Two Leiden Science researchers received an NWO-XS grant for their research. Both projects are highly promising, but also high-risk. Macrophages that trap bacteria and data storage made from 2D materials convinced the board of their potential.

A Dutch-led team of astronomers has discovered that high-mass stars are formed differently from their smaller siblings. Whereas small stars are often surrounded by an orderly disk of dust and matter, the supply of matter to large stars is a chaotic mess. The researchers used the Atacama Large Millimeter/submillimeter…

Turkish and Syrian students met Rector Magnificus Hester Bijl to discuss how the university can support students who have been affected by the earthquake.

We catched up with Annette Righolt, Honours College coordinator at FGGA, about a grant, a new course and the new year.

What to do when more than forty boxes, filled to the brink with archival materials from the study of religion ranging all the way from the 1960’s up until contemporary times, ‘surfaces’? This may not be a typical question that you ask yourself on an average weekday. However, it is a question that must…

The European Research Commission (ERC) has awarded Advanced Grants to two Leiden researchers. Joke Meijer will be researching the effect of the biological clock on our health and Carlo Beenakker will be looking for Majorana fermions in superconductors.

Which molecules go into forming planets? PhD candidate Christian Eistrup and his colleagues have created new models to research this question. Their findings could change our idea of which molecules were forming Jupiter or even Earth.

The recently promoted Hao Wang from the Leiden Institute of Advanced Computer Science teaches computer programmes how to solve real-world problems. His goal is to make the process of problem-solving more efficient. On 1 November, he obtained his doctorate with the predicate cum laude. ‘I hope to solve…

Graphene has held a great promise for applications since it was first isolated in 2004. But we still don’t use it in our large-scale technology, because we have no way of producing graphene on an industrial scale. Leiden physicists have now visualized for the first time how atoms behave in between graphene…

All supermassive black holes in the centres of galaxies appear to have periods when they swallow matter from their close surroundings. But that is about as far as the similarities go. That's the conclusion reached by British and Dutch astronomers from their research with ultra-sensitive radio telescopes…

The ROBUST consortium, which is the initiative of the Innovation Center for Artificial intelligence (ICAI), has received 25 million euros from the Dutch Research Council (NWO) to strengthen fundamental AI research. The Leiden interdisciplinary research programme SAILS is part of ROBUST.

Researchers at FOM-institute AMOLF and the Leiden Institute of Physics (LION) have developed a rubber rod with strange bending behaviours. Beyond a certain point, it bends more under decreasing pressure. This behaviour doesn’t fit our expectations and does not conform to secular laws that predict the…

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…

Mass, time, space, and complexity — physicists in Leiden are launching eight new research projects tackling some of the most fundamental themes in quantum mechanics. Their goal: to push the limits of current quantum theories.

The ROBUST consortium, which is the initiative of the Innovation Center for Artificial intelligence (ICAI), has received 25 million euros from the Dutch Research Council (NWO) to strengthen fundamental AI research.

Physicist Jelmer Renema will spend two years conducting research at Oxford University in Great Britain funded by a Rubicon grant from NWO.

A team of scientists, including Leiden Astronomer Alice Booth, has discovered silicon monosulfide molecules in the dust disk around a young star. Such molecules indicate planet formation. The team made the discovery using the ALMA telescopes. This method provides an alternative when direct observation…

It takes years to develop new medicines, from the test tube to trials in humans. During the process it often happens that a drug that seems promising in the initial stage has to be dropped in a later phase. This costs time and money. Leiden University and the LUMC are working closely together to make…

Leiden astronomer Anthony Brown had the honour to give the prestigious Spitzer Lectures at Princeton University. In five lectures spread over the beginning of May, he gave an insight into the Gaia Mission. ‘One of the intellectual highlights of the year.’

Leaf-eating caterpillars greatly enrich their intestinal flora by eating soil. Even effects of plants that previously grew in that soil can be found back in bacteria and fungi in caterpillars. Researchers from the Netherlands Institute of Ecology (NIOO-KNAW) and Leiden University write about this discovery…

To eat or get eaten. It describes the evolutionary race of snakes versus the mammals and birds that prey on these snakes. Muzaffar Ali Khan devoted his PhD to investigating the molecular mechanisms play of the evolutionary arms race, and has his promotion 16 February. What makes mammals and birds successful…

An international team of astronomers has witnessed a cosmic weather event that has never been seen before.

Smart drug carriers, uneven cosmic expansion, and solar energy storage in molecules. These are the topics of three newly awarded NWO-XS grants to researchers at the Faculty of Science.

It's pretty hard to spot a single 5 nanometer particle. Leiden physicists pulled it off by turning a 120 nm gold rod into a detector.

Marcellus Ubbink has been awarded 3 million euro by NWO and Leiden University to purchase a very powerful instrument. The goal: to acquire greater insight…

The current COVID-19 vaccination campaign involves injecting the vaccine into muscle tissue, but injecting a smaller amount of vaccine in the skin might also provide good protection. The #wakeuptocorona crowdfunding campaign has enabled Anna Roukens (LUMC) to examine the safety and efficacy of vaccination…

Tic tac toe, but with quantum effects. That makes learning the principles of quantum technology a piece of cake. This is the aim of a new start-up founded by researcher Evert van Nieuwenburg: QuantumPlayed. ‘Quantum is all around us and everyone should be able to learn about it.’

The government wanted to show some muscle by making it compulsory to wear face masks in public indoor spaces as of 22.00 hours on 14 October. But it looks as though this will be 1 November after all. No need for that, tweeted Leiden professor of constitutional law Wim Voermans on 14 October, you can…

Minuscule elementary particles from space colliding with Earth can give us an insight into the distant objects they come from. But first, you need to know how to catch them. With a Vidi grant from NWO, researcher Sjoert van Velzen will 'hunt' for neutrinos coming from exploding black holes.

Putting our interns to work’ is the third-year slogan for the Master’s Programme in Medicine at Leiden University. After their regular residency periods, students are encouraged to find an internship in demanding sectors where they would like to work after completing their studies. In the MasterMindsChallenge,…
