Why are some people left-handed?

Many parents of left-handed children are very worried about this, but are even more surprised when they are told that they should not try to fix it. The authorities say that if there is a strong advantage of the left hand and one easily controls it, then this should not be hindered.

About 4% of the population are left-handed. If you look into history, it turns out that many geniuses were left-handed, for example, the greatest sculptors of all time - Leonardo da Vinci and Michelangelo.

Of course, we live in a right-handed society, and most of the items we use are made for such people. Doorknobs, locks, screwdrivers, cars, musical instruments and even buttons on clothes. Everything leads to the appearance of certain adaptations for left-handers, but often they do well without it.

There is no generally accepted explanation for why most people are right-handed, and only a small number are left-handed. One theory is that our body is asymmetrical, that is, the right half does not exactly repeat the left. The right side of the face is slightly different from the left, one leg is longer than the other, the feet are slightly different in size. And this asymmetry is observed throughout our body.

The right and left hemispheres of our brain also function differently, and it is assumed that the left dominates over the right.

Nerves connect each hemisphere to the opposite side of the body: the right hemisphere to the left and vice versa.

And since the left side of the brain predominates, then the right side of the body is more perfect, better adapted. We read, write, speak and work with the left hemisphere of the brain. This explains the fact that most of us are right-handed. In left-handers, a rearrangement occurs, that is, the right side of the brain prevails over the left, and therefore, such people have a better command of the left side of the body.

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 ... >>

Gadget for the treatment of seasickness with electrotherapy 16.09.2015

Researchers at Imperial College London have developed a method to prevent seasickness through electrical stimulation. They expect to create a portable device with electrodes connected to the head and put it into mass production.

Transcutaneous electrical nerve stimulation (TENS) has long been successfully used to relieve acute and chronic pain of various origins, including headache. Electrical impulses from electrodes located on the skin above the pain focus stimulate the nerves to block pain signals in the direction of the brain, and the pain is not perceived.

The authors proposed to stimulate the left parietal lobe of the brain with electrical discharges in order to influence the vestibular apparatus of a person and thus eliminate the occurrence of nausea associated with seasickness.

The method was tested by 20 volunteers, including 10 men and 10 women. Electrodes were fixed on their heads for about 10 minutes to influence the current. The subjects were then seated in a motorized chair that rotated and tilted, simulating the conditions under which seasickness occurs in humans while traveling in ships and cars. The scientists recorded how long it took before the participants reported that they were feeling unwell, and then that the nausea had subsided. After the volunteers recovered from the first test session, the second session was carried out in the same way.

The authors noted that the current parameters and duration of exposure selected by them are safe for human health. According to the results of the experience, patients who underwent electrotherapy were less prone to seasickness and recovered from it faster than those who did not receive such treatment.

The researchers expect that in five to XNUMX years the technology will find its way into over-the-counter devices like those already available that use TENS to relieve chronic pain as well as pregnancy pain. Perhaps they will represent a cap with electrodes that can connect to a smartphone and use its processor and battery.
