According to @ai_darpa, researchers have introduced "Circulatronics," a breakthrough technique that integrates AI-driven wireless microdevices with living immune cells to enable targeted, non-invasive brain repair. These gadgets, described in Nature Biotechnology (source: nature.com/articles/s41587-025-02809-3), harvest light energy and travel through the bloodstream, using immune cells as carriers. This allows them to autonomously access inflamed brain regions without surgery and wirelessly stimulate neurons with micrometer accuracy, as demonstrated in mice. The innovation signals a major opportunity for AI-powered neuromodulation therapies, particularly for Alzheimer's, multiple sclerosis, stroke, brain tumors, and chronic pain, offering scalable and minimally invasive solutions for neurological diseases.
