Nienke van der Marel has been awarded the New Horizons Prize in physics for her pioneering research on planet formation. This prize is given to young, promising researchers in physics or mathematics. The astronomer and her colleagues found the first observational evidence for 'dust traps' in disks around…

Every week, Uwe Hensch walks past the Old Observatory in Leiden. In corona times, he decided to make a LEGO design of the historic building. His design is now finished and might go into production. You can help to make it happen.

Rodrigo Ochigame’s project explores how AI redefines scientific evidence, aiming to help scientists critically navigate these transformations with the Veni grant.

Petr Steindl works on quantum dots in microcavities for his PhD research. He manipulates single-photons to create complex structures of light. Applications could include quantum communication and gates for quantum computers.

From 14 to 29 PhD candidates, seven actively involved faculties and, above all, lots of innovative interdisciplinary research, all with data science as the common denominator. The university’s Data Science Research Programme (DSO) has proven so successful that after five years on a start-up grant it…

Eduard Fosch-Villaronga from Leiden University has been awarded a Starting Grant by the European Research Council (ERC). This grant of 1.5m euros enables talented early-career scholars to start their own pioneer project, lead a research team, and implement their best ideas at the frontiers of their…

Tuberculosis stands as one of the most lethal infectious diseases worldwide. A significant challenge in combatting tuberculosis lies in the emergence of antibiotic resistance triggered by genetic alterations, commonly known as mutations. These mutations can diminish the responsiveness to antibiotics,…

All over Europe you will find ethnographic museums with large collections of indigenous objects from Latin America. These collections shaped the image of native populations in the European mind. An ERC Starting Grant allows Dr Martin Berger to look at the bigger picture, contextualizing individual collections…

For the first time, an international group of astronomers have seen the heat glow of two ice giant planets colliding. They could also observe the resultant dust cloud move in front of the parent star several years later. Led by Leiden astronomer Matthew Kenworthy, they monitored the star's brightness…

When you become very good at one thing, that sometimes comes at the expense of something else. Such trade-offs also apply to bacteria. When becoming more resistant to one antibiotic, bacteria can sometimes become more sensitive to another. Linda Aulin, PhD candidate in the pharmacology group of Coen…

Before patients can take a pill, scientists often spend years in the lab developing and testing a candidate drug. That often includes experiments with laboratory animals. As head of the rodent facility, Ilze Bot and her colleagues ensure that these experiments are conducted in an ethically responsible…

How do molecules originate and evolve in space? And how does that ultimately determine the chemical composition of planets and their atmospheres? The Dutch Astrochemistry Network (DANIII) receives 1.6 million euros from NWO to find out. A large group of Leiden astronomers and chemists is contributing:…

When it comes to literature, people mostly talk about what characters see or hear. Rarely is it about what they smell. That’s a shame, thinks university lecturer Jan van Dijkhuizen. He has been awarded an Open Competition grant from NWO to expand academic knowledge about scent in literature, and to…

Workshop

More severe droughts that will also last longer: this will primarily be a problem for irrigated croplands, as discovered by environmental scientist Qi Chen. Mixed forests with a variety of plant species will be the least vulnerable. Chen compared the effects of drought on different ecosystems across…

As of April 2022, Mark de Rooij has been appointed SAILS Professor AI and Data Theory at the Institute of Psychology. This position will enable him to contribute to the goal of the interdisciplinary programme: to build on and expand the current expertise on AI within Leiden University, working from…

Scientific Director of the Leiden Academic Centre for Drug Research (LACDR) Hubertus Irth: ‘We test substances and look for new concepts for treating disease.’

From one year to the next, face masks have started to appear in the environment. As the masks are discarded, they end up in the top soil, in sediment layers, and in refuse heaps. In a couple of generations archaeologists will study the layer that has already been labeled the Face Mask Horizon. Current…

Supercomputer ALICE has been expanded, making it even more powerful and faster. This means researchers and students can work with heavier models. From language research to brain activity scans, this expansion is good news for a variety of disciplines. So who gets to work with this prima donna?

In addition to compulsory elements, most degree programmes also have elective credits. These are credits you can earn in a variety of ways, for example by taking elective courses, studying abroad or doing a minor.

Lecture, Tuesday Talks: Science Insights

Simulations of galaxy formation provide much more information about galaxies than a telescope. Simulations have been improving significantly in recent years. Astronomer Evgenii Chaikin made such a significant contribution to this field that he graduated with honours on February 27th.

Not only dark matter, but also ordinary matter and dark energy are tracked in the largest ever cosmological computer simulation ever. In the FLAMINGO simulations, you can see virtual galaxies and clusters of galaxies emerging over the course of billions of years. This is no easy task: with more than…

Lecture

On March 28, 2023, our esteemed colleague Prof. Harry Wijshoff passed away. He died after a struggle of several months against a serious illness.

Lecture, colloquium

Microorganisms that temporarily ‘go to sleep’ play an important role in the evolution and survival of a population. Mathematician Shubhamoy Nandan conducted research on the effect of this characteristic called ‘dormancy’ in a novel mathematical model.

A CT scanner to treat eye cancer, energy-efficient software for the future and a test to identify male chick eggs. Three projects by researchers from Leiden University are to receive funding from research funder NWO’s Open Technology programme, to which the business sector also contributes.

Lecture

Search engines are getting better at answering our questions. And chatbots are increasingly likely to search the internet for relevant sources. ‘Search engines and chatbots will become more closely entwined’, says Professor Suzan Verberne.

Assistant Professor Vedran Dunjko and his team receive a €100,000 gift from Google to support them in their quantum research. The research focuses on whether quantum computers can provide new ways of understanding the mysteries of high-energy physics. Google is committed to supporting ambitious research…

The dark matter of biology: clumps of sugar molecules that, for example, form sugary webs around pathogens. We know very little about them. Wouter Remmerswaal threw all his talent into the challenge – both in the lab and as a modeller – and succeeded. He received his PhD on 12th September.

An impressive 21 research projects by Leiden researchers have been awarded Veni funding from the Dutch Research Council (NWO).

Not all sustainable business models have the impact they claim, Leiden researcher Levon Amatuni revealed. Car sharing and phone reuse, for example, have a smaller positive effect than previously thought. Amatuni advises people to ‘pay attention to actual changes in their consumption behaviour rather…

Lecture, Colloquium

In the course of 2020 the Faculty of Archaeology was bolstered by some new staff members. Due to the coronavirus situation, sadly, this went for a large part unnoticed. In a series of interviews we are catching up, giving the floor to our new colleagues. We kick off with Dr Tuna Kalayci, who joined…

David Versluis successfully simulated an infant gut virtually. This is crucial for research on improvements in formula milk. Currently, such research primarily relies on diaper contents, which is not optimal. Versluis defended his doctoral thesis on April 23.

An X-ray scanner, some small metal balls, and a newly developed algorithm. That is all you need to make a 3D model that enables you to look inside art objects without dismantling them. Thanks to the research of Francien Bossema (Centrum Wiskunde & Informatica and Leiden Institute of Advanced Computer…
