Cow with a methane tank

22.03.2010

Argentine biologists have supplied several cows with a balloon that collects methane produced in the complex stomach of ruminants when they digest food. Experimenters claim that a tube inserted into the stomach for several days does not interfere with the animal.

It turned out that a cow weighing 550 kilograms emits 800-1000 liters of methane per day. This gas contributes to the greenhouse effect much more than carbon dioxide. It is estimated that the Argentine cattle population (55 million heads) contributes almost a third of all greenhouse gases emitted into the atmosphere by this country.

Biologists intend to experiment with different types of forage to find ways to reduce emissions.

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, ... >>

Harm of Wi-Fi networks 21.04.2018

An experiment was conducted in Denmark on the influence of Wi-Fi connections and mobile devices on living cells of organisms. The studies were carried out by schoolgirls, but as a result, their studies were of keen interest to respected biologists and radiologists in society.

For the study, the girls laid out about 12 watercress seeds in 400 trays. After that, half of the trays were taken to another room. It is noted that the seeds received the same amount of fertilizer, light and moisture. During the study, schoolgirls installed Wi-Fi routers in one of the rooms. The young scientists reported that they had acquired an installation similar to the type of radiation, which exactly coincides with mobile devices.

The girls' research surprised them, teachers, and scientists alike. In just 12 days, clear signs of harm from radio waves have already been observed. During the experiment, it is noted that the seed sprouts, which were located near the router, looked much worse than those located in another part of the house. It should be noted that most of the sprouts where there was Wi-Fi access died.
