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 ... >>

Night vision is available to everyone 02.03.2019

Fans of the sci-fi genre will probably remember the 2000 film Pitch Black, starring Vin Diesel. So, the hero of Vin Diesel in this film had night vision, obtained artificially, by special processing of the cornea of ​​​​his eyes. Such a scenario has become practically a reality thanks to the work of a team of scientists from the University of Massachusetts Medical School, who created special eye drops with nanoparticles, the use of which allows experimental rodent animals to see in the near-infrared (NIR) spectrum of light.

Almost all mammals, including humans, are capable of visual perception of light that is only in the visible range. In order to expand the range of light perceived by the eyes, scientists have made nanoparticles consisting of lectin proteins, which have become the active component of eye drops. With these drops, scientists treated the eyes of experimental animals and, as soon as the protein nanoparticles got inside the eye, they “glued” to the photoreceptor cells in the retina. After that, additional proteins turned into a kind of nanoantennas, capable of capturing light in the NIR range, the shortest wavelength of infrared light. By absorbing photons of infrared light, proteins emit photons of green light, which are already captured by normal photoreceptor cells in the eye.

Laboratory tests have fully confirmed that the experimental animals are able to clearly differentiate and respond to images created in the NIR range using a special lamp. At the same time, the introduction of protein nanoparticles did not affect the ability of the eyes to perceive ordinary visible light. Unfortunately, the artificial effect of night vision turned out to be inconsistent, it began to fade to complete disappearance after two weeks after treatment of the eyes with drops with nanoparticles. But most importantly, no adverse side effects have been observed with this treatment.

"The results of our research have greatly expanded the field of practical application of modern nanotechnology" - says Professor Gang Han (Gang Han) - "Such protein nanoantennas will allow scientists to explore many intriguing things, such as the processing of visual signals in the brain of a living being. This, in turn, , can be used to treat diseases and disorders such as color blindness."
