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 ... >>

Mystery of human brain evolution solved 03.09.2012

The rapid increase in the size and cognitive capabilities of the human brain (in the process of evolution) turned out to be due to repeated copying of the same gene.

Everyone knows that the size and cognitive abilities of the brain make a person a special representative of the animal world of our planet. However, so far no one has been able to unravel the riddle of the rapid evolutionary "spurt" that has awarded us with such an amazing mental tool. The results of a study conducted by scientists at the University of Colorado indicate that the key to the puzzle is a large number of copies of the gene encoding the protein domain DUF1220 (from the English. Domain of unknown function - a domain with an unknown function).

This gene has over 270 copies in the human genome. At the same time, the number of copies in the genome of animals is the greater, the greater the degree of its similarity with humans. For example, the DUF1220 domain is encrypted 125 times in the chimpanzee genome, 99 times in the gorilla genome, 30 times in the monkey genome, and only one copy is present in the mouse genome.

The results of the study showed that the more copies of the gene encoding the DUF1220 domain are contained in the genome, the larger the brain size of the organism. This pattern applies not only to different species, but also to individual representatives of the human population. Moreover, the analysis of the genomes of patients with microcephaly - a congenital disease characterized by an abnormally small brain size - and its opposite - macrocephaly - showed that even with pathological abnormalities, the brain size directly depends on the number of copies of the gene encoding the DUF1220 domain.

This discovery provides specialists with a new approach to diagnosing abnormalities associated with brain size. From a broader point of view, it opens up new avenues for studying the human brain and the incredible increase in its size and capacity that has occurred within a very short period from an evolutionary perspective.
