 Random interesting fact from the Great Encyclopedia:

What birds are seen in prostitution?

Adélie penguins build nests for laying eggs from pebbles. When nearby couples are distracted, these penguins don't hesitate to steal their stones. And some females are engaged in prostitution for the sake of stones, although they have a permanent partner. They find solitary males who also make nests in the hope of starting a family, allow them to mate with them, and then carry one or more stones to their nest.

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 ... >>

Film media 15.04.2017

Scientists from the Department of Electrical Engineering, as well as Computer Engineering from the Faculty of Engineering NUS - National University of Singapore, have invented the latest multilayer ultrathin film, which can be used as a carrier, storage, processing of information on new generation magnetic media.

This film is an important step in creating storage devices that run faster and use less power. It is based on the discovery in 2009 of a skyrmion, which is a magnetic vortex formation, a few nanometers in size. They were studied as potential carriers of information of the next generation. Skyrmions are found in layered systems of various heavy metals placed under a ferromagnetic material. Due to the interaction of various materials, interfacial symmetry breaking is obtained, which contributes to the stabilization of the skyrmion. Limitations are defined for their use (lack of stability and microscopic size)

The experts were able to create scrymions directly at room temperature (excluding the shifting magnet). In this case, multilayer films of palladium and cobalt were used to stabilize the scrymion. Their discovery will soon make a breakthrough in the field of information storage. Due to thin films, in the future it will be possible to reduce the size and significantly reduce their energy consumption.
