Op 3 oktober streed een team van het Instituut Biologie Leiden tegen andere universitaire biologenteams in de Biology Battle of the Universities. Het team behaalde de tweede plaats.

Prof.dr. Geert de Snoo is per 1 maart bij de Faculteit der Wiskunde en Natuurwetenschappen benoemd tot hoogleraar Conservation Biology. De Snoo blijft hoofd van de gelijknamige afdeling van het Institute of Environmental Sciences (CML).

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…

In het kader van de Honours Course ‘Crises in Biology’ die plaatsvond van 19 augustus t/m 2 september 2012 in Normandië, bezochten studenten vele geologische interessante locaties. Een van deze bijzondere plekken was de kust van Arromanches. Hier bemachtigden zij een enorm grote ammoniet die ze dinsdag…

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.

Barry White wist het, en mannetjeskoolmezen weten het ook: wil je scoren bij de dames, dan moet je zo laag mogelijk zingen. Maar om boven stadslawaai uit te komen zijn hoge noten juist beter. De Leidse bioloog Wouter Halfwerk onderzocht de rol van toonhoogte bij communicatie tussen stadsvogels. De onderzoeksresultaten…

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

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?

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

As a non-invasive genetic method, eDNA based approaches have become an important component of ecologists' and environmental managers' toolkits for biomonitoring in conservation and an increasingly important source of ecological knowledge.

Does the presence of Ring-necked parakeets negatively influence feeding and feeding behaviour of native bird species on artificial bird feeders and if so, what are possible solutions?

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

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

The power of personalized nutrition lies in being able to conduct clinical research on healthy people while capturing metabolic markers sensitive to the impact of environmental and metabolic stressors (e.g. diet, changing sex hormones and the menstrual cycle).

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

Anthropogenic noise has been shown to affect marine animals in various ways, this may have fitness consequences at individual and population level. This thesis aims to increase insight into the quantification of sound-induced behavioural responses that are relevant to fitness, and into factors that…

This thesis describes the synthesis and biochemical evaluation of a variety of cyclophellitol based activity-based probes and inhibitors targeting various endo- and exo-acting retaining glycosidases. In the last two decades a variety of probes and inhibitors for (hemi)cellulose degrading enzymes have…
