Tea is good for the brain

19.01.2023

It has been proven that drinking tea has a positive effect on brain function and allows you to better cope with creative tasks.

Researchers at Peking University conducted a series of experiments to see if tea could improve brain intelligence and so-called convergent thinking. It is the kind of thinking we use to solve problems. The findings show that regular consumption of tea benefits the intellect, as well as many other health benefits, to which one can add an increase in life expectancy.

The results of the experiments showed that tea is especially good at helping to cope with complex tasks. Moreover, tea lovers are particularly resilient in the sense of solving these problems, and at the same time they do not get tired.

The experiments involved 100 people who went through tests for vocabulary associations or other linguistic tasks of varying complexity. Each participant was given the opportunity to drink a cup of water or a glass of tea at the same warm temperature.

Tea drinkers were found to perform better on tests than water drinkers, especially when complex creative thinking was required. But at a low level of complexity, the influence of tea in this matter was minimal.

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, ... >>

Soft electronics has become multi-layered 22.08.2018

Soft PCBs could change the way we think about electronic devices. Flexible and soft electronics will allow you to create medical sensors that you can comfortably wear on yourself without fear of breaking. But how soon will we have such devices?

Various research groups have repeatedly demonstrated prototypes of soft electronics. As a rule, in such cases, they try to combine existing electronic components with a soft and durable substrate, or they try to create new flexible transistors and microcircuits. The employees of the University of California at San Diego have taken another step towards the release of "electronic-soft" technologies beyond the walls of laboratories. They took the first path by incorporating microscopic components into elastomer substrates, a polymer with high elasticity and viscosity.

However, unlike previous attempts, this time the soft board was made multi-layered. Previously, this did not work: the main difficulty was that it was not possible to create strong electrical connections between the layers. In ordinary, solid boards, this is no longer a problem, modern printed circuit boards can have several dozen layers, and the power of devices can be increased without changing their size.

To create a soft "layer cake", Zhenlong Huang (Zhenlong Huang) and his colleagues used laser technology: holes were burned into the thinnest elastomer substrates and then filled with a conductor material. Inside the layer, the components are connected using flexible copper threads twisted into spirals, which the authors of the work called "bridges"; There were four layers in total.

A soft device the size of a coin was literally stuffed with functions: a wireless communication module and a whole set of sensors (accelerometer, etc.) fit in it. A soft board was attached to the neck, head, hands, which made it possible to take an electroencephalogram, monitor heart rate and breathing. With the help of the board, it was also possible to control the robot's hand, tracking nerve impulses in the hand of one of the researchers: the robot moved its "fingers" and "hand" after the person.

In the future, the California laboratory intends to further increase the number of layers. Perhaps thanks to this technology, amazing new medical devices and all kinds of agile and agile soft robots will appear faster than we think.
