Koç University researchers have developed an ultra-thin, fully wireless retinal stimulation technology that could help address vision loss caused by retinal degenerative diseases. Led by Prof. Dr. Sedat Nizamoğlu, the international team designed a nanotechnology-based system that converts low-intensity near-infrared light into electrical signals to stimulate retinal neurons safely and precisely. Published in Science Advances, the study shows that the biocompatible nano-assembly produces strong and repeatable neural responses in retinal models without inducing cellular stress, toxicity, or harmful heating. By eliminating bulky electronics and using safer near-infrared light, the platform offers a promising alternative to existing retinal implants and may also be adapted for broader neuromodulation applications.

Lockdowns isolated teenagers from friends, disrupted their routines, and kept them at home with daily reports of bad news. So most people assume teenagers felt worse during COVID-19 lockdowns, but a Tokyo study shows the opposite. Scientists at Nagoya University and their collaborators tracked Tokyo teens through the pandemic and found they experienced depression less often during lockdowns than during normal school life. Published in PLOS Medicine, the study found two groups that experienced depression differently. Both felt better during lockdown, but brain scans showed biological differences between them. 

Multimorbidity is defined as the concurrent presence of two or more age-associated diseases within an individual, which often results in detrimental health outcomes. Immunosenescence, the gradual deterioration of the immune system associated with aging, constitutes a significant risk factor for the development of these conditions. Moreover, certain diseases may exacerbate immunosenescence, thereby establishing a self-perpetuating pathological cycle. This bidirectional interaction forms a complex pathological network that presents considerable challenges for both the investigation and prevention of multimorbidity. In light of these challenges, it is pertinent to consider whether a paradigm shift in research and intervention strategies—centered on protective factors or anti-aging mechanisms—could facilitate substantial advancements in this field. On October 13, 2025, a research team led by Associate Researcher Xiaolin Ni and Researcher Erping Long from the Institute of Basic Medical Sciences at the Chinese Academy of Medical Sciences published an article entitled "Centenarians: a model of immune resilience against multimorbidity" in the journal Life Medicine. By examining the mechanistic interplay between immunosenescence and multimorbidity and referencing the unique immune profiles of centenarians, the authors proposed a novel systemic therapeutic paradigm termed IMET. This approach focuses on the modulation and restoration of the immune microenvironment, thereby offering innovative research directions and intervention strategies aimed at mitigating the burden of aging-related multimorbidity.

A study by The University of Osaka reveals that people who have had COVID-19 are more likely to wear masks. This is driven not by fear, but by an increased awareness of being a potential "silent carrier." The finding suggests that public health messages based on patients' real experiences, highlighting the risk of asymptomatic spread, could be more effective in encouraging preventive behaviors in the general population for future pandemics.

A recent study has demonstrated that using standard cameras commonly found in everyday video calls, researchers can achieve high-precision assessment of cardiopulmonary coupling without requiring individuals to wear any sensors. This non-contact technology opens up new possibilities for future home-based health monitoring and telemedicine applications.
