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…

Hans Ulrich Scherer is Professor of Rheumatology, in particular Translational Rheumatology. He wants to build bridges between research and clinical practice and between departments and organisations at home and abroad. Scherer will give his inaugural lecture next Friday. ‘To make progress, we have to…

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…

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.

When we think of unethical medical experiments, we tend to think first of Nazi Germany. What is less well known is that experiments were also carried out in colonised areas without the explicit consent of the test subject. University lecturer Fenneke Sysling has received a European grant to 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.

Due to the increasing resistance to certain antibiotics, the life-threatening condition sepsis is becoming harder to treat. For her PhD project, Leiden pharmacologist Feiyan Liu used mathematical modeling to find out how antibiotics can be used more effectively to cure sepsis.

On July 28, 2022, our dear colleague Daniëlle Hamstra passed away after a short sickbed. Daniëlle had been associated with the Clinical Psychology Section since 2010, initially as a student in the research master's program and subsequently as a lecturer and PhD candidate.

Last month, research by the National Institute for Public Health and the Environment (RIVM) revealed that more than half of students in higher professional education and at universities experience psychological complaints and emotional exhaustion, and that a quarter of them suffer from anhedonia (loss…

The steady decline in lethal gun violence in the EU came to halt in 2012 and some countries, such as Sweden, have even noticed an increase since then. An arms race among drug criminals and an increase in the availability of illegal firearms could lead to more criminal and gun violence. This is one of…

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.

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.

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…

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.
