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 thoughts 21.08.2022

You can get tired not only from physical work, but also from thoughts - not from some specific heavy thoughts, but from mental stress.

Many people know that in the evening you think worse than in the morning, that in the evening it can be difficult to remember what you ate for breakfast today, not to mention planning the next day. Someone explains this by saying that the brain expends energy - and it really expends energy - and more energy is spent on complex mental tasks than on simple ones.

Cognitive fatigue is a sign of brain exhaustion, and you can get rid of it by supplying the brain with food, such as glucose. But the energy hypothesis, despite its obviousness, was not experimentally confirmed. The brain consumes energy, but mental fatigue does not arise from this.

Researchers from the Brain Institute in Paris, the Pitié-Salpêtrière Hospital and the Sorbonne University write in Current Biology that the neurotransmitter glutamate may be the cause. Glutamate (glutamic acid) is used by a variety of neural circuits, including those involved in memory and learning. At the same time, an excess of glutamate harms neurons - because of it, they are overexcited and die. In their experiments, the researchers used magnetic resonance spectroscopy, which uses radio waves and a magnetic field to estimate the amount and distribution of glutamate in the brain.

Thirty-nine experimental volunteers performed various tasks that were supposed to tire their brains. In one case, numbers and letters flashed quickly on the screen in front of a person, and it was necessary to determine just as quickly what color the number or letter was, whether the letter was lowercase or uppercase, etc.

In another case, it was necessary to compare the number that you see right now with the number that you saw three characters ago - that is, here you had to constantly keep in mind the appearing and disappearing numbers. For comparison, another group of volunteers performed the same tasks, but in a simpler version.
