Real-time video recording an 8×6-inch stretch of structural color pattern featuring a wreath in homage to the work of 19th century physicist Gabriel Lippmann. Real-time video recording an 8×6-inch stretch of structural color pattern featuring a wreath in homage to the work of 19th century physicist Gabriel Lippmann. The bright colors in butterfly wings or beetle shells come not from any pigment molecules, but from how they are structured—a naturally occurring example of what physicists call photonic crystals. Scientists can manufacture their own structurally colored materials in the laboratory, but it can be a challenge to scale up the process for commercial applications without compromising optical precision. Now MIT scientists have adapted 19th-century holographic photography techniques to develop a chameleon-like film that changes color when stretched. This method can be easily scaled while maintaining nanoscale optical precision. They describe their work in a new pap

Enhance your photography with an in-depth look at the star explosion effect. Learn what settings and approaches you need to capture beams of light, and how Star Filter Kit is your goal for creative brilliance. What is the effect of a star explosion? ‘Diffraction’ is a photographic term you may be familiar with. Otherwise, diffraction basically means scattering of light. As photographers, we understand this optical phenomenon as a bad thing because it is associated with a loss of sharpness. But diffraction is also responsible for creating the dreamy starburst effect in photos where the sun or a harsh light source creates a pointed beam of light. What does aperture have to do with the starburst effect? The starburst effect in photography is largely controlled and determined by your aperture, and more specifically, your aperture blade. If you ask two photographers to capture the same sun, they will likely produce different starburst effects due to their choice of lenses and the numb

Physicists have created an extraordinary phase of matter never seen before in a quantum computer. Physicists demonstrate a less error-prone way of storing quantum information by subjecting quantum computer qubits to quasi-rhythmic laser pulses based on the Fibonacci sequence. Physicists have created an extraordinary, never-before-seen phase of matter by shining a sequence of laser pulses inspired by the Fibonacci sequence on atoms inside a quantum computer. Although there is still only a single time stream, phases have the benefit of two time dimensions, physicists report July 20 in the journal. Natural . This mind-bending property offers a much-desired benefit: Information stored in phases is much more protected from error than the alternative settings currently used in quantum computers. As a result, information can last longer without becoming garbled, an important milestone to create quantum computing Perform computations using quantum mechanical phenomena such as superposition a

Japanese researchers have released plans to recreate Earth’s gravity level on the moon. The effort aims to support plans by the United States and other countries to build long-term bases for humans on the moon. The low gravity on the moon will affect the humans living there in important ways. The American space agency NASA notes that the gravity on the moon’s surface is one-sixth the gravity we experience on Earth. How to “make” gravity Designers working on plans to recreate Earth’s level of gravity, known as “1 g,” on the moon proposed the use of a centrifugal system. Centrifugal force is created by circular motion. The centrifuge rotates very fast to force the material in it away from the center or axis point, NASA explains. This planned system will create false gravity in the enclosed space on the lunar surface. The project is a partnership between researchers at Japan’s Kyoto University and engineers at Japanese building company Kajima. The researchers say the centrifugal sys
