Fluorescence is typically associated with gases or liquids, but a team of chemists has conjured a new formula that gives solid materials that characteristic fluorescent glow.
There’s a certain patience required for studying sticky tape. Sure, sometimes experiments require peeling, but other times, researchers must simply sit around and wait for the adhesive to fail. These experiments are bringing scientists closer to something that doesn’t yet exist: a unified theory of tape.
For the first time ever, scientists have 3D-printed an array of light sensors onto an eyeball-shaped surface. Eventually, a scaled-up version of the device could restore vision to the blind, or even improve the vision of sighted people.
