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 ... >>

Sunburn without UV 25.06.2017

A tan appears because ultraviolet stimulates the synthesis of melanin, a dark-colored pigment that must absorb ultraviolet radiation, preventing it from penetrating deeper and harming the deeper layers of the skin. But the skin will still receive some harm: the DNA in the cells will be damaged, and it remains only to hope for molecular repair enzymes that will correct these damages and prevent cell death or, even worse, the transformation of cells into cancerous ones.

However, life is simply not sweet for many without a tan, and they still go out into the sun again and again or go to the solarium. Is it possible to get tanned skin without being exposed to dangerous ultraviolet radiation? Researchers at the Massachusetts General Hospital and the Dana and Farber Cancer Institute say it is possible.

A few years ago, experts experimented with mice that were unable to synthesize melanin - such animals had a mutation in the genome that turned off pigment synthesis. But at the same time, it was found that a substance called forskolin could trigger the synthesis of melanin, bypassing the mutation, so that there was enough melanin to protect mice from the unpleasant effects of ultraviolet radiation.

However, at the same time it turned out that forskolin is useless for humans: compared to mice, our skin is thicker, and the substance simply does not penetrate to a sufficient depth. However, the researchers were able to find another compound - more specifically, a whole class of compounds that are similar in action to forskolin and that are effective on human skin. Cells have special enzymes, abbreviated as SIK, on which the activity of genes that control melanin synthesis depends. Scientists have studied molecules that inhibit the activity of SIK proteins, thereby activating pigment synthesis. The specific molecular mechanism is different than with forskolin, but the end result is the same: a UV-free tan.

Before any drugs with "tanning molecules" appear on the market, you need to make sure that they will not have any oncological and generally any harmful effects.
