Self-healing glass

15.12.2017

A group of Japanese researchers created a special glass that has the ability to self-heal if its integrity is violated. During the development of a new type of adhesive type, a material was created that can be easily restored after a breakdown.

Researchers at the University of Tokyo, in the course of their experiments to create a special adhesive agent, managed to make a material that resembles ordinary glass in all characteristics. The main feature of the created novelty is that if the parts of the glass formed from its breaking are applied to each other along the junction where the split occurred, then they will rejoin each other.

Scientists argue that the former strength of this material in case of violation of its integrity can be easily restored by holding the broken parts in contact with each other for several hours.

The scientists called this invention "polythiourea", and according to their assurances, the new material can soon replace the usual fragile glass, which is thrown away immediately after losing its integrity.

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 ... >>

Broccoli against blood clots 07.03.2024

The chemical sulforaphane found in broccoli has a beneficial effect on preventing blood clots. Unlike other blood clot medications, sulforaphane did not increase the risk of hemorrhage in mice. Scientists hope that this substance may be useful in the treatment and prevention of stroke.

The discovery of the beneficial effects of sulforaphane on the prevention of thrombosis opens up new prospects in the fight against fatal cardiovascular diseases. However, more research is required to understand the mechanism of action of the substance and its potential use in humans.

In the study, the researchers analyzed 23 chemical compounds commonly found in plant foods because many of them exhibit biological activity, including effects on blood clotting. In laboratory conditions similar to the environment found in arteries, sulforaphane was found to slow platelet aggregation, which may prevent the formation of blood clots that can cause a stroke or heart attack.

Scientists suggest that sulforaphane may be effective in both preventing stroke and reducing its consequences. Unlike the existing drug for treating the effects of stroke, which is effective in only a small proportion of patients, sulforaphane was effective in 60 percent of subjects in experiments on mice.

However, before introducing the drug into practice, it is necessary to conduct additional research to determine its effectiveness and safety for humans. It should also be studied whether a diet rich in broccoli would be beneficial for people at increased risk of blood clots.
