Niet-liberale staten en mondiaal bestuur
Na tientallen jaren waarin autocratieën in de meeste internationale organisaties werden gemarginaliseerd, hebben de opkomst van China, de steeds autocratischer wordende wending in Rusland en het toenemende belang van machten als hybride regimes geleid tot een nieuwe realiteit waarin diverse niet-liberale…

Long-term observation of protein dynamics via thermal-snapshot single-molecule spectroscopy
This dissertation revolves around the design and implementation of novel instrumentation and related measurement techniques, at the single molecule level, for use in biophysical research. Chapter 1 presents an introduction to the field of fluorescence-based single molecule measurements. In particular,…

Digging for data: the rise and fall of a Miocene mammal biodiversity hotspot in the Vallès-Penedès (Catalonia, Spain)
The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

Young suns and infant planets: Probing the origins of solar systems
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).

Radio galaxies near the epoch of reionisation
This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

Cold gas in distant galaxies
The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.
-
Measuring gold molecular gas across cosmic time
Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

Anthracycline biosynthesis in Streptomyces: engineering, resistance and antimicrobial activity
Actinobacteria are well known for the production of bioactive natural products, many of which have applications in the fields of human, animal and plant health. Subject of this thesis are the anthracyclines, glycosylated aromatic polyketides with potent anticancer activity.

Tuning in to star-planet interactions at radio wavelengths
Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

Inhibitors and activity-based probes for β-D-glucuronidases, heparanases and β-L-arabinofuranosidases
Glycosidases (GHs) are enzymes responsible for the degradation of carbohydrates and play many roles in human health and pathophysiology. Often, abnormal levels of glycosidase activity are markedly linked to human pathologies.

Impact of plant hormones on growth and development of actinobacteria
Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.
