The rivers of the world are becoming shallow

11.11.2009

According to American hydrologists, between 1948 and 2004, the rivers of Asia and America that flow into the Pacific Ocean reduced their flow by 6%, which corresponds to the annual flow of the Mississippi River.

The rivers flowing into the Indian Ocean have become shallow by 3% over the same period. The Ganges became shallower the most - by 19%. Part of the reason is that man is taking more and more water for his needs. Thus, the amount of water stored in reservoirs around the world and not getting into the oceans for a long time has quadrupled since 1960.

But the main reason, according to experts, is global warming. As a result, precipitation decreases. Only the rivers flowing into the Arctic Ocean become more full-flowing, and this happens due to the melting of ice.

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, ... >>

A new kind of computer sport 10.03.2004

Video games are often criticized for the inactivity of players sitting in front of the console for hours. But in Europe there is a growing community of players who actually shed sweat on a dance floor that is about a square meter in size.

The music video game DDR (Dance Dance Revolution) first appeared in the late 90s and is quite popular in Japan, the United States and Asia. Now it is even considered as a new sport.

The tournament, held last month in London with players from the UK, Norway and Italy, was the first official event held in Europe under community DDR rules. In the competition, the dancers or players step on the colored arrows according to the instructions on the display in front of them. The level of the participant is determined by the accuracy of execution and is evaluated in points.
