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.

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.

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.

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…

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.

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.

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.

In order to stop a whole range of diseases or disorders at their source, you would have to be able to switch certain genes on or off. Sebastian Pomplun wants to develop substances that can do this very precisely. For example, he wants to disrupt cancer processes and make cells produce an important missing…

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.

Leiden University’s Executive Board has appointed Erwin Muller as Vice Rector of Organisational Development. In this role, he will help further professionalise and improve the university’s organisation as per the Strategic Plan.

‘All the groceries, but not a fig for young workers’, read a banner during the occupation of Ahold’s headquarters in 1981. ‘For a long time, young workers were not taken seriously, but they managed to put themselves on the map’, says historian Rosa Kösters.

Luris supports and advises researchers and societal partners on knowledge transfer, research impact and public-private partnerships between researchers and society. The organisational structure of Luris is changing to help us better meet the changing needs of our researchers and civil society. Read…

Tuesday 27 January - A crisp winter morning and a busy Tuesday. Board matters, research safety, leadership and faculty profiling alternate throughout the day, with a focus on collaboration both inside and outside the faculty. A full day that ends with a game of darts.

The Leiden interdisciplinary research programme Global Transformations and Governance Challenges (GTGC) and the Embassy of Ireland are jointly organising a special book launch in The Hague. On 13 November, Gerry Finnegan, author and a former director of the International Labour Organisation (ILO), will…

A mediation meeting was held today between the University Council and the Executive Board about the appointment procedure for the Vice-Rector of Organisational Development, Erwin Muller. We have managed to resolve the dispute.

Researchers from the Leiden University Medical Center (LUMC) have successfully used stem cell gene therapy to treat a baby with the severe congenital immune disorder SCID. An important milestone: it is the first time stem cell gene therapy of Dutch origin has been administered to a patient, and also…

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…

During illness, the stiffness or viscosity of cells can change. Tom Evers demonstrated this by measuring such properties of human immune cells for the first time. ‘The stiffness of certain cells could be a way to make a diagnosis,’ Evers said. He defended his thesis on March 26th.

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.

Effectively treating a severe case of pneumonia is often challenging. Identifying the pathogen behind it can be difficult. PhD candidate Ilona den Hartog tried something new: ‘We searched for answers in substances our own body produces.’ PhD defence on 17 September.

How to implement good leadership? This is the central question posed during the inspiration seminars of the LLP, in which renowned guest speakers share their insights. A seminar at the beginning of May imparts this message: “Keep listening to one another.”

Professor of International Relations Daniel Thomas is clear: anyone taking peace in Europe for granted is shutting their eyes to reality.

Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…
