Researchers behind a recent study claim to have discovered a new color that the natural, naked eye cannot perceive — 'olo,' a ...

The answer could be to give them human-like muscles. This was the goal of an MIT team, who created a muscle-like structure similar to a real iris using biological cell cultures.

similar to how the human iris dilates and constricts the pupil. The researchers are calling this method 'stamping,' because it involves 3D printing a stamp patterned with microscopic grooves only ...

There are more measurable characteristics in the iris, the visible coloured ring around the pupil, than in other biometrics. Every human iris is unique. Compared to other biometrics, iris recognition ...
