Why do boa constrictors die?

Boa constrictor victims die not from suffocation, but from cardiac and circulatory arrest. The "embrace" of the snake causes a sharp drop in blood pressure, which stops the blood from delivering oxygen to the cells, as well as an increase in venous pressure, preventing the return of blood from the veins to the heart. Thus, the victim experiences a kind of heart attack, and the boa constrictor loosens its grip when it feels the heartbeat stop.

How did the Protestant religion come about?

At the beginning of the XNUMXth century, a religious revolution began, called the "Reformation". As a result, many branches of the Protestant religion emerged. Both words - Reformation and Protestantism - mean that the main thing in these religious revolutions was a passionate desire for change, which then happened in the Catholic Church. What did these people want to change and why?

One of the reasons for the protest is the way of life of many church hierarchs. They saw that for the clergy material concerns were more important than spiritual life. In addition, the reformers opposed the sale of indulgences - official documents that freed people from punishment for their sins. Many also envied the vast landholdings of the monasteries, although there were other forces that promoted the Reformation. Many people joined the reformers, mostly for political and economic reasons. Nationalism grew, and in its wake appeared the desire for a national church.

Another reason was that the power of the pope at that time was in question, since it affected not only church affairs. Great disagreements arose when the Holinesses began to share power with each other. In 1517, the sale of indulgences by unscrupulous merchants reached such proportions that it provoked a protest from the German scholar Martin Luther, an adherent of the Order of St. Augustine. He was excommunicated, declared a heretic, but his doctrines spread.

In 1530 he published the so-called Augsburg Confession containing 21 articles of the Protestant faith. The result is a complete rift between Catholics and Lutherans. The dogmas of the Reformation on which the Protestant Church is based have been adopted in various forms in other countries.

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, ... >>

Electronics rules the genes 17.11.2014

Swiss biotechnologists have developed a new method of regulating genes, which allows you to control the transformation of the latter into proteins (gene expression) using electromagnetic waves emitted by the brain.

“For the first time, we were able to record the waves that the brain emits with specific thoughts, transmit wirelessly to genes, and regulate gene expression with the power of thought. We have dreamed of implementing this project for more than ten years,” said Martin Fussenegger, professor at the Swiss Federal Institute of Technology Zurich ( Martin Fussenegger).

Scientists were inspired by the Mindflex game: a sensor on a special hoop captures electromagnetic waves emitted by the brain. Depending on the frequency of the waves, the toy increases the airflow that keeps the foam ball from falling. Thus, after a little training, a person will be able to control the ball with the power of thought.

The researchers took a similar electroencephalographic helmet. The electromagnetic brain waves are recorded and transmitted via Bluetooth to a controller that controls the excitation generator. This device creates an electromagnetic field that provides an induction current to a special implant. After that, the LED lamp lights up in the latter. Radiating in the near infrared range, it illuminates the culture chamber, which contains genetically modified cells. Reacting to light, they begin to produce the necessary protein.

The device was tested in mice: the model protein SEAP was excreted from the chamber into the circulatory system of mammals. Volunteer operators were divided into three groups, depending on the type of activity. With complete relaxation (meditation with closed eyes), the protein was produced in large quantities, with concentration of attention (the operators played Minecraft) - in medium. And in the presence of feedback (when people watched the light bulb and learned to consciously turn it on and off), the level of SEAP in the blood of mice constantly changed.

Scientists note the simplicity, efficiency and harmlessness of the system (radiation in the near infrared range does not harm the tissues of the human body). Fussenegger hopes that such implants will be useful in the fight against neurological diseases - chronic headaches, epilepsy, pain in the spine. The devices will detect the waves characteristic of these disorders and respond to them by releasing the right substances.
