What ruined the culture of the Far North?

First, climate change. When the Eskimos came to the coast of the Arctic Ocean, the climate was 5 ° C warmer than the current one, and the seas were teeming with living creatures. The cold snap has brought this people to the brink of extinction. And later the pale-faced ones came with "firewater" and diseases...

What are lunar craters?

Craters are depressions on the surface of a cosmic body that have rounded outlines. The size of the craters is from 1 meter to 250 kilometers. Large and medium-sized craters on the Moon have been known since the first telescopic observations of this celestial body. They bear the names of famous scientists: Aristotle, Herodotus, Hipparchus, Copernicus, Kepler, etc.

Many large craters are surrounded by gently sloping ridges and have a flat bottom, in the middle of which a central hill rises. Others are in the form of funnels, which are formed during explosions. Numerous small craters cover the entire lunar surface and even the bottom and ramparts of large craters. Craters, even of an unusual shape, were formed when meteorites fell on the surface of the Moon.

Meteorites also owe their origin to the long bright rays that radiate from some large craters (for example, from the craters Tycho, Copernicus, Kepler) over distances of several hundred and even thousands of kilometers. They are chains of small craters covered with fine-grained matter that strongly scatters sunlight.

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 ... >>

Earth's inner core is moving in different directions 07.06.2022

Scientists from the University of Southern California, USA, have found evidence that the Earth's inner core is moving in different directions, which contradicts accepted theories, which suggested that the core constantly rotates at a higher speed than the surface of the planet.

A new study shows that our planet's inner core is changing speed and direction of rotation, as well as moving, as seismic data show.

"We think that the surface of the Earth is shifting relative to its inner core, and also that it rotates more slowly than the planet and can rotate in a different direction," says John Vidale from the University of Southern California.

The Earth's inner core is a hot, dense ball of solid iron about 2600 km in diameter. It cannot be seen directly, so scientists have used seismic data to learn about the speed and direction of its rotation, as well as its movement in the center of the Earth.

In the 90s of the last century, scientists suggested that the inner core of the Earth rotates faster than the planet itself. But a new study shows that the core is spinning more slowly than previously thought. The scientists also found that the nucleus can change the direction of rotation.

According to scientists, the inner core of the Earth does not stand still, but it moves and moves back and forth for a couple of kilometers and this happens every 6 years. Next, scientists plan to study the formation of the core and what other processes occur deep below the surface.

According to existing scientific concepts, the Earth's core consists of two parts: an inner solid core and an outer liquid core. It is believed that the temperature on the surface of the inner core is approximately 6 thousand degrees Celsius, and the density reaches 12,5 tons per cubic meter. So far, scientists have obtained all data on the core only through indirect observations, since it is currently not possible to get to the center of the Earth.
