Who are the parasites?

Sometimes you can hear from people that they don't want to live like parasites. They want to do everything themselves. Parasites live inside or outside other organisms - the so-called "hosts". All living beings live independently. But parasites live at the expense of other organisms. Parasites take everything from the "owner", but do not give him anything in return! Both plants and animals can be parasites. They can live either on plants or on animals. Sometimes parasites live with different kinds of "hosts", but usually they can coexist with one kind of "host".

Sometimes parasites suck out all the juices from the "master", secrete toxic substances and thereby kill him. Almost all forms of parasites are very prolific and hardy. If it were not so, they could be completely exterminated! Let's look at some parasites. The smallest of them are bacteria. Bacteria are known to cause disease in animals and plants, as well as in humans.

Next in development are fungal parasites. Ringworm in humans is caused by one of these plant parasites. Other types can cause rust, mold and plant wilt. There are a large number of parasites in the animal kingdom. Here also the smallest parasite is one of the most significant. There is such a microscopic single-celled animal - the protozoa. These parasites cause African sleeping sickness, malaria and other diseases in humans.

Some types of worms are the next group of parasitic animals. Roundworm - trichina - the cause of the disease of pigs and humans with trichinosis. Parasites are also worms and flatworms. The highest form of parasites that settle on the skin are fleas, ticks and lice.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Nubia Red Magic 3 is a smartphone with a fan 03.05.2019

Compact active cooling systems have come to smartphones: the concept of such a device with four coolers is presented by Nubia. A year later, a serial gadget with this technology enters the market - the Nubia Red Magic 3 gaming smartphone.

The Red Magic 3 is powered by Snapdragon 855, has a 90Hz AMOLED screen and a 5000mAh battery. The highlight of the smartphone is an active cooling system with a single fan. The weight of the impeller is about one gram, the maximum rotation speed is 14 thousand revolutions per minute, and the hydrodynamic bearing gives stability and reliability to the whole structure.

According to the manufacturer, the cooler operates almost silently and is not afraid of moisture or dust - certification of protection against external influences complies with the IP55 standard. The brushless electric motor consumes no more than 1% of the battery charge per hour of continuous operation. A lot of attention has been paid to the autonomy of work: thanks to the energy-efficient screen and cooling system, the game time on a single charge is 8,5 hours.

The camera in the new smartphone of the Chinese brand is one, based on the Sony IMX586 sensor with a resolution of 48 megapixels. The screen has a diagonal of 6,6 inches, has pronounced frames at the top and bottom, and on the right side of the device there are two additional keys. Four variants of the Nubia Red Magic 3 have been announced, differing primarily in the amount of RAM and permanent memory, the most expensive of which with 12 GB of RAM and 256 GB of a flash drive will cost about $640.
