Focus Description:

Having called the viewer, extend your hand to him, wanting to say hello. When your palms come together, wince in pain. Those present will hear a loud crunch of bones. Grasp the “injured” hand, shaking your finger at the spectator who squeezed your fingers too tightly.

Focus secret:

In fact, the crunch did not come from the bones broken during the handshake. You just first took a plastic cup (preferably transparent) and put it under your arm, bottom up. And when your palms came together to shake hands, you pressed the elbow of the hand holding the cup tightly to your side. This caused the glass to break, making that same terrible crunch. Everything else is just a game.

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 ... >>

Tired of your own thoughts 11.10.2023

It is known that mental work can cause fatigue no less than physical work. Scientists from the Pitié-Salpêtrière University Hospital in Paris conducted research and, according to them, identified the chemical causes of fatigue associated with mental processes. Experts have suggested that cognitive work leads to chemical changes in the brain.

Scientists believe that mental fatigue is caused by the accumulation of a certain chemical in the brain responsible for regulation. This substance, known as glutamate, is present in the central nervous system of mammals and plays a key role in a variety of processes such as learning, memory and the sleep cycle.

To test their hypothesis, the researchers conducted an experiment. Participants were asked to perform various mental tasks for 6 hours. Half were given simple tasks, and the other half were given more complex ones. Scientists found signs of fatigue only in the group that did more complex tasks.

The researchers used magnetic resonance spectroscopy to measure biochemical changes in the brain. The results showed a measurable difference in glutamate levels between the group that did the difficult tasks and the group that did the easier ones. According to scientists, increased glutamate levels cause the body to use more resources to maintain brain activity, which in turn leads to increased fatigue.

Thus, it can be said that the more we engage in thinking about complex problems, the more we become tired of our own thoughts.
