What emotions of a dog can be recognized by the nature of the wagging of its tail?

When a dog wags its tail, it can mean more than just joy and friendliness. The dog's positive emotions are most evident when the waggle is asymmetrically shifted to the right. But if the movements of the tail shift to the left, this means that she has met something frightening or annoying. Moreover, dogs not only convey their emotions in this way, but also recognize the gestures of other dogs. When showing a video recording of relatives with a left-handed tail wag, the devices detect a rapid heartbeat and signs of anxiety in dogs, and when a wagging to the right is shown, no changes in the behavior of the experimental subjects are observed.

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 ... >>

Wavy transistors 16.02.2006

Scientists at the University of Illinois have made harmonica-like transistors.

To make semiconductor harmonicas, scientists from the University of Illinois (USA), led by Professor Yongan Huang, deposited ultra-thin strips of semiconductor devices from single-crystal silicon onto a standard silicon substrate. Then, using etching, they were cut off, obtaining ribbons 100 nm thick, and a sheet of stretched rubber was placed on top. Silicon strips stuck to it and separated from the substrate.

When the rubber sheet shrunk, the result was a wavy surface similar to accordion bellows. Like a real accordion, it can be squeezed and stretched many times, and this does not affect the operation of semiconductor devices.

"Expandable silicon diodes and transistors are just two examples of wavy electronic devices that can be made with our technology," says Yongan Huang. artificial human muscles or tissues".
