Sunshine, ice cream, coffee, and plenty of good vibes. Once again, students and staff made the most of the We are Science Week. Relive some of the highlights with our photo report!

Without electronics carrying out computational tasks our daily lives would look very different. Devices such as elevators, vending machines, turnstiles, washing machines and even traffic lights use a simple form of electronic computing to switch from state to state. But, what if power supply is not…

Two consortia led by Leiden researchers have been awarded over one million euros by the Dutch Research Council and the Ministry of Health, Welfare and Sport to find solutions to antimicrobial resistance.

At the start of 2025, the Faculty of Science (FWN) will take on their new roles as programme directors. Charlene Kalle, Thijs Bosker, and Maurijn van der Zee will each be responsible for one of the faculty's bachelor programmes. Their appointments are for a term of four years.

Glorious sunshine, dozens of enthusiastic academics and huge numbers of Leiden residents ensured that this year’s special jubilee version of 3 October University was a great success.

Students from ‘StudentinzetopSchool’ help schoolchildren and gain valuable teaching experience at the same time. In an online visit on 13 April, Queen Máxima spoke to pupils, students and teaching staff. She also spoke to participants from Leiden. ‘Teaching is wonderful, but it’s complex too.’

An international team of astronomers led by Dutch scientist Martijn Oei has discovered the largest pair of jets from a black hole ever seen. The 'jumbojets' extend a combined length of 140 Milky Ways. The Leiden Observatory played a prominent role in this research. The publication will feature on the…

Talking about suicide is important, but anything but comfortable. To make this difficult subject easier for students and staff to discuss, the university is organising a campaign week in line with the national campaign ‘1K Z1E J3’ (I see you) being run by Stichting 113 Zelfmoordpreventie (113 is the…

Leiden University has awarded its prestigious University Medal to Emeritus Professor Lex van der Eb. As a pioneer in genetics and molecular biology, he received this honour for his services to science and his key role in the development of the Leiden Bio Science Park (LBSP).

Martin van Hecke and Lennard Kwakernaak (Leiden university and AMOLF) develop a mechanical metamterial that can count to ten in their research.

2,240 plant extracts from 1,299 different plant species of Dutch origin. That’s the collection of the Dutch Extract Library, which has recently been transferred to the Institute of Biology Leiden. To plant biologist and contact person for this library Pingtao Ding this is a true treasury. ‘To bring…

Biologist Nataliia Machushynets felt like she was ‘looking for a needle in a haystack’, trying to find new antibiotics to help solve the problem of resistance. During her PhD research, she did find what she was looking for, in the soil beneath our feet.

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.

Antibiotic resistance is an economic problem. Pharmaceutical companies cannot earn much from antibiotic research, so they do not invest in it. This makes it important that universities do so, says Ned Buijs.

The antibiotic EVG7, developed in Leiden, has proven capable of fighting the dangerous gut bacterium C. difficile with only a minimal dose. What’s more, the bacterium is far less likely to return, a major issue with existing antibiotics. The research was published in Nature Communications.

From the first semester of 2026, Leiden University and Universidad Diego Portales (Santiago, Chile) will launch three online virtual exchange programmes. The themes are: political analysis, tensions surrounding Indigenous peoples in Latin America, and the securitisation of borders.

Thursday 15 January starts with a long journey and ends with an equally long working day full of current issues. Jasper visits the Mathematical Institute with the scientific directors of our faculty and attends a meeting on collaboration with the Ministry of defence.

What does academic freedom mean? And how do we give shape to it in Leiden? The Academic Freedom Core Team considered these questions and presented its final report on 17 June.

A true shower of awards for students from the Faculty of Science during the annual KHMW Young Talent Awards ceremony. On Monday, 25 November, no less than nine first-year students received a prize for the best academic results in their first year. In addition, there were graduation prizes for master’s…

Hester Bijl, the Rector Magnificus of Leiden University, was handed a ‘shockingly long list’ of names of missing Iranians in her office at the Administration and Central Services department on 13 December 2022.

Connecting worlds, enhancing research and teaching, and providing innovative solutions to complex social issues: that is the idea behind interdisciplinary research. In that respect, a huge amount happened at Leiden University in 2023.

No less than six Leiden projects received a grant for quantum research from the national growth programme Quantum Delta NL and the NWO. After all, in order to boost quantum technology not only industry is needed, but also science. Research towards new sensors, faster algorithms and quantum materials,…

Nano-plastics cause malformations. Meiru Wang, researcher at the Institute of Biology Leiden, looked at the extreme effects polystyrene nano-particles could have, using chicken embryos as a model. Her results were quite alarming. Especially as nano-particles are everywhere. In the air, floating through…

Researchers from the LUMC and the Universities of Granada and Almería have found a gut bacterium that is associated with stronger muscles in people and mice. Their findings, published in the journal Gut, hint at the potential for new probiotics to support muscle strength and healthy ageing.

Symposium

How has progress been made on diversity and inclusion at Leiden University over the past decade? Attendees reflected on this at the D&I Symposium 2024: Untold Stories. And in the workshops, students and staff discussed the next steps toward a more inclusive community.
