The oldest denture was found in France. It dates back to the II-I century BC and is a metal pin. The prosthesis was inserted into the upper jaw of a man who died at about the age of thirty. And the prosthesis was inserted to him at least a year before his death. Judging by the research of French scientists, the metal from which the prosthesis was made bears traces of forging. It was inserted into the remains of a tooth, and this was done, judging by the reviews of modern dentists, quite professionally. As much as it was possible to carry out such an operation at that time. It is not clear, however, why such a painful operation was required for the gall, all the other teeth of which, apparently, were in order.

The largest star (Pistol Star) at the center of the Milky Way was discovered by astronomers using the Hubble telescope. It is 100 times larger than our Sun and 10 million times brighter than it.

The saltiest water was found at a depth of 3,6 kilometers in the Mediterranean Sea southwest of Crete. Its density is three times that of normal sea water. Scientists suggest that such salty waters could have formed over salt deposits that formed five to six million years ago in an area that was subsequently covered with water. Now these salty waters have formed a kind of lens with an area of ​​​​6,5 square kilometers.

The most sensitive seismograph was designed in Holland. He is able to capture vibrations with an amplitude of 10 to the minus eighteenth power of a meter. For the manufacture of this device, scientists used a niobium ingot weighing one and a half (!) Tons. At current prices, this ingot pulled 9000 dollars. This material, due to its properties, is ideally suited for registering gravitational waves. The trouble, however, is that gravitational waves with such amplitudes do not often come from space to Earth - no more than every five years, and perhaps every hundred years.

The oldest chewing gum in Europe was found in Sweden. Its age is 6500 years, and it is a piece of chewed birch bark. This is surprising, since natural chewing gum was usually made from pine resin.

Prof. General Dragomirov of the Academy of the General Staff, wrote about the Maxim machine gun: If the same person had to be killed several times, then this would be a wonderful weapon, since at 600 rounds per minute there are 10 of them per second. Unfortunately for fans of such a rapid release of bullets, it is enough to shoot a person once, and then shoot him in pursuit while he falls, as far as I know, there is no need. True, there are devices that disperse bullets, but, again, unfortunately, such musicians have not yet been born who would be able to change the direction of the barrels 10 times per second.

There are salty rivers on Earth. So, in the Solyanka River, which flows into the Lena River near the city of Olekminsk, there are 21 grams of salt per liter of water. Large streams flow in the same area, in which the salt saturation reaches 70 grams per liter of water. This phenomenon is explained by the fact that there was once a sea on the territory of Yakutia, in the lagoons of which powerful salt layers settled. Some of them are up to 15 meters thick. Water streams, penetrating through these layers, are abundantly saturated with salt.

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. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of ​​controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog ​​owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>
