What direction of the mental number line is innate?

Adults arrange numbers in ascending order on a mental number line in the way they are used to writing: we are from left to right, and, for example, Arabs are from right to left. However, experiments with infants who do not yet know how to write show that the innate idea of the orientation of the number axis is still from left to right. Moreover, the same orientation seems to be characteristic of other animals as well. The little chicks were taught to find food behind a 5-square screen and then presented with two other identical screens. If they had 2 squares, most of the chickens went to the left screen, and if they had 8 - to the right, and the results of the experiment were also confirmed for the numbers 20, 8 and 32.

Which athlete changed his name to Whiskas and why?

When the Australian football team from Geelong faced serious financial problems in 1999, they entered into an unusual advertising contract. Club captain Harry Hawking changed his name to Whiskas, and TV commentators, speaking of the player's actions, unwittingly advertised cat food. After some time, the football player regained his old name.

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 ... >>

Converting hydrogen to metal 06.02.2020

Researchers at the French Commission for Alternative Energy and Atomic Energy (CEA) have been able to shape a hydrogen sample into a form that exhibits the properties of a metal.

The work took many years, as the process itself is incredibly complex. The scientists hermetically sealed the supercooled, solid hydrogen in foil and then subjected it to extremely high pressure using a diamond as an anvil.

In previous experiments, the pressure was limited to 400 gigapascals, but then the researchers came up with the idea to use not a flat, but a toroidal (donut-like) anvil. This allowed it to withstand much higher loads, and at 425 gigapascals, the experiment was finally crowned with success: hydrogen began to show the first metallic properties.

Scientists emphasize that cooling and pressure are two critical factors for changing the state of matter. "As the pressure increases, cooled hydrogen becomes increasingly opaque, and at 425 gigapascals, its surface becomes shiny, highly reflective," they write in their paper.

Hydrogen is one of the most common chemical elements on Earth. It is easy to obtain from water, and therefore the source of potential raw materials for the production of metallic hydrogen or, say, hydrogen fuel is practically inexhaustible. In addition, for its extraction it is not necessary to harm the environment and destroy the ecosystem, as is the case with fossil fuels. In addition, the researchers also have a purely scientific experiment: until now, scientists do not know a place in the Universe where huge pressure is combined with extremely low temperatures, which means that there is either no hydrogen in the metallic form in the world at all, or its source is still hidden from us.

Metallic hydrogen is a potential fuel that will not only radically change the earth's energy, but will also give us a chance to carry out space flights, which so far can only be dreamed of. Now scientists are aiming to get enough metallic hydrogen to carry out some of the necessary tests and experiments. The ultimate goal is, of course, to develop a cheap and relatively simple way to produce this amazing substance on an industrial scale.
