Rat mutual assistance

22.05.2015

Scientists have established that nobility and empathy are inherent in the body of living beings from birth: the moral attitudes of society are secondary. Experiments to prove this were carried out on rats.

The ability of representatives of the world of fauna to empathy has been studied for a long time. So, in 2011, researchers from the University of Illinois at Chicago discovered the craving of rats to help each other. Some of the experimental rodents were placed in traps, and their "free" comrades made efforts and opened the latches. At the same time, American scientists concluded that rats do this in order not to get bored alone.

A new series of tests was conducted by specialists from Kwansei Gakuin University in Japan. The results are published in the journal Animal Cognition.

The experimental site was a specially designed box consisting of two isolated sections. Water was poured into one of the compartments, placing a rat there. These animals are known to be extremely uncomfortable in the water. The rat could not escape on its own, being in this section - all the possibilities for this were in the rat from the adjacent dry room. A few days after the start of the experiment, the rodents began to open the door, helping the rats floundering in the water. Moreover, the rats who had previously been in a water trap rushed to the aid of their comrade faster than those who had not yet encountered such a situation.

These experiments consolidated the observations of the Americans. The Japanese went further and refuted earlier conclusions. In those experiments, when both experimental rats were in adjacent dry compartments and did not suffer, they did not open the door - that is, they did not need friends as such.

Complicating the task, the scientists put the "dry" rats before a choice: either help a brother who was in the water, or receive a sweet reward. The results were amazing: in most cases, from 50% to 80%, the rats ignored the door, behind which lay a chocolate bar, instead opening the way to salvation for a comrade.

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, ... >>
