What tree bark can be painted in all shades of the rainbow?

On the islands of Southeast Asia, rainbow eucalyptus grows - a tree with multi-colored bark. In a young tree, the bark is bright green, but gradually its different parts ripen and turn into all shades of the rainbow.

What is the difference between edible mushrooms and grebes?

The answer is that there is no difference between them! Scientifically speaking, there is no such thing as "toadstool". Many people call poisonous mushrooms grebes. Botanists do not use this term at all, and for them there is no difference between an edible mushroom and what we call grebes.

There are many ideas about mushrooms, but they are completely wrong. There are very few types of mushrooms that are poisonous. But they are really deadly. Therefore, no one should eat or even taste mushrooms until he is sure that they are not poisonous. But people do not always correctly determine the toxicity of mushrooms. For example, it is not true that all umbrella-shaped mushrooms are poisonous.

It is also not true that mushrooms are poisonous if, when they are boiled, a silver spoon darkens with which they are interfered with. Poisonous mushrooms contain such a strong poison that eating them means certain death. There is a story that Emperor Nero once poisoned a whole group of guests by treating them to poisonous mushrooms. The best way to avoid this is to eat store-bought mushrooms.

Mushrooms are in the same family as molds. Like all plants belonging to this group, they lack the green substance, chlorophyll, without which the plant cannot produce food for itself. They grow next to some other plant that has chlorophyll and are completely dependent on it. Mushrooms are very delicate plants. They are made up mostly of water, so most of them can't stand dry winds or the hot summer sun.

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, ... >>

Living organism found without air 28.02.2020

Israeli scientists have discovered a multicellular living organism that does not need air to live. A parasite with the Latin name Henneguya salminicola, which was found in salmon, has become a unique animal.

Scientists were able to discover during the study that the parasite does not have a mitochondrial genome. That is, the air for him is not the basis of existence.

At the same time, it is noted that previously organisms were already known that could survive with a limited amount of oxygen, but this type of parasite is the first multicellular creature that can completely do without air.

The researchers speculate that mitochondria were lost by the Henneguya salminicola parasite during evolution as it needed to adapt to its environment.

According to scientists, such a discovery could change the understanding of life not only on Earth, but also in space.
