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 ... >>

A touch from a distance 02.02.2023

Japanese researchers have unveiled a system that allows users to transfer physical sensations and tactile information between devices.

Japanese mobile network operator NTT Docomo, together with Keio University's Embodied Media Project and Nagoya Institute of Technology's Haptics Lab, have developed the Feel Tech platform, which "makes it possible to share experiences that are usually difficult to convey through images, sound, text or words."

The inventors plan to use the technology in a variety of use cases, including healthcare, sports, education, and e-commerce. In particular, they plan to focus on medicine and art.

In addition, they suggest using the platform to "experience the subtle feel of clothing fabric, among other rich experiences that are not possible with other advanced technologies such as 3D or augmented reality."

The system detects a person's sensory state and helps to share tactile sensations by detecting vibrations from a person's touch with a device similar to a piezoelectric sensor and other devices connected to the platform, which then reproduce these vibrations for other users.

The platform is expected to take full advantage of the ultra-low latency that will be offered in future 6G mobile networks to achieve the important synchronization of transmitted tactile and video data, the researchers said.
