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 Dirty air makes people stupid
01.09.2018
According to a new study by scientists in the US and China, prolonged exposure to polluted air affects human cognitive performance.
To investigate the link between air pollution and cognition, the researchers turned to the results of the China Family Panel Studies, an annual test of Chinese citizens that includes verbal and mathematical tests of cognitive performance. The scientists especially focused on the results obtained from 2010 to 2014 in 162 randomly selected Chinese regions. In total, about 20 people participated in the study in this way.
They then used official air pollution data to calculate how much a person was exposed to it between inspections. So scientists were able to determine how dirty air affects the human intellect.
The results were rather unpleasant, especially in the case of older people. “We already understand that air pollution can reduce the level of education for a whole year, which is a huge figure,” says Qi Chen, one of the researchers. “But we also found that this effect is even more pronounced in older men over 64 and with low level of education. If you calculate the cognitive losses for them, then there the number goes on for several years. "
Researchers do not yet know why pollution has such an effect. But they are sure that it causes mental decline - that is, it is not just a correlation between the two indicators. Perhaps the whole point is that such air adversely affects the white matter in the brain.
