coffee protects the heart

04.07.2018

Four cups of coffee a day can help reduce the risk of a heart attack and help you recover faster from a heart attack. Caffeine also protects against type XNUMX diabetes and other heart diseases. Scientists from the Heinrich Heine University Düsseldorf (Germany) conducted a study on mice, which helped to explain the reason for such a beneficial effect.

During the study, for ten days, scientists added to the drinking water of a group of mice an amount of coffee that corresponds to four cups per day for a person. They then artificially induced a heart attack in the rodents. Damaged myocardial cells in mice that received caffeine recovered better from an attack than those of mice that drank plain water.

The healing property of coffee is explained by the fact that caffeine stimulates the work of the p27 protein in the mitochondria - the "energy station" of the cell. Activating p27 in mitochondria increases the organelle's energy production, and this helps myocardial cells repair after damage, the team has shown. Humans and other animals also have the p27 protein, raising the possibility that caffeine may be good for the human heart as well. Normally, p27 controls cell division and suppresses the development of tumors. Its energetic role in mitochondria was not previously known.

The discovery goes against the grain of doctors' belief that coffee is contraindicated for people with heart disease, so it still needs to be scrutinized. In addition, researchers from a German university warn that frequent coffee consumption alone - without exercise and proper nutrition - will not bring many benefits and may cause health problems.

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, ... >>

Noise curtains 15.05.2000

Anti-noise fabric, which is a multilayer, but rather thin sandwich of sound-absorbing materials, was created at the Georgia Institute of Technology Research (USA).

The new fabric drapes reduce street noise by seven decibels (a 3 decibel reduction means it is halved). Some American hospitals have already equipped their wards with such protection.
