Secondary lymphedema, a chronic condition caused by lymph node removal during cancer surgery, leads to swelling, pain, and reduced mobility with limited treatment options. In a recent study, researchers from Japan developed a centrifugal cell stacking technique to create artificial lymphatic tissues that can restore lymphatic flow. When transplanted into mice, CeLyTs form functional lymph node-like structures that reduce swelling and promote lymph flow, offering a promising therapeutic strategy for lymphedema.

Large language models (LLMs) play a key role in advancing intelligent healthcare. While LLMs are increasingly applied in medical fields such as disease screening, diagnostic assistance, and health management, there are no evidence-based guidelines for assessing their effectiveness in healthcare. Now, researchers have developed a consensus that provides a systematic and evidence-based evaluation framework to assess effectiveness of LLMs in medical applications. The framework includes scientific evaluation metrics and procedures, providing guidance for model evaluators.

Researchers analyzed the performance of four material types to boost the efficiency of evaporative cooling systems, which are capable of reducing energy consumption by 70% compared to conventional systems

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.
