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. ... >>

Immortal quantum particles
21.06.2019
Theoretical physicists from the Technical University of Munich and the Institute for Physics of Complex Systems. Max Planck discovered that things that seem unthinkable in the everyday world are possible on a microscopic level.
“Until now it was assumed that quasiparticles in interacting quantum systems decay after a certain time. Now we know that the opposite is true: strong interactions can even completely stop the decay,” explains Frank Pollmann, professor of theoretical solid state physics at the Technical University of Munich. One example of such quasiparticles is a phonon - a quantum of vibrational motion of crystal atoms.
The concept of quasiparticles was invented by the physicist and Nobel Prize winner Lev Davydovich Landau. He used it to describe the collective states of many particles or, more precisely, their interactions under the influence of electric or magnetic forces. Due to this interaction, several particles act as one.
From a physical point of view, this oscillation is a wave that is transformed into matter, which, according to quantum mechanical wave-particle duality, is possible. Therefore, immortal quasiparticles do not violate the second law of thermodynamics. Their entropy remains constant, and decay is stopped.
This discovery also explains phenomena that have baffled scientists so far. Experimental physicists have measured that the Ba3CoSB2O9 magnetic compound is surprisingly stable. Magnetic quasiparticles - magnons - are responsible for this. Other quasi-particles - rotons - ensure that helium, which is a gas on the surface of the Earth, at absolute zero becomes a liquid that can flow indefinitely.
