'What nature made isn’t necessarily an optimized medicine to use in the human body,’ says Professor of Biological Chemistry Nathaniel Martin. That’s why a group of Leiden researchers is making a chemistry-based improved version of the frequently used antibiotic vancomycin. They received an NWO NACTAR…

Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cells membranes. This allows for selectivity and also reversibility: the binding can also be undone. Researchers first caught this phenomenon using spheres or colloids, and published…

Destroying proteins from the Golgi apparatus of the cell in a controlled manner. That is the focus of chemist Marta Artola’s pioneering research. By developing a groundbreaking technology to target specific proteins in the Golgi, Artola aims to unlock new ways for drug development. For this ambitious…

They have been awarded three grants of 100,000 euros within the Senior Fellows programme and four grants of 50,000 euros within…

Cancer immunotherapy represents a significant breakthrough in cancer treatment. However, tumors have numerous mechanisms by which they evade destruction by the immune system. It is therefore necessary to decipher and reverse these mechanisms in order to improve immunotherapies.

Herman Spaink knows of many substances that may help combat tuberculosis. Lab space to study them safely is very limited in Leiden. A brand-new lab at Universitas Gadjah Mada in Indonesia will soon provide a solution. About time, says Spaink, ‘The disease is on the rise and is becoming less sensitive…

Leiden researchers have developed a groundbreaking model to advance cancer immunotherapy. Using a 3D printer, they create mini-tumors within an environment that closely mimics human tissue. They have also developed a method to monitor real-time interactions of these mini-tumours with immune cells during…

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process. Biophysicists from Delft University of Technology and Leiden University developed a technique that speeds up screening…

How do organs work in the body, and how can we create mini-organs to study diseases and test new medicines? That’s the idea behind organ-on-a-chip technology. During his PhD, Flavio Bonanini worked on developing the best possible mini-livers. ‘Make them as simple as possible, and as complex as neede…

As many as seven first-year students from the Faculty of Science were honoured as young talents. In addition, the Royal Holland Society of Sciences and Humanities (KHMW) also lauded three master's students and an astronomy project during a vibrant ceremony on 28 November. Professor of Science Communication…

Two Leiden Science researchers received an NWO-XS grant for their research. Both projects are highly promising, but also high-risk. Macrophages that trap bacteria and data storage made from 2D materials convinced the board of their potential.

Gerard van Westen has received the KNCV Gold Medal, the most important Dutch award for chemists under 40. 'It's a huge honour,' says the professor of AI and medicinal chemistry. 'I am now part of the group of people I was always impressed by.'

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.

On 15 April, our much-beloved and highly respected former colleague Dr Hans Brussee passed away from cancer. In January 2025, Hans began experiencing neck pain. Initially, it appeared to be a herniated disc, but sadly, the diagnosis was soon revised, and his condition proved untreatable. Hans was 77…

Understanding the behaviour of tiny droplets in our cells could aid the search for new treatments. A team of Leiden researchers has developed a groundbreaking method to study how these droplets transition from liquid to solid. This change plays a role in various diseases, including neurodegenerative…

Antibiotic resistance is an economic problem. Pharmaceutical companies cannot earn much from antibiotic research, so they do not invest in it. This makes it important that universities do so, says Ned Buijs.

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.

Bacteria whirl around in the mouths of most people, forming dental plaques and sometimes causing nasty gum infections. Treponema denticola might be a dangerous pathogen, but not much is known about this bacterium. It was up to Ariane Briegel and her research group to change that.

Before researchers can develop targeted drugs, they need to know exactly how a disease works. Biochemist Bert Beerkens created molecules that allow them to find out. He used caffeine as the basis for new molecules that enable research into certain receptor proteins on cells.

Giving an incorrect answer as a student in a packed lecture hall can be nerve-wracking. But with Pharmacology teacher Rob van Wijk, you don’t need to worry about that. ‘He creates a comfortable and safe atmosphere,’ his students say. They have nominated him for the Leiden Science Teacher Award.

The right medicine in the right dosage for every patient, that is something medical science aspires. 'Personalised medicine' is the term for that. But it does require a lot of research with patient data and that can be hard to get due to privacy legislation. Researchers Laura Zwep and Coen van Hasselt…
