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…

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…

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…

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…

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.

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.

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.

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.

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.

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…

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 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…

Developing a better treatment for patients with head and neck cancer, that is what Binanox, The 2022 iGEM Leiden team, want to achieve. They hope to raise at least 10,000 euros for this cause. Support their crowdfunding campaign today.

The United Nations has declared May 22 the International Day for Biological Diversity. A moment of global reflection on everything on Earth and its indispensability. Anthropologist Marja Spierenburg stresses the importance of the interaction between natural and social sciences in addressing sustainability…

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…

Luca Giomi has the first results of his ERC consolidator grant. He discovered that epithelial cells move collectively but in different ways, depending on the scale you look at. It is hexatic at small scales, and becomes nematic at larger scales: it is a multiscale order. This collective movement of…
