MIT researchers have developed a bionic knee that integrates directly with muscle and bone tissue, aiding individuals with above-the-knee amputations in walking faster, climbing stairs, and navigating obstacles more easily than with traditional prostheses. The new system, anchored to the bone and controlled by the nervous system, offers improved stability and functionality. In a small clinical study, participants reported better performance in tasks like stair climbing and a stronger sense of the limb being part of their body compared to traditional prostheses. The technology will require larger trials for FDA approval, a process expected to take around five years.

People with blindness can read again after retinal implant and special glasses

A study published in the New England Journal of Medicine revealed that people with advanced dry age-related macular degeneration (AMD) regained the ability to read with the help of a retinal implant and specialized glasses. The PRIMA device, implanted in the eye and paired with augmented reality glasses, transmitted visual information to the brain, resulting in significant visual improvements for 80% of participants. While some patients experienced side effects, the technology represents a breakthrough for those with geographic atrophy. Future iterations of the device aim to enhance visual resolution and expand capabilities to include gray-scale natural images.
