Editor’s summaryAs autonomous systems are increasingly deployed in various real-world scenarios, the ability to safely accomplish their desired tasks is dependent on the ability to detect system failures and subsequently take the appropriate action without human intervention. Ragan et al. have developed a method—safe fault estimation via active sensing tree search—for diagnosing system faults capable of planning and acting to ensure safe robot operations.

Editor’s summaryMany biohybrid robots are powered by animal or plant cells, which are sensitive to specific culture procedures and limited to short life spans. In contrast, fungi can be easily cultured and are robust in extreme conditions. Taking advantage of fungal mycelia’s natural light sensitivity, Mishra et al. developed an electrical interface to both house the mycelia and measure their electrophysiological action potentials.
