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 ... >>

Record Density DDR5 Chips 24Gbps 19.12.2021

South Korean memory chip manufacturer SK Hynix announced the successful development of DDR5 DRAM chips with an industry-leading 24Gb chip density.

SK Hynix released the first DDR5 DRAM chip with a density of 16 Gb in October 2020. And now the South Korean manufacturer is increasing the density to 24 Gb (the DDR5 standard provides for a peak density of 64 Gb).

The new memory is based on improved 1anm technology using hard ultraviolet (EUV) lithography. Manufacturer claims up to 33% higher yield and speed with 25% lower energy consumption than current products

The new chips will form the basis of future 5 and 48 GB DDR96 modules, which will first find use in data centers, and then probably get to consumer PCs.

SK Hynix has already shipped the first samples of the new memory to customers, and large-scale shipments will begin next year. In a press release, among the partners, Intel is indicated, which is preparing to release 4th generation Xeon Scalable server processors (Sapphire Rapids) with DDR5 and PCIe 5.0 - they will be based on the current Golden Cove architecture (Core 12th generation).
