Fat taste receptors discovered

08.09.2020

American scientists have proven for the first time that the human tongue perceives the taste of fat. What's more, they found that variations in a gene called CD36 make people more or less sensitive to fat. This may explain why some of us gain weight while others do not.

Traditionally, there are five main tastes - sweet, salty, sour, bitter, and umami. The first four tastes are typical for European culture, and the last one is for Asian. Umami is a taste sensation produced by fermented and aged foods such as soy sauce and fish sauce. For each taste, a certain area of \uXNUMXb\uXNUMXbthe tongue is responsible. In particular, we perceive the sweet with its tip. With regard to fat, scientists were of the opinion that people feel its texture, not taste.

American researchers have refuted this claim. Participants in the experiment were offered three cups, one of which contained a solution with a small amount of fatty acids. The other two were filled with a liquid similar in texture but without added fat. People had to choose a cup, the contents of which differed in taste from the rest. They succeeded, despite the fact that, according to the conditions of the experiment, they could not assess the appearance and smell of the solution. This suggests that there are taste buds responsible for the perception of fat. But where they are located in the language is still unknown.

Some of the participants in the experiment were carriers of a gene that causes reduced production of the CD36 protein. It turned out that such people are 8 times less sensitive to the taste of fat. Scientists believe that the number of CD36 is affected not only by genes, but also by diet. In people who eat a lot of fatty foods, protein production gradually decreases. As a result, a person needs to eat even more fatty foods in order to get the same pleasure as before. This vicious cycle leads to weight gain.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

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 ... >>

Named the most attractive type of woman 07.01.2018

Men more often prefer blondes than brunettes or brown-haired women. As a result of a large-scale study, specialists from the University of Augsburg in Minnesota (USA) came to this conclusion.

The researchers showed 110 male volunteers photographs of women with blonde, dark, and black hair turned back to the lens. After reviewing the pictures, most men considered younger blondes to be more attractive.

Scientists explain this choice by the fact that with age, hair often darkens, and lighter ones look younger.

Along with this, the majority of men admitted that they would rather choose a woman with dark hair or a brown-haired woman for marriage and creating a family. This time, the subjects explained their choice by the fact that they consider blondes to be somewhat frivolous.
