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 ... >>

1 nanometer transistors 28.11.2014

Researchers at the University of Glasgow in the UK and the University of Rovira and Virgilli in Spain have been able to turn individual molecules into transistors to store information.

Today, flash memory is used in almost every mobile device. Manufacturers are striving to meet the increasing demands of users for its volume. But soon they will face a limitation on the size of transistors, which cannot be less than 10 nm.

The essence of the new method is to create a cell from tungsten oxide molecules with a side length of about 1 nm. Inside this structure are placed two molecules of selenium trioxide, which in the normal state carry additional electrons and thus have a negative charge. By applying voltage with different polarity, the researchers were able to change the charge of the structure, in other words, its binary state.

The given state of the structure in laboratory conditions was maintained for at least 336 hours (that is, 14 days), which allowed the researchers to speak of the new memory as non-volatile.

"Using individual molecules will allow us to continue to scale down the process and, in theory, even overcome Moore's Law by learning to store multiple bits of data in a single molecule," project leader Lee Cronin, a professor at the University of Glasgow, told Wired.

Moore's Law was shaped by Intel co-founder Gordon Moore. It states that the number of transistors on a chip doubles approximately every two years. Recently, however, scientists have begun to say that as the limiting size of transistors is reached, this law will cease to work. Various research groups around the world are looking for ways to make the law work further.

Meanwhile, some tasks before the creators of molecular memory still remain unresolved. This, in particular, concerns the speed of this type of memory. For example, it takes about 0,1 s to form the structure state, and 0,01 s to read the structure state. Both indicators are too high to speak of an effective commercial application.
