. De VVD gaat uiteindelijk toch niet akkoord met deze nieuwe asielwet die gemeentes kan dwingen om asielzoekers op te vangen. De VVD fractie heeft moeite met ‘dwang’…

Leiden biophysicist Stefano Coppola has received the prestigious AXA Research Fund postdoctoral fellowship. With this grant he can work for two years on a project to research the role of mechanical factors in the development of pancreatic cancer.

Why are morpho butterflies blue? That is what high school students Frederique Kerstens and Koen van Griensven investigated in their high school profile paper at the Leiden Institute for Research in Physics. In doing so, they won the KHMW Profielwerkstukprijs 2023. ‘We didn't expect it, but are of course…

In a global effort, quantum computers are rapidly being developed. In the meantime, researchers have to learn how to write code for these devices, which are fundamentally different from conventional computers.

Leiden physicists found a surprising interaction between electrons and a resist layer. The resist appears to charge and discharge due to incoming electrons. Publication in Physical Review Letters.

Leiden physicist Milan Allan and his group have discovered an apparent paradox within a material that has zero electrical resistance. They measured trapped charges, while charges should in theory keep flowing in the absence of resistance. The discovery could provide a missing piece of one of the big…

The standard approach to build a quantum computer with Majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing—quantum chemistry—would require these qubits to be converted again into so-called fermions. Physicists from Leiden and Delft suggest…

Physicist Christopher Berg Smiet, who recently obtained his PhD in Leiden, has been awarded an NWO Rubicon. The grant allows him to conduct postdoctoral research for two years at the Princeton Plasma Physics Laboratory (PPPL) in the United States.

Cosmologists have many possible models for the Universe, of which only one can be true. A new flowchart will eliminate some of them when two specific Universe features are accurately measured. Publication in Physical Review D on 7 November.

Ten Leiden students have received a prize from the Royal Holland Society of Sciences and Humanities (KHMW). They were nominated by their degree programme. Who are these students?

Physicists at Leiden University are developing smart chips that can be programmed with light. These chips are more energy-efficient than traditional chips because they do not require a constant power supply. For this research, they will receive funding in the coming years from the Dutch Research Council…

Our research regularly receives attention in the (Dutch) popular media. Here is an overview.

In welke mate hebben domaniale structuren de machtsvorming en nederzettingsontwikkeling in en van het gewest Holland bepaald?

What is the first thing you think of when you hear the word UN? Is it just the Security Council and the ‘blue helmets’ or is there more to it? These are some of the questions tackled by the Chair’s research group.

The "Van Marum Colloquia" are a collaborative lecture series between the LION and LIC institutes, focusing on fundamental and applied surface science.

‘Culture change takes time,’ said Vice-Rector Hester Bijl at the closing panel of the University’s Diversity Symposium on 26 January. She talked about the road to a diverse and inclusive university. The symposium provided plenty of concrete examples of small steps that can already be taken.

Would you like to organise a session during the biggest multidisciplinary event in Europe - the EuroScience Open Forum (ESOF) conference - to be held in Leiden from 13 to 16 July 2022? If so, send us your proposal! Archaeologist Corinne Hofman is one of the driving forces behind the conference and…

The LUMC, Leiden University and The Hague University of Applied Sciences want to help health professionals support behaviour change in the population. Such change would help people live healthier lives and reduce their risk of disease. The Municipality of The Hague is supporting this educational project…
