7.5 Wireless injectable device enables nerve control without surgery or batteries¶
Scientists at NYU Abu Dhabi partnered with Cleveland Clinic Abu Dhabi to develop a seed-sized injectable wireless device that controls nerve activity without surgery, batteries, or wires. Delivered through a standard needle and positioned near a specific nerve, the device sends controlled electrical signals to regulate nerve activity. Power is supplied wirelessly from outside the body, allowing real-time adjustment by doctors or patients. The technology can be located and monitored using ultrasound and CT scans.

7 Scientists discover hidden fluid drainage system in eye¶
Scientists at University of British Columbia and University of Toronto discovered a previously unknown waste-removal system at the back of the eye in mice, called the posterior ocular lymphatic outflow (POLO) pathway. This system drains fluid and waste from the retina into the body's lymphatic system. Accumulation of fluid and waste at the back of the eye is associated with glaucoma, age-related macular degeneration, and other blindness causes. The discovery could lead to new therapeutic approaches targeting this cleanup mechanism.
