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. ... >>

The brain is able to remember foreign words in a dream
19.06.2023
Recent studies by scientists at the University of Bern have confirmed an interesting feature of the brain: the ability to remember foreign words during sleep. The legend that sleep can promote more effective learning has received scientific support, although scientists remain skeptical of this claim. However, there is some evidence that the brain is able to process and store information received in certain phases of sleep.
Researchers have focused on slow wave sleep, especially its first phase. At this point, the brain goes through short periods of activity and recession that last about 30 seconds. A team of scientists led by Flavio Schmidig has developed an algorithm that predicts the exact timing of the next peak and fall of brain waves based on EEG data. This algorithm was used to conduct experiments on 30 volunteers who slept in the laboratory and were native German speakers.
During the experiment, volunteers were played short two-syllable words. One word sounded in their one ear in German, and the "translation" of this word, which is a random collection of syllables that do not exist in reality, sounded in the other ear. This approach excluded the possible influence of previous acquaintance with foreign languages. Half of the volunteers listened to these words during peaks in brain activity, and the other half during periods of recession. In total, each word was played four times, and the choice of words covered three categories: animals, places, and instruments.
After 12 hours, the effectiveness of this training was tested. The volunteers were again played the "translated" word and asked to assign it to one of three categories. As expected, with a random response, the probability of the correct choice was about 33 percent, and this is exactly the result of the group that listened to the words during the peaks of brain activity. The second group, which listened to the words during periods of recession, scored slightly higher at 37 percent, which is almost no different from random guessing. However, when rechecked 24 hours later, this group performed better, reaching 41 percent correct answers.
Statistical analysis confirmed that these results cannot be a simple random phenomenon. The researchers concluded that memory actually occurs when words are recalled during short bursts of brain activity during the initial period of deep sleep. However, the effect of this memorization turned out to be moderate, and its significance in learning remains relatively small. Rather, it demonstrates the very fact that the brain is able to perceive and store new information during sleep, but it is unlikely that this will be a significant help in the educational process.
