It is the dream of Professor Susana Chuva de Sousa Lopes to grow fertile egg cells in the lab. But she says there is a long way to go in her discipline until that is possible. This is the message of her inaugural lecture on 29 June 2020, the first digital inaugural lecture at Leiden University.

The Leiden iGEM team has won the grand prize at the iGEM international biology competition. The students won a further five prizes, including those for best diagnostics tracks and best inclusion. ‘We still can’t believe it. It feels almost surreal,’ team member Amber Schonk said yesterday to University…

How does the extracellular matrix coordinate endothelial cell behavior during angiogenesis, and how do metabolic waste-products and matrix-degrading enzymes produced by the tumour modify the extracellular matrix so as the change the cellular coordination?

During the spring of 2021, a group of eight biology students from Leiden set out into the dunes in search of amphibians. Using DNA, they determined the geographic origin of the animals. And guess what? In many cases they discovered exotic populations of animals that do not naturally belong in The Netherlands.…

Gayathri Jaikamur has been awarded by the Dopper Foundation in the Change Make Challenge. She is a student of Masters Biology (Specialisation: Evolution, Conservation and Biodiversity) from India - working under the supervision of CML-researcher Dr. Thijs Bosker (and co-supervision of Dr. Nadja Brun).…

This project is situated within the context of an innovation of the biology curriculum in Dutch secondary schools. The main purposes are (1) to clarify the relation between teachers’ practical knowledge and the decisions they make when planning and implementing their lessons and (2) to develop a professional…

The cannabinoid receptor type 2 (CB2R) is associated with several inflammatory diseases with an unmet medical need (e.g. Alzheimers, multiple sclerosis, reumatoid arthritis). Development of new chemical biology strategies to study this protein is essential to aid future development of drugs for these…

Professor emeritus of Animal Behaviour Carel ten Cate is awarded honorary membership by the Dutch Society for Behavioural Biology (NVG). He received the honour for his activities for the Society and the discipline of behavioural biology.

Please note that the course Molecular Biology for Physics will start on Monday 5 February. Please check the schedules for the time and location!

From 1 October, two new Directors of Education will start at the Institute of Biology Leiden (IBL). Dennis Claessen as the new director for the master's programme of Biology and Marcel Schaaf as director for the Biology bachelor's programme. Claessen and Schaaf have been appointed for a period of four…

Martijn Verkuilen is the winner of the Unilever Research Prize 2022. By transferring DNA from a plant into yeast, he made the first move to produce a new drug for type 2 diabetes. He collected his prize in Wageningen on 24 November.

In Leiden University's video series on Leiden and The Hague as student cities, students interview each other at their favorite spots. In the fifth video of this series, archaeology student Azra spoke with Biology student Floris in Naturalis Biodiversity Center.

Biosynthetic gene clusters (BGCs) for natural products are widespread in microbial genomes, and they are rapidly exchanged. This research assesses the factors that control the spread of BGCs and resistance genes in nature. This includes risk assessment for the spread of engineered DNA in nature.

A structural investigation of coiled coil peptides used as membrane fusogens, mimicing naturally occuring coiled-coil fusion proteins. Synthetic modifications have been made to alter lipid attachment, secondary structure and to insert photoactive azobenzene moieties for active control over coiled coil…

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

Tackling key challenges of Chemical Biology and Medicinal Chemistry to aid drug discovery is one of the focus areas of Leiden University. To this end, the Leiden Early Drug Discovery & Development network (LED3) was established by the Leiden Institute of Chemistry (LIC), the Institute of Biology Leiden…
