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 ... >>

Skin bacteria on guard of our health 14.11.2016

Modern medicine is increasingly finding out that we have been fighting any bacteria on our body in vain for so long. For example, the bacteria found in patients with severe acne can be very beneficial to our health.

One of the most common bacteria on our skin, called Propionibacterium acnes (so called because it was first found in a person with very severe acne, although it is still unknown if it is the cause of it) secretes a RoxP protein, which protects against oxidative stress, that is, the process in which the body receives damage due to oxidative reactions that are not characteristic of it. The most common cause of oxidative stress is solar radiation.

"This protein is essential for the very survival of the bacterium on our skin. The bacterium improves its habitat by releasing RoxP, but by doing so, it also benefits humans," says Rolf Lud, the scientist who made the discovery.

Oxidative stress is considered one of the causes of many skin diseases, including atopic dermatitis, psoriasis, and skin cancer. Since Propionibacterium acnes is extremely common, it lives on the skin of both sick and healthy people, but, according to Luda's research, different people have different levels of bacteria on the skin and, accordingly, the level of protective protein too.

That is what Lud's group is doing now. They study people with basal cell carcinoma and a precancerous condition called actinic keratosis with a healthy control group. The study will show if there is definitely any link between RoxP levels and skin disease. If the assumption is confirmed, then it will give impetus to new drugs based on the discovered protein or even symbiotic agents with bacteria.
