It is estimated that in 1997, about 100 thousand industrial robots were added to the world, with three quarters of them installed in factories in Japan, the USA, Germany, Italy, France and England. By the year 2000 there will be almost a million robots in the world.

It is assumed that samples of terrestrial rocks could be preserved on the Moon, knocked out millions of years ago by impacts of large meteorites and flying to our natural satellite. Perhaps they will be able to find traces of ancient life, long destroyed by geological processes on Earth.

Access to the famous French cave of Lascaux, which contains a rich collection of rock art from the Stone Age, has been closed. Already since 1963, no more than five people a day were allowed there - scientists and honored guests of France. The breath of visitors destroys ancient drawings. Now the artificial climate installation is being replaced, after the repair the admission will be renewed, but, apparently, in the previous limited sizes. However, there is an exact copy of the drawings in the form of huge color photographs pasted on the vaults of an artificial cave built nearby.

Progress in the production of digital cameras is clearly visible in the following example. Twenty years ago, a matrix for such a camera had half a million photosensitive elements and cost half a million dollars, since 99 out of 100 manufactured matrices turned out to be defective. Therefore, there were only a few such cameras around the world, and they were used mainly in space research. Now such a camera costs $ 30, but few amateur photographers are content with such a low resolution.

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. ... >>

Global flood delayed 30.05.2019

Under the thickness of the Antarctic ice, scientists have discovered a tectonic relief that has a huge impact on the melting of the largest ice shelf on the continent.

Hidden from prying eyes, the rock has controlled the flow of water around the giant Ross Ice Shelf for hundreds of millions of years. This shelf currently acts as a critical buffer to prevent more Antarctic ice from being washed out into the open ocean.

The researchers found the subglacial rock thanks to the IcePod scanning system, which measures the height of the ice shelf, its thickness and internal structure, as well as the magnetic and gravitational forces of the rock on which this ice rests. Essentially, IcePod can peer through hundreds of meters of ice to reveal underlying rock structures that can't be seen from satellites.

The geological boundary between East and West Antarctica has created a barrier under the continent that protects the Ross Ice Shelf from warmer waters and further melting.

"The geologic boundary makes the seafloor in eastern Antarctica much deeper than in the west, and this affects how ocean water circulates under the ice shelf," says marine geologist Kirsty Tinto of Columbia University.

As a result, this barrier slows down the drift of approximately 20% of all Antarctic ground ice into the ocean. If all this mass of frozen water ended up in warmer regions, then sea levels would rise by as much as 11,6 meters. This is critical for many coastal areas and settlements around the world - they are unlikely to have survived such a massive flood.
