The value of dark chocolate for older people with diseased arteries

31.07.2023

Italian scientists conducted a scientific study among elderly patients suffering from peripheral arterial disease. These diseases lead to reduced blood flow, which causes pain and fatigue in the legs or hips when walking.

The experiment involved 20 volunteers, including 14 men and 6 women aged 60 to 78 years. After eating dark chocolate, the participants showed an improved ability to walk unaided.

Eating just one bar of dark chocolate had a positive effect on patients with problems in the arteries of the legs.

Study participants completed the treadmill test twice: first in the morning and then after eating a 40-gram bar of dark or milk chocolate.

The results showed that after eating dark chocolate, they could walk 39 feet (approximately 11,9 meters) further and 17 seconds longer than the first time. The use of milk chocolate did not lead to such improvements.

Researchers attribute the effect of dark chocolate to the presence of polyphenols in cocoa, which improve blood circulation. Dark chocolate contains 85% polyphenol-rich cocoa, while milk chocolate contains 30% less polyphenols.

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, ... >>

Profession choice - by genes 06.04.2010

In one of the schools in Sichuan Province (PRC), genetic testing of children for early career guidance has been introduced.

By swiping a cotton swab along the inner surface of the cheek, the student receives epithelial cells of the oral cavity, on which 11 different genes are analyzed. Among them, for example, genes associated with aggressiveness, enterprise, emotional instability, curiosity for everything new. By the presence and degree of expression of such genes, they try to recommend a future profession to the child.

True, serious geneticists believe that such a test says little and may even be harmful to the fate of the child.
