Tomatoes and apples treat the lungs of smokers

01.01.2018

Scientists from the Johns Hopkins Bloomberg School of Public Health have shown that the lungs of smokers recover more easily after quitting a bad habit if quitters eat a lot of apples and tomatoes.

Lung function declined more slowly in ex-smokers the more tomatoes and fruits, especially apples, in their diet. The difference is made by at least two tomatoes and more than three fresh fruits a day. The researchers also looked at the effects of canned and cooked vegetables and fruits (including ketchup), but found that they did not have a noticeable effect on lung health. Even in people who never smoked, apples and tomatoes slowed the age-related decline in lung function.

Since 2002, 680 residents of three European countries have taken part in the study (the average age of the study participants was 43 years); all of them answered the questions of the questionnaire and underwent the procedure of spirometric measurement of lung volume and respiratory rate with an interval of ten years. Consumption of different foodstuffs was assessed by appropriate questionnaires.

Scientists attribute the effect to the antioxidants found in fruits and tomatoes; in small amounts, they do not have a significant effect on the body, but long-term dietary intake of antioxidants leads to a significant slowdown in the development of abnormal lung function with age and even reverses the negative effects of smoking in ex-smokers. The authors of the study note that their results should be taken into account by therapists who give dietary advice to smokers.

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, ... >>

It's raining diamonds on Uranus 01.02.2000

A group of physicists led by R. Bendetti from the University of California at Berkeley (USA) subjected a mixture of methane, ammonia and water vapor to a pressure of 10-50 gigapascals at temperatures of two to three thousand Kelvin. Long chain hydrocarbons, amorphous carbon, and small diamonds emerged.

It is these conditions that prevail in the depths of the atmosphere of Uranus and Neptune. Therefore, it is assumed that the solid cores of these planets are constantly raining diamond crystals.
