The first colonizers of Mars will be frozen

07.11.2018

Scientists who are working on the issue of sending people to colonize Mars suggest that representatives of the first mission will have to be frozen before the flight.

Experts suggest that the best solution would be to introduce a person into a state of hibernation. In particular, such a prospect is stated by the representative of the University of Wisconsin Matthew Regan. Literally, future "Martians" will be frozen. This will allow scientists to slow down metabolic processes in human organisms. Thus, the amount of food and drink that will be taken on board the vessel will also be significantly reduced.

Matthew Regan considers this method to be the most effective. It will protect astronauts from harmful radiation in space.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Graphene will improve HDD 24.06.2021

Scientists at the Cambridge Graphene Center have shown that graphene can be used to create ultra-high-density hard drives, providing a tenfold leap over current technology.

Hard drives, which have been widely used in personal computers since the mid-1980s, have become smaller in this time, but significantly more capacious. Although they are being squeezed out by SSDs, HDDs are still popular due to their lower cost.

The increase in volumes is due to the increase in recording density, which in turn is provided by the improvement of two key components: platters and heads. In particular, developments that made it possible to reduce the gap between them.

At present, a significant part of this gap is occupied by carbon-based coatings - layers designed to protect the plate from mechanical damage and corrosion. Since 1990, recording density has quadrupled and coating thickness has decreased from 12,5 nm to about 3 nm. These parameters correspond to a density of 1 terabyte per square inch.

The Cambridge researchers replaced current coatings with graphene (from one to four layers) and tested friction, wear, corrosion, thermal stability and lubricant compatibility. It turned out that, in addition to its unrivaled thinness, graphene has all the ideal properties of the external coating for hard drives in terms of corrosion protection, low friction, wear resistance, hardness, compatibility with lubricants and surface smoothness. It reduces friction by half and provides better protection against corrosion and wear than current solutions. In fact, one layer of graphene reduces corrosion by 2,5 times.

The team also tested locally heated media recording (HAMR), a new technology that can increase storage density. Unlike graphene, the coatings currently in use do not operate at the temperatures required for HAMR. As stated, graphene in combination with HAMR will increase the recording density to an unprecedented level - more than 10 terabytes per square inch.
