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. ... >>

Touch displays without the use of rare earth elements
06.01.2014
3M plans to start manufacturing touch screens based on silver nanowires in 2014.
The technology for the production of silver nanowires was developed by Cambrios Technologies. In the production of touch panels from nanowires, a thin electrically conductive layer will be formed. Previously, such a layer was made from a mixture of oxides of tin (10%) and indium (90% by weight). Compared to a mixture of indium and tin oxides, silver has better characteristics, and, in addition, is a more affordable material. To date, as the press service of 3M emphasizes, several designs of touch displays have already been patented for various devices, from full-size monitors to mobile phones.
One of the main advantages of silver nanowires is their flexibility. In addition, displays made with this material have shown high transparency (89%), which the company claims will enable higher contrast screens. The flexibility of the silver substrate will also allow the creation of curved displays. Moreover, there may be displays that can be rolled up. Next year, it is planned to increase the production volume to 600 thousand square meters. meters of touch screens per month.
Indium is a rare earth metal that is produced in the amount of about 700 tons per year, more than half of which is mined in China. At the same time, almost 30 times more silver is mined in the world every year, and its reserves in the earth's crust are estimated to be higher.
According to forecasts made at the beginning of 2010, indium should actually run out by the end of the decade: existing deposits will run out, and technologists will have to look for an alternative to this element, or develop new sources of it. In addition to silver, carbon nanotubes are also called an alternative to indium.
