Black caviar from Switzerland

07.07.2010

Switzerland is known for its cheeses and chocolate, but sturgeon caviar can join the specialties of this country. In the town of Frutigen (40 kilometers south of Bern), a large greenhouse complex has been operating for two years, heated by warm water, which has to be constantly pumped out of the railway tunnel under the Alps, one of the longest in the world.

The tunnel was opened in 2007, and it turned out that underground warm water seeps into it, which cannot be dumped into the local river without cooling, so that the trout do not die from overheating. Bananas, mangoes, papaya and other exotic fruits ripen in greenhouses.

Recently, 60 pools were built here, each of which was filled with about a thousand Siberian sturgeon and sterlet. The goal is to achieve an annual "harvest" of 50 tons of sturgeon and three tons of black caviar.

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, ... >>

Monitor Iiyama ProLite X3291HS 14.12.2015

Iiyama has expanded its family of monitors with the ProLite X3291HS model, which has a diagonal of 31,5 inches: sales of new items will start in the near future.

The novelty is made on the AH-IPS matrix. The resolution is 1920 x 1080 pixels, which corresponds to the Full HD format. Response time - 5 ms.

The panel has a brightness of 250 cd / m2, a contrast ratio of 1000:1 (dynamic contrast ratio reaches 12:000). The horizontal and vertical viewing angles are 000 degrees.

Blue Light Reducer technology reduces blue light intensity. This reduces the load on the visual apparatus and reduces eye fatigue. In addition, the panel boasts no flicker.

To connect signal sources, an analog D-Sub connector, digital DVI and HDMI interfaces are provided. There are 3-watt stereo speakers. Dimensions are 737,5 x 240 x 523,5 mm, weight - 7 kg.

It will be possible to buy a novelty at an estimated price of $ 320.
