Animals see human anger

21.02.2016

Dog lovers often say that their pets literally understand the feelings of their owners. Of course, dogs are unlikely to have the ability to read minds, but they can read emotions quite well. Dogs are able to distinguish between different emotions: they look at a neutral facial expression differently than they look at an angry face or a face expressing pleasure.

Zoologists also noticed that animals reacted differently to a threat, depending on whether it came from a dog or from a person. If the threat came from another dog, then the one who looked at him continued to look further, but if the animal was shown a human face, the expression of which did not bode well, then the dog quickly looked away. Probably, a long cohabitation with a person taught the dogs to read our emotions and demonstrate obedience in advance, trying to calm down a obviously more developed and stronger opponent.

But not only dogs, it turns out, recognize human emotions (we are not talking about primates now). Karen McComb and her colleagues at the University of Sussex found that horses can also see the mood we're in. The experiment was carried out as follows: the animals were shown photos of two dissimilar men, who had happiness or anger written on their faces. The horses were not prepared for the test in any way, the researchers were interested in their spontaneous reaction. The experimenters themselves also did not see what they were showing - they recognized it only after the horse reacted to the photograph (it was done so that the person inadvertently did not provoke the animal to any reaction by his behavior and did not distort the results).

The results were the following: the horses turned to the "evil" photos with the left side of their head, their heartbeat immediately increased and in general they behaved as if under stress. It is known that many animals look at danger with the left eye, because the brain centers responsible for analyzing the threat and finding possible ways out of the situation are located in the right hemisphere (and information from the eyes, as you know, goes along the crossing nerve pathways from left to right and right left). Dogs, for example, also prefer to see the "negative facial expression" with their left eye. By the way, horses generally reacted more indifferently to happy photographs, which, in general, can be easily explained: horses do not need our happiness, a person with an evil face clearly poses a threat, and a happy one, well, rejoices and rejoices.

However, there is no doubt that they were in principle able to distinguish one facial expression from another - this is somewhat unexpected for animals, which are still not in such close relations with us as the same dogs. It is possible that horses acquire such a skill during their life, communicating with people from birth. Although it may be otherwise - that their own emotion recognition system, necessary for communicating with each other, in the course of evolution has learned to analyze not only horse "faces", but also the physiognomies of Homo sapiens.

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 ... >>

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 bird flies out and helps catch the robber 18.10.2001

Experienced photographers know that when you're shooting a dog or a small child, snapping your fingers or whistling to get your subject to look directly at the camera is a must. A purely instinctive reaction to search for the source of an unexpected sound is triggered (academician Pavlov called it the "what is it?" reflex).

Professor Deborah Widington from the University of the English city of Leeds suggests using a similar method to catch criminals. TV cameras placed in shops and banks do not always catch the image of a robber in full face.

For more successful video shooting, you need to combine a camera with a speaker that emits a specially synthesized sharp sound with a wide frequency spectrum at the time of shooting. As experiments have shown, it is simply impossible not to turn to him, and a recognizable portrait of a robber is almost guaranteed.
