Physicists and vision scientists are lining up behind a provocative claim: the rich color we call purple is not a property of light at all, but a story the brain tells itself. Light in the real world ...

a) Illustration of the omnidirectional wavelength-tunable color device featuring a mechanochromic chiral liquid crystal elastomer (CLCE) and an electrically deformable dielectric elastomer actuator ...

Color is determined by a wavelength, your eyes, and your brain. What are light and color? It all starts with the Sun. The Sun puts out a lot of different waves of light, some of which we can see with ...

Assessing animal welfare is necessary from animal behavior and product quality/quantity perspectives. Birds have a unique visual system and see in the range of 315-750 nm. Most of their behavior is ...

Researchers have synthesized a collection of nanoparticles, known as carbon dots, capable of emitting multiple wavelengths of light from a single particle. Additionally, the team discovered that the ...

Researchers have designed a new chip-integrated light source that can transform infrared wavelengths into visible wavelengths, which have been difficult to produce with technology based on silicon ...
