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, ... >>

The phone will tell a lot about its owner 20.11.2016

Of course, your smartphone can give away a lot of your secrets, but it turns out that it can tell a lot about you, even if you do not use the Internet on it and always erase SMS along with your call history.

That film of sweat and grease that covers the screen of any actively used smartphone is essentially your bacterial selfie, and it is not going to put you in the best light.

It turns out that this raid can tell a lot about your life and daily habits. In a recent study, researchers swabbed the hands and phones of 39 volunteers. By simply analyzing the samples in a mass spectrometer (a machine that sorts and identifies chemicals), the researchers were able to tell quite accurately about the lifestyles of everyone involved in the experiment.

For example, the researchers found that one of the participants spent a lot of time outdoors, thanks to the ingredients in sunscreen and insect repellants in the samples. They also quickly identified anti-aging creams, taking medications like antidepressants, a man who had recently been treated for baldness, and even ascertained the subjects' preferred cuisine from trace amounts of herbs and spices in the samples.

If it seems to you that all this is like some kind of crime show, then you are not far from the truth. The study was supported by the US Department of Justice. As the researchers write, forensic scientists may be interested in such methods to determine the location and lifestyle of the offender. But in this way it is also possible to reveal whether a person was exposed to harmful substances that were present in the air at a certain time and in a certain place.

To quickly understand where you've been and what you've been doing on the fly, you need to compile a database that contains the characteristics of most lotions, foods, and other chemicals that we come into contact with on a daily basis. Now such a base does not exist, and it will take quite a lot of effort to create it.
