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…

This thesis consists of three papers that are centered around the common theme of Hausdorff uo-Lebesgue topologies and convergence structures on vector lattices and on vector lattices and vector lattice algebras of order bounded operators.

Engelsen hebben een groot normbesef als het gaat om taal: in formele situaties hoor je beschaafd Engels te spreken. Toch zijn de meesten tijdens het dagelijks taalgebruik wel een stukje milder in hun oordeelen bepaalde zinsconstructies te vermijden. Dat blijkt uit een onderzoek van taalkundige Carmen…

Herken je dat: je ziet je vriend lachen, en plots begin je ook te grijnzen? Promovendus Chris Riddell doet onderzoek naar hoe en waarom we lichaamstaal kopiëren. Hij neemt je als nieuwe Face of Science een jaar lang mee in zijn onderzoek.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

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-…

There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…
