Which female animal can produce two types of breast milk at the same time?

Female wallabies, mammals of the kangaroo family, are capable of producing two types of breast milk at the same time. A recently born calf feeds from one nipple, and an older calf that has already left the pouch feeds from the other. Milk for him is more fat and with a different composition of nutrients.

How long ago was the Great Wall of China built and how big was it?

In 214 BC, the first Chinese emperor Qin Shi Huang ordered to connect the already existing earth embankments on the northwestern borders of the country with a solid clay wall - to protect against the attacks of nomadic peoples.

This is how the Great Wall of China was born. Subsequently, it was repeatedly completed and repaired.

The total length of this outstanding monument of antiquity reached 7200 kilometers, the height was 6,6 meters (in some areas up to 10 meters), the width of the lower part was about 6,5 meters, the upper part was about 5,5 meters. Throughout the Great Wall of China, casemates for protection and watchtowers were built, and fortresses were built at the main mountain passes.

Much of the Great Wall of China has survived to this day.

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, ... >>

Copper for hospital 09.11.2008

A curious experiment has been going on in one of the hospitals in Birmingham (Great Britain) for almost a year. They took two intensive care units and in one replaced with copper, brass or bronze all the steel, aluminum and plastic parts that doctors, nurses and patients touch: door and window handles, water taps, switches, buttons and so on. In another similar department, everything was left as it was and microflora samples are regularly taken from all these details.

The results of the experience have not yet been summed up, but preliminary studies conducted at the University of Southampton show that copper and its alloys have bactericidal properties. Copper prevents bacteria from breathing and damages their DNA, although the mechanism of this action is not yet clear. In any case, 10 million Staphylococcus aureus placed on a square centimeter of a copper plate (which is 10 thousand times more than the number of these microbes on the same area of a door handle in a hospital) die in an hour and a half.

Although this staphylococcus tolerates antibiotics without any harm to itself. Copper also kills Clostridium, a dangerous microorganism that is not even amenable to alcohol-based disinfection solutions that surgeons wash their hands with.
