In 1906, the First State Duma became the parliament proper, the legislative body elected by the people.

How did a Hungarian chemist catch canteen workers reusing food leftovers?

The Hungarian chemist György de Hevesy, a future Nobel laureate, worked in Manchester in 1911 on the use of isotope tracers. Not having much money, Hevesy lived in a hostel and ate in the dining room. Suspecting the workers of using half-eaten leftovers to prepare new dishes, the scientist added a small amount of radioactive materials to his plate. A few days later, he took a sample of a similar dish and confirmed his fears by detecting the radioactivity of food using an electroscope.

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 ... >>

Peaceful creatures turn into predators 16.01.2017

Last fall, the American firm Northrop Grumman announced plans to develop, together with the US Air Force Research Laboratory, a small laser that would be mounted on fighter jets and serve as a "defensive" weapon, i.e. hit attacking missiles, drones and enemy aircraft. Thanks to active focusing, the future system will be able to perform various tasks as needed, including identifying targets and changing the focus of the laser to maintain maximum efficiency when the air is disturbed along the path of the beam.

Recently, scientists at Yale University unexpectedly discovered another possible use for such a laser, although their research has not (yet) been in the field of defense. They studied the predatory instincts of animals using optogenetics, stimulating the activity of neurons through targeted irradiation of cells. So far, this technique has been used, for example, to deliver drugs to deep brain tissues, possibly treat acquired blindness, and to control pain.

In a new experiment, scientists stimulated neurons in the amygdala of a mouse's brain with a laser and found that one of the nerve groups triggered a predatory instinct in the animal, while another turned on the jaw muscles, causing the mice to bite anything and everyone in their path. When the laser was turned on, the mice jumped on the object, grabbed it with their jaws and began to bite intensely as if it were their victim. Moreover, the hungrier the mice were, the more aggressive their behavior was, and they bit absolutely everything they came across - bottle caps, sticks, toys and live insects. However, they did not attack their fellow caged mice, which is quite valuable if this technology is used for the soldiers of the future.
