Focus Description:

Have you ever tried multiplication with your fingers? It's easy.

On the fingers, you can multiply any number by 9.

Focus secret:

Let's say we want to multiply 9 by 6. We bend a finger with a number equal to the number by which we will multiply the nine. In our example, you need to bend the finger with number 6. The number of fingers to the left of the bent finger shows us the number of tens in the answer, the number of fingers to the right - the number of units. On the left, we have 5 fingers not bent, on the right - 4 fingers.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

The character of a dog does not depend on the breed 16.01.2024

American scientists conducted a study in which the genomes of more than 2 thousand dogs were studied and published the results of their observations. The main conclusion of the study is that breed is not a determining factor in shaping a pet’s character, including its aggressiveness and tendency to obey the owner’s commands.

“Our analysis of the opinions of dog owners and the genomes of their pets showed that belonging to certain breeds explains only 9% of the variability in their behavior. This indicates that the characteristic behavioral traits of dogs were formed randomly during the evolution of their ancestors long before the advent of modern decorative dogs. varieties," the scientists note.

There are more than three hundred officially recognized dog breeds on the planet, but only a small number have been bred to perform specific tasks. Most breeds have appeared in the last three hundred years as ornamental varieties. In determining the breed of a dog, its exterior, appearance and similarity to “reference samples” play a major role. However, for owners, the character and behavior of their pet is more important: aggressiveness towards strangers and devotion to its owner.

A team of geneticists led by Professor Elinora Carlson from the University of Massachusetts at Worcester has found clear evidence that dogs' behavior has little to do with their breed. During the study, the genomes of 2,1 thousand dogs representing 78 breeds were deciphered. In addition, scientists conducted surveys among owners aimed at assessing eight key character traits of dogs.

Geneticists have identified 11 DNA sections that significantly affect the behavior of dogs, but are not associated with specific breeds. Further analysis of genomes and survey results showed that breed did not play a decisive role in shaping the character of both purebreds and mixed breeds of different breeds.

Belonging to a breed explained only about 9% of the behavior of pets. The remaining more than 90% of the variation in their character is due to mutations in genes passed on by individual dogs from their ancestors.

Research shows that dogs' personalities are largely determined by genetic factors unrelated to their breed. These results are important for understanding the behavioral characteristics of dogs and making adjustments to the upbringing and training of animals.
