Why are rhinoceros horns sawed off under anesthesia in the countries where rhinos live?
The horn of a rhinoceros cannot be called a horn in the strict sense of the word: unlike, for example, a bull's horn, it does not contain bone tissue, but consists of glued bristle-like hair. Due to the fact that these horns are highly valued in oriental medicine, rhinos are currently under the threat of extinction. To protect against poachers, the authorities of some countries where rhino populations live, catch animals and saw off the horn under anesthesia.

Random interesting fact from the Great Encyclopedia:
What kind of fish lay their eggs for rearing other fish, like cuckoos?
There are several types of fish that hatch fertilized eggs in their mouths. The fish Synodontis multipunctata, or cuckoo catfish, has learned to parasitize on this mechanism. Feeling the smell when its victims spawn, this catfish quickly swims up to them, eats part of the eggs and immediately spawns its own, and then the "foster mother" takes them into her mouth. Moreover, cuckoo catfish fry hatch earlier and eat the remaining native eggs.

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, ... >>
