Researchers in Leiden have, for the first time, observed how a specialised enzyme helps bacteria stay alinve when oxygen levels are low, and how that process can be blocked. The discovery opens up new possibilities for targeted antibiotics.

When a bacterium becomes more resistant to one antibiotic, it sometimes becomes more sensitive to another. To better understand this interaction, researchers from the Leiden Institute of Biology (IBL) and the Leiden Academic Center for Drug Research (LACDR) under supervision of Daniel Rozen and Coen…

Leiden PhD candidate Jo-Anne Verschoor discovered that nearly twenty percent of the bacterial strains she studied could degrade plastic, though they needed some encouragement to do so. ‘Bacteria are just like people,’ says Verschoor. Her research was published in the journal Communications Biology,…

Last Friday the global Antibiotics Awareness Week begun: an entire week dedicated to antibiotic use. Antibiotics researchers from the LACDR therefore set out to tell primary school pupils about their research. Through role-playing, pupils were drawn into the world of antibiotics: 'Can the teacher not…

More than 1.3 million people worldwide die of tuberculosis (TB) each year, making research on its prevention and control essential. Researchers from various disciplines in Leiden are studying TB. A symposium on 24 March will highlight different activities in the hope of boosting nationwide collabora…

A bacterium hiding from the immune system and picking up bits of DNA from its environment. The result: gaining new traits, such as better protection against antibiotics. Fortunately, we have not found such a damning scenario yet. However, PhD student Renée Kapteijn did find the first clues, which…

Soil that is too wet, or too dry. Or with a lot or few nutrients. Due to climate change, the differences are becoming bigger, and plants must increasingly be able to adapt to survive. How do you make plants more stress-resistant? For this purpose, researchers from Leiden, along with other universities,…

Some bacteria, it turns out, have proteins much like ours that organise the DNA in their cells. They just do it a bit differently. This is revealed by new research from biochemists at the Leiden Institute of Chemistry and the Max Planck Institute for Biology. The discovery helps us better understand…

A patent for what may be a potent, new antibiotic. And: a clear overview of promising approaches to overcome a crucial resistance tactic employed by bacteria. In the span of one week, two researchers from Leiden are receiving their PhDs, each of them on an important step in the battle against bacteria…

Transferring poo from healthy donors to the intestines of chronically ill people has beneficial effects on these recipients’ gut bacteria, also in the longer term. This is the conclusion of research by the Leiden University Medical Center (LUMC) and the Netherlands Donor Feces Bank (NDFB).

Collaborating and learning from other fields – that is what bioinformatician Hannah Augustijn enjoys most about doing research. During her PhD at Leiden University, she developed new ways to search within bacteria for the antibiotics of the future.

Two research groups involving Leiden University have been awarded a major European grant, the ERC Synergy Grant. This for research on the development of membranes that can clean water and purify medical drugs and research on the biological clock in certain bacteria.

The Social Sciences & Humanities (SSH) Labs at Leiden University are where innovative behavioural science research takes place in the domains of psychology, digital technology, language and the development of children and adolescents. We are always looking for participants for various research studi…

Each month, we publish an article showcasing how social science research and education contribute to solving societal challenges. Researchers, lecturers, students, and societal partners work together to make knowledge accessible and to make a difference. Through open science and engaged education, we…

Explore how digital technologies reshape global societies by influencing interaction, engagement & control. Delve into digital interfaces' impact on societal inequalities.

A microscope with incredible sharpness that leaves samples unharmed – Guido Stam helped develop one. During his PhD research, he combined light and electrons to study biological samples. ‘We can now measure things that simply weren’t possible before.’

This FLO event is focusing on the overlap between all 4 programs (Psychology, Educational sciences, Political Sciences end Cultural anthropology) and aims to shed more light on what defines and unites us as Social Scientists. Where is the overlap in what we do, wo who are and what we strive for? The…

Whether a microbe is beneficial or harmful to a plant can now be predicted with high accuracy thanks to bacLIFE. This bioinformatic tool with an intuitive interface makes it much easier to unlock the secrets of bacterial genomes. A group of Leiden biologists presented it in Nature Communications.

Bacteria carry countless hidden treasures in their DNA: fragments that could hold the key to new medicines. But how do you pick out the most promising ones from millions of options? ‘Look at the switches that turn genes on and off,’ says molecular biologist Gilles van Wezel.

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.

Defending your PhD research in front of nearly 300 elementary school students: that was the challenge faced by PhD candidates Jo-Anne Verschoor and Marinka de Willigen during the VUURVLIEGEN competition organised by the Centrum JongerenCommunicatie Chemie (C3). After an exciting competition, the children…

With the start of the new academic year, the Social Resilience & Security programme proudly presents their yearbook. In the yearbook, you read about the programme’s interdisciplinary research building bridges between institutes, its educational activities such as the new Minor ‘Violence Studies’ and…

...What does seem clear, though, is that there is a great deal of room for improvement in the process of out-of-home placement. The FSW's social and behavioural scientists give their views.

The need for knowledge among practitioners and the lack of an academic knowledge base for specifically collective arrangements of social work in the Netherlands were the reason for Anouk de Koning, Femke Kaulingfreks and Maartje van der Woude to start working on a Dutch Research Agenda (NWA) application…

In a recent mega-analysis, researchers from Leiden University aimed to clarify the contradictory findings of research into social anxiety disorder. They found that to obtain reliable research results having the largest possible sample size is important. Publication in NeuroImage:Clinical.

It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden PhD candidate Samuel Schwab has found that the histones in these organisms are much more diverse than previously thought. Schwab and his colleagues describe…

How do people vote? How rational are voting choices? How much do external factor weigh in? In this article social scientis provide some background.
