This thesis describes the development and optimization of the first molecular tools to study the enzyme PLA2G4E.

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

Evolution is all around you every day. This is the message of a Massive Open Online Course (MOOC) of Leiden University and Naturalis that is offered free of charge to anyone interested.

Evolution is all around you every day. This is the message of the new Massive Open Online Course (MOOC) of Leiden University and Naturalis that begins on September 19.

Lichens enthusiast Sander van Zon was eager to use his knowledge for his internship. He wrote an excellent thesis on lichens’ biodiversity in the city, of which his first scientific publication will appear soon. With it, he is nominated for the Leiden Science Young Talent Award 2022.

To explore the potential of marine microorganisms as producers of novel antimicrobial agents and as bioprotectants in aqua- and agriculture, using an integrative, ecology-based strategy for bioprospecting.

In this thesis, the discovery and optimization is described of chemical tools to study the N-acylethanolamine (NAE) biosynthetic pathway.

‘Make more room for nature on farmland and you'll be surprised at the result.' This was the advice from Geert de Snoo in his Dies lecture.

Short description about 20th anniversary of CEDC, the fieldstation in Cameroon, and 20 years of cooperation between Leiden University with the University of Dschang in Cameroon.

Actinobacteria are Gram-positive bacteria that have a complex multicellular life cycle and are well known for their ability to produce a wide range of bioactive natural products (NPs).

This thesis explored the molecular pharmacological mechanisms of targeting CB2R via investigation of novel drug discovery concepts such as target binding kinetics, allosteric modulation and biased signaling.

‘Wadden Sea Sounds’ is the name of a new project launched by the Waddenvereniging in collaboration with researchers from Leiden University and the University of Groningen. The aim is to find out how underwater noise affects marine life in the Wadden Sea.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

The dark matter of biology: clumps of sugar molecules that, for example, form sugary webs around pathogens. We know very little about them. Wouter Remmerswaal threw all his talent into the challenge – both in the lab and as a modeller – and succeeded. He received his PhD on 12th September.

An evolutionary 'trap' that has haunted crested and marbled newts for 25 million years: Leiden researchers have uncovered a mysterious DNA error that should not be able to arise – yet persists all the same. How is that possible? PhD candidate James France found new clues.

Merijn de Bakker and colleagues of the IBL-research group of Prof. Mike Richardson provide a unique view on digit evolution in crocodiles and birds in their recent study published in Nature.

Marie-Jeanne Holveck and Katharina Riebel from Behavioural Biology at the Institute of Biology at the Faculty of Science published their research in Proceedings B of The Royal Society.

Biologists today have to be able to work with big data. Data analysis skills should be taught from the start of the degree programme, or - even better - in secondary school. This is the message of Vera van Noort, new Professor of Computational Biology. Inaugural lecture 22 January.

Roeland Merks is appointed as professor Multiscale Mathematical Biology (0.2 FTE) at the Mathematical Institute as from 15 January 2014.

The ‘Stans Prize 2010’ has been awarded to Leontien Cenin and Lisanne Daniëlle Korpelshoek for their research on impacts of landuse on three migrant harriers in northern Cameroon.

Nine students dove into a challenging iGEM project this summer. With their idea, they aim to make antibodies more efficient - and in the meantime learn at least as much about collaboration, creativity and their own future.

The Leiden students who participated in the iGEM synthetic biology competition have won the prize for best production. They developed a way to have bacteria produce the substance suckerine, a protein derived from the Humboldt squid. By doing so, they want to help heal burn wounds. ‘The announcement…

The Leiden mathematics student Onno Berrevoets won the silver medal during the last edition of the International Mathematics Competition in Blagoevgrad in Bulgaria. During this prestigious competition between mathematics students worldwide, he was able to measure himself to the world top.

In 2023, many of our students and staff won great prizes and secured important research grants.

“Temminck’s Order” is the scientific biography of Coenraad Jacob Temminck (1778–1850), a Dutch naturalist and the first director of ’s Rijks Museum van Natuurlijke Historie in Leiden.

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

Songbirds apparently use mnemonics rather than more complex grammatical rules to recognise structures in which they have been trained. Leiden behavioural biologist Caroline van Heijningen published an article on this subject on Tuesday 17 November in PNAS.

The Ig Nobel prize is awarded annually to ten studies that first
