Skin care for astronauts

10.09.2023

Japanese companies POLA and ANA Holdings have developed a new line of cosmetics called Cosmology, specifically designed to care for the skin of astronauts in outer space.

These cosmetic products were created in response to a request from the Japan Aerospace Exploration Agency (JAXA) to develop skin care products in the resource-limited, low-gravity, dry air environment of spacecraft. Astronauts in space often face problems such as dry, itchy, sensitive skin and discomfort.

Development of the Cosmology line began in 2020, and JAXA agreed to manufacture these products in March 2022.

One of the unique features of these products is their economical use of water: the foam cleanser can simply be wiped off, while the lotion remains in a semi-solid state so as not to spill in low gravity conditions.

The products have been tested by flight attendants on ANA aircraft as flight conditions are similar to those on the International Space Station (ISS).

The Cosmology Space Crew Kit, which includes miniature cleanser and lotion, will be available from October 2023, with regular-sized products available in January 2024.

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, ... >>

Metal cracks can heal 27.10.2013

Scientists at the Massachusetts Institute of Technology (MIT) have made an unexpected discovery: under certain conditions, a metal can "heal" itself by closing cracks. This discovery could lead to the creation of self-healing materials that can work in the toughest conditions.

The discovery of scientists from MIT has great potential. As it turned out, in some cases, the forces that create cracks do not expand them, but rather "heal", restoring the integrity of the metal. Researchers are confident that it will be possible to create metals that, when cracked, will be able to self-repair and thus maintain structural strength even in the most difficult conditions. Such metals can be used in a wide range of applications, such as turbine blades and drilling tools.

The secret of the metal's unusual property lies in the interaction at the boundaries of tiny crystalline grains of the metal, the size and orientation of which affects the strength and other characteristics of the metal.

During experiments with nickel, which is the basis for high-temperature alloys, it was found that under certain conditions, the grain boundaries migrate and allow the metal to self-heal.

The very idea of grain boundary migration within a solid metal has been studied over the past decade. The phenomenon of self-healing in the course of these studies could not be detected because it is observed only with a certain migration of boundaries, the so-called disclination, when changes affect the grain only partially. During disclination, defects in the metal have such intense stress fields that the edges of the cracks do not diverge, but, on the contrary, approach each other, literally "melting" the broken metal.

The scientists plan to study in detail the metal's self-healing mechanism in order to design metal alloys capable of sealing cracks that are common in various operating conditions.
