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 ... >>

Communication with sleepers 01.03.2021

New scientific experiments have demonstrated the ability to ask questions to a person in a lucid dream - and even get the right answers to them.

Some special techniques and mental states allow you to experience lucid dreams, in which a person understands that he is in a dream, and can even control its content. This is a very curious phenomenon that opens up completely unique possibilities for studying sleep. Scientists have been able to demonstrate that a connection can be established between a lucid dreamer and the real world.

Until now, such contacts have remained one-way: having plunged into a lucid dream, people could communicate this with eye movements or perform a prearranged task. But recently a connection has been shown in both directions: people heard the questions of the experimenters and answered them while remaining in a dream.

The work involved several teams of scientists from Europe and the United States, led by Ken Paller (Ken Paller) from the US Northwestern University. They conducted experiments with 35 volunteers who had various lucid dream experiences and another who had narcolepsy and was lucid in his sleep due to a neurological disorder.

Electrodes attached to the head, cheeks and near the eyes made it possible to register the onset of the REM (paradoxical) sleep phase, during which dreams come. Commands were transmitted to the experimental subjects using voice, and eye movements and facial expressions served as feedback, which the sleepers could partially control. For example, they were asked to subtract six from eight - and the subjects answered "two", moving their eyes twice from left to right.

In most cases (approximately 60 per cent), contact could not be made. In 20 percent of the experiments, the answers obtained were incorrect or unclear. However, about 18 percent accounted for certain and reliable communications with sleepers. Moreover, when they woke up, they often remembered the experience. According to the volunteers, the questions sounded in a dream, like a voiceover. However, they did not always reproduce what happened exactly and sometimes they did not name the questions that they were asked.
