    In quantum materials, ultrashort light pulses can induce transitions between electronic phases, switch ferroic orders and unveil non-equilibrium emergent behaviours. Here, we review the use of femtosecond X-ray pulses in tracking the underlying dynamics of the structural, electronic and magnetic order in these systems.

    The field of soft wearable robotics offers the opportunity to wear robots like clothes to assist the movement of specific body parts or to endow the body with functionalities. Collaborative efforts of materials, apparel and robotics science have already led to the development of wearable technologies for physical therapy. Optimizing the human–robot system by human-in-the-loop approaches will pave the way for personalized soft wearable robots for a variety of applications.

    The discovery and development of advanced materials are imperative for the clean energy sector. We envision that a closed-loop approach, which combines high-throughput computation, artificial intelligence and advanced robotics, will sizeably reduce the time to deployment and the costs associated with materials development.
