In total, the World flew in space for about 3,7 billion km, which is comparable to the distance from the Earth to Uranus. The cost of maintaining the station amounted to $4,2 billion.

Thus, each second of the flight, or 8 km of the path that the station covered during this time, cost about $ 9. The amount is quite comparable to the cost of a taxi in Florida - $ 1,6 per mile. Moscow taxi drivers ask for 8-60 rubles for 70 km.

The purring of an ordinary domestic cat occurs at a frequency between 22 and 44 hertz. Scientists at the Institute of Fauna Research in North Carolina came to the conclusion that vibrations at this frequency accelerate the process of cell regeneration. So when injured cats purr, they are just self-medicating. It is noteworthy that this frequency also improves the condition of human bone tissue. Therefore, close communication with domestic cats can actually improve human health. (top.rbc.ru)

Mobile phones are not only one of the most convenient means of communication for a modern person, but also contribute to the development of intelligence. Hong Kong scientists came to such an unexpected conclusion.

The researchers conducted a series of tests among two groups of people. The first group constantly used mobile phones, and in the second group, the subjects knew about mobile phones only by hearsay. They were offered to pass the same test, which shows the level of intelligence. And it turned out that the group of mobile phone users is more intellectually developed. They have clearer logical thinking, and they solved problems at least twice as fast.

Scientists believe that the cause of this phenomenon is the electromagnetic waves emitted by a mobile phone. Somehow they affect certain parts of the brain, provoking intellectual activity. Only in this way can the researchers explain why the test results turned out to be so different. Professor Lee, who conducted this experiment, believes that during a conversation on a mobile phone, a certain electromagnetic heating occurs in the ear area, which causes changes in the brain tissue.

Domestic cats are not very sensitive to the poison of vipers and catch them without fear for their own lives. Some cats dare to fight even with a cobra. And not without success. A pig does not need immunity or needles. Its safety is guaranteed by a thick layer of fat, in which the poison settles.

On the body one or more humps. Rounded curly tail. If you believe this description, then Nessie is very similar to a plesiosaur, a fossil fish lizard from the Mesozoic era.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>
