Why do football fans shout: Shai-boo! Shai-boo!?

Cry of the fans: "Shai-boo! Shai-boo!" can be heard at both hockey and football matches. This happened thanks to the famous hockey player Boris Mayorov, who loved to play football and even took part in the matches of the USSR Major League for Spartak. When the ball hit Mayorov on the football field, the fans began to cheer him up with the usual hockey chant.

What is a sense of balance?

If you've read about human spaceflight, you've probably noticed that one of the problems scientists have to deal with is the loss of balance more and more as the ship moves away from the Earth's gravity. A sense of balance is the body's ability to adapt to different conditions, depending on its position relative to the Earth, which attracts everything that is nearby from it. Without a sense of balance, birds could not fly, people could not walk, and no living creature could navigate in space.

A person has two organs of balance, and they are located in his head next to each ear. Each of these parts is like a sac and is filled with a fluid called lymph. Inside, these sacs are lined with sensory cells with hairs. When the head is in a vertical position, the pressure on the hairs is the same from all sides, and when tilted to one side or another, it changes. At the same time, sensitive cells are irritated and send impulses along the nerve fibers to the brain. And the brain forces certain muscles to work, which bring the body from an inclined position to a correct, vertical one.

Our balance organs also help us to become aware of the direction of our movement. Imagine that we went for a ride in a car. When the car moves forward, our body involuntarily leans back against the back of the seat. Fluid, or lymph, in the "semicircular canals" of the organs of balance deflects sensitive hairs back. As a result, certain nerves with which they are connected send the appropriate signal to the brain - and we begin to feel that we are moving forward.

So, our body deviates back, and at the same time the lymph moves with it. After some time, sensitive hairs take a vertical position, and we cease to feel the movement of our body forward. Now imagine that the driver has applied the brakes. Our body by inertia still continues to move forward, and the lymph also moves in the organs of balance, tilting the hairs forward now. The corresponding impulse is sent to the brain - and we begin to feel that we are stopping.

In each organ of balance there are three semicircular canals, each of which corresponds to three directions of movement in space. The sensory hairs in these channels help us know if we are moving up or down, forward or backward, right or left.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

The storm is getting bigger 17.05.2021

An analysis of measurements taken from NASA aircraft in 2012 showed that lightning may be a more important means of cleaning the atmosphere than previously thought.

In 2012, these data, obtained from the study of the top of thunderclouds over Colorado and Oklahoma, were considered overestimated. The new analysis, as well as the results of earthly experiments, forced us to reconsider our attitude towards them.

Lightning is known to generate nitrogen oxides and ozone, which indirectly create the hydroxyl radical (OH), the atmosphere's primary oxidant. Recent laboratory studies have shown that the weak and even invisible electrical discharges that accompany lightning flashes generate much more OH and hydroperoxyl radical (HO2) than previously thought - and than lightning itself does.

These laboratory data matched very closely with the 2012 data obtained from a NASA aircraft, which at that time was considered instrumental noise and began to be filtered out during further processing.

This is especially important because, as the planet gets warmer, thunderstorms and lightning strikes are likely to become more frequent, which in turn will affect the balance of greenhouse gases in the air - and, as it turns out, will affect more than scientists thought before, moreover, in a positive direction for humanity.
