What creatures are responsible for the color of Bloody Falls in Antarctica?

In Antarctica, Blood Falls emerges from the Taylor Glacier from time to time. The water in it contains ferrous iron, which, when combined with atmospheric air, oxidizes and forms rust. This is what gives the waterfall its blood-red color. However, ferrous iron in water does not occur just like that - it is produced by bacteria living in a reservoir isolated from the outside world deep under the ice. These bacteria have managed to organize a life cycle in the complete absence of sunlight and oxygen. They process the remains of organic matter, and "breathe" ferric iron from the surrounding rocks.

What specific figure used to mean the word figure?

The word "digit" goes back to the Arabic "digit", which means "zero, empty". In most European languages, as in Russian, this word eventually began to denote any numerical character. Only in English one of the meanings of the word cipher is still "zero, fiction".

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, ... >>

Gaming platform for virtual games Virtuix Omni 15.04.2014

Virtuix Omni has announced the start of accepting pre-orders for its virtual reality platform. The project was previously spotted on the Kickstarter website, where it raised about $1,1 million, which exceeded expectations from fees by almost 10 times.

This device is a circular platform in which the user can control the movement and jumps of the game character, moving like on a treadmill.

The developers claim that their gaming platform in conjunction with the Oculus Rift virtual reality helmet will appeal to many gamers.

The Virtuix Omni platform pre-order price is $500. The price includes a special pair of shoes, straps for fixation, and equipment and software for tracking movements. Separately, it is noted that neither the Oculus Rift helmet nor the game controller are included in the package. Customers who pre-order now will receive the Virtuix Omni in September. Kickstarter fundraisers will be able to get the Virtuix Omni in July.
