Het gaat niet goed met de biodiversiteit in Nederland. Hoogleraar Natuurlijk Kapitaal Koos Biesmeijer combineert onderzoek met praktische adviezen: van het vergroenen van industrieterreinen tot oplossingen die geïnspireerd zijn op de hightech-natuur. Oratie op 9 maart.

In the Schouwburgstraat, LUGO is currently redesigning the back-garden in order to increase biodiversity and make it a more beautiful space. Throughout October 2023 until March 2024, we will be making changes to the garden with our team of volunteers.

Increasing the efficiency of gene targeting (GT) as a genome editing tool in plants has been an important goal in plant biotechnology.

The project Multimedia Research and Documentation of African Oral Genres: Connecting Diasporas and Local Audiences (Director: D.Merolla) focuses on multimedia as technology that allows scholars to share documentation and scientific knowledge with the cultural owners of the collected oral genres.

Het Europa Instituut van de Universiteit Leiden is één van de oudste academische instellingen gespecialiseerd in het recht van de Europese Unie en het Europees Verdrag inzake de Rechten van de Mens.

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

De staf van het Europa Instituut bezit een uitgebreide expertise omtrent het recht van de Europese Unie en de Europese bescherming van de mensenrechten in het algemeen.

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

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

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

Planets are formed in disks of gas and dust around young stars.

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

Cardiovascular syndromes are the major cause of death in Western societies.

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

Atherosclerosis is a progressive disease resulting in the formation of an arterial plaque. Despite lipid lowering, recurrent cardiovascular events remain a risk. While atherosclerosis is primarily lipid-driven, the immune system plays a critical role in the pathophysiology.

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.

Sustainable energy from wind and solar is most readily available near the sea.

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

Like a mixture of oil and water, lipid membranes separate into two liquid phases.

Nucleoid associated proteins maintain the architecture of the bacterial chromosome and regulate gene expression, hinting that their role as transcription factors may involve local three-dimensional chromosome re-modelling.

De Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO) heeft landelijk 159 jonge, recent gepromoveerde onderzoekers een Veni-subsidie toegekend. 19 onderzoekers zijn verbonden aan de Leidse universiteit, waarvan 5 aan de Faculteit der Wiskunde en Natuurwetenschappen. Elke onderzoeker krijgt…

Twee Leidse onderzoeksprojecten die zich focussen op het vergroten van de biodiversiteit van het Nederlandse productiesysteem voor voedsel en sierteelt, kunnen van start dankzij financiering binnen de KIC-call van NWO.

Planten zou je kunnen zien als kleine chemische fabrieken, die via fotosynthese chemische stoffen produceren. Als we fotosynthese kunnen nabootsen in een kunstmatig systeem, kunnen we schone brandstoffen en materialen maken uit zonlicht en CO2. Huub de Groot is heel dicht bij het ontwerpen van zo’n…
