Summer will be longer and hotter

23.03.2018

Researchers say that the dry and hot period can now last not three months, but as much as half a year. Scientists from Tel Aviv University predict global climate change, which can significantly affect the duration of the summer period.

The fact is that greenhouse gases are the main factor responsible for climate change, and it is directly related to human activities. Israeli scientists, who published their study in the International Journal of Climatology, come to a disturbing conclusion: if human activity continues to influence the climate at the same pace, by mid-century the duration of the summer period will increase by a quarter, and by the end - by 50%.

The dry and hot period in countries such as Israel, Egypt, Lebanon and Turkey will increase to six months, and the rainy season, respectively, will be reduced to two months.

These changes can significantly affect the life of the region: worsen the quality of water resources, change the timing and intensity of seasonal diseases. It is necessary to prepare for climate change, scientists say, since it seems impossible to prevent warming.

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, ... >>

10 trillion frames per second camera 18.10.2018

The capabilities of the new ultra-high-speed camera, developed by researchers from the California Institute of Technology and the INRS organization, far exceed the capabilities of anything that has been created before. This camera is capable of shooting at a speed of 10 trillion frames per second, and this speed is already enough to explore all the subtleties of the processes of interaction of matter with light that occur at the nanoscale level.

Until recently, the record holder for the fastest shooting was a camera created by Swedish scientists last year, capable of shooting at a speed of 5 trillion frames per second. The Swedes, at one time, took the palm from the Japanese, whose camera shot at a speed of 4,4 trillion frames per second. The new camera goes ahead with a margin of two times in terms of shooting speed, and this allows its developers to hope that their offspring will be able to hold out in the first position for quite a long time.

The new camera is based on compressed ultrafast photography (CUP) technology, which, by itself, is capable of shooting at a speed of about 100 billion frames per second. This, of course, is a very high speed, but it is not enough to capture the propagation of a laser light pulse, the duration of which is calculated in femtoseconds, quadrillionths of a second for reference.

The new camera uses two cameras, a femtosecond stripe camera and a static camera, combined into a single system. The operation of the control system is based on the method of obtaining, accumulating and processing data, known as the Radon transformation.
