The world may be left without chocolate

19.11.2016

An international group of scientists has come to the conclusion that soon there may be practically no chocolate left in the world. The reason for this will be a serious infection that affects cocoa trees in Latin America.

Experts noted that Latin America is the main producer and supplier of cocoa beans from which chocolate is made. To date, the problem has not yet had time to cause a serious loss to the "sweet industry". But in a few years, this industry may face serious material losses and a shortage of material.

Africa, a region that is also engaged in large supplies of cocoa beans, can slightly resolve the situation. However, in recent years there has been a drought, which greatly hinders the growth of trees. According to experts, even now the demand for chocolate is starting to grow slowly. This provokes an increase in prices and tougher competition between producers.

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, ... >>

You can get rid of memories 29.09.2012

Fresh memories can be erased, researchers at Uppsala University say in a new paper published in the journal Science. The results are a bright breakthrough in the study of memory and fear. Thomas Agren, a doctoral student in the Department of Psychology, and his supervisors, Professors Mats Fredrikson and Thomas Fürmark, have shown that fresh memories from the human brain can be permanently erased.

When a person learns something new, knowledge is deposited in his long-term memory through a process of consolidation based on the formation of proteins. When we remember something, the memory destabilizes for a while, and then starts the process of consolidation again. In other words, we can say that we remember not what actually happened, but what we remembered the last time we thought about this event. By interfering with the process that follows the memorization of information, we can influence the contents of memory.

During the experiment, volunteers were shown neutral images - landscapes, household items, etc., accompanying the display of some of them with electric shocks. Thus, a certain picture was associated in the memory of the subjects with fear. So, if you show it again, people naturally react to it as a pain. Then the volunteers were divided into two groups - and in one of them, the researchers disrupted the consolidation process by repeatedly showing the participants the same pictures, but without accompanying it with electric shocks, over time, the brain physically fixes the fear in memory.

As a result, associations were fixed in one part of the subjects, while the process of fixing memories was disrupted in the second half, so their memory remained neutral and did not spur the feeling of fear. In addition, using a magnetic resonance scanner, the scientists were able to prove that the physical traces of this memory also disappeared from the part of the brain that stores fear memories - the amygdala in the temporal lobe of the brain.

"These results could represent a major breakthrough in memory and fear research. Ultimately, they could lead to improved treatments for millions of patients suffering from phobias, post-traumatic stress disorder and panic attacks," said Thomas Agren.
