Biological agents are micro-organisms such as bacteria, parasites, moulds, viruses and their waste products. This category also includes genetically modified variants (GMOs). These agents may form a risk for your health, which is why we apply a number of legal and other guidelines to prevent people…

Drained leaves and plants stripped bare. Insects can completely destroy crops. Soon, these situations may be behind us, with the new pesticide developed by Leiden and Wageningen researchers. With their plant-based ‘insect glue’, insects are incapacitated.

BPS MSc student Guus Ruiter: This year I followed this new course called Design, Analysis, and Practical Use of Biologicals at the LUMC given by Rawi Ramautar and developed for both BPS MSc and Pharmacy students. During this course, there were many different speakers, in particular from biotech companies…

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

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.

Working in a laboratory is different from working in an office. Some of the rules that apply when working in or around a laboratory are given below.

Three of the four Heineken Young Scientists Awards for 2022 have gone to researchers from Leiden: chronobiologist Laura Kervezee, physicist Jordi Tura i Brugués and health psychologist Liesbeth van Vliet.

Swarms of drones, pedestrians or the cells in your body. Those are all examples of active matter: materials whose building blocks can move autonomously. That’s what Luca Giomi studies. Giomi has been appointed Professor of theoretical physics in the area of soft matter and biological physics at the…

Together we create a healthy and safe working environment. Should an incident, dangerous situation or needle-stick injury nevertheless occur, please report it immediately. Such incidents are far more frequent than serious accidents. By reporting them we can make sure that they do not lead to serious…

A safe and healthy work environment begins with identifying risks. A risk inventory and evaluation (RI&E) maps these risks per faculty, institute, service or department. In addition to an inventory and evaluation of risks, an RI&E also contains an action plan. This allows us to reduce risks and bott…

Daniela Kraft's group has succeeded in creating a network of microparticles that is both strong and completely flexible. This may sound simple, yet they are the first in the world to succeed in doing so. A real breakthrough in soft matter physics.

Regardless of whether you work at a desk or in a lab, all workplaces have their risks. As your employer, the University aims to create a healthy workplace and to limit possible health risks. Here you will find the main risks and measures that we take to reduce them.

Salt crystals, a nano-sized golf stick and molten glass. The LION Image Award competition of 2023 yielded a lot of beautiful images once again. But in the end, only one can be the winner.

Martin van Hecke en Anne Meeussen publiceren in het tijdschrift Nature over mechanische metamaterialen. Ze hebben een nieuwe klasse multistabiele materialen ontdekt. Dit is gebaseerd op ribbeltjes plastic.

Do you often find yourself exhausted in the lecture hall or at your workplace? Not great for your mental well-being, as Laura Pape knows. She is investigating how an online self-help program can assist in addressing sleep issues and preventing mental health problems. Join her on this elevator pitch…

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

How does an embryonic stem cell decide if it becomes a heart cell or a kidney cell? That’s the question computational biologist Maria Mircea studied for her PhD research. She looked at the inside of individual cells to analyse how they change. This is what she discovered.

PhD candidate Jiangnan Ding explores how you can design a thick slab of rubber in a way that it might act as a mechanical computer bit. This so-called mechanical metamaterial is pushed in a specific way to change its shape. ‘With a very simple material, we might be able to do simple calculations in…

If we continue with our current policies, the Faculty of Humanities will face a financial shortfall in 2024 and subsequent years. The Perspective 2028 Steering Committee, led by Manon van der Heijden, has been established to advise on potential measures that can be taken to improve the financial sit…

Abuse of power, sexually transgressive behaviour and non-funny jokes: they all came up in the stage show Mindlab, which was performed at the end of September to get staff of the Faculty of Humanities to talk about undesirable and transgressive behaviour.

On the second floor of the Sylvius Laboratory, new labs are being built for researchers of the Faculties of Social and Behavioural Sciences and Humanities. After a successful tender construction has recently started.

Leiden students often prefer complicated theory and a difficult test to experiments. Yet associate professor Paul Logman believes students learn a lot from practical teaching. He challenges his students to come up with their research questions themselves. The Leiden Institute of Physics (LION) is at…

The brain structure of young people with conduct disorder differs significantly from that of their typically developing peers. This is the conclusion of an international study that analysed more than two thousand MRI scans, recently published in The Lancet Psychiatry. Dr Moji Aghajani, one of the principal…

The new SSH labs will offer great opportunities for FSW and FGW staff engaged in experimental research. The labs will be a place of inspiration, not only because of the state-of-the-art equipment, but also as a result of the increased interaction with colleagues in other disciplines.

Fiffy the chimpanzee had rapidly developed cataracts in both eyes that made her as good as blind. Eye doctors at the Leiden University Medical Center (LUMC) have now managed to replace the lenses in both her eyes. As far as we know, Fiffy, who is thought to be between 30 and 40 years old, is the first…

The LUCL has a new Scientific Director. Professor Sjef Barbiers took over the reins from Lisa Cheng with effect from 1 January. 'This is a great opportunity to contribute to a wonderful institution.'

September 26 is the European Day of Languages. There are 24 official languages in Europe but some 200 languages in total are spoken on our continent. What good are all these different languages? And should we all learn Azerbaijani or Swedish? We asked Lisa Cheng, Professor of General Linguistics.

The fact that scientists are increasingly better able to access molecular cell and tissue data also brings with it a new challenge: how can scientists find the information they need for research among the vast amount of data available?

Protests against textbooks on trans persons in America and against a reading hour by drag queens in Rotterdam: it has been raining protests recently against people with a gender expression that does not match their birth sex. Why does this evoke such resistance? We asked Professor by special appointment…
