Even minor disruptions in infrastructure systems can have fatal consequences. Researchers and practitioners counter that risk by taking action on multiple levels. Four examples.

Disruption has the power to upend our lives. But approached constructively, disruption and resilience can be positive.

We register disruptions as a deviation from our expectations. We often experience this as a moment of uncertainty or as frustrated expectations. Does this mean that disruptions are always a bad thing? The philosophical essay explores these questions.

As Chair of the National Science Task Force, Martin Ackermann has to perform a constant balancing act between science, politics, the media and society. So how does he do it?
