What primarily determines a person's optimism or pessimism?

An optimistic or pessimistic view of the world of each individual person is programmed genetically. According to research by scientists from the University of Michigan, it is determined by the concentration of neuropeptides Y in the brain: a reduced concentration makes one perceive the environment pessimistically and depressively.

Where do fish live that like to walk on the bottom instead of swimming?

In 2010, new species of anglerfish were found off the coast of Australia. Instead of swimming, these fish prefer to “walk” along the bottom, moving their pectoral fins, which look like animal paws.

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 ... >>

Sleep learning secret revealed 03.11.2022

It is well known that in order to consolidate new information received during the day, you need to "sleep" with it. During the night, all knowledge and impressions will subside and be deposited in memory. A similar process is even reflected in folk proverbs and sayings. However, until now, scientists have remained a mystery of what exactly happens in the brain and how to explain this phenomenon.

To unravel this mystery, researchers at the Pennsylvania State University (USA) conducted a series of experiments in which volunteers slept in the laboratory, and scientists recorded changes in their brain activity. As a result, based on these data, a computer model of the activation of neural networks during sleep was built.

Scientists have found that as the brain goes through slow-wave sleep and rapid eye movement (REM) sleep, which happens about five times a night, one region of the brain, the hippocampus, "teaches" another region of the brain, the neocortex, with the information received during wakefulness. knowledge. Through this process, new ephemeral information is transformed into lasting memories.

The hippocampus is responsible for episodic memory, while the neocortex is responsible for speech, thinking, and other functions of higher nervous activity. During slow wave sleep, the hippocampus communicates with the neocortex and transmits new data to it, and during the REM phase, the neocortex fixes the received information in long-term memory.
