Our lecturers are back on campus sooner than the rest of the staff. Away from their screens and in live contact with students: many lecturers are relieved, but some are concerned. Have sufficient steps been taken at our teaching locations? What about ventilation? We spoke to Michel Leenders who, as…

Genetically modified organisms (GMOs) could be useful allies in the fight against critical environmental problems. Could because the use of GMOs is strictly regulated at the moment. A Leiden student team is now trying to make these GMOs safer with the aid of an ingenious lock.

Cookware handles, electrical plugs, brake pads. Unlike other plastics, these ‘thermosets’ cannot simply be melted down and reshaped, making them difficult to recycle. Chemist Roxanne Kieltyka and her team are now exploring a way to make these materials recyclable, potentially transforming the way we…

3 October University has become something of a tradition: a bit of science among the Leidens Ontzet celebrations. During the new and improved edition, the WetenschapsWarenMarkt (Science Market), visitors spoke to researchers about the nitrogen problem, making organs and the city’s connections with A…

A new AI model will soon be able to predict the risk of infection in postoperative patients. This will allow healthcare providers to take preventive measures and detect complications at an earlier stage.

A single tiny molecule that can destroy flu, corona, HIV and Zika viruses? Yes, it really does exist. Biophysicist Niek van Hilten, who will receive his doctorate on 14 September, contributed to this discovery.

Designing innovative algorithms, thinking outside the box, and brainstorming over coffee with his colleagues — this is what physicist Stefano Polla enjoys most. His success shines through in his nomination for the C.J. Kok Jury Award 2024 for PhD thesis of the Year.

On 18 March the municipal elections will be held, and you can cast your vote strategically for what you consider important in your town. This raises at least three important questions: what is strategic voting, how do you know if you are a strategic voter yourself, and what do you need to do to use…

Last week’s sunny Lowlands festival was not just an occasion for partying and dancing. Visitors were also given a glimpse – as test volunteers – into scientific research. How do you conduct research on fear and silent communication at a festival?

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…

How can humans and computers learn from data? To research this, scientists often use so-called Bayesian methods. Although these methods are widely used, they also have limitations and are not always easy to interpret. In her dissertation Rianne de Heide describes some of these problems and introduces…
