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. ... >>

Heat resistant memory for interplanetary missions 28.07.2019

Studies of the two planets closest to the Sun, Mercury and Venus, have always been complicated by the fact that the conditions on their surfaces are extremely unfavorable. For example, Mercury can heat up to 430 ° C, and Venus, due to the characteristics of the atmosphere, even more. Therefore, any apparatus that studies these celestial bodies up close must be prepared accordingly.

Modern electronics are very sensitive to heat, and temperatures of hundreds of degrees Celsius are detrimental to them. However, scientists have been trying to solve this problem for many years and it seems that they have achieved some success. For example, Arizona State University recently announced the development of next-generation electronics modules under the NASA-funded HOTTech program, on the basis of which it was possible to create memory elements that can withstand high temperatures - up to 300 ° C and even higher.

Gallium nitride was taken as the basis material for creating high-temperature electronics. The fact is that silicon, which is traditionally used to create microprocessors and memory modules, has a relatively low band gap (this indicator determines the minimum energy required for an electron to move from the valence band to the conduction band) - only 1,12 eV. At the same time, for gallium nitride, it is 3,4 eV, which allows devices to operate normally at much higher temperatures. At the same time, it is noted that this is not the only semiconductor material with a wide band gap being studied as part of the high-temperature electronics program. Another worthy candidate with a wide bandgap is silicon carbide.

The memory device was fabricated by chemical vapor deposition on a gallium nitride substrate. During testing, the memory module showed stable performance over the entire range from 25 to 300°C. When the temperature rose to 350°C, control over the processes was lost, but it was restored after the temperature dropped to room temperature. Thus, even in the case of extreme heating, the memory module itself will not be lost, although it will stop working normally for a while. At the same time, as Yuji Zhao notes, the results of the work are intermediate and the next step will be the creation of memory modules that can withstand up to 500 ° C in normal mode, and with such electronics it is already possible to explore the surface of even Venus, even Mercury.
