Sometimes in the development of science and technology, serendipity and luck play a large part, such as the following:

Seeing in the dark could soon be as easy as popping a pill or squeezing some drops into your eyes, thanks to some new science, an unusual deep-sea fish, and a plant pigment.

In the 1990s, marine biologist Ron Douglas of City University London discovered that, unlike other deep-sea fish, the dragonfish Malacosteus niger can perceive red light. Douglas was surprised when he isolated the chemical responsible for absorbing red: It was chlorophyll. “That was weird,” he says. The fish had somehow co-opted chlorophyll, most likely from bacteria in their food, and turned it into a vision enhancer.
