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. ... >>
| Random news from the Archive Chocolate is not just a delicacy, but the mood and health of women
10.02.2024
Chocolate is not only a delicious treat, but also a powerful stimulator of endorphins and serotonin, which have a beneficial effect on mood and help reduce stress levels. This explains why one in four women consider chocolate the most enjoyable source of pleasure. The data comes from a survey conducted by the Italian Society of Gynecology and Obstetrics (Sigo).
For many women, chocolate is one of the strongest passions after intimacy. In addition, this product helps reduce pain. During premenstrual syndrome, about 68% of women use it, and during menstruation - up to 83%.
The study results indicate that chocolate improves mood in 97% of women surveyed and promotes feelings of arousal in 50% of them. They note that this delicacy relieves menstrual pain, eliminates headaches, relieves bloating and helps with insomnia.
The study confirmed that chocolate is an excellent aphrodisiac. Doctors note that women who regularly consume chocolate tend to be more sexually active and enjoy their sex life more.
It is important to note that the positive effects are associated specifically with dark chocolate, which contains more cocoa and less sugar compared to milk. Moderate consumption is limited to a few pieces per day, which helps avoid excess calories and sugar intake. People with high blood sugar levels should control their chocolate intake.
Chocolate, especially dark chocolate, is not only a tasty treat, but also a healthy product that can influence the mood and general condition of women. By supporting the production of endorphins and serotonin, it can be an integral part of your health and well-being. It is important to remember in moderation and choose a quality product for maximum benefit.
