Scientists have discovered that the ancestor of fireflies 100 million years ago is different from or

The difference should be that the amount of light they have is different, in fact, the meaning of their light is not the same now.

Compared to fireflies of similar taxonids, it has larger eyes, a more protruding head, and a softer body. What's more special is that the glowing part of the firefly is now located at the end of the abdomen, while the luminous part of this ancient bug is more anterior, located at the front of the abdomen.

There is a certain difference in appearance, this firefly ancestor will have a longer body size, and there are tentacles, and the firefly ancestor will shine a little forward, in front of the abdomen.

There is still a certain difference, the fireflies at that time had larger eyes, and then the position of the head was also more forward, and the body was softer.

People according to fireflies.

Invented cold lights, fluorescent clothing, luminous clothing, etc. It is said that as early as the 40s, someone invented the fluorescent lamp through the study of fluorescent insects.

Later, through continuous research and innovation, the flash light was invented. In short, there are many inspiring plants and animals in nature, which allow people to create many new and interesting products.

The luminescence principle of fireflies:

Fireflies have specialized light-emitting cells, and there are two classes of chemicals in the light-emitting cells, one called luciferin and the other known as luciferin.

Enzyme. Luciferin can consume ATP under the catalysis of luciferase and react with oxygen, producing an excited state in the reaction.

Oxidized fluorescein, which releases photons when oxidized fluorescein returns from the excited state back to the ground state.

Almost all of the energy released in the reaction is released in the form of light, and only a very small part is released in the form of heat, and the reaction efficiency is 95%, so the beetle will not overheat and burn. So far, humans have not been able to create such an efficient light source.

There are many white patches on the lower part of the abdomen. In fact, it is the part of its carapace that is transparent to light. On the inside there is a white film that reflects light. So during the day this part appears white.

From fireflies to artificial cold light;

Since the invention of electric light, life has become much more convenient and richer. But electric light can only convert a small part of the electrical energy into visible light, and most of the rest is wasted in the form of heat, and the heat rays of electric lights are harmful to the human eye. So, is there a light source that only emits light but does not heat up?

Humanity has turned its attention to nature again.

In nature, there are many organisms that can emit light, such as bacteria, fungi, worms, mollusks, crustaceans, insects and fish, etc., and the light emitted by these animals does not produce heat, so it is also called "cold light".

Among the many light-emitting animals, fireflies are one of them. There are about 1 fireflies

There are 500 kinds of cold light, and the colors of the cold light they emit are yellow-green and orange, and the brightness of the light also varies. The cold light emitted by fireflies not only has a high luminous efficiency, but also the cold light emitted is generally very soft, which is very suitable for human eyes, and the intensity of the light is relatively high. Therefore, biolight is a kind of light that is ideal for human beings.

Scientists have found that the glowing device of the firefly is located in the abdomen. This luminaire is composed of three parts: a light-emitting layer, a transparent layer and a reflective layer. The luminescent layer has thousands of light-emitting cells, and they all contain two substances, luciferin and luciferase.

Under the action of luciferase, luciferin fluoresces when it is oxidized with the participation of intracellular water. The luminescence of fireflies is essentially the process of converting chemical energy into light energy.

Back in the 40s, fluorescent lamps were created based on the study of fireflies, which changed the source of human lighting a lot. In recent years, scientists have isolated pure luciferin from the luminescent device of fireflies, and later isolated luciferase, and then chemically synthesized fluorescein. A biological light source composed of a mixture of luciferin, luciferase, ATP (adenosine triphosphate) and water, which can be used as a flash lamp in mines filled with ** gas.

Since this light has no power source and does not generate a magnetic field, it can be illuminated by a biological light source to remove magnetic mines.

Nowadays, people can use the method of mixing certain chemicals to obtain cold light similar to biological light, which is used as safety lighting.

In life, some teeth with good color and most of them have been whitened with artificial cold light. Why does the color of the teeth immediately increase by 8 vitas after people whiten their teeth with artificial cold light? It turned out that people got inspiration from fireflies.

Fireflies are safe to fly at night. Because behind him there is a luminaire, which is like a lamp that illuminates a large area so that it can see the scene in a distant direction. But how did this luminaire come about?

In order to figure out this problem, in the 40s, scientists finally figured out this problem after repeated studies and countless experiments. This luminaire initiates a nerve impulse that transmits to the light-emitting cells, causing the previously inhibited fluorescein to be uninhibited. Inside the light-emitting cells of fireflies, there is a phosphorus-containing chemical called fluorescein.

Catalyzed by fluorescein, oxidation, the resulting energy is released in the form of light. Since most of the energy produced by the reaction is used to emit light, only 2 10% of the energy is converted to heat. So, when the fireflies stop on our hands, we won't be burned by the light of the fireflies.

That's why scientists call the light emitted by fireflies "cold light."

In this way, scientists imitated the luminous device of fireflies, invented artificial cold light, and made it have a very good effect on people.

Cold light lamp, in the bottom of the mine, high gas concentration, when heated, cold turn off the light safe.

Fluorescent lamps were invented based on fireflies.

People invented fluorescent clothing and cold lights based on fireflies.

Luminous Suit This is a garment developed by scientists to ensure the safety of personnel at night or in a dark environment. It is a luminous suit made according to the revelation of the glow of fireflies, and is made for mountaineering, exploration, and expedition personnel to walk and operate when the light is dim. It emits light like a mirror, emitting light like the glow of a firefly, making it easy to spot even in the dark, and is a way to save people who are lost or have lost contact with the base.

The specific time is not very clear, I know a story of the Jin Dynasty, it is said that Che Yin loves to learn, in order to save the oil money for lighting the lamp, he caught fireflies and put them in a porous sac to replace the oil lamp.

So there were already fireflies at least during the Jin Dynasty.

In the spring from March to April, when there are cucumber seedlings and pumpkin seedlings, it will appear, and it will come to steal food. It's on the back of the leaf during the day, so it's easy to find; At night, they usually fly up to look for their spouse and use a net.

Typically, summer is the peak season for fireflies. It appears in the evening, usually between 8 and 10 o'clock. Of course, it also depends on the morning and evening of the night. After 10 o'clock, the fireflies stop resting.

But fireflies aren't just in the summer. Firefly flashes are also divided into different types, and depending on the species, fireflies appear from March. In the Valley of Fireflies, it can be seen from March to September, but the number will vary.

In addition, some species of fireflies can actually be seen during the day, but they do not shine. There are also fireflies are very seriously affected by the temperature, the temperature fluctuates slightly, or it rains, and the effect is not good. In addition, the effect in the middle of each month is not good, because the moon is too bright, which means that there is strong light in the sky, and fireflies do not like light.
