Meditation speeds up the brain

15.08.2021

Scientist Weiying Daiem found that regular meditation for eight weeks will help the brain work faster and easier.

The reason for the study was a conversation between a scientist and Ph.D. George Weinschschenk. The philosopher's wife and he himself are long-standing practitioners of meditation, so these people have serious knowledge in this area.

While testing the theory, Weiying decided to try the new method and taught his students to meditate for 10-15 minutes for eight weeks, after which he began to track their results. As a result, it turned out that this practice really helps our brain to work better.

Students became faster and better at focusing on a task, as well as doing it much faster. In addition, the level of self-development improved in the subjects, and mental pliability began to increase.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

Smart windows based on the octopus organism 13.02.2023

People came up with the idea of ​​building houses and buildings to be less dependent on the weather and the environment. However, maintaining comfortable conditions inside requires continuous expenditures for lighting, heating or cooling. According to 2021 data, they account for 30 percent of the world's energy consumption, generating about a quarter of all greenhouse gas emissions. And the ongoing global warming only increases these figures.

The main channels through which buildings heat up in the heat and cool in the cold are windows. They let rays of different wavelengths pass through, and together with the light, heat inevitably penetrates inside - or is lost in vain, leaving for the street. Therefore, scientists and engineers are trying to create more technological glass that would not interfere with natural light, but at the same time would block other types of radiation. For example, they can automatically dim in bright light.

However, such solutions are not flexible enough, and ideally, the window should be able to change bandwidth flexibly. Such a window can become transparent only for certain waves, adjusting to the conditions in order to provide both the necessary illumination and minimal energy loss. Just such a solution was recently demonstrated by a team from the Canadian University of Toronto.

Benjamin Hatton and his colleagues demonstrated a prototype made of transparent plastic, between the layers of which a network of tubes with a diameter of about a millimeter is enclosed. A liquid with pigments is pumped through them, making the "glass" opaque for a certain range of radiation. The "window" uses several such layers, each of which has its own pigment solution with its own characteristics. By controlling the flow of fluid in them, it is possible to change the throughput of the entire system.

According to scientists, this solution is borrowed from nature. More precisely, the skin of octopuses, famous for their ability to change color. This is achieved by a multilayer structure containing pigment-filled chromatophore cells. Their "tuning" allows you to change the characteristics of absorption and reflection of radiation, flexibly changing the appearance and color of the animal.

Based on the characteristics obtained from the prototype test results, the authors calculated the potential economic effect from the use of such "windows". According to these estimates, even a single-layer system that controls the passage of NIR waves will reduce heating and cooling costs by 25 percent. And if you add a layer responsible for the radiation of the visible range to it, then the savings can already reach 50 percent.
