In which fish do males parasitize females?

In some families of deep-sea anglerfish, males parasitize females. The male bites into the female with his teeth, and then grows together with her lips and tongue, as well as the circulatory system. The rest of the male's body turns into an appendage that produces sperm. Moreover, up to three males can parasitize on one female at the same time.

What is typhoid fever?

Some of the most serious illnesses are gradually disappearing because people keep themselves clean and follow generally accepted sanitary standards. One such disease is typhoid fever. Just 60 years ago, thousands and thousands of people died every year from it.

Now death from typhus is almost excluded, but still occurs in the most backward regions. The causative agent of typhoid fever is Salmonella tiffosi, which belongs to the family of intestinal bacteria. She settles in the products of excretion.

After entering the human body, bacteria can constantly be in it, but do not multiply. Some people who have been ill with this disease become chronic bacteria carriers. Their body has such a feature that, in the absence of signs of the disease, it constantly contains the causative agent of this disease.

Once having been ill with typhoid fever, a person acquires strong immunity for life. Infection can occur when bathing in polluted water bodies, when drinking poor-quality drinking water, especially when there are violations in the water supply and sewerage system. You can also get infected both by direct contact with the patient, and through the things that he used.

There is a possibility of infection through food. When a person falls ill with typhus, he begins to feel general weakness, insomnia and sweating appear. In some patients, already at the very beginning of the disease, there is stupor, hallucinations and delirium. Within one to two weeks, the high temperature persists, then it begins to subside. After 30 days, the temperature returns to normal. During illness, a rash appears on the body. Usually on the skin of the abdomen, less often on the chest and shoulders.

Now the occurrence of typhus is prevented by sanitary requirements for water and sewerage. In addition, bacteria carriers should not take food with their hands. There is a typhoid vaccine that lasts for at least a year. There is one that has been around for several years.

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, ... >>

Free Wi-Fi has become more important than sex and alcohol 16.11.2016

Mobile workers (workers who work remotely for their companies or are often on the road) believe that free Wi-Fi is more important than chocolate, alcohol, and even sex. This is evidenced by the results of a study by the global Wi-Fi provider iPass.

40% of the mobile workers surveyed said that free Wi-Fi is the number one thing they need every day. At the same time, 37% of respondents believe that it is more important than sex, 14% - that it is more important than chocolate, and 9% put Wi-Fi above alcohol.

75% of survey participants said that free Wi-Fi significantly improves their quality of life. 63% of respondents reported that they prefer it to mobile data. When choosing a package of mobile services, 75% of respondents look primarily at the conditions of data transfer, and not at the minutes of calls.
