Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old. This is surprising since, according to our current understanding of…

Can the academic year be structured in such a way to give students, lecturers and researchers a bit more breathing space? To find out, Leiden University is taking part in ‘smarter academic year’ pilots.

A special find has been made in the Alkmaar Regional Archive: a number of 17th-century book bindings contained pieces of parchment from a manuscript from the 11th century. The original manuscript may have belonged to a princess who fled England after the Norman Conquest.

Two teams of astronomers, including one from Leiden University, have discovered oxygen in the most distant known galaxy, JADES-GS-z14-0. This groundbreaking discovery shows that galaxies could form much faster in the early universe than was previously thought.

Fat is a very valuable food component, packed with calories, especially important when other resources might be scarce. Our earliest ancestors in Africa already cracked open bones to extract the fatty marrow from bone cavities. But now a new study published in Science Advances demonstrates that our…

ESA’s space telescope Gaia, which maps the Milky Way, completes its active phase of scanning the sky on 15 January. Over the past decade, Gaia has made more than three trillion observations of about two billion stars and other cosmic objects. ‘Gaia is already the discovery machine of the decade,’ Leiden…

This practical guide is aimed at PhD candidates, Research Master Students, and early-career researchers from all academic disciplines. The instructions in the guide intend to inspire young researchers and to help them practice Open Science, by sharing all aspects of research as open possible.

Another year has reached its end. And what a year it has been! On December 4th staff and students of the Faculty of Archaeology came together to celebrate and reminisce. The event's central topic was the end of Jan Kolen's term as Dean. Martina Revello Lami moderated the event.

25 years ago the Faculty of Archaeology at Leiden University was founded. In the academic year of 2022-2023 several lustrum activities will be organised to celebrate this happy occasion. The year was kicked off with a vibrant party on September 8, inviting staff, students, and alumni.

On Tuesday, the 16th of May, the Faculty of Archaeology put a festive end to the 25th year celebrations. The programme included a dedication of our largest meeting room, the sealing and burying of a time capsule, and a BBQ.

An annual plan ensures that Planning & Control is embedded in the organisation. The plan states who provides what and when. This means that the right information is available at the right time, allowing for the proper financial management of the University.

In exactly 450 days’ time, on 8 February 2025, it is the university’s 450th anniversary. We are obviously going to celebrate this with our students, staff and friends. Do you have any ideas for this celebration?

Jasper Knoester, decaan van de Faculteit Wiskunde & Natuurwetenschappen, blikt terug op 2025 in "het jaar van Jasper".

For her bachelor’s thesis, Molecular Science and Technology student Madouc Bergers synthesized her own molecule that can inhibit the breakdown of sugars. Although most students do not even manage to make one building block, Madouc made three. Partly because of this, she has been nominated for the Science…

One in two people will be diagnosed with cancer. World Cancer Day on 4 February raises awareness of the impact of this devastating disease. Leiden University is conducting various studies aimed at preventing and controlling cancer. Below are just a few examples.

Astronomers led by Leiden PhD candidate Richelle van Capelleveen have, for the first time, discovered an exoplanet that has carved a bright gap in the protoplanetary disc around its star. This rare observation provides new insights into how young planets shape their surroundings.

Ten years later, a group of veterans still struggle daily with the effects of their deployment to Afghanistan. Sanne van der Wal, a PhD candidate at the Leiden University Medical Center (LUMC), conducted research into the effects of PTSD.

On Friday 5 September, to mark our 450th anniversary we celebrated the opening of the faculty year together with the Leiden Revisited alumni event. Combining both annual events was a huge success, especially as staff brought along their family, partner or friends.

Since 1 January 2020 - with the transition to the Dutch Civil Code - the system of writing off leave has changed. When you take leave, the system automatically writes off the hours that fall due first.

Researchers at the Faculty of Science work every day at the frontiers of knowledge, tackling today’s major societal challenges. Their work is recognised through grants, prizes and other awards. We highlight some of these achievements.

November marks exactly 100 years since the discovery of Tutankhamun's tomb. To celebrate this special discovery, the Faculty of Humanities, together with various parties, is organising the 'Month of Tutankhamun': a month full of activities around Egypt's most legendary pharaoh.

How can you ensure that more experimental drugs reach the finish line? At the moment, only one in twenty cancer drugs that are tested on humans makes it to the market. This is an enormous loss for patients and society. With a grant from the National Growth Fund, Oncode-PACT aims to efficiently select…

Scrap the radical cuts to research and teaching. This was researchers and students’ message to government at the opening of the new academic year. Various speakers in Leiden’s Pieterskerk highlighted the importance of science for society.

How do you know if a drug will actually work? The Leiden-based spin-off Omivera is developing a new technology that could provide clearer answers. The young company received a seed investment from the investment fund UNIIQ to support its development.

Leiden archaeologists have been digging into the municipality of Oss’s past for 50 years now and students have gained their first experience of fieldwork there. What is the result of half a century of research and teaching? Archaeologist Richard Jansen and his students take us to the largest excavation…
