Which football player was prevented from making an excellent career by the anticipation of the end of the world?

Argentine goalkeeper Carlos Roa, who played for the Spanish "Mallorca", at the peak of his career, announced his retirement, although he was interested in Chelsea and Manchester United. He explained his decision by the fact that he was waiting for the end of the world, which was to come along with the third millennium. After he returned to football, but played only in teams of the lower divisions.

Random interesting fact from the Great Encyclopedia:

Why is it necessary to take into account its group when transfusing blood?

Doctors have been giving blood transfusions to patients since ancient times. There was a time when they even tried to transfuse blood from an animal to people who suffered from a large blood loss, but it always ended badly. Transfusion of even human blood often led to the death of the patient, so there was a time when laws forbade doctors to perform this procedure.

In the last decade of the 1868th century, the Austrian immunologist Karl Landsteiner (1943-XNUMX) discovered that the blood of different people can be divided into groups and that there are groups that are incompatible with one another. He found that sometimes when one person's whole blood is mixed in a test tube with the blood serum of another person (serum is the liquid part of the blood left after red blood cells and clotting factors have been removed from it), the red blood cells of the whole blood stick together.

If this happens during a transfusion, the clumped red blood cells will clog the blood vessels and stop blood flow, which can lead to the death of the patient. This, however, does not always happen: sometimes the mixing of blood does not lead to the formation of dangerous clusters of cells.

In 1900, Landsteiner published the results of his research, laying the foundation for modern transfusiology, the science of blood transfusion. According to modern concepts, there are 4 main groups of human blood: A, B, AB and 0.

Each person's blood belongs to only one of these groups. If the blood of two people belongs to the same group, it can be transfused from one to another without any risk. Moreover, group 0 can be transfused to people with other groups (A, B, and AB), and groups A and B can be transfused to group AB. But if you transfuse blood of group AB to people with blood types A or B, or transfuse the blood of people with groups A or B to each other, or transfuse a person who has blood type 0, the blood of any other group, then this will lead to aggregation of red blood cells.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

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 ... >>

Global Fresh Water Survey 28.07.2022

The Surface Water and Ocean Topography (SWOT) mission will survey more than 95% of the Earth's lakes, rivers and reservoirs.

Researchers are able to measure water levels in only a few thousand lakes on the planet and have little to no data on the planet's important river systems.

But this problem has been solved thanks to a collaboration between the French space agency Center National d'Etudes Spatial (CNES), involving the Canadian Space Agency and the United Kingdom Space Agency, according to NASA, which is also involved in the collaboration.

The SWOT satellite is scheduled to launch this November from Vandenberg Space Force Base in California. Engineers and technicians are currently finalizing SWOT at Thales Alenia Space in Cannes, France.

This will help to better understand the Earth's water cycle and contribute to better management of water resources, as well as increase knowledge about how climate change affects lakes, rivers and reservoirs.

SWOT can measure more than 95% of the Earth's lakes larger than 6 hectares and rivers larger than 100 meters wide.

Over the ocean, the satellite will be able to "see" elements such as eddies for less than 100 kilometers.
