Positive thinking strengthens the immune system

17.11.2021

A group of specialists from the University of Exeter and the University of Oxford (UK) concluded that positive thinking helps to strengthen the immune system.

Scientists conducted an experiment involving more than 135 people. They were divided: some of the volunteers listened to audio lectures on the need to develop positive thinking - to perceive life and the people around them more optimistically, kinder and more condescendingly. Another part of the volunteers listened to the arguments about why the attitude to everything should be as critical as possible.

Volunteers from different groups were measured heart rate and sweating - markers of psychological state. As a result, it turned out that the participants from the "positive thinking" group had their lower parameters, that is, they were more relaxed and less anxious. The level of production of anti-inflammatory components of the immune system in their bodies was also lower, which meant that there was no high risk of infection and disease for a person.

At the same time, the participants in the experiment, who listened to the need for a strict attitude to the world around them, demonstrated increased heart rate and increased sweating. According to doctors, such signs appear when there is a feeling of danger and insecurity, increased stress.

"Positive thinking significantly calms the heartbeat and strengthens the immune system, while negative thoughts have a negative impact not only on the psyche, but also on the physical condition of a person. When we learn not to react painfully to external threats, we strengthen our immunity, thereby increasing chances of recovery," the researchers said.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

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 ... >>

Ultra-strong aluminum alloy created 21.01.2018

Specialists from Purdue University (USA) have created a new aluminum-based alloy, which is as strong as steel and can be used as an anti-corrosion coating. To do this, aluminum changed the crystal structure.

The fact is that any metal consists of layers of crystals. But if there is a “laying defect”, due to which several layers are missing, the material is stronger. University specialists tested this in practice by creating aluminum with missing layers in the crystal lattice. True, it was not easy, because aluminum has a high stacking defect energy, that is, it is able to repair defects on its own.

To solve the problem, a laser was used to bombard ultrathin aluminum films with silicon dioxide particles. The second method is magnetron sputtering, which makes it possible to introduce iron atoms into the aluminum crystal structure.

The results showed how to make aluminum alloys that are comparable or even stronger than stainless steel. This discovery has great commercial potential.

Thus, the resulting material may be one of the strongest ever made by man. But, more importantly, the technology can be mass-produced.
