Always wanted to go to a real art auction? Now’s your chance! On 15 February over a hundred works from the LUMC’s art collection will go under the hammer. ‘It’s great fun just to be there, regardless of whether you buy anything,’ says dean and auctioneer Pancras Hogendoorn.

Just like scientific articles, patents cite scientific literature to support their findings. These references provide valuable information on how science is used to develop practical applications. However, extracting this information from patents is not that simple.

In a new Leiden-Delft-Erasmus Universities white paper, researchers and practitioners start the conversation that society desperately needs to have. ‘We’ve outsourced the visionary thinking to tech companies.’

At Leiden University over 400 enthusiastic and dedicated emergency response officers make sure our students and staff are safe, says emergency response training…

The Schoof cabinet has presented its budget. As expected, higher education is facing severe cuts. In the coming period, the Executive Board will regularly look at the consequences of what it deems an irresponsible policy.

With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery…

We, the Executive Board and deans, have recently heard from different sources that the conflict between Israel and Hamas continues to evoke strong feelings of tension, anxiety and insecurity within our university community. We take this very seriously and so are once again addressing you all.

For the first time, we’re seeing what Euclid sees. The telescope’s initial observations have provided a wealth of new information about our universe. But according to cosmologist Alessandra Silvestri, this is just the beginning. The research helps us gain a deeper understanding of the past, present,…

Tjerk Oosterkamp's group is conducting what is perhaps the coldest research in the world. The researchers have cooled a sensor to below 2 millikelvin - almost as cold as absolute zero. This allows them to make extremely sensitive measurements. PhD candidate Jaimy Plugge helped build the setup: ‘We are…

By looking at stars in dwarf galaxies research Bas Zoutendijk is trying to gain new insight into dark matter.

They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

How do galaxies form? That is what astronomer Mariska Kriek will be researching in the coming years. She received an NWO Vici grant of 1.5 million euros to study galaxies in the early universe. ‘This research uses new and unprecedented observations from the James Webb Space Telescope (JWST). These allow…

We want to be an engaged community where we feel heard and enjoy working together. But how do we have an open conversation about difficult topics?

Innovations only achieve true success when people actually use them. PhD researcher Max van Haastrecht developed a cybersecurity app for small businesses and learned how essential it is to align technology with real-world practice.

More CO2 in the atmosphere is making food crops more calorific, less nutritious and potentially more toxic.

Francesca Albanese, UN Special Rapporteur for human rights in the occupied Palestinian territories, visited Leiden Law School on 8 December within the scope of International Human Rights Day.

Tapping to a rhythm, recognizing sound patterns and enjoying music: For people, it is common sense. But is this also the case for animals? It is the research topic of Michelle Spierings, a researcher at the Institute of Biology Leiden, and it is nominated for the Klokhuis Wetenschapsprijs.

During the Summer School Science Communication, you will learn everything about science communication.

Researchers have used AI to reconstruct the rules of a board game carved into a stone found in the Dutch city of Heerlen. The team concludes that this type of game was played several centuries earlier than previously assumed.

Nadia Bouras will give the Annie Romein-Verschoor Lecture on 6 March. She will call for academic freedom for everyone.

Leiden University Medical Center (LUMC), as a partner in the reNEW consortium, is once again receiving tens of millions of euros for research into new treatments based on stem cells. The collaboration will receive a total of €150 million to develop new therapies in regenerative medicine.

Pim Overgaauw is at his best when he can support others. His new position as Institute Manager of the Mathematical Institute is therefore a perfect fit. ‘My main goal is to ensure that our mathematicians can focus on the maths.’

In his research, he uses the tools and methods of physics and applies these to today’s most important challenges in electrochemistry. Now, he brings his internationally recognized expertise in nanoscale electrochemistry to Leiden University, where he contributes to pioneering solutions for the energy…

We will mark the start of Christmas together in the Great Auditorium on 22 December, with the Sempre Crescendo student music company singing Christmas carols for our students and staff. Enjoy atmospheric organ music, sing-along carols and mulled wine afterwards. ‘It’ll be a gem of an event,’ says Beadle…

Sustainable rose smell that can be produced on a large scale. Tobias Fecker made this into a possibility during his master's thesis, which was a collaboration between the IBL and the TU Delft. He wins the fourth edition of the Krijn Rietveld Memorial Innovation Award.

X-ray and CT scanners are widely used devices in research, diagnostics and the industrial sector. And yet they are not nearly as fast and accurate as we would like. Mathé Zeegers is researching the newest technique in the field at the Centre for Mathematics and Computer Science: spectral X-ray imaging.…

Professor of International Relations Daniel Thomas is clear: anyone taking peace in Europe for granted is shutting their eyes to reality.

Providing each cancer patient with the right treatment remains a challenge. Oncode Accelerator aims to change this by innovating the way we develop cancer treatments, thus ensuring the patient is at the heart of the process.

The first full-colour images of the cosmos from ESA's space telescope Euclid were presented today. Never before has a telescope been able to take such crystal-clear astronomical images of such a large part of the sky and so far into the deep universe. The five images illustrate Euclid's full potential;…

Annetje Ottow is the first female president of the Executive Board of Leiden University, which means a return to her Alma mater.

The student debate in Leiden’s Stadsgehoorzaal promised to be ‘the key to your vote’. That may sound hyperbolic, but what this well-attended debate did achieve was increased trust in politics. ‘They even let each other finish their sentences’, the flabbergasted students concluded at the end.

Many people have fled to the Netherlands since the outbreak of war in Ukraine, including students. But even before this war, students with refugee backgrounds were eager to study at Leiden University. How does the University help young people from various backgrounds find their way around the Dutch…
