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 Creation of new plants without DNA insertion 29.12.2015 The brilliant idea of ​​gene transplantation has run into so much resistance from society that breeders are forced to look for workarounds to quickly create plants with improved properties. One of them is genome editing without the use of foreign DNA. Researchers from the South Korean Institute of Basic Science, led by Jin-Soo Kim, tested this method on lettuce, tobacco, and rice cells. Edited with CRISPR/Cas9 molecular scissors. Such a design cuts the plant's DNA in a precisely chosen place, and then the cell closes the damage on its own, thus withdrawing the marked gene from circulation. That is, nothing is inserted into the genome - they only turn off the plant's own gene. According to the authors of the work, the procedure practically does not differ from the usual mutagenesis that occurs in nature, except that it is not a random gene that is damaged, but a pre-selected one. Experiments with edited cells showed that the operation was successful: there was no mosaic of genes in the samples of proliferating cells. From the seeds obtained, it was possible to grow edited plants in almost half of the cases and in the second generation. Since they do not contain foreign DNA, they are not subject to EU restrictions. Moreover, the technique is relatively simple, and it can be used in small seed farms, which removes a serious problem - dependence on a monopoly producer of transgenic seeds. True, genome editing may not be so harmless and without any foreign DNA. For example, in potatoes, poisonous berries accompany completely edible tubers. They have one genome, it's all about the regulation of gene activity. And if you inaccurately edit this very regulator, then ...
