Living night lights: Succulents that store sunlight and shine for hours

Scientists have created glow-in-the-dark succulents that can recharge with sunlight and shine for hours, rivaling small night lights. Unlike costly and complex genetic engineering methods, this breakthrough relies on phosphor particles—similar to those in glow-in-the-dark toys—carefully sized to flow through plant tissues. Surprisingly, succulents turned out to be the best glow carriers, with researchers even building a wall of 56 glowing plants bright enough to read by.
