What are spheres?

So scientists call pulses of weak electromagnetic fields, most likely arising from changes in atmospheric pressure. They appear, as a rule, before changes in weather conditions. Perhaps it is to them that especially sensitive people react, who have a deterioration in well-being before a change in the weather. Such people are called weather dependent.

Random interesting fact from the Great Encyclopedia:

Why did the Portuguese prince Henry the Navigator get his nickname?

Henry the Navigator (1394-1460), the fourth son of the Portuguese king João I, became famous as the organizer of sea expeditions to the islands of the central Atlantic Ocean and the western shores of Africa, for which he received his nickname from grateful descendants in the XNUMXth century, although he himself did not swim.

Prince Henry made it his life's goal to survey the coast of Africa in order to open routes for penetration into Asia, bypassing the Arab trade routes. He founded an observatory and a nautical school in the city of Sagris, and contributed to the development of Portuguese shipbuilding. Henry's plans at first did not meet with understanding in Portuguese society.

Opponents of naval expeditions insisted that the prince diverted attention and funds from the main task of the kingdom - the fight against the Moors. However, after the first trading company was founded in Lagos, which managed to profitably sell a large batch of black slaves taken out of Africa on its ships, interest in expeditions increased dramatically.

Largely thanks to the efforts of Prince Henry, the Portuguese were the first to round Cape Bojador (now Bujdur) in 1434 on the coast of West Africa, south of the Canary Islands. In 1441 they reached Cape Blanco (now Nouadhibou), in 1445 they discovered the Green Cape, and in 1462, two years after the death of Prince Henry, they entered the Gulf of Guinea.

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 ... >>

Sex problems on Mars 03.06.2018

The idea of colonizing Mars is not just science fiction; NASA and space agencies around the world are working hard to determine what it will take for humanity to take root on the Red Planet. Humankind faces various problems, such as growing food sources or an unfavorable habitat. But the biggest problem for colonization, scientists see - sex.

In a new research paper, an international team of scientists is studying the problems of humans being born on the surface of Mars.

The first and most obvious obstacle is the low gravity environment, which can pose a serious threat to the processes of conception and pregnancy, which seem so simple on Earth. Scientists are aware of the problems of astronauts who have spent months and in some cases years in space. Lower gravity causes muscles to deteriorate rapidly and can even weaken bone structure. In addition, astronauts sometimes experience vision problems and even changes in the shape of their brains.

The study explores the inherent challenges of sustaining a small colony of settlers on the planet. The concept of "love" should not stand in the way of survival. In addition, some people will never be allowed to have children due to undesirable traits that pose a danger to the colony as a whole.

But the most frightening thing is that in the course of colonization, a new kind of person may appear that can thrive on Mars, but cannot live on Earth.
