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. ... >>

Breathing affects memory
28.08.2023
New research shows that our breathing and its effect on the brain can enhance or impair our ability to form memories, and these findings could help treat brain disorders and mental health issues.
The body's natural and spontaneous respiratory behavior is known as medullary respiratory activity, under the name of the medulla oblongata, the respiratory control center in the brain. Of particular importance is a small cluster of neurons in the so-called Pre-Betzinger complex, which is located inside the medulla oblongata.
Breathing is a fundamental action in maintaining life in mammals, says neuroscientist Nozoma Nakamura of Hyogo Medical University in Japan. Although the details of the influence of respiratory function on brain states remain unclear, recent research suggests that breathing may play an important role during online brain states.
In this new study, scientists interfered with PreBotC in genetically engineered mice. They found that when mice were temporarily stopped breathing, the animals were less able to form important memories during tests of object recognition and conditioned fear.
Moreover, pauses in breathing also affected the activity of the brain's hippocampus (key for storing long-term and short-term memory) when recalling memories. In subsequent tests, forced irregular breathing improved the mice's memories, while slowing their breathing worsened their memories.
Previous research by the same team has already demonstrated that the transition from exhalation to inhalation at the beginning or within a memory task, technically known as the transition from exhalation to inhalation (EI) or the beginning of inhalation, makes people slower and less accurate when mentioning information.
After that, a study was conducted in which, using brain scans, a link was established between memory impairment and deactivation of the temporoparietal junction (TPJ). The temporo-parietal junction performs many different tasks, processing information from outside and inside the body, and determining responses.
The researchers speculate that certain types of breathing, including switching to rescue breathing, reset the processing performed by the TPJ, and that TPJ may be involved in the fluctuations in memory performance that are seen in mice. These effects have yet to be replicated in humans, which is one area of future research.
