A team of European astronomers has found a silicate-based weather system on a cloudy gas planet around the star WASP-107. It is the first time astronomers have found silicate clouds and rain. They also conclude that temperatures deeper in the atmosphere are rising rapidly. 'The presence of clouds has…

In order to stop a whole range of diseases or disorders at their source, you would have to be able to switch certain genes on or off. Sebastian Pomplun wants to develop substances that can do this very precisely. For example, he wants to disrupt cancer processes and make cells produce an important missing…

Smart drug carriers, uneven cosmic expansion, and solar energy storage in molecules. These are the topics of three newly awarded NWO-XS grants to researchers at the Faculty of Science.
