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 ... >>

Premium electric car Mercedes-Benz EQS 20.04.2021

Mercedes-Benz has introduced the Mercedes-Benz EQS premium sedan. The model was the brand's first electric vehicle built on the new Daimler platform, aimed at upper-class models. The EQS 450+ and EQS 580 4MATIC configurations will be the first to enter the market, with other configurations to follow in the future.

The designers of the novelty have retained the recognizable features of the related S-Class, but at the same time they have focused on the electric nature of the EQS, having designed the body in the form of a single extended arc with a cabin moved forward and a roof smoothly lowering towards the rear. As a result, it was possible to achieve a reduction in the level of aerodynamic resistance to a record mark for production cars of 0,20.

The rear-wheel drive version of the Mercedes-Benz EQS 450+ received an eATS electric motor on the rear axle with a power of 245 kW and a torque of 568 Nm, which allows this large (5216x1926x1512 mm) sedan to accelerate to 100 km/h in 6,2 seconds. In turn, the all-wheel drive EQS 580 4MATIC with two eATS electric motors on each axle provides a total power of 385 kW, a torque of 855 Nm and acceleration to “hundreds” in just 4,3 seconds. The top speed of both versions is limited to 210 km/h for safety reasons.

Both versions of the electric vehicle use the same 107,8 kWh battery, which provides a WLTP range of up to 770 km. A little later, the Germans promise to introduce more affordable versions of the model with a 90 kWh battery. The electric vehicle supports 11kW mains charging (22kW optional) and DC fast charging up to 200kW. In the first case, the time for a full charge will take 10 hours (5 hours optional), in the second - 31 minutes to a full charge, or about 300 km from a shorter 15 minute charge. In Japan, customers will also be provided with a two-way charging function.
