What circumstances of victory at the Olympics are fixed in the Australian idiom?

Australia's first gold medal at the Winter Olympics was won by short track skater Stephen Bradbury in 2002. At all previous Olympics, the athlete did not go beyond the preliminary stage, but here in the quarterfinals he took third place and advanced to the next round due to the disqualification of the winner of the race. In the semi-finals, he was last, but finished second due to collisions and falls in front. A similar story was repeated in the final, where all of his competitors had already fallen, thanks to which Bradbury won. Effortless success is anchored in the Australian expression "doing a Bradbury".

How do our muscles work?

In our body, there are special cells that make up connective tissue - the tissue that connects all parts of our body together. Not all connective tissue cells can contract or shrink. But in some areas of the body, these cells can shrink to the point where they turn into muscle cells. Wherever muscle cells find their way into the body, they are numerous and bundled together to form individual smooth muscles made up of fibers.

There are a lot of smooth muscles in our body, and they help various organs to function. For example, smooth muscles close and open your eyes, regulate your breathing, and carry out internal functions. With development, smooth muscle fibers are transformed into muscles of a different shape, which are called striated.

The human body consists of 639 muscles. The flesh of the body is the muscles. Muscles are also the red meat that we buy in the store. Muscles come in different sizes and shapes. A medium-sized muscle consists of approximately 10 million, and the entire human body of 6 billion muscle cells! Each of these 6 billion muscle cells is like a ten-cylinder engine.

Cylinders in cells are tiny liquid capsules. When a signal from the brain enters these capsules, the muscles contract. In a fraction of a second, the liquid in the capsules thickens and then liquefies again. This process causes the muscles to move. Without striated muscles, our body would not be able to move.

For example, the muscles that control the process of digestion act independently of our desire. The muscle reaction is very fast. The muscle contracts in 0,1 sec. This is immediately followed by muscle relaxation. These cuts are repeated over and over. They happen so fast that the smooth muscles act continuously!

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

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 ... >>

Optimists are not afraid of a heart attack 21.07.2013

Cheerful people are much less likely to suffer a heart attack and die less often from sudden heart failure, according to a new study by scientists at Johns Hopkins University (USA).

Previous studies have already shown that depression and anxiety can trigger a heart attack. But researchers at Hopkins University have confirmed that it is important to stay healthy not just not to become discouraged, but to be cheerful and energetic. The happier a person is, the happier he feels, the lower the likelihood of developing coronary heart disease.

According to scientists, optimists are more likely to live a long and happy life. The feeling of happiness, good mood and cheerfulness have a positive effect on the state of our body and allow us to stay healthy longer. At the same time, scientists warn that this is more likely not about an artificial attempt to force oneself to look at the world positively, but about innate cheerfulness. That is, if a person is lucky to be born an optimist, then his health is at less risk. If a person, on the contrary, is a pessimist, he will not be able to improve his health even with the best mood.

So far, researchers have no explanation for the mechanism that allows optimists to stay healthy for longer. However, statistics show that the risk of heart attack in cheerful people is still less.

Scientists analyzed data on patients with cases of coronary heart disease in the family. The study was carried out for 25 years. All this time, 1483 people were observed by doctors, whose brothers or sisters under the age of 60 suffered a heart attack (as a rule, such people are at risk for developing heart diseases, in particular coronary heart disease).

Especially for this study, patients filled out a questionnaire describing their mood, the presence or absence of anxiety, the level of life satisfaction, etc. During the 25-year follow-up, 208 cases of coronary heart disease occurred in patients - heart attacks, sudden death, acute coronary syndrome. In addition, some patients needed stenting and bypass surgery.

The researchers found that in the group of optimistic participants, heart disease occurred a third less often. And among those optimists who were at high risk for developing cardiovascular disease, the decline was about 50%.

To test their findings, the researchers looked at other people's data. They looked at the medical records of 5992 people. The history of the 16-year follow-up suggests that in this case, too, optimists were much less likely (13%) to suffer from coronary heart disease.
