Gold Nanoparticles Could Restore Vision in People with AMD

Could a tiny dose of gold restore sight? Researchers at Brown University have developed a groundbreaking retinal prosthesis using gold nanoparticles and infrared light to bypass damaged photoreceptors in retinal disorders like macular degeneration.

This minimally invasive method successfully activated the visual system in mice, offering promising early evidence for future clinical applications. Learn how this innovative fusion of nanotechnology and neuroscience could revolutionize treatment for millions suffering from vision loss.

Artificial Intelligence is Reshaping Healthcare

As of October 2024, 3,000 patients had used Piction’s clinic. So far, it is available in Connecticut, Florida, Massachusetts, New Hampshire and Washington. The service is covered by several major insurance companies, or patients can pay $119 out-of-pocket for each consultation.

Eleni Linos, a professor of dermatology and epidemiology who directs the Stanford Center for Digital Health, and who has no connection with Piction, says: “I’m really optimistic about how this technology can help patients get the best care they can get, while at the same time helping doctors.” — Esther Landhuis.

Your Brain Can Learn To Ignore Annoying Distractions — Here’s How

The human brain can learn to filter out distracting or disruptive stimuli, such as a bright roadside billboard or a flashing online banner, through repeated exposure. Researchers from Leipzig University and Vrije Universiteit Amsterdam have demonstrated this effect using electroencephalography (EEG), showing that early visual processing in the brain changes with experience. Their findings were recently published in The Journal of Neuroscience.

Distractions tend to become easier to ignore after repeated encounters. This process, known as learned suppression, plays a key role in the visual system and complements our ability to consciously direct attention. In a series of EEG experiments with 24 participants of all genders, the researchers examined how learning affects attention to highly noticeable distractions, particularly when such distractions consistently appear in the same location.
