Cats understand their owners

19.04.2023

Many pet owners believe that their pets understand everything that is said to them. And scientists from Sophia University in Tokyo have found evidence that cats can actually understand human language.

The researchers studied the behavior of 78 cats and found that cats can distinguish their nickname from other words, even if it is pronounced with an accent. They are able to match words with individual objects, which indicates a high understanding of the language.

However, scientists also note that these skills depend on the individual characteristics of each feline personality and its level of intelligence. Even among cats, there can be disagreement about the ability to understand human language.

Domestic cats are also very good at reading the mood of their owner and behave accordingly. They may be cautious in communication or try to fawn. It may seem that the cat perfectly understands what is being said to him.

In addition, cats also understand that young children do not always understand the consequences of their actions. Therefore, they may avoid contact with children because they are afraid that they might harm them.

Cats are also well aware of the prohibitions set by their owner. They can observe these prohibitions, but only in the presence of the owner. But, like other animals, they have no concept of good and evil. That is why they will observe the prohibitions only in the presence of the owner.

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 age of the solid core in the center of the Earth is determined 09.02.2019

Earth's magnetosphere extends far into space and deflects most of the high-energy particles that would otherwise bombard our planet's surface, rendering it virtually uninhabitable. Geomagnetism arises deep in the bowels of the Earth, where a solid iron-nickel core is located, heated to almost 5500 ° C. It is surrounded by a thicker and more liquid outer core, the material of which continuously cools and settles, building up solid layers in the center. This causes the conductive hot alloy liquid core to stir and create a geomagnetic field.

Once the earth's core was heated more strongly, it remained entirely liquid and seethed, generating a magnetic field. However, its temperature gradually decreased, mixing slowed down, and the magnetosphere weakened to a level dangerous for life on the planet. Fortunately, at some point, a solid core began to form in its center, which gave the Earth's "magnetic dynamo" a new strength. Various models place the event between 0,5 and 2,5 billion years ago, but a new study by geologists led by University of Rochester professor John Tarduno puts the date fairly accurately at 565 million years ago.

Indeed, the core of the Earth remains inaccessible to direct research, however, all changes in the global magnetic field are imprinted in the orientation of the particles of certain minerals. Scientists analyzed it in crystalline pyroxenes and spars found under the town of Sept-Iles in Quebec, Canada and dated to 550-600 million years old. The crystals showed that in that era the magnetosphere was going through hard times, weakening and changing polarity ten times faster than it happens in the modern era. However, from a certain moment the process stopped and suddenly began to develop in a completely different direction. The magnetic field began to intensify.

Interestingly, this time coincides with the end of the Ediacaran period, which culminated in one of the global extinctions of the biosphere: judging by the data of Tarduno and his colleagues, it could well be caused by the weakening of the magnetosphere. By the way, some previous data also pointed to this. The subsequent restoration and strengthening of the magnetic field coincided with the next important stage in the evolution of life - the Cambrian explosion of biodiversity, during which the ancestors of all modern animal types appeared. Perhaps it was the increased bombardment of the planet by cosmic radiation that contributed to the survival and development of new life forms - mobile, capable of going to the depth of water, or well protected by a shell or exoskeleton.
