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 ... >>

Chip that determines the amount of alcohol in the blood 11.04.2021

Knowing the exact amount of alcohol in the body is useful not only for drivers, but also for those who take drugs that are incompatible with alcohol, or who are struggling with addiction to the green snake. Previously developed tools are not always practical, despite the reliability of the indicators. However, a recent study will address all possible inconveniences.

Scientists from the US have created a chip that allows you to determine the amount of alcohol in the blood. Its peculiarity is that it is implanted under the skin. The development does not exceed 1 cubic millimeter in size.

As a rule, the amount of alcohol in the blood is determined using a blood test or exhalation of air into a special device. Both methods are not always practical, as there are times when you need to monitor the level of alcohol constantly. For example, such cases include the treatment of people with alcohol dependence.

Thanks to the development of scientists, it is possible to track the amount of alcohol and fluctuations in its level in the blood constantly and without additional accessories. The chip itself does not contain a rechargeable battery. It is powered by external energy sources such as a smart bracelet or watch.

The principle of operation of the device is to determine the amount of alcohol as soon as it enters the bloodstream. When this happens, the electrochemical parameters of the sensor change, and it notifies about this using a radio signal.

The developed drug will help to fight alcoholism more effectively and take certain medications without fear for health. The number of accidents due to alcohol consumption will also decrease.
