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…

Can we distinguish the effects of pesticides from other abiotic and biotic factors that occur in the field? And how do these factors interact with pesticides?

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.

New research published in the Journal of Leukocyte Biology suggests that these changes to the behavior of the immune system are persistent and can continue even after diet is improvedAlmost everyone knows that improving your eating habits will most likely improve your health. What most people may not…

Leiden Biology student Pam Engelberts received the annual award for being the best BSc-student in 2016 from the “Stichting Professor Dr. K. Bakker-fonds”.

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

The Science faculties of Universitas Indonesia (UI) and the Universiteit Leiden signed agreements on Tuesday April 12 that will strengthen cooperation between the Faculties. The agreements were signed at the closing of a two day visit of a delegation from Indonesia. The delegation, which was led by…

Do sustainability values play a role in motivating people to act for biodiversity in successful projects and in successful leadership action? And how could these values be incorporated in current economic valuation methods?

On December 4th, Flor Rhebergen received the 2015 Unilever Research prize for his study achievements at the IBL for his outstanding work in the field of Evolutionary Biology. Flor Rhebergen received the “Ovum” sculpture and was awarded €2.500.

The new institute manager of the IBL studied biology for six months, but went in a completely different direction: development cooperation and the financial sector. Three decades later, Resi Janssen is making a radical career switch. Or isn’t she? 'In ten years’ time I want IBL to be in a new, sustainable…

How has early development in R. ocellatus been modified as a result of its parasitic embryonic lifestyle?

Large carnivore population is globally declining as a result of the fragmentation of habitat, large prey depletion and retaliatory killing by pastoralists.

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

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.

Influenza CD8(+) T-cell epitopes are conserved amongst influenza strains and can be recognized by influenza-specific cytotoxic T-cells (CTLs), which can rapidly clear infected cells. An influenza peptide vaccine that elicits these CTLs would therefore be an alternative to current influenza vaccines,…

What is movements and corridors of the Bornean pygmy elephant in Sebuku forest? What is the nature of human-elephant conflict in Nunukan District in time and space? What are the diets of the Bornean elephants related to crop raiding?

This liber amicorum is a tribute to Prof. dr. ir. Hans H. de Iongh, associate professsor at the Institute of Environmental Sciences (CML) of Leiden University and guest professor at the University of Antwerp, on the occasion of his retirement on 27 October 2016.
