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 ... >>

Catch the neutrino 05.07.2011

Possible messages from extraterrestrial civilizations are usually searched for in the radio range, and lately in the optical range (hoping that we can be signaled by powerful lasers). However, American astrophysicists John Learn and Anthony Zee believe that it is necessary to listen to neutrino fluxes.

Unlike electromagnetic waves, these particles are hardly absorbed or scattered by interstellar gas and dust. True, it is very difficult to catch them. On Earth, physicists use the so-called neutrino telescopes for this - huge reservoirs of water or other liquid, or an array of ice. A small part of the neutrino, flying through liquid or ice, nevertheless reacts with matter and gives itself away.

But it is possible that higher civilizations already possess much more advanced means of capturing and generating or modulating neutrino fluxes. Perhaps, Lernd and Zee say, it makes sense to look at the data already available on neutrino fluxes: could there be encrypted messages from aliens among them?

By the way, the idea is not so new: the plot of Stanislav Lem's science fiction novel "The Voice of the Lord" (1968) is based precisely on attempts to decipher the message of another civilization that came in a stream of neutrinos.
