Focus Description:

Flip through a small album. All sheets are clean. If you flip through its pages again, different pictures will appear in the album. To show such a wonderful album, you need to work with the props in advance.

Focus secret:

The secret is in the accordion. The album is made from a strip of thick paper (such as whatman paper) folded into an "accordion". The outer pages can be colored like a cover. On one side of the sheet there are pictures, on the other - they are not. If you flip through such an album on one side - blank pages. Imperceptibly turn it over and flip it on the other side - now you will see pictures on the pages.

The main thing is to learn how to turn the album over imperceptibly. It is possible at this time to divert the attention of the audience with some words.

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 ... >>

Why does a person continue to eat, although already full 17.06.2019

The amount of food we eat is critical to our weight. However, despite the feeling of satiety, it is sometimes difficult to stop eating. This is especially true for high-calorie snacks. Scientists from the University of North Carolina studied the reasons for this habit.

An important role in the fact that we cannot resist our desire to consume high-calorie foods is played by the protein nociceptin. In the mammalian nervous system, it acts as a signaling molecule. In laboratory studies in mice, compounds that blocked the activity of the protein influenced the desire to consume high-calorie foods. "The scientists found that inhibition of neurons that produce this protein reduced overeating in mice.

The researchers also found that when the mice were given the opportunity to eat a high-calorie meal, a cycle was triggered in their brain that affected the central part of the amygdala, which is responsible for processing emotions, among other things.

Thus, eating in spite of the feeling of fullness is explained by the complex interaction between proteins and the control of emotions in the brain.
