Scientists discovered that dragonflies can detect red light in a way similar to humans. This could lead to new medical technologies.
Imagine being able to see colors that are invisible to humans. Scientists have found that dragonflies can do just that! They can detect red light, which is beyond the range of human vision. This discovery could change medicine and technology in many ways.
Researchers at Osaka Metropolitan University studied how dragonflies see the world. They found a special protein called an opsin that helps them detect red light. This opsin is very sensitive to light with a wavelength of around 720 nanometers, which is beyond what humans can normally see.
The scientists think that this ability to detect deep red light might help dragonflies find mates. To test this idea, they looked at how much light different surfaces reflect. They found that males and females reflect light in slightly different ways, which could be a way for them to recognize each other while flying.
What's even more surprising is that the way dragonfly opsins detect red light is very similar to how human opsins do it. This means that scientists might be able to use this discovery to create new medical technologies that can reach deeper into the body.
