[ad_1] The push for ever-smaller chips has been running into more and more obstacles, including the very limits of silicon — while optical connections would allow for denser, speedier processors by eliminating heat and energy issues, silicon is lousy at emitting light. Or rather, it was. Eindhoven University of Technology researchers have developed what they […]

[ad_1] Chameleons can change their colors thanks to photonic crystals in their skin. As they tense or relax their muscles, the light reflects in a different pattern, resulting in a change of color. The problem with synthetic color-changing skin is in the hydrogel that the photonic crystals are packed into: After expanding and contracting, the […]

[ad_1] Existing techniques for both studying light and extracting 3D info are inherently limited by the size of wavelengths. This allows a considerably higher resolution that can even include holographic movies of fast-moving objects. The approach is still very early and might not reach quantum computers for a long time. However, it does hint at […]
