U.K. Researchers Conclude Most Viewers Can’t Discern 8K (or Even 4K) Resolution
(Image credit: DirecTV for Business)Researchers in the U.K. have confirmed what many in the broadcast industry have known for years: most viewers have trouble detecting 8K—or even 4K—video resolution.
According to the researchers at the University of Cambridge and Meta Reality Labs, the human eye has a resolution limit: in other words, there are only so many pixels the eye can see. Above this limit, a screen is giving our eyes more information than they can detect.To calculate the resolution limit, the researchers conducted a study that measured participants’ ability to detect specific features in color and greyscale images on a screen, whether looking at the images straight on or through their peripheral vision, and when the screen was close to them or further away.
The precise resolution limit depends on a number of variables, including the...

Researchers create nanostructured 2D gold monolayers
Researchers at Lund University and Hokkaido University have achieved a significant advancement in nanomaterial engineering by creating nearly freestanding nanostructured two-dimensional (2D) gold monolayers. This development has the potential to transform various fields, including catalysis, electronics, and energy conversion.
Gold is a noble metal that forms solid three-dimensional (3D) structures, can exhibit extraordinary properties when in its 2D form, such as unique electronic behaviors and increased surface reactivity, which could lead to groundbreaking applications in catalysis and advanced electronic devices.
One of the primary challenges in producing 2D gold monolayers is stabilizing isotropic metallic bonds. To overcome this problem, the research team utilized a novel bottom-up approach complemented by high-performance computations.
This innovative method allowed them to produce macroscopically large gold monolayers characterized by unique nanostructured patterns, high thermal stability, and promising catalytic capabilities.
The team successfully grew these...
