Memories warm both the soul and the body

14.12.2012

Nostalgia warms the soul. Oddly enough, this turned out to be true not only in a figurative sense. Memories of bygone days, as the experiment of scientists from the University of Southampton showed, can actually make us feel physically warmer.

A study published in the journal Emotion examined the impact of nostalgic memories on our physical responses to cold and heat. In total, the experiment consisted of several stages. To start, the participants were asked to simply write down their nostalgic feelings and spontaneous memories for 30 consecutive days. It turned out that the memories themselves occur more often and last longer on colder days. In the second experiment, the participants were placed in three rooms - cold (20 degrees C), comfortable (24 degrees C) and hot (28 degrees C) and were asked about their memories and feelings. Volunteers in rooms with comfortable and elevated temperatures did not differ from each other, while volunteers from cold rooms more often indulged in pleasant memories of the past.

Participants were then asked to sit indoors and spend time reminiscing about nostalgic or ordinary events in their lives. After that, they were asked to guess the temperature in the room. Those who experienced nostalgia perceived the temperature to be higher than it actually was. Similarly, volunteers were asked to soak their hands in ice water for as long as they could handle. If nostalgic memories were activated at this time, they kept their hands in the water longer than others.

“Nostalgia is a frequent experience, and all we knew so far is that it is able to maintain a certain psychological comfort,” said Dr. Tim Wildshut, senior lecturer at the University of Southampton and co-author of the study. “But now our research has shown that nostalgia has a homeostatic function. and allows the body to model the bodily state through mental experiences. It may turn out that nostalgia can increase our adaptation to other types of physical discomfort, in addition to low temperatures.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

New application for the hydrogen engine 13.01.2019

American truck manufacturer Kenworth and Toyota North America have released a pilot batch of ten hydrogen-powered tractors based on the Kenworth T680.

The car was created with funds from the California Air Resources Board, which provided a $41 million grant for research and development aimed at reducing emissions of harmful substances from motor vehicles in Los Angeles. In this case, we are talking about reducing the emissions of trucks serving the Los Angeles seaport, through which more than ten thousand trucks pass per year.

In addition to the pilot batch of tractors, the construction of two hydrogen filling stations is also envisaged, which will initially serve the vehicles during their two-year test operation, and in the future will be able to become part of the California network of hydrogen filling stations.

Hydrogen tractors are capable of driving a distance of 60 kilometers on one tank of hydrogen (480 kg). Toyota and Kenworth are confident that hydrogen-powered trucks have good prospects, especially since in 2035 California will legally ban the operation of trucks with internal combustion engines. Which means a radical renewal of the fleet of freight carriers.

Currently, Toyota is one of the world leaders in the development of hydrogen vehicles and one of the few automakers who have a mass-produced hydrogen vehicle in their model range - the Toyota Mirai sedan.
