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 ... >>
Random news from the Archive Anger of hungry people
20.01.2016
Anger and other negative emotions are the reaction of the human body to the feeling of hunger. These unpleasant sensations arise due to a certain work of nerve cells.
The main task of this mechanism is to start the behavior aimed at finding and eating food in order to eliminate the energy deficit in the body. This conclusion was made by scientists from the Howard Hughes Medical Institute (USA), who studied the phenomenon of anger in hungry people.
A team of physiologists conducted experiments on mice. Rodents were periodically left hungry and, thanks to devices implanted in their brains, they monitored the reaction of hypothalamic neurons to this state.
It turned out that the neurons were invariably activated in hungry mice. At the same time, their activity decreased not when the mice began to eat, but earlier, when they were only shown food. The researchers tried showing objects that looked like food. Interestingly, in such experiments, the activity of neurons decreased and resumed at the moment the rodents detected the forgery. The speed of these nerve cells allowed doctors to conclude that neurons send exactly unpleasant signals to the brain, prompting a hungry creature to take the necessary actions.
The researchers explain the emergence of this phenomenon as follows: satisfaction with eating and the discomfort and anger that accompany the feeling of hunger are the legacy of distant ancestors. It was these sensations that ensured the survival of animals by inducing them to hunt and eat regularly. In today's society, the ancient mechanism is no longer needed and even harms people trying to control weight, leading to the development of obesity, heart problems and diabetes in a society for which food has ceased to be a means of survival.
Previously, another team of American researchers learned how to control the neural network responsible for the feeling of satiety in laboratory mice. By activating certain nerve cells, they ensured that even hungry rodents would not take the food offered to them. Scientists hope that over time they will be able to "turn off" the feeling of hunger in people.
