The Amazon is drying up

07.10.2006

In the autumn of 2005, hydrologists noted a record low water level in the Amazon in northeastern Peru, near the city of Iquitos.

Compared to the usual average level, the water dropped by about 3 meters. According to Fernando Rodriguez of the Amazon Research Institute in Peru, this is a consequence of the destruction of forests along the banks of the great river and its tributaries.

More than 10 million hectares have already been cut down, as a result, the amount of rainfall has decreased, not only in this region, but also in North America, all the way to Texas. The rate of deforestation is only increasing.

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 black hole can become a portal 07.09.2020

Scientists have proposed how to make a portal out of a black hole. We are talking about a stable tunnel that can accommodate a spaceship, despite the fact that for a long time the wormholes were either too small or too unreliable.

Research in this direction was carried out by specialists from Princeton. Scientists have found confirmation of the possibility of creating a "wormhole" in space, which will be enough, among other things, to fit a full-fledged ship. In such a wormhole, one can travel, not only through space, but also through time. A starship would be able to travel to distant points in the universe in moments, but by earthly standards, such a "journey" would take thousands of years.

At the same time, the contents of black holes are still unknown to mankind. In this regard, its surface is called the "event horizon". Getting to the latter would require anti-gravity acting as a repulsive force. A similar property should have a substance known as exotic matter. It is assumed that everything is not the way people are used to. For example, a piece of such matter can have a weight of minus 3 kg.

The authors of the new work admit that it is possible to obtain one from particles known as massless fermions, which do not have weight, like photons. Due to their lightness, they manage to fly at the speed of light. Scientists admit that there are five dimensions, and a wormhole leads through one of them.
