Researchers at The Hong Kong University of Science and Technology (HKUST) have developed CarGAP, a groundbreaking chemo-optogenetic tool that uses vitamin B₁₂ and green light to precisely control gap junctions, the microscopic channels enabling direct cell-to-cell communication. This innovation allows on-demand closing and opening of these intercellular bridges, providing unprecedented spatiotemporal control over vital molecules and electrical signals. Demonstrated in both mammalian cells and living fruit flies, CarGAP provides a powerful new way to study development, immunity, and neural activity, with far-reaching potential for understanding disease mechanisms and advancing regenerative medicine.

A randomized crossover pilot study conducted by researchers at the University of Sherbrooke and the Research Centre on Aging in Quebec, Canada, investigated whether moderate-to-high-intensity aerobic exercise performed the day before chemotherapy could influence cancer-related fatigue and active versus sedentary behaviors in the days following treatment. The study, published in Translational Exercise Biomedicine (ISSN: 2942-6812), an official partner journal of International Federation of Sports Medicine (FIMS), provides preliminary evidence that pre-chemotherapy exercise is safe and may offer modest benefits for fatigue management.
