Can we use indigenous microbial rice communities to reduce methane production in agricultural settings?

For the first time, a group of international and interdisciplinary researchers led by Karline Janmaat and her former MSc Student Chirag Chittar, have tested the several hypotheses on music simultaneously in a modern foraging society during their daily search for tubers – their staple food. They found…

How can we explain the popularity of the Spanish comedia nueva in the seventeenth-century theatre scene of the Low Countries?

If a new method has been developed to recognize and treat a (neuro-)psychological disorder or related behavioral factors, it cannot yet be used directly in clinical practice. First, the method should be evaluated, preferably in randomized controlled trials.

On a structural level, the properties featured by a majority of mechanical metamaterials can be ascribed to the finite number of soft internal degrees-of freedom allowing for low-energy deformations.

A core interest of our cluster members concerns processes of reception, transformation and (interlingual and intermedial) translation in medieval and early modern art, literature and media from diachronic and synchronic perspectives (in time, space, and between media).
