Spinoza winner Marijn Franx to use successor to Hubble
A permanent exhibition on the place of humans in the cosmos. This is something Franx wants to use his Spinoza Prize for. ‘So much progress has been made that we are still trying to define the questions. In finding the answers we are constantly coming up against surprises.’

DEEPSEA SOUND: pioneer explorations into biological relevance and anthropogenic disturbance
Are there acoustic cues for settlement stage larvae in deep-sea soundscapes around hydrothermal vents?

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.

Exploring the Edge
At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

Segments and rules: a comparative study into the computational mechanisms underlying language acquisition
In this project we study the properties of statistical- and rule-learning mechanisms in relation to the acquisition and evolution of language. We ask to what extent these mechanisms are unique to humans - or to human language - by comparing the acquisition of vocal structure in two species: humans (infants)…

Revealing the nature of new low-frequency radio source populations
It has now been well established that shocks and turbulent motions in the intra-cluster medium (ICM) generated through cluster mergers can produce large-scale synchrotron emission.

Resolving a bioindicator diatom species complex using genomic approaches for freshwater biomonitoring
This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;

Microbial hitchhiking
How do nonmotile microbes leverage communal motility?

Correcting each other’s mistakes - why cells stuck together in early evolution
The transition from single cells to multicellular organisms was a key step in evolution. Researchers from Leiden and Amsterdam developed a mathematical model that explains how this transition may have come about. They suspect cooperating cells may correct each other’s mistakes. Publication in eLife…

The Evolution of Fangs, Venom, and Mimicry Systems in Blenny Fishes
Venomous animals serve as models for a variety of mimicry types. Michael Richardson (IBL) and his international colleagues find that a group of fishes (called fangblennies) evolved venom after the origin of their venom-delivering fangs.

DNAmarkerpoint
The main purpose of DNAmarkerpoint is to better understand the ecology, evolution and biodiversity through the study of ancient- and modern DNA.

Hybrid zone dynamics in amphibians
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.

Mechanistic studies of the water oxidation reaction with molecular iron catalysts
In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

Bayesian Inference for Gaussian Models
This dissertation studies the Asymptotics of Bayesian nonparametric inference for Gaussian linear models.

Artificial metallo-proteins for photocatalytic water splitting: stability and activity in artificial photosynthesis
Climate change is one of the largest challenges faced by humanity. To combat this research into alternatives to fossil fuels is ongoing. Dihydrogen is considered a good alternative fuel, since its burning only forms water.

New light on dark matter
An international team of astronomers has found an unexpected link between dark matter and visible stars in stellar systems. This discovery may even cause us to reconsider our understanding of gravity. They published on their discovery in 'Nature' on 1 October.

Cultural evolutionary modeling of patterns in language change. Exercises in evolutionary linguistics
This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

To the edge of space and time
Large telescopes can look so deep into the Universe that they can also look back billions of years in time. From 2018, the successor of the Hubble Space Telescope, the James Webb Space Telescope, will be able to see the period just after the Big Bang, when the first stars and galaxies formed. Astronomers…

Cosmic tomography with weak gravitational lensing
We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.
