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. ... >>
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 ... >>
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. ... >>

Battery of the future without sodium anode
10.05.2021
Scientists have created a prototype sodium-based battery without an anode. Unlike lithium-ion power supplies, it is cheap and does not pollute the environment.
A typical lithium-ion battery has two electrodes, a cathode and an anode. They transfer the ions in the electrolyte solution to each other as the device charges and discharges. Scientists from Washington University in St. Louis tried to replace lithium with sodium metal.
Why are researchers interested in him? The fact is that it is metallic sodium - a widespread material.
When creating a power source, scientists abandoned the anode, adding instead a thin layer of copper foil. It is located on the anode side of the current collector, which collects free electrons as the battery discharges and directs them to the device that is powered.
A thin layer of copper acts as one of the electrodes. The result is a power supply that is much smaller and cheaper to manufacture analogues. At the same time, the performance of such a battery does not suffer. The authors of the development note that such a battery will reduce the cost and size of gadgets.
When this experimental battery is charged, instead of ions passing from the cathode through the spacer material to the anode, they are deposited on copper foil and become a shiny, smooth metal. Then, when the battery is discharged, the material dissolves and the ions return to the cathode.
