The results offer an important wake-up call for people who want to keep their brain sharp as they age.

Early-stage disease diagnosis relies on the highly sensitive detection of biomarkers. Optical whispering-gallery-mode (WGM) microcavity sensors have emerged as a highly promising technology for precise, label-free biosensing. However, major challenges remain in the rapid fabrication of large-scale arrayed WGM microcavity sensors and their integration into lab-on-a-chip devices for biomedical applications. In a noteworthy advance, researchers at The Hong Kong Polytechnic University (PolyU) have developed a novel 3D micro-printed WGM microlaser sensor for highly sensitive on-chip biosensing. This innovation drives the development of next-generation biosensing tools, enabling direct, ultrasensitive and quantitative measurement of biomarkers for early disease detection.

Researchers in Israel have detailed the experience of one hospital’s radiology department during the mass casualty incident following the October 7, 2023, attack in southern Israel, to provide recommendations for future crisis preparedness, according to a new study. The findings underscore the critical importance of in-hospital triage protocols, rapid staff mobilization and versatile imaging resources management.
