Nanoplastics can accumulate in developing hearts, according to a study by biologist Meiru Wang from Leiden University. Her research on chicken embryos sheds new light on how these tiny plastic particles pose a threat to our health.

Twenty-two of the 150 newly elected members of the Dutch House of Representatives studied at Leiden University or did their PhD research here. But who are they and which degrees are most popular?

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

Leiden biologists have found a mutation in flour beetles that allows them to speed up their development. The study has been published in Nature Ecology and Evolution.

Face masks and plastic gloves are supposed to protect us from corona, but they are becoming an increasing problem for the environment. In a special series of the New York Times, Leiden biologist Liselotte Rambonnet and alumnus Auke-Florian Hiemstra talk about their research and the special website they…

After years of lobbying by environmental activists, a deposit scheme for small plastic bottles is to be introduced on 1 July 2021. One of the leaders in the fight is alumnus Merijn Tinga. The university will have collection points for plastic bottles and is also supporting the Plastic Spotter citizen…

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.

How do the residents of the Kooi neighbourhood in Leiden find living there? What can we do about loneliness? In this extraordinary academic year, students have been conducting all sorts of research, in Leiden. They presented their initial findings and recommendations at a Learning with the City meeting…

She narrowly defied bureaucracy and spent days angling for cod. In the North Sea, marine biologist Inge van der Knaap discovered that noise significantly disturbs fish behaviour. ‘There is now a lot of attention for underwater noise.’

What started as an idea during a social gathering led to an unexpected breakthrough in research on resistant bacteria. Biologists and chemists from Leiden developed a new substance that proves to be effective against bacteria resistant to antibiotics. They published their discovery in Nature Chemist…

Leiden academics Remco Breuker and Auke-Florian Hiemstra stand to win the title of Person of the Year.

Sustainability researchers can play an important role in the energy transition. But what if their partners are not (yet) sustainable and science itself has adverse effects? This is the subject of an online talk by researcher Thomas Franssen on 16 December with a discussion afterwards. ‘Clean energy…

Biophysicist Alireza Mashaghi and his collaborators are taking up the fight against muscular dystrophy: genetic disorders that cause muscle weakness. They want to inhibit the clumping of proteins that results in toxic aggregates. For this, the team receives 550,000 euros from Health Holland. The team…

The late 1960s: across Europe, students are demanding the right to more participation within their universities. In 1971 Leiden University was granted an elected University Council. It became quite powerful: the Council even had the right to dismiss the Chairman of the Board.

After the May elections a new University Council has now taken seat. The university democracy is the result of the long-lived national student protests in 1969. Students from Leiden joined the protests for greater representation, although their actions were less revolutionary than at other universities.…

Biologist Marcel Schaaf is one of four science faculty members who achieved the Senior Teaching Qualification in Leiden last year. How was that and what drives him? ‘Students receive way too often feedback that they cannot put into practice.’

What will happen if the lights in a large part of the city are switched off? How many stars can you see without all that light pollution? This is what researchers, artists and the residents of Leiden are going to investigate during Seeing Stars Leiden on 25 September. ‘Leiden is the ideal place for…

In dermatology, there should be a high level of multidisciplinary collaboration among institutes and specialists, Professor of Translational Dermatology, Robert Rissmann, will say in his inaugural lecture on 8 July. He is building an infrastructure that will put pre-clinical and clinical skin research…

Prof. Marcel Reinders is a data science specialist at Delft University of technology. Using smart algorithms, he searches for links in complex data. For example, he studies patterns in DNA that lead to aberrant cell behaviour. This knowledge will help detect serious diseases such as Alzheimer's and…

Hundreds of thousands of Dutch people suffer from pain caused by knee osteoarthritis and the number is rising fast. Prof. Jaap Harlaar specialises in clinical biomechanics. His research is helping improve osteoarthritis treatment. Harlaar has been appointed Medical Delta Professor and now holds posts…

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.

‘It was the biggest bunch of flowers I’d ever seen,’ says Emily Strange about the moment she won the Leiden Teaching Prize 2022. The judge praised the conservation biologist for her passion, engaging personality, and the way she motivates her students. On the Dutch Day of the Teacher, we get to know…

Genes predict whether you have a propensity for an illness but environmental factors often have the last word: nutrition, air pollution, lifestyle, stress. The exposome as both culprit and chance. Large-scale research is being carried out into this at Leiden. Thomas Hankemeier, Professor of Analytical…
