Peregrine falcons have the fastest vision among birds of prey, registering up to 129 Hz blinks per second for high-light conditions. This exceptional visual acuity allows them to track fast-moving prey like flying birds and small mammals.
Researchers at Tokyo Institute of Technology have discovered a way to make submicron-sized cylinders disappear using optical frequency illumination. This breakthrough could lead to new kinds of detectors and sensors for the medical and aerospace industries, without the need for expensive metamaterial coatings.
Researchers at Penn State and MIT discovered that uniform-sized clear water droplets on a surface can produce bright iridescent colors. The color is due to total internal reflection and light interference, creating an optical effect not possible in perfect spheres.
Researchers at Lund University developed a method to control extreme UV light using strong laser pulses, allowing for precise manipulation of electron dynamics and light properties. This technique has the potential to revolutionize our understanding of light/electron interactions.
Researchers at NIST create a system to compare photon travel times with sub-femtosecond accuracy, finding significant differences in time it takes photons to pass through materials with different refractive layer arrangements. This technique could provide empirical answers to long-standing puzzles about light's behavior in narrow gaps.
Researchers validated Einstein's theory by applying information theory to laser experiments, showing that information cannot exceed the speed of light. The study found that fast light pulses did not travel faster than light speed, but rather were delayed slightly compared to vacuum speeds.
