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, ... >>

Artificial light fills 21.05.2015

We know that in addition to "bad" fat, there is also "good" fat. We are talking about two types of adipose tissue, white and brown: if white fat cells store fat molecules, thereby causing us to get fat, then brown fat cells, on the contrary, burn fat reserves with the release of heat. Since it turned out that brown fat is present not only in animals and infants, but also in adults, it has been actively studied, trying to find a way to stimulate the activity of brown adipose tissue cells - so it would be possible solve the problem of obesity and its accompanying metabolic and cardiovascular diseases.

There is no shortage of suggestions here: brown fat is affected by hormones, immune cells, and special neurons; in addition, you can activate it with physical exercises or simply by going out into the cold (as we just said, fats in it are burned with the formation of heat, and one of the functions of brown adipose tissue is thermoregulation). Researchers from the University of Leiden have found a very simple way to keep brown fat in good shape - it turns out that you just need to sit less in the evenings in artificial light.

It is known that the stimulation of brown fat occurs with the participation of the b3 adrenergic receptor - when it is activated, the cells burn more lipids and generate more heat. Patrick Rensen and his colleagues found that if mice are kept under artificial light for 16 or even 24 hours a day, their receptor activity decreases, and, accordingly, brown fat cells begin to work worse, and lipid molecules are sent into storage white fat. With mice in which daylight hours lasted the standard 12 hours, nothing like this happened. (Mice are crepuscular animals, which means that daylight hours are like night for us.) As a result, mice kept in the light for a long time accumulated 25-50% more fat, although animals from all groups were fed the same amount of food and physical activity. they were also the same.

Of course, the point here is not in the artificial light itself, but in the daily rhythm, which deteriorates due to illumination at inopportune times: the biological clock says that it should be night for a long time, but the eyes continue to see the light. Of course, we will still fall asleep, albeit with artificial lighting, but this will still be reflected in the biological clock. It is known that even if you go to bed at the right time, it is still bright lighting that accompanies us to the last, in itself can cause harm. Well, the fact that a disrupted circadian rhythm is associated with obesity has long been confirmed by both experiments and clinical studies. According to some reports, too long daylight hours provokes obesity even more than malnutrition. And, apparently, the effect here is not least due to the improper functioning of brown fat. Its interaction with the biological clock in the brain is carried out through the sympathetic nervous system: if brown adipose tissue was disconnected from the sympathetic nerve pathways, then the effect was the same as with a circadian rhythm disorder - brown cells stopped burning lipids.

Whether there is a similar relationship between brown fat activity and circadian rhythm in humans remains to be seen. Similar results were obtained two years ago by specialists from Vanderbilt University, who found that insulin sensitivity in cells depends on the time of day, and that when the circadian rhythm is disturbed, cells begin to live on glucose alone, laying fat in reserve. The result is overweight. These experiments were also done on animals; on the other hand, we repeat, medical statistics show that in humans, a disturbed circadian rhythm is often accompanied by various bad physiological effects, including in metabolism. Also here one cannot but recall an article published at the end of last year in the Proceedings of the National Academy of Science, which discussed how the radiation from the screens of electronic devices confuses our biological clock.

In general, those who want to lose weight can be recommended not only to eat right, but also to go to bed on time - or at least not to abuse all kinds of gadgets before going to bed.
