Pathogenic bacteria are increasingly resistant to today’s antibiotics. Professor Gilles van Wezel seeks new forms of antibiotics in good bacteria that live in the soil.

A child who receives fewer nutrients in the womb than their identical twin brother or sister is more likely to have developmental problems later in life. This is what researchers from the Leiden University Medical Center (LUMC) write in The Lancet Child & Adolescent Health. This study shows that unfavourable…

Extremely painful chronic cluster headaches – sometimes referred to as ‘suicide headaches’ – can be prevented by stimulating the occipital nerve in the back of the head, according to research conducted by Professor Emeritus of Neurology Michel Ferrari from Leiden University Medical Center (LUMC). The…

Discovering effective new drugs is a long, expensive and uncertain process. Laura Heitman wants to improve this by finding out more about how drugs bind to proteins that play a role in disease. She calls it ‘drug discovery 3.0’. Inaugural lecture on 9 December.

People who have negative expectations about a treatment actually experience more pain. Merve Karacaoglu discovered in her PhD research that anxious and pessimistic individuals are particularly susceptible to this nocebo effect. However, this sensitivity comes with a silver lining.

Patients on patient forums share all sorts of things about their illness: from side effects and advice to messages of support. PhD candidate Anne Dirkson uses artificial intelligence (AI) to retrieve this information. ‘Ninety per cent of the side effects weren’t officially registered.’

Ecotox is a stimulating top-facility that provides an integrative research environment around the topic of ecotoxicological testing and experimental research. Research focus: Dose-response modelling Mode-of-actions and mechanism-of-actions Test method development, in view of targets in AOPs (adverse…

Researchers of the Leiden University Medical Centre (LUMC) and the Leiden Institute of Chemistry have made an important discovery about the commonly used anti-cancer drug doxorubicin. They have found a way to reduce its side effects without sacrificing the effectiveness of the medication. This is encouraging…

The Life in Custody (LIC) Study comprises a large-scale research project into prison climate and the quality of prison life in Dutch prisons.

In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…

The Dutch Government recently announced measures to limit the loss of purchasing power. These include, for example, raising the minimum wage and healthcare benefits. Another way for households to maintain purchasing power is to work more. Olaf van Vliet, Professor of Economics, explains the effects…

We are confronted on a daily basis with news about the Corona virus and its consequences. We read alarming headlines like 'Dutch becoming increasingly anxious about Corona virus' or 'Huge fears and stress about Corona crisis'.

In the online panel discussion of ESOF 2022 ‘The effect of the online world on adolescents’, together with Amy Orben, Professor Eveline Crone, Sterre van Riel, Professor Anne-Laura van Harmelen and Professor Jan Sleutels, Professor Ton Liefaard shared his research on adolescents and the online world…

Steering soil microbiomes for better crop quality: the holy grail to improve human health?

A multi-disciplinary approach to past lifestyles and cultural practices

Through his project we will unravel the global regulatory networks that control gene expression in Streptomyces bacteria and allow them to properly respond to major changes in the environment; we will then harness this knowledge to activate and identify novel antibiotics

LACDR, the Leiden Institute for Drug Research, developed better tolerated excipients to prevent adverse effects related to the surface of nanosized drugs such as vaccines. LADCR professor of Biopharmacy Matthias Barz and Polypeptide Therapeutic Solutions (PTS) are collaborating to develop processes…

Viktorija Kostadinova, from Macedonia and currently a second-year PhD student at the Leiden University Centre for Linguistics, has just returned after two and a half months at the University of Michigan: ‘It was a truly rewarding experience.’

How is interdisciplinary collaboration faring at Leiden University? And has disciplinarity been completely abandoned? I’d like to reflect on some concerns among colleagues and on our plans for the future.

The annual conference of the Global Transformations and Governance Challenges (GTGC) interdisciplinary research programme will take place in The Hague on 7-9 June. Why should you be there? ‘The problems in the world affect us all. This conference will be looking at planetary governance’, says programme…

Leiden University has a strong tradition in language teaching, in various settings: for instance in the BA and MA language and culture programmes, area studies programmes, international studies, minors and electives. Currently, 20 different languages are taught throughout different institutes and pr…

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

Drought, exacerbated by climate change, is becoming a serious issue in Dutch cities. This affects the availability of water for people, nature, and infrastructure. The Thirsty Cities project is the first large-scale initiative to investigate this phenomenon, involving dozens of knowledge partners and…
