What holiday decorations were originally sweet and edible?

Since ancient times, there has been a tradition to shower the participants of balls, carnivals, weddings with sweets. They got the name "confetti" from the Italian word for "candied" (hence the candy also got its name). Later, they came up with the idea of ​​replacing sweets with small pieces of paper, but the word for them - confetti - remained the same.

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 ... >>

Controlling things with the power of thought 09.06.2022

Now telekinesis, the movement of objects with the power of thought at a distance, is in the minds of many something from the realm of science fiction. But Chinese scientists are actively working to make this phenomenon a reality.

Scientists at the China Air Force University of Engineering have taken the first step towards remote control of metamaterials using human brainwaves in a new study.

Metamaterials are man-made materials that have unusual physical properties, including electromagnetic properties, that do not occur naturally. The two-dimensional analog of metamaterials are metasurfaces, which have unprecedented freedom in controlling electromagnetic waves. According to scientists, it is possible to create programmable metasurfaces with different functions that can be controlled remotely using the human mind.

It is well known that the human brain creates brain waves in the process of thinking. Scientists have suggested that with the help of brain waves, which can be used as signals, you can control and control your metasurface mind.

During the study, Chinese scientists managed to achieve remote control of the metasurface through the transmission of human brain waves to a special receiver. Scientists wanted to make sure that a person can control the electromagnetic reaction of a programmable metasurface. And they were able to achieve this by demonstrating user control of the metasurface electromagnetic wave dispersion mode.

The results of the experiment showed that with the help of brain waves, a person more effectively controlled the functions of the metasurface at a distance than with the help of devices manually. Now, scientists plan to continue to conduct similar experiments in order to improve the quality of control over the metasurface with the help of the human mind.

Scientists believe that mind control at a distance can really be applied to various metasurfaces, including this method of control and management can be applied to monitor the state of human health, to transmit data in 5G and 6G communication generations and other areas.
