How has air temperature changed over the past 100 years?

Having processed data on air temperature from 5400 weather stations over the past 50 years, meteorologists came to the conclusion that the night air temperature increased by an average of 0,183 ° C every 10 years, and the daytime temperature only by 0,088 ° C.

Who Invented the Drum?

Unlike other musical instruments that were developed by one or more inventors, the drum has been around since prehistoric times. The most ancient peoples, many of which disappeared from the face of the earth a long time ago, used a variety of drums all over the world. Apparently, for the first time, the drum began to be used in order to gather people of a tribe together. It was something like a military signal.

After some time, the drum became an integral part of the music that primitive people used in the fight against "evil spirits". For these people, the sound of the drum had religious significance. And since many rituals were accompanied by dances, the drum provided an excellent accompaniment.

Primitive people used drums made of different materials. Some of these tools were hollow tree trunks with animal skin stretched over them. Bamboo drums were made from long pieces of hollow bamboo stems that were cut open and struck with sticks. Some people struck their own bodies while lying on the ground to make drum-like sounds! The ancient Egyptians made extensive use of drums.

The typical Egyptian drum was small and carried in the hand. The ancient Jews also had drums, which were a kind of tambourine, which was struck with a hand or a stick. The Chinese and Japanese have also used drums since time immemorial. American Indians used drums not only to give signals or musical accompaniment to dances, but even to predict the weather! When rainy weather approached, the skin that covered the drum would stretch.

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 ... >>

Bionic eye saves from blindness 16.01.2019

Scientists from the University of Minnesota have managed to create a prototype of a bionic eye that can give sight to the blind and give superhuman abilities to the sighted.

To design such an optical device for vision, American experts used a specially built 3D printer. First, they printed a base of silver particles inside a hemispherical glass dome. After that, using semiconductor polymer materials, photodiodes were printed on top of the base - devices that convert light into electrical signals. As a result, the experts received a bionic eye that turns light into electricity with an efficiency of 25%.

Researchers are now working on the possibility of transplanting such an eye into a human. To do this, they need to find a suitable soft material to print the hemisphere and add more photoreceptors to the eye to increase the efficiency of the device.
