De Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO) heeft een Aspasia beurs van €200.000 toegekend aan prof.dr. Joanita Vroom. Met deze beurs gaat zij een nieuwe onderzoeks- en onderwijslijn ontwikkelen die zich richt op de lange-termijn dynamiek van materiële cultuur in de oostelijke Mediterranée…

Indigenous Latin American artifacts have attracted the interest of Europeans since the earliest moment of contact between Europeans and the Indigenous peoples of the Americas. The ERC-funded BECACO project uses an innovative multidisciplinary framework to investigate the provenance of ethnographic and…

In this thesis we use state-of-the-art observations and simulations to provide the best constraints to date on the HVS ejection rate and constraints on the stellar content and dynamics at the GC, including the progenitor binary populations and their star formation history.

The expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

Tin electrodeposition applications have rapidly evolved in the past 25 years.

Arithmetic geometry concerns the number-theoretic properties of geometric objects defined by polynomials. Mathematicians are interested in the rational solutions to these geometric objects.

Plants, are sessile organisms, have developed strategies to adapt to changes in their environment, in part by altering their growth and development.

Biopolymer sequencing with graphene edge-based tunnel junctions has the potential to overcome current limitations with the third generation of sequencing based on biological nanopores.

Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

This thesis investigates a pharmacological challenge model induced by Toll-like receptor 7 (TLR7) activation, focusing on skin inflammation and its implications for early drug development.

Our recent excavations have focused on the more recent New Kingdom/Late Period (ca. 1500-332 BCE) material.

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

De Saxion Hogeschool en de Faculteit der Archeologie van de Universiteit Leiden gaan samen een nieuwe masterspecialisatie Applied Archaeology in het leven roepen. Daartoe ondertekenden Anka Mulder (voorzitter CvB Saxion Hogescholen) en Hester Bijl (vice-rector Universiteit Leiden) op 22 januari een…

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

The research described in this thesis shows that hypercholesterolemia, a well-established risk factor for atherosclerosis, can impact skin lipid pool and barrier function already at young age. In the field of atherosclerosis, we showed that the small peptide Lyp-1 can be used as a targeting molecule…

Carbon dioxide capture and utilization technologies are necessary to create a truly circular economy. The electrochemical reduction of carbon dioxide to formate is an appealing carbon utilization method as it can be performed at room temperature and pressure, it only requires two electrons, and it has…

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

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).

De Leidse Faculteit der Archeologie heeft recentelijk haar eigen onderzoeksblog gelanceerd. In het Leiden Archaeology Blog delen onze onderzoekers hun activiteiten met collega's en het brede publiek.

Met een bachelorgraad in de archeologie kun je in Nederland aan de slag als veldarcheoloog. Je bent gekwalificeerd om deel te nemen aan de vele aspecten van opgraaf-, prospectie-, en verslagwerkzaamheden. Je hebt echter geen bevoegdheid om een leidinggevende rol te spelen of je eigen archeologisch project…

Op Cyprus gebruikten mensen voor 2400 voor Christus al koper. Het eiland was minder achtergebleven dan gedacht. Dr. Bleda Düring voert al enkele jaren opgravingen uit op het eiland. Zijn vondsten dragen bij de kanteling van het beeld van Cyprus als een geïsoleerde plek. Het NRC plaatste er een artikel…

Uit opgravingen in een neolithische nederzetting in Turkije blijkt dat mensen er bijzondere begrafenisrituelen op nahielden. Zo verfden ze de botten van doden. Kijk Magazine interviewde dr. Bleda Düring over dit fenomeen.

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.
