Cosmetics 2000 years old

10.12.2003

During excavations in the London district of Southwark, a sensational find was made: in the ruins of a Roman temple, archaeologists discovered a round tin box. When it was opened, there was an oily white substance inside, and a sulphurous-cheesy smell hit the nose.

Scientists have found nothing but an ancient Roman cosmetic cream. He is about 2000 years old, but he looks like the hostess opened the box just yesterday. On the surface, even traces of a finger that scooped up a fraction of the cream are visible.

This is the first time that such ancient cosmetics have been discovered in such a state of preservation. Archaeologists are now awaiting the results of a chemical analysis of the cream.

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 ... >>

Wi-Fi for pregnant women 23.07.2015

According to popular belief, radiation from Wi-Fi devices can have a negative impact on the human body. The Chinese company Qihoo has made an attempt to neutralize possible threats with the help of a new "pregnancy mode", which can reduce the intensity of radiation by 70%. The target audience for the innovation, Qihoo CEO Zhou Huni, called pregnant women and, in general, everyone who fears for their health.

Xiaomi, another Chinese tech giant, reacted to competitors' actions by posting an accusatory post on Weibo: "The so-called 'pregnancy mode' is just a publicity stunt. Using Wi-Fi is safe, you can be sure of it."

The World Health Organization also did not confirm Qihoo's concerns about the health of mothers and their unborn children. A report posted on the WHO website states that, according to recent studies, exposure to low-frequency electromagnetic waves does not carry the risk of possible miscarriages, pregnancy complications and the occurrence of various diseases in newborns.

The debate about the safe use of Wi-Fi has not subsided since 2011 after large-scale studies were carried out to study the effect of technology on the cells of a living organism. For example, it has been proven that if Wi-Fi is working in the immediate vicinity of a man during the exposure of the ejaculate, the mobility of his spermatozoa will decrease by 20%, and damage to their DNA will increase by 2,5 times. Before that, it was argued that Wi-Fi does not cause any harm to human health.
