Which birds supply the material for swallow's nest soup?

The famous Chinese soup "swallow's nests" is actually prepared from the nests of salangans - birds of the swift family, which build them from their own hardening saliva.

Who first reached the South Pole?

Roald Amundsen, a Norwegian polar explorer, was the first to reach the South Pole by hoisting the Norwegian flag on December 14, 1911.

On January 17, 1912, an English expedition led by Robert Falcon Scott arrived at the Pole - to their greatest disappointment, to see the flag hoisted by Amundsen.

The expeditions reached the Pole by various routes and were equipped differently. Amundsen took the shorter route. Along the way, he set up camps with enough provisions for the return. As a vehicle, he used a sleigh drawn by Eskimo dogs, accustomed to extreme climatic conditions.

Unlike the Norwegians, the British went to the Pole on a motor sled, and the dogs were taken only in case the sled failed. The sleigh quickly broke down, and there were too few dogs. The polar explorers were forced to leave part of the cargo and harness themselves to the sled. The track Scott walked along was 150 kilometers longer than Amundsen's. On the way back, Scott and his companions died.

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, ... >>

Basis for ReRAM memory chips with a density of 100 Gbit 28.06.2017

Sony Semiconductor Solutions talked about developments related to ReRAM memory, which combines the advantages of DRAM and NAND.

Key technologies developed by Sony specialists will enable the production of high-density ReRAM memory chips.

The memory, created by Sony Semiconductor Solutions, uses copper ions. The cell design includes only one sample element and one resistive element (1S1R structure). This makes it possible to manufacture memory in the form of a simple matrix of intersecting lines and arrange such matrices in several layers, increasing the density.

One of the new developments is a barrier between the ion reservoir and the electrolyte, which reduces the uneven resistance. Due to it, it is possible to increase the storage density.

The second technology is the doping of the sampling element with boron and carbon, due to which the leakage current is reduced and the resource is increased.

According to Sony Semiconductor Solutions, the developed technologies will make it possible to produce ReRAM memory with a write time of 100 ns, a resource of 10 million cycles and a density of about 100 Gbps.

ReRAM is expected to fill the gap between DRAM and NAND in terms of cost, performance and integration.
