Researchers at Cambridge and Meta developed a new method to measure human visual resolution, revealing that the human eye can perceive higher resolutions than previously thought in grayscale, but less so in color, which has implications for display technology and consumer choices.
Scientists from the University of Cambridge and Meta found that for typical viewing distances in an average-sized living room, ultra-HD TVs (4K or 8K) do not provide a noticeable improvement in image sharpness over 2K screens, as the human eye cannot distinguish the extra pixels beyond a certain point.
Scientists are studying the freshwater apple snail's remarkable ability to fully regenerate its eyes after amputation, using genome editing techniques like CRISPR-Cas9, with the goal of applying this knowledge to help humans recover from eye injuries due to the structural and genetic similarities between snail and human eyes.
Researchers at Penn State have developed a device that mimics the human eye's ability to see color using narrowband perovskite photodetectors and a neuromorphic algorithm. The device generates electricity as it absorbs light, potentially leading to battery-free camera technology. The technology may bypass the need for filters used in current cameras, which reduce resolution and add to manufacturing complexity and cost. The findings could also trigger further developments in artificial retina biotechnology.
