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 ... >>

Robot lizard travels through the sand 05.04.2013

A robot lizard with C-shaped legs, created by a group of American scientists, can become a champion in moving on sand, gravel and other loose surfaces. In addition, it will help scientists in creating a full-fledged mathematical theory that describes movement on surfaces with the properties of both a liquid and a solid body.

In an article published in the journal Science, Daniel Goldman of the Georgia Institute of Technology and his colleagues note that movement on a loose surface is mathematically more complex than movement in a liquid. Scientists have developed the basic provisions of "terradynamics" and tested them in the experiment: using a 3D printer, they printed various forms of "legs" for an experimental robot weighing about 150 g.

“While the legs are convex, the robot has a large step with little body resistance, and therefore it can run fast. When the shape of the robot’s limbs is flat or concave, the performance drops,” Goldman cites the article. According to him, during the experiments it became clear that the laws of this movement are common to all loose media, including those consisting of poppy seeds, glass beads or natural sand.

Scientists believe that the advantageous form of limbs they have found for a robot can later be used to create a promising apparatus for search and rescue operations, as well as in the study of Mars.
