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 retina based on organic chips
21.11.2023
Scientists from the Bicoca University of Milan have presented a chip made from electronic organic components capable of emulating the functions of the retina. This technology opens up the prospect of using neural implants to treat eye diseases and neurological disorders.
The resulting prototype of an organic chip capable of emulating the functions of the retina marks a significant step towards the creation of advanced neural interfaces. Despite current limitations, the results hold promise for the treatment of eye diseases and various neurological disorders using new technologies.
The presented device is an organic photoelectrochemical transistor consisting of two thin films of a leading polymer deposited on a glass substrate and connected by an electrolyte. One of the films acts as a channel between the electrodes, and the other acts as a gate. Applying voltage to the gate causes ions to migrate from the electrolyte into the channel, changing its conductivity. The uniqueness of the device lies in the integration of light-sensitive molecules, allowing the “collars” to be controlled using light signals, similar to the work of the retina.
This chip successfully simulated two complementary processes in response to light signals, known as short-term and long-term plasticity. Although the prototype is slower than biological neurons and can only respond to biological signals, scientists are already working on the next version, which can create chemical signals to interact with biological systems.
The project not only anticipates the development of all-organic neural implants, but also opens a new era of interaction between traditional electronics and biological systems.
