self propelled fluid

03.04.2017

At Brandeis University (Massachusetts), scientists have created a fluid that is capable of self-propelled. The movement of the liquid is set by animal cells dissolved in water, obtained from the brain of a cow.

The fluid self-propelling properties are achieved due to the lability and mimicry of microtubules contained in the animal's brain cells. The cylindrical elements isolated from the cell have the ability to contract, adapting to the environment. The dynamics of the movement of the tubes sets the movement of the general environment in which the elements of the cell from the brain of a mammal are placed, since due to the cylindrical shape of the tubes, their movement has a predictable motion vector.

The discovery is of practical importance, since the principle of operation of elements placed in a liquid can set the entire medium in motion according to specified parameters. In the field of oil transportation, this discovery promises to bring a significant economic effect, since it will allow abandoning gas pumping stations and units, the design of which does not correspond to the qualities of the oil being distilled, which has new properties.

The practical significance of the discovery will also be found in other industries where dynamic controlled properties of liquids are required. Use outside of laboratory conditions requires additional studies.

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 ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Bacteria produce fuel 25.03.2022

By studying the enzyme that bacteria use to catalyze this reaction, scientists have discovered key structures that control this process. True, experts do not yet know how to manage it.

Specialists from Northwestern University (Chicago, USA) were able to find bacteria that produce fuel. So, an experiment was conducted with methanotrophic microorganisms. They consume approximately 30 million metric tons of methane annually. In this way, bacteria turn greenhouse gases literally into diesel fuel.

Scientists still cannot understand how exactly this feature of bacteria can be used for the benefit of mankind. At the same time, while studying the enzyme with which bacteria catalyze this reaction, scientists have identified the main structures that control this process.

According to the researchers, meth has strong bonds, and therefore an enzyme that can break these bonds is a real discovery.
