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 Artificial wood from the laboratory
19.12.2023
Now not only meat, but also trees can be grown in laboratory conditions. Scientists from the Massachusetts Institute of Technology have developed artificial wood without harming any living trees.
This important scientific advance not only provides new opportunities in forestry, but also raises questions regarding the environmental impacts and potential challenges associated with the use of artificial wood. The prospect of reduced deforestation raises important questions about sustainability and the responsible use of natural resources.
The researchers extracted cells from the leaves of the major plant, a colorful subshrub often used for decoration. The resulting cells were placed in the conditions necessary for their reproduction - a liquid and nutrient medium.
The cells were then transferred to a gel matrix (a porous material made from gel tubes) where they continued to grow. To convert these cells into lignin, which gives wood rigidity, scientists added auxin and cytokinins - special plant hormones.
The experiment was completed successfully, the wood successfully grew in the matrix. This opens up the prospect of being able to grow material similar to that currently mined through mass logging. Moreover, the new method requires less equipment for transporting and subsequent processing of wood.
If this invention becomes widespread, it could lead to a reduction in logging worldwide. However, there is a possibility that this will not have a positive impact on the climate crisis.
