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.

The guardian of our genome, the protein MutS, scans the DNA for spelling errors and makes sure they are corrected. An essential process for our health. Researchers at Leiden University Medical Centre (LUMC) have discovered precisely how this protein works by making MutS visible with cryo-electron microscopy.…

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…

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…

Sustainable biotechnology, new insights into genome evolution and combining forces in mathematics. The NWO has awarded grants to these three innovative Leiden research projects in the ENW-M Open Competition.

Early diagnosis, new treatments, and personalised care: all of these are possible if we can better unlock the wealth of information hidden in health data. Unfortunately, this data is often poorly organised, difficult to access, and not interoperable. The new international Leiden Institute for FAIR and…

This website provides an overview of the organisational structure of Leiden University. Here you can find contact details of secretariats, staff lists by department, co-participation bodies, and regulations.

From assessment periods and deadlines to invigilators and organising digital assessments. Everything you need to think about for planning, organising and communicating assessments.

Once you have completed the design of your course, you have to deal with the practical organisation of teaching. Here you find information about the faculty support.

From a workshop for ten people to a symposium with two hundred participants: the University offers a range of spaces, catering and other options for internal events.

Below you will find all information on hosting digital exams, the support available, and how you can prepare to ensure a smooth assessment process.

BRAIN Biotech and the Leiden University will jointly develop an Aspergillus based production strain with high yield and thus contribute to a bio-based circular economy. The cooperation is based on BRAIN´s molecular tool BEC.

For the second year in a row, LACDR organized an international symposium on molecular fold topology. An afternoon program centered around the theme “circuit topology”, inspired and connected mathematicians, physicists and chemists. Scientists from USA, Europe, and Asia participated in this online ev…

Assistant Professor Karlsson Linnér, who works at the Department of Economics, is one of the recipients of a Veni grant. His research on the accuracy of preventive genetic testing is a fine example of the intersection of economic science and law.

Good research means looking beyond disciplinary boundaries, said Professor of Molecular and Cellular Biochemistry Remus Dame in his inaugural lecture on 10 May. Processes that take place on DNA shouldn’t only be researched in a test tube but also in living cells, for instance.

Within the same species of butterfly many different wing patterns can occur. How is this possible? According to researchers Ben Wielstra and Emma Berdan, of the Institute of Biology Leiden (IBL), the answer lies within supergenes. A supergene is a part of a chromosome that contains many strongly linked…

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.

Paco Barona Gomez is the newest associate professor at the Institute of Biology Leiden (IBL). The Mexican researcher is fascinated by the evolution of natural products: compounds made by microbes, but also plants and animals. ‘It’s like we investigate chemical dark matter.’

On the 8th of December 2021, Leiden Academic Centre for Drug Research (LACDR) organized “Circuit Topology 2021”, the first international symposium on circuit topology. The focus was on the mathematical notion of Circuit Topology, and its applications to physics, chemistry and biomedicine.

This initiative is supported by the Leiden University Global Seed Fund (LUGF) 2025, awarded to Santy Kouwagam (VVI) and Irene Hadiprayitno (LIAS) together with Universitas Indonesia.

For the third consecutive year, LACDR organized the international symposium on topology, Circuit Topology III, on November 29, 2023. The event aimed to bring together experts from diverse fields, including mathematics, computer science, physics, chemistry, and biomedical sciences, to discuss cutting-edge…

The Organisational Development team, led by rector Erwin Muller, has organized numerous meetings with colleagues from a variety of university departments over the last few months. Together, they’ve looked at organisational challenges, bottlenecks and opportunities. From these meetings, a strong demand…

An evolutionary 'trap' that has haunted crested and marbled newts for 25 million years: Leiden researchers have uncovered a mysterious DNA error that should not be able to arise – yet persists all the same. How is that possible? PhD candidate James France found new clues.

Three Leiden researchers have been awarded a prestigious Vici grant, the Dutch Research Council (NWO) announced on Tuesday. Two of the researchers work at Leiden University and the third at the Leiden University Medical Center (LUMC).

Sebastian Pomplun receives an ERC starting grant of 1.85 million Euros in five years. He wants to develop synthetic transcription factors that can enter cells and activate or deactivate specific genes. For example to disrupt cancer-related processes or to trigger the production of an important missing…

On 16 May 2022, Professor Michel Wouters from the Department of Biomedical Data Sciences at the Leiden University Medical Centre (LUMC), will deliver his inaugural lecture titled ‘Quality of Cancer Care: why the real world matters’. Wouters will use the opportunity to describe how quality registries…

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.

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).

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.
