Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

The word ¨pyroptosis¨ can be understood as ¨fiery falling¨, which describes the bursting of pro-inflammatory signals from the dying cell. Our observations indicate that pyroptosis also ¨spreads like wildfire¨ and once a cell dies via pyroptotic cell death, neighbouring cells are more prone to die as…
