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 ... >>

Depression and anxiety change brain volume 17.08.2020

Scientists from Australia have found that depressive and anxiety disorders can cause serious physiological changes in the human brain. Mental problems can reduce certain areas of the brain while increasing others.

Experts from the Australian National University studied the mental organs of more than ten thousand people, paying attention to the volume of different areas of the brain. Comparing the results of the study with data on depressive and anxiety disorders of the participants, the scientists noticed that mental problems can affect the volume of different parts of the brain.

"Chronic depression reduces the volume of the hippocampus. This area of the brain plays a significant role in the processes of memory and learning. If depression is accompanied by anxiety (and this happens very often), then the amygdala increases - the area of \uXNUMXb\uXNUMXbthe brain that is responsible for emotions," says Dr. Daniela Espinoza Oyarse, lead author of the study.

A reduction in the volume of some areas of the brain and a simultaneous increase in the volume of others creates the illusion that the total volume of the brain does not change in depressive and anxiety disorders. However, a new study has shown that psychological problems can more than noticeably affect the physical condition of the thinking organ.
