People love naughty cats

23.08.2022

In a recent study, experts found that, in fact, the relationship between a cat and a person has a positive effect on people. One ironic reason is that some cat owners enjoy it when their pets misbehave.

Cats can be little monsters, but some people love them for that. In a new study, experts looked at the psychopathic traits of domestic cats, including arrogance, meanness and disinhibition. This behavior can be annoying if a person behaves like this, but not a domestic cat.

In total, the experts conducted 3 experiments and found that owners liked it when their cats showed disinhibition, such as jumping around carelessly, and also, oddly enough, unfriendly towards other pets.

"In fact, these behaviors tend to promote more interaction and emotional closeness with the cat owner. That pet dislike showed higher quality relationships was a little unexpected for us," said researcher Rebecca Evans from the University of Liverpool.

However, cat owners disliked all psychopathic traits in cats, including arrogance and meanness, which led to negative relationships. How the owners will perceive the naughty and chaotic behavior of cats depends on their relationship.

Another reason for such love is that the cat not only improves the life of the owner, but also helps him cope with a stressful situation. A cat exhibiting excessive negative tendencies can be very distracting to the owner. It's also worth noting that people's acceptance of cats' erratic behavior may be related to how they perceive their furry.

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, ... >>

Microbes recognize letters 06.06.2021

Thanks to their recent discovery, scientists from the Technion's Department of Biomedical Engineering have been able to achieve the recognition of certain geometric patterns - like letters - by colonies of microbes that mimic an artificial neural network.

The method of scientists is based on changing the way of communication within the colonies of microbes in nature. Research conducted by Dr. Siming Lee and Associate Professor Ramez Daniel.

Professor Daniel's laboratory is engaged in synthetic biology, in particular, the creation of biological circuits that essentially combine the principles of biology and electronics. Like electronic switches that can be turned on and off, cells are designed to "turn on" and perform a function, such as fluorescence, in response to a specific stimulus. Using this technique, the group has developed biological "sensors" that detect the presence of arsenic and other poisons in water or the presence of blood in urine.

However, cells are capable of performing more complex functions than a simple yes/no switch. Colonies of microbes in nature are capable of internal communication. For example, they may react differently to external stimuli when there are few colonies or when there are many of them. This phenomenon, called "quorum sensing," also occurs, for example, when our immune system mobilizes against an infection - cells transmit information about which pathogen has entered the body, what response is required, and much more.

One cell by itself may be "stupid", but the whole colony is usually "smart". It is this phenomenon that Professor Daniel's group used to multiply the algorithmic complexity of the task and for the first time create a biological circuit that acts as an artificial neural network capable of performing a relatively complex task: pattern recognition. Its building blocks are modified E. coli bacteria.

The geometric patterns created in this way are a proof of concept for what biological circuits can do, acting like an artificial neural network. In the future, we may see bioengineered systems that track toxins, diagnose cancer, and use them to regenerate tissues. We may even have biological computers. It is interesting to see how synthetic biology, which seeks to mimic the electronics in biological systems, has come full circle, creating a kind of artificial neural network that is, of course, inspired by the human brain, the most complex biological system.
