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. ... >>

Growing plants in total darkness
15.07.2022
Biologists from the University of California have figured out how to completely eliminate sunlight and still accelerate the growth of plants. Using acetate as a carbon source, scientists have successfully grown several crops and food microbes in absolute darkness.
The new approach turned out to be even more effective than the natural one - for example, the production of yeast without light accelerated by a record 18 times. The prospects for the technology are enormous, the authors argue - artificial photosynthesis will simplify farming in cloudy regions, it will also feed astronauts and colonizers of other planets.
Despite the fact that photosynthesis has been the main process that stimulates plant growth for millions of years, sunlight has never been an ideal source of energy. On average, crops absorb only 3% to 6% of sunlight. By studying various salts and esters, the scientists concluded that acetate—the main component of regular vinegar—may work as a more efficient replacement system for photosynthesis.
During the study, scientists gave acetate to plants, bypassing natural photosynthesis - all the studied objects were in dark chambers without access to artificial and natural light sources. The team tested their technique on a variety of organisms, including yeast, green algae, fungal mycelium, cowpea, tomato, tobacco, rice, rapeseed and green peas. The result showed that all these organisms can be grown in acetate media in complete darkness and, in some cases, even more efficiently than in sunlight.
Acetate-supported common algae grew four times more efficiently, and yeast production sped up 18 times, according to published data. The secret to the success of the new technique lies in the fact that acetate builds its molecular building blocks into the work of plant cells - with it, crops quickly convert carbon dioxide and water into useful substances to stimulate their own growth. This artificial photosynthesis has the potential to change the paradigm of how plants feed humans.
It has been found that a wide range of crops can use acetate to build it into the basic molecular building blocks the body needs to grow and thrive. With some of the breeding and engineering techniques that we are currently working on, we could grow crops with acetate as an additional source of energy to increase yields.
In addition to eliminating sunlight, artificial photosynthesis reduces land requirements and the environmental impact of agriculture. In the long term, this approach will come in handy both on Earth and in space. The increased energy efficiency of plants, for example, will allow more crew members to be fed at a lower cost.
