Cat face expression

04.11.2023

Scientific observation of 53 adult domestic cats revealed that these animals have no less than 276 different facial expressions when communicating with each other. While accurately deciphering the meaning of these expressions appears to be a difficult task, scientists were able to identify about half of them as expressions indicating a friendly mood.

Two researchers from the University of Kansas and Lyon College note that while the facial expressions of domestic cats (Felis silvestris catus) are increasingly being studied, this most often occurs in the context of interactions with humans. However, communication between members of their own species can be more complex and unique. The researchers took advantage of living close to a cat cafe in Los Angeles, where coffee could be enjoyed in the company of dozens of socializing cats. After staying there for a year after the establishment closed, the scientists documented 192 minutes of interactions between 53 cats.

After analyzing the recordings, the researchers identified 276 unique combinations of facial muscle movements in cats, corresponding to various expressions. In 45 percent of cases, the facial expressions were associated with friendly communication between cats, while in 37 percent of cases they clearly indicated hostile intentions. The remaining 18 percent were characterized by scientists as expressions that fell between the two types.

The ancestors of domestic cats led a solitary lifestyle, but the process of their domestication led to an increase in the frequency of contacts between them. This may be why domestic cats have evolved the ability to demonstrate a variety of intentions using facial expressions that are predominantly positive, thereby facilitating the formation of social bonds.

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, ... >>

Larva meat substitute 29.08.2022

South Korean scientists have created a meat substitute from the proteins contained in the body of flour beetle larvae and sugar. These insects are commonly used for laboratory experiments or as food for small animals.

According to a professor at Wonkwan University in Iksan (South Korea) Cho Inhee, the increase in meat prices, as well as the problem of global warming, are forcing the modern world to seriously consider the possibility of eating various insects.

"We hope that the method of processing flour beetle larvae developed by us will lead to the emergence of artificial analogues of meat and "meat sauces" based on these insects," the scientist expressed hope.
