Are rats pests?

In the entire history of mankind, there was no such animal that people would not fight everywhere with greater fury and zeal than with rats! And while most rat species are completely harmless and interesting animals, the two most common varieties of rats - brown and black - have managed to create a disgusting reputation for the entire family. So why do people fight rats?

The fact is that every year these animals destroy millions of tons of valuable grain, eat eggs, domestic and songbirds, spoil food in houses and on ships. A lot of fires happened due to rats gnawed wicks, gas pipes, electrical wiring insulation, and water pipes damaged by rats caused flooding in houses. In addition, rats spoil floors and furniture, and, finally, they spread diseases, including, fortunately, bubonic plague, which is rare in our time.

The number of rats in the cities, apparently, is not inferior to the number of people, and in the villages there are actually 3-4 rats for each person! They can climb walls and burrow into the ground, live indoors and outdoors, in dry and wet places. While generally preferring vegetables, rats will eat everything. And since these animals can live anywhere and reproduce very quickly, they are very difficult to control. A female rat can give birth to up to 10 cubs a year, and those, in turn, are ready to bring their own offspring after 4 months!

The homeland of black rats is the peninsula of Asia Minor and some countries of the East. These rats came to Europe with the crusaders returning from Palestine. Brown rats originally lived in the barren steppes of Central Asia and probably began their mass migration shortly before the time of the Roman Empire. Like black rats, they have found their way to all parts of the world in the holds of ships and have shown themselves to be one of the most adaptable animals. Just like mice - another rodent that lives with people - rats have become very popular pets and are specially bred for this purpose. Of course, ordinary wild rats are never used for breeding domestic rats, although they are relatives to each other in color and some habits.

White rats are actually albinos of brown rats. An albino is an animal that has impaired pigmentation of the skin and coat. Such individuals are rare, but humans specifically breed albinos because of their color. Pet rats are best kept in cages, but the living space should be large. It is recommended to make cells with a slope leading to the second "floor". And, of course, it is better to use iron cages, because the wooden bars can be gnawed when the rats get bored with this dwelling.

Domestic rats are very unpretentious, and the best food for them is ground or crushed oatmeal mixed with bird food. The lifespan of domestic rats is two to three years.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Sentinels for the seas 12.08.2006

The European Union has allocated 45 million euros to set up a tsunami warning system off the coast of Southeast Asia.

Buoys developed at the Geophysical Center in Potsdam (Germany) should become the basis of the system. They will be deployed in the Indian Ocean. Each of them has three sensors that register the approach of a tsunami in different ways. At the bottom, under the buoy, a seismograph is installed that notes the shaking of the seabed, and a pressure sensor that reacts to the passage of a tsunami wave over this section.

A system is mounted on the buoy itself, which, using navigation satellites, marks the rise of the buoy by a tsunami wave (this wave is wider than ordinary storm waves and causes a prolonged rise in the water level, so that it can be distinguished from ordinary waves). These sentinel seas will report signs of an impending disaster to a center under construction in Jakarta (Indonesia).

The only question now is how reliable the data transmission channel from the bottom to the buoy will work - the designers intend to use ultrasound propagating through the water, since the cable may be twisted or torn.
