What do you think of trees that glow like streetlights?

Imagine a place that is so dark that you close or open your eyes the same way because there is no sunlight. While struggling, you see a light. Approaching to see clearly, a beautiful green light makes you wonder feeling worried. But no, you're wrong, the Anglerfish is waiting for you and swallows you right away. And this is just a part of bioluminescence.

Bioluminescence is the ability to self-emit light in some organisms. In one way or another, bioluminescence helps organisms increase their viability. For example, fireflies, the ability to shine blue light, help them attract mates on warm summer nights, but they are just one of the creatures that can glow.

Next is the deep sea shrimp (Acantherphyra purpurea). When feeling threatened, they spew out a cloud of glowing fluid. Who doesn't run away after being vomited up by someone else? Moreover, that fluid will attract larger predators.

So, what if I can't glow by myself? No problem! There are other ways for organisms to take advantage of bioluminescence even if they do not have this ability. Back to the case of the devil fish, the bait that glows on the top of its head is actually a leather bag containing bioluminescent bacteria. Because it cannot emit light on its own, the demon face has its own bag of luminescent bacteria.

Remember the fireflies?Fireflies really have the ability to glow by themselves. Inside the firefly's belly are two chemicals, Luciferin and Luciferase . When these two substances combine in the presence of oxygen along with the cellular ATP fuel, this chemical reaction releases energy in the form of light.

Through numerous studies to find out how fireflies make Luciferase and Luciferin, scientists have used genetic engineering to create light-producing reactions in even non-glowing organisms. For example, they transplanted firefly genes into tobacco plants. After a successful transplant, tobacco plants grow with the ability to glow like a Christmas tree.

Planted along the highway, these trees can light roads with only oxygen and other clean resources.

Unlike sunlight or incandescent light bulbs, bioluminescence does not generate heat, so the organism will not be harmed. And unlike glow sticks that turn off after using all the chemicals inside, bio-light uses an additional source of energy. That's why engineers are working on developing bioluminescent trees.

Think along the highway, these trees can light the road with only oxygen and other clean, free and readily available resources. This can save a lot of resources and help our planet survive longer. Do you think of any other ways to take advantage of biological light?
