How do bats see?

Bats are very unusual creatures. And the unusual way they move is just one of the amazing things about them.

Bats are not birds, they are mammals. Their cubs are born by live birth and feed on the milk of their mother. They are the only mammals that fly.

For a long time, scientists could not understand how bats navigate in space in pitch darkness without bumping into trees and other obstacles. They conducted special experiments. In a large room, they hung ropes fairly close together from the ceiling. Then closed the eyes of several experimental animals and released them into the room.

The bats were still flying at high speed without bumping into obstacles. This proved that they are not guided by sight during their flights. Then the scientists closed their ears and mouths and let them out again in the room. But this time they flew with difficulty, constantly bumping into the ropes.

Thus was discovered a means by which mice are guided during flights. While flying, they constantly make sounds so high that the human ear cannot catch them. These high-frequency sound waves, hitting obstacles in the path of the animal, are reflected and perceived by the ears of bats.

Their wings automatically respond to these signals, and the animal can change its course, flying around obstacles!

How was Emperor Paul I going to help Napoleon in the war against Great Britain?

Having established friendly relations with Napoleon Bonaparte, the first consul of France, at the end of 1800, the Russian Emperor Paul I decided to help him in the fight against England.

On January 12, 1801, the emperor sent several rescripts to the ataman of the Don Army, General Orlov 1st. They ordered to immediately raise the Cossack regiments and move them to Orenburg, and from there by direct route to India, in order to "hit the enemy in his heart."

On the same days, the Cossack ataman Matvey Ivanovich Platov, who had been planted by Paul for some unknown reason in the Peter and Paul Fortress for six months, was suddenly taken out of his casemate and taken directly to the royal office. There he was asked without any preamble if he knew the way to India. Understanding nothing, but guessing that in the event of a negative answer, he would be taken back to the fortress, Platov replied that he knew. He was immediately appointed head of one of the echelons of troops sent to India. On February 27, 1801, Cossack regiments rose from the Don and went east.

In total, 22,5 thousand people followed in four echelons. They did not have long to go: on the night of March 11-12, in the Mikhailovsky Castle, the conspirators, incited by the British, killed Paul I.

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 ... >>

Electric car as a backup power source in the house 09.03.2022

American General Motors Co. launches a pilot project where the company's electric vehicles can be used as backup power sources in customers' homes.

The project will be implemented jointly with Pacific Gas and Electric Company, the key operating company of the California generating PG&E Corporation.

The first tests are planned to be carried out closer to the summer, larger ones - by the end of this year. It is assumed that electricity from a charged electric car will be transferred to the house automatically using special software and data transfer protocols.

PG&E CEO Patty Poppy said that the ability to use electric vehicles as a backup power source will be a significant advantage, as well as help in the fight against climate change.

A similar project is currently underway by Ford Motor and Sunrun Inc. The latter is one of the leaders in the US solar energy market.

The launch of the experiment is scheduled for this spring.
