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, ... >>

Israeli Butterfly Drone 19.01.2013

Israel Aerospace Industries (IAI) is developing a miniature butterfly unmanned aerial vehicle. The device weighs only a few grams and can stay in the air for 20 minutes. Now an Israeli company is working on two winged prototypes: a small "butterfly" weighing eight grams and a large one, whose mass reaches 13 g. The devices are powered by a compact lithium-polymer battery weighing two grams. Each UAV is equipped with a microvideo camera weighing only 0,1 g.

The drones are driven by a compact electric motor running at 7000 rpm. The commands of the UAV operator are responded to using a flight control system with a mass of 3 g. The wings of the "butterfly" are made by hand from transparent carbon fiber. With the start of serial production of UAVs, components for drones are also planned to be put on the conveyor. Butterfly drones are expected to be used, in particular, in hostage-taking situations. Thus, the UAV equipped with a video camera and microphone will be able to discreetly reconnoiter the situation in the incident area.

According to Flightglobal, IAI engineers are creating a drone under the slogan "if nature can, we will try to imitate it." Work on the device began with the creation of a four-winged prototype, similar to a dragonfly. In the future, it is planned to teach the UAV to fly only on two wings. For this, in particular, it is required to correct the amplitude of their oscillations. As the interlocutor of the publication explained, this will take several months.

Earlier it was reported that Israel, with the support of the United States, is conducting research on the creation of cyborg insects. During the tests, scientists study the mechanics of the movement of flies, grasshoppers, beetles and dragonflies. It is also planned to use cyborg insects for reconnaissance purposes.
