Why did the code words of the operation appear in crossword puzzles on the eve of the Normandy landings?

The operation to land the allied troops in Normandy in June 1944 was being prepared in conditions of strict secrecy. Shortly before her, British intelligence was greatly puzzled by crossword puzzles in the Telegraph newspaper, in which the code words of the operation appeared every now and then. Among them were Utah and Omaha - the code names for the beaches where the landing was planned, as well as Mulberry, Neptune and even Overlord - the code name for the entire operation. The crossword editor during interrogation stated that these were ordinary words, and their choice was not dictated by any special circumstances. Later it turned out that the editor was part-time teacher and often asked his students what words they would like to include in the crossword puzzle, and the boys heard these five words in the conversations of American soldiers stationed near the school.

Can butterflies remember events that happened to them in the caterpillar stage?

For a long time, scientists did not know whether insects with full transformation could retain any memories from past stages. In 2008, scientists at Georgetown University conducted an experiment with hawk moths - they hit the caterpillars with an electric discharge when a certain smell appeared. When the caterpillars became butterflies, they avoided this smell. A temporal distinction was also established - if the caterpillars were trained at the age of up to three weeks, in the butterfly stage they did not shun the smell. The researchers concluded that butterflies retain memory only if the caterpillar's nervous system reaches a certain maturity.

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 ... >>

Artificial photosynthesis system 28.03.2020

Photosynthesis is a sunlight-induced chemical reaction that green plants and algae use to convert carbon dioxide (CO2) into cellular fuel. Scientists around the world are looking to use it to create fuels that can power our homes and vehicles. The team of Heinz Frei at Lawrence Berkeley National Laboratory has managed to create a technology that comes very close to solving this problem.

The new artificial photosynthesis system includes a "solar fuel stove" that contains billions of nanosized tubes sandwiched between caps made of thin, slightly flexible silicate, with tube holes pierced through the caps. Each tiny (about 0,5 micrometer wide) hollow tube inside the tile is made up of three layers: an inner layer of cobalt oxide, a middle layer of silicon dioxide, and an outer layer of titanium dioxide. In the inner layer of the tube, sunlight energy delivered to cobalt oxide breaks down water molecules (in the form of moist air that passes through the interior of each tube) to form free protons and oxygen. Protons easily flow through the outer layer and combine with carbon dioxide, resulting in the formation of fuel - carbon monoxide.

Fuel is collected in the space between the tubes and can be easily drained into a separate container. In this case, the middle layer of the pipe wall retains oxygen formed as a result of the oxidation of water in the inside of the pipe, and blocks the penetration of carbon dioxide and the resulting fuel molecules from the outside to the inside, thereby separating two very incompatible chemical reaction zones.

The design of the system mimics real living photosynthetic cells that share oxidation and reduction reactions with organic membrane compartments within the chloroplast.

Currently, using the new system, scientists receive fuel in the form of carbon monoxide and are working on obtaining methanol.
