Na decennia van intensieve landbouw staat het veenweidegebied onder druk. In het Polderlab werken wetenschappers, boeren en beleidsmakers samen aan toekomstbestendige vormen van landbouw. ‘Het is ongelooflijk hoe snel het systeem opveert zonder intensieve bemesting.’

The aim of this workshop is to open up the discussion of textual communities in Late Antiquity and the early Middle Ages, by offering a platform for PhD students from all over the world and from various disciplines to present their own research and discuss it with others. Deadline: April 23.

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…

Begrijpen van het evoluerende landschap van extremisme in de 21e eeuw.

Thierry Rohmer ontving de Ernst Award 2009 van het Gesellschaft Deutscher Chemiker (GDCh) voor zijn publicatie in de Proceedings of the National Academy of Science van de VS op de structuur-functie relatie van de photoreceptor fytochroom. De prijs werd in september gepresenteerd op de jaarlijkse vergadering…

Europese burgers worden geconfronteerd met uitdagingen op het gebied van globalisering, migratie, technologische ontwikkelingen en klimaatverandering. Deze uitdagingen vergen het uiterste van onderlinge internationale en intergenerationele solidariteit, wat rechtstreeks betrekking heeft op de grondslagen…

Which traits and/or trade-offs determine benefits of being deciduous or evergreen?

De eerste index om de veiligheid, duurzaamheid en circulariteit van producten te meten, waarmee ze het EU-kader (SSbD) operationaliseren.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity.

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Pseudomonas Aeruginosa is a Gram-negative bacterium which can form biofilms, increasing its resistance against antibiotics and the host immune system. Polysaccharides are an integral part of this biofilm, one of these polysaccharides is called Psl. PslG is a glycosidase, able to cleave this polysaccharide,…

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

Sterrenkundigen onder leiding van John Tobin hebben dankzij nieuwe waarnemingen, verricht met de Amerikaanse Very Large Array-radiotelescoop (VLA), meer inzicht verkregen in het geboorteproces van meervoudige sterren.

Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

Arabische planten, lezingen en workshops rond de Arabische keuken en cultuur. Het 400-jarig bestaan van de leerstoel Arabisch in Leiden is aanleiding voor de Hortus botanicus om zich de hele zomer van zijn Arabische kant te tonen. Start: 25 mei.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

This thesis is an experimental study of the UV irradiation of the interstellar ice analogues, relevant for the different stages of the star and planet formation sequence.

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

In this thesis, we used genetically engineered mouse models to identify genes and pathways that are involved in ILC formation and in the development of resistance to FGFR-targeted therapy.

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.
