All crested and marbled newts (the genus Triturus) suffer from an unusual genetic abnormality, called a balanced lethal system, that kills exactly half of their offspring. How can a trait so disadvantageous have survived millions of years of natural selection?

De tweede geheel vernieuwde editie van 'The E-Primer' bespreekt hoe een breed scala experimenten kan worden geprogrammeerd in E-Prime 3. E-Prime is een van de meest gebruikte softwarepakketten voor het ontwerpen van psychologische experimenten.

Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

Artful Mathematics: The Heritage of M. C. Escher

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

The ultimate goal of cosmologists is to find a cosmological model able to explain the current observational data.

Obesity may alter how a person absorbs, distributes, metabolizes or excretes medication. This thesis describes how obesity affects drug levels in the blood for antimicrobial agents, such as ciprofloxacin and fluconazole.

Bacteria have the ability to alter their morphology in order to adapt to changing environments.

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Over several decades, a variety of computational methods for drug discovery have been proposed and applied in practice. With the accumulation of data and the development of machine learning methods, computational drug design methods have gradually shifted to a new paradigm, i.e. deep learning methods…
