Can a tree communicate what it needs?

Scientists have found that the tree "screams" in the range of 50-500 kHz when it begins to dry out. This "plea for water" is not audible to the human ear, but for bark beetles it serves as a signal: to finish off a dying tree.

Why does the body need water?

Approximately 60 percent of the human body is water! If you squeeze a person like a lemon, you can get about 50 liters of water. This water, which differs from ordinary water in the presence of various substances, is necessary for the life of the body. Approximately a gallon (about 4,5 liters) of this water is contained in the blood vessels, and a constant blood circulation is maintained by the work of the heart.

The water present in the blood washes all the cells of the body with a direct current. Water also serves as a conductor of heat throughout the body. Even if you do not drink water during the day, you will still get about a liter of liquid from the solid food you eat. Therefore, when you eat fruits, vegetables, bread and meat, you get water, since 30-90 percent of these foods are water.

In addition, each person on average drinks about two liters of water in the form of various drinks. During the day, approximately ten quarts (1 quart - about 1 liter) of water circulates between the various organs in the body. For example, when you chew and swallow something, you also swallow some of the saliva coming from the salivary glands. After a short time, this water is replaced in the glands by water from the blood vessels. And the swallowed water subsequently enters the blood from the stomach and intestines.

The amount of water in the blood always remains constant. Even when you feel completely "dry" after exercising in hot weather, your blood vessels still contain the same amount of water. And no matter how much liquid you drink, this amount remains the same.

What happens to excess water? It accumulates in different parts of the body: in the intestines, liver, muscles and kidneys.

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, ... >>

Creation of an artificial uterus 27.08.2016

The first 13 days after human conception are still largely a mystery to scientists, as the process is almost impossible to observe. But now scientists have created the world's first artificial womb, or at least a prototype.

We cannot look into the uterus, we cannot see how fertilized eggs grow, so we understand the whole process only in general terms. However, researchers at the Rockefeller Center were the first to be able to observe and grow human embryos for 13 days in a fully laboratory environment (more observation of egg growth is prohibited by law for ethical reasons). Scientists raised the embryos with insulin and other nutrients outside of the usual conditions. The experiment demonstrated that the embryo itself contains a set of genetic instructions responsible for development, which is not associated with the mother (at least at the initial stage)

This research provides an opportunity to develop new models of human growth, and may also help in cases of miscarriage and infertility. Of course, this does not mean that in the future all children will be raised in a laboratory, but it is quite possible that the human uterus will be just one of the options.
