  • Using a chip-based microcomb, full dimensional control of structured microwaves is demonstrated, including vortex-microwave generation, submicrosecond spatiotemporal mode switching, broadband phase–frequency response tuning and wide-angle two-dimensional beam steering. These capabilities are applied in a structured-microwave-based integrated sensing and communication system.

  • A unified optoelectronics platform comprising dual-comb generation, modulation and metasurface-enabled beam steering serves as a transmitter for any standards between 2G and 6G. This architecture reduces power usage and costs, enabling a direct link between edge data-centre devices and the wireless network.

  • IBS is a common gastrointestinal condition characterized by abdominal pain associated with altered bowel habits. Limited and judicious use of diagnostic testing is recommended, particularly in patients with typical symptoms without alarm signs and symptoms. Management of IBS is multifaceted and is often driven by illness severity, predominant symptoms and patient and practitioner preferences. Sarah Khan and Lin Chang discuss the current evidence-based recommendations for the diagnosis and management of IBS.
