Pod peas for quantum computers

02.04.2002

A group of American and Korean physicists propose a new electronic component for the quantum computers of the future. They called their creation "peas in a pod".

This is an ultramicroscopic structure made of carbon: a tube with a diameter of several picometers (billionths of a millimeter) was stuffed with carbon balls - fullerenes. By moving the balls along the tube with the help of an electrostatic charge, one can smoothly change the electrical properties of this complex from an insulator to a semiconductor and then a conductor. In addition, by moving the balls, you can change the resonant properties of the tube (as the movements of the wings change the pitch of the trombone) for the flow of electrons through it, that is, control the frequency of the current.

Previously, the same group of scientists showed that from a single "pea" placed in a nanotube, you can make a trigger, the basis of any computer, which will work in 10 trillionths of a second - several orders of magnitude faster than modern computer chips. All these properties could make "peas in a pod" the basis of quantum computers in the near future.

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 ... >>

Statin on a bioconveyor 26.04.2015

Statins are substances that inhibit a key enzyme that produces so-called bad cholesterol. Accordingly, its content in the blood falls, and with it the risk of atherosclerosis. A natural statin called compactin is found in mushrooms and was isolated by Endo Akiro in the mid-70s from a mold. However, it is inconvenient for pharmacists.

In the 80s, another statin, lovastatin, was discovered. It was also found in higher fungi, such as oyster mushrooms. In order not to force the population to eat huge amounts of mushrooms, chemists have come up with methods for synthesizing statins, and many doctors consider this the most important public health achievement in the last twenty years.

Synthesis, however, is complex and expensive, it involves several steps and subsequent purification. Biotechnology from the University of Manchester and DSM's Delft Biotechnology Center, led by Christie McLean and Marco van den Berg, managed to do it all in one step.

To do this, they reprogrammed an industrial strain of the mold Penicillium chrysogenum that produces antibiotics. First, the gene responsible for the decomposition of compactin was removed from it. Then they inserted the genes necessary for the efficient synthesis of compactin. Then they forced him to synthesize also cytochrome P450 of the bacterium Amycolatopsis orientalis, this protein turns compactin into one of the most effective statins - pravastatin. But this transformation went very badly, because the result was a mixture of stereoisomers, which are very expensive to separate.

The properties of cytochrome were altered by artificial selection, and eventually a process was achieved that synthesized the purest stereoisomer of pravastatin at six grams per liter of culture. This can already be implemented in production.
