Archaeological finds off the coast of Java, Indonesia provide insight into the world of Homo erectus, 140,000 years ago. Skull fragments and other fossil remains provide a unique picture of how and where these early humans lived, says Leiden archaeologist Harold Berghuis.

The night side of exoplanet WASP-43b, to the surprise of astronomers, does not appear to contain methane. It is likely that extreme winds do not allow enough time for methane to form in detectable amounts. This is the conclusion of an international team of scientists, with Leiden and Amsterdam contributions,…

It doesn't happen every day that the research project of a first-year bachelor’s student results in a scientific publication. And not only that, but as first author and on the cover of a leading physics journal. ‘We have given our lab education a thorough overhaul and it is paying off.’

In the next decades, thousands of wind turbines will be added to the North Sea. Environmental scientist Chen Li identified the most beneficial areas for their construction, focusing on material use, carbon footprint, and environmental impact. His paper was published in Environmental Science & Techno…

Imparting students with a critical attitude and cross-curricular skills. That is what Rawi Ramautar wants to strive for as the new programme director (OD) of the bachelor of Bio-Pharmaceutical Sciences. 'A programme director has to create a programme of which students say: I find it challenging and…

The perfect ship is light and sleek for speed, but also needs to be strong and stable for safe sailing. These and other conflicting requirements make it difficult, even with a supercomputer, to find the ideal design. Computer scientist Roy de Winter has developed an algorithm that helps strike the perfect…

After hard work in the lab, Chemist Tirong Guo has developed a group of materials that provide a stable and efficient foundation for artificial photosynthesis. Will this enable the large-scale production of hydrogen and other useful compounds in the most sustainable way possible? Guo will defend her…

A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

We often feel at ease in a salon chair, and the conversation soon starts to flow. That feeling will be recreated in the coming weeks in the [s]TATTOO pop-up studio. Students and staff can share their thoughts, feelings or worries – and will leave with an artwork based on their story.

Cotton is the most widely used natural fibre for clothes. But how polluting are our jeans and shirts actually? Environmental scientist Laura Scherer coordinated an international research project on the impacts of cotton. ‘The purchases of consumers in Europe can contribute to water scarcity in China…

What do bats do at night when they’re not hunting? Using tiny GPS trackers, Leiden researchers discovered that pond bats spend a substantial portion of the night resting – often outdoors. This surprising insight could change the way we protect them.

Three international research projects involving Leiden University researchers will receive funding from the Una Europa university alliance.

The discovery of a planet far too large for its sun defies models about the formation of solar systems and planets. In a paper in Science, researchers, including Yamila Miguel of Leiden Observatory, report the discovery of a planet more than 13 times heavier than Earth orbiting the ultracool dwarf star…

The pesticide thiacloprid turns out to be more harmful than previously thought. It can disrupt the lives of freshwater invertebrates and their communities, upsetting the balance and functioning of entire freshwater ecosystems. This was shown by ecologist Henrik Barmentlo and colleagues, their research…

For thousands of years, beavers had a big influence on the Dutch ecosystem and the people that lived there. This is the conclusion of research by archaeologist Nathalie Brusgaard.

How do you go about the sustainable restoration of a nineteenth-century ship without affecting its historical worth? Leiden University students from the master’s programme in Industrial Ecology spent six months working on this question. We spoke to Hidde Boom (25) and Tycho Jongenelen (25), two of the…

Ever did something for the first time and got an award for it? Sabine Wenzel did. Her research about the surface of zinc oxide won her the Surface Science Young Investigator award.

Throughout the year, master's student Berber Kommerij is busy analysing medieval and early modern books and paintings. Every summer, however, she leaves for the Norwegian fjords to conduct sea kayaking tours. 'Watersports are my great love.'

Carola Hein, Professor of History of Architecture and Urban Planning TU Delft, has been affiliated with the Institute of Cultural Anthropology and Development Sociology of Leiden University since January 2022 as Professor Water, Ports, and Historic Cities. On the surface this may seem a strange combination,…

Using the James Webb Space Telescope, an international team of researchers, including Leiden Professor of Molecular Astrophysics Ewine van Dishoeck, has discovered a palette of hydrocarbons in a planet-forming disc around a young, low-mass star. The results confirm that discs around very lightweight…

Even embryos can become embroiled in an evolutionary arms race with another species. Leiden biologists demonstrate this with larvae of the rosy bitterling that parasitize the gills of freshwater mussels. They published their research on February 19 in PNAS.

In 2025, Leiden University College (LUC) celebrates its 15th anniversary with the theme 'Global challenges, local impact'. To kick off this anniversary year, we have shared fifteen stories over the past few weeks showcasing how LUC students, researchers, and alumni contribute to societal challenges…

LiDAR, a laser-based remote sensing technology, is transforming archaeology by uncovering hidden landscapes beneath forests, vegetation, and shallow waters. Though initially designed for land management, its applications in archaeology have grown rapidly.

Thank you for celebrating Pride Month with us! 🌈 Over the past month, we have honored love, diversity, and inclusion together. We hope you had a chance to stop by a DEI team member to pick up a Pride ribbon and show your support for the LGBTQ+ community. Everyone is always welcome.

Metamaterials researcher Martin van Hecke has been elected American Physical Society (APS) fellow, an honour exclusive to only half a percent of the society's members.

The United Nations Committee on the Rights of the Child (CRC) has accused Finland of violating the rights of Finnish children by leaving them in life-threatening conditions in Syrian camps. Ann Skelton, member of the committee, calls the situation 'inhuman'.
