How do we grow?

All living things grow and develop: both in shape, size, how it is made, and in its purpose and capabilities.

The most important forces that cause growth are contained within a living being from the moment of its inception. These forces are called heredity. Animals, including humans, have stages of growth and development. These include: the embryonic and uterine state, infancy, childhood, youth, maturity and old age.

In some creatures, one can hardly speak of the period of infancy. For example, there are birds that can fly as soon as they hatch. A guinea pig is able to take care of itself three days after birth. But a person is not an adult until about 20 years old.

At birth, a baby already has all the nerve cells that a person is supposed to have: cells of the brain and spinal cord and those that penetrate into all parts of his body. The development of connections between these nerve cells helps him learn to control his movements, learn about the world and behave in a way that is accepted in his society.

So, all people are very similar in their development. But there are also important differences. Both boys and girls develop, of course, along the same general path, but still each of them has his own path and his own speed of development.

In the first weeks of life, a person grows faster than ever. Even at the end of the first year of life, it develops more slowly. It grows at a moderate rate throughout childhood. Then again comes a period of intensive growth. For girls, this usually occurs at 11-13, for boys - at 12-14 years. They grow faster for a while until they reach their peak speed. Then growth slows down again until it stops altogether. This suggests that the person has reached the maximum size.

Growth in height and weight gain often occur alternately in a person. First, for some time, it develops in height, then in width. For many people, somewhere between the ages of 11 and 12, the so-called "chubby" period begins. But in the following years, they begin to catch up in growth, and fatness passes.

How did Saudi Arabia disprove the idea of the devilish origin of the phone?

When the first telephone line in the country was laid in the palace of the king of Saudi Arabia, religious figures made a fuss: this diabolical invention of the infidels has no place on the land of Muslims!

However, King ibn Saud reasoned as follows: "If the phone is really a creation of Satan, then the holy words of the Koran will not be able to pass through the telephone wire. Let's take two mullahs, put them at different devices and ask them to read verses from the Koran in turn. If one can hear the other - so it's all right."

The result of the experiment removed all concerns, and since then the phone is allowed in Saudi Arabia.

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 ... >>

Method of non-surgical treatment of neurological diseases 15.05.2023

American scientists have developed a non-invasive way to remove problematic neural circuits, allowing you to treat serious neurological diseases without the usual brain surgery.

Researchers at the University of Virginia School of Medicine, along with colleagues at Stanford University, have for the first time used not a scalpel or probe to penetrate the brain, but low-intensity ultrasound waves combined with neurotoxin-carrying microbubbles. This allowed them to target the problem cells and kill them, while preserving the surrounding healthy cells and the overall architecture of neural connections, while currently available surgical approaches damage all cells in the treated area of the brain.

Scientists believe that their discovery could revolutionize the treatment of the most complex neurological diseases, such as epilepsy, movement disorders and many others.

This new surgical strategy could replace existing neurosurgical procedures, as well as be used to treat neurological disorders that are not yet treatable. brain. - This unique approach removes diseased brain cells, preserves neighboring healthy cells, without even breaking the scalp. The authors have already demonstrated the effectiveness of a new technique called PING in the treatment of epilepsy in two laboratory models.

It is known that about a third of patients with epilepsy do not respond to anticonvulsants and dangerous surgery is required to eliminate seizures. Experts are confident that their method will help these people. We hope that the PING strategy will become a key element in the next generation of highly precise, non-invasive neurosurgical approaches to the treatment of major neurological disorders.
