Record for the longest stay of a woman in space

28.12.2019

American astronaut Christina Koch set a new record for the longest space flight for a woman, having spent more than 288 days on the International Space Station (ISS).

American astronaut Christina Koch has not yet completed her work on the ISS, but has already broken the record - for the duration of uninterrupted stay in space among women. The American spent 289 days on the space station - which is a day more than the previous record set by astronaut Peggy Whitson.

Koch arrived at the International Space Station on March 14. According to the NASA schedule, she will stay in space until February 2020 - and thus, will come close to the record for the stay of NASA astronauts on the ISS, which was set by Scott Kelly and is 340 days. Typically, astronauts stay on the ISS for six months.

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 ... >>

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, ... >>

Strawberries improve memory 07.11.2023

Regular consumption of strawberries has been shown to have positive effects on memory and mood among middle-aged people with mild cognitive impairment. The anti-inflammatory properties of anthocyanins in strawberries may reduce the risk of dementia in this age group.

One theory suggests that cognitive aging and the development of neurological diseases such as Alzheimer's disease are associated with inflammatory processes in the body, including the brain. Metabolic disorders and obesity enhance these processes, which may lead to an increased risk of dementia in people who are overweight and insulin resistant. Therefore, it is believed that reducing inflammation may reduce the likelihood of developing dementia and even help treat it.

Anti-inflammatory substances such as anthocyanins are often found in natural foods, including berries and strawberries, which University of Cincinnati scientists have found have the ability to cross the blood-brain barrier into the brain. From this point of view, the researchers decided to test whether regularly eating strawberries could affect cognitive function.

In the study, 30 participants aged 50 to 65 years, mostly overweight or obese women with mild memory impairment, took strawberry capsules equivalent to 130 grams of fresh berries or a placebo for 12 weeks. The results showed no improvements in metabolic measures associated with being overweight, nor in executive function, verbal memory, or spatial skills. However, the strawberry group showed a reduction in memory interference, a phenomenon where old memories interfere with the ability to recall new ones, especially in older age and dementia.

Additionally, participants in the strawberry group reported improved mood compared to those taking the placebo. These results suggest that strawberry supplementation may reduce the risk of dementia among middle-aged people.
