What do chameleons do?

They do not change their color at all depending on the surrounding background.

Never changed and never will. Absolute myth. Complete invention. Blatant lie.

The color of a chameleon depends on its emotional state. And if the color suddenly coincides with the surrounding background, then this is exactly a coincidence, nothing more.

A chameleon changes color when it is frightened, or picked up, or if it has defeated another chameleon in a fight. They change color when a member of the opposite sex enters their field of vision, and sometimes due to changes in temperature or lighting.

The skin of a chameleon contains several layers of special cells called chromatophores (from the Greek chroma, "color", and pherein, "to bear"), each with its own color pigments. Changing the ratio between the layers forces the skin to reflect different types of light, making the chameleon a kind of walking color music.

It is even strange how stable the belief is that chameleons change color depending on the environment. This myth first appeared around 240 BC. e. in the writings of Antigonus of Carista, a minor Greek writer of entertaining stories and short biographies. Aristotle - a figure much more influential and also writing a century earlier - even then absolutely correctly associated the change in color of the chameleon with his fear. During the Renaissance, the "surrounding background" theory was once again almost completely abandoned. However, since then, views have changed to diametrically opposed ones, and today this is perhaps the only thing that most people "know" about chameleons.

Chameleons can remain absolutely motionless for hours on end. For this reason, and also because chameleons eat very little, for many centuries it was believed that they feed on air. This, of course, is also not true.

The word chameleon in Greek means "earth lion". The smallest species is Brookesia minima, which is only 25 mm long; the largest, Chamaeleo parsonnii, is 610 mm long. The common chameleon proudly bears the Latin name Chamaeleo chamaeleon, which sounds like the intro of a song.

The chameleon can rotate and focus its eyes completely independently of each other and look in two opposite directions at the same time. However, he is completely deaf. The Bible forbids eating chameleons.

Random interesting fact from the Great Encyclopedia:

What is the upper temperature limit at which microorganisms can live?

The vast majority of microorganisms die when heated to 50-70 degrees Celsius, at higher temperatures only the so-called thermophilic bacteria can live.

Currently known (discovered off the coast of Italy) such bacteria living at 113 degrees today is an absolute record.

However, scientists suggest that the natural limit of life is 130-150 degrees (we are talking about microorganisms in an active state, when bacteria turn into spores, they can withstand even more).

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

CRT monitors will disappear faster than expected 27.08.2005

LCD monitors continue to confidently replace CRT devices in the global market, according to new data from analysts. And this is happening even faster than previously thought.

To date, LCD monitors with diagonals of 15, 17 and 19 inches are the most popular, but larger models are gradually gaining popularity. The global PC LCD market grew 1% qoq to 7 million units in the first quarter of this year, in line with analysts' forecasts, according to a new study by DisplaySearch.

Compared to the same period in 2004, the market grew by 44% in quantitative terms. The rise in price of LCD panels is already beginning to affect the retail price of LCD monitors for the consumer market (this segment is currently on the rise). This usually leads to a slowdown in the growth of the LCD market, especially during periods of seasonal decline in demand.

However, DisplaySearch claims that if all planned LCD panel capacities are put into production, retail price increases will not last long, allowing the market to grow until the end of 2005.
