The oceans are rapidly cooling

06.01.2019

After some study of the oceans, scientists from Woods Hole Oceanic and Harvard universities came to the conclusion that at the moment the weather on the planet is the same as in 1870.

The Pacific Ocean, the waters of which were studied, is characterized by a weak current, so the upper layers of water there sink down only after 200 years. Therefore, the temperature of the water at a depth of about two kilometers allows us to find out how cold it was two centuries ago - at the time when the Little Ice Age ended.

At the moment, the World Ocean is cooling down again: the temperature of the upper layer in the Pacific Ocean has decreased by 0,08 ° C. This process began at the end of the last century. When it will stop, it is impossible to say.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Night milk is healing 04.07.2005

Finnish dairy farms are producing a new product: night milk.

It turns out that if you milk a cow at night or in the morning, but in a darkened room, the milk contains 10 times more melatonin, the sleep hormone, than in ordinary morning, afternoon or evening milk. Melatonin is also produced in the human body, but with age and under the influence of stress, its secretion is greatly reduced. Therefore, drinking a glass or two of nightly milk before bed is recommended for all older people and those who find it difficult to fall asleep.

The novelty is in great demand in Finland. Hundreds of farms have switched to night milking, especially since the new sort of milk is noticeably more expensive than usual. In addition, physiologists have found that night milking increases the fertility of cows.

But in Switzerland, where a farmer tried to take advantage of the Finnish experience, night milk was banned shortly after it appeared on store shelves. The reason is the strict Swiss laws on food, drugs and dietary supplements. A food product cannot be claimed as a remedy for disease or a means of preventing them, and even a mild form of insomnia is considered a disease by law.

High levels of melatonin should not be reported on milk bottles, as melatonin is a hormone, hence a drug. Perhaps later in Switzerland they will be allowed to sell night milk in pharmacies.
