Where do the coins from the Roman Trevi Fountain go?

Coins, which, according to an old belief, tourists throw into the Trevi Fountain in Rome with the hope of returning to the Eternal City again, are extracted from there once a week using a machine that most of all resembles a huge vacuum cleaner. Up to half a million dollars are collected per year, so the fountain cleaning work pays off well.

Random interesting fact from the Great Encyclopedia:

Can a mockingbird scream with its own voice?

Most people believe that because of its name and remarkable ability to imitate the songs and calls of other birds, the mockingbird is incapable of anything else. The imitative abilities of this creature are amazing. A case was noted when one observer heard how within 10 minutes a mockingbird reproduced the trills of 32 different birds! The mockingbird can even improve the songs of other birds by adding its own trills and overflows.

Did you know that the mockingbird sometimes even tries to imitate the sounds it hears near the farm - the clucking of a chicken, the barking of a dog, the creak of a wheelbarrow, or the sound of a postman's whistle? This, however, does not mean that this intelligent bird does not have its own distinct song. And she sounds very nice. The singing of the mockingbird pleases the ear in the US South, where this bird is found by the thousands. From time to time he sings in the winter. Around the beginning of March, he sings during the day and quite often on moonlit nights. He seems to be proud of his ability to sing.

Quite often it seems that one bird is trying to outsing another! But not only this makes people love the mockingbird. The bird is sociable and trusting by nature, and it may seem that she wants to live next to a person.

Occasionally, the mockingbird nests in bushes or vines around the entrance to a house. At other times, it builds nests on the corner of a fence, in bushes, thickets, or other familiar places. The nest is made from ropes, shreds, bark, feathers - in a word, from everything that comes across. It is tightly folded and lined on the inside. And when the eggs hatch, the mockingbird is ready to fight to protect them. He can attack birds twice his size, cats, dogs, and even humans.

Truly, this is a creature that is ready to die if necessary in order to protect its home and family! While the mockingbird prefers the South, it occasionally makes its way to northern states such as Maine. In summer, it can be found along the entire coast of the Gulf of Mexico.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

There is no star formation at the center of the Milky Way 12.08.2016

Astronomers from Japan, South Africa and Italy have discovered that there are no young stars in the vast region around the center of our galaxy. This unexpected result may lead to a revision of views on the evolution of the Milky Way.

Scientists have been looking in the inner region of the Milky Way for classical Cepheids, which are young stars with an age of 10 to 300 million years. (Recall that our Sun is about 4,6 billion years old.) This is quite a challenge, because the Galaxy is full of interstellar dust, which prevents many stars from being seen and affects the apparent luminosity of those that are visible. The researchers compensated for this with near-infrared observations. They worked at the Japanese-South African telescope in Sutherland (South Africa), a place known for having the cleanest and darkest nights in the world.

Astronomers have discovered almost 30 Cepheids and were surprised to find that there is not a single one within an 8000 light-year radius around the center of the Galaxy. The exception is a small region in the very center of the Galaxy with a radius of 150 light years, where four Cepheids were discovered even earlier. If there are no young stars in this vast region of the inner disk of the Galaxy, then there has been no significant star formation there for hundreds of millions of years. For comparison, the diameter of our Galaxy is about 100 light years, and the Sun is located at a distance of 000 light years from its center.

This result is consistent with recent studies by radio astronomers, but contradicts one work with similar measurements. However, the authors of this study believe that there was an error in determining the distance due to reddening of the radiation when passing through interstellar dust.
