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. ... >>

Recyclable printed circuit boards 03.05.2024

Electronics play a key role in today's world, but the accompanying rise in e-waste is putting the environment at risk. In response to this problem, researchers at the University of Washington have developed an innovative technology that could change conventional wisdom about circuit board recycling. A team led by scientists from the University of Washington has created a vitrimer printed circuit board that has the unique ability to be recycled multiple times. Using advanced environmentally friendly polymers, the researchers developed a material that can be turned into a jelly-like substance using a special solvent. This opens the way for PCBs to be reused and recycled without significant loss of quality. Vitrimer printed circuit boards (vPCBs) represent significant advances in environmental sustainability. Unlike conventional plastics, which are susceptible to degradation during repeated recycling, jelly-like vitrimer retains its ... >>

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Saving apples from sunburn 10.08.2021

Washington State University researchers are testing a high-tech approach to preventing apple scorch in the face of global warming.

The summer sun helps the apples ripen and get their classic red color, but the heat often causes the fruit to scorch. While the leaves of the apple tree are able to absorb sunlight, the fruit also does not dissipate heat. Sunburn occurs in as little as 10 minutes, causing irregularities that detract from the quality and appearance of fruit, such as ugly brown spots.

Most apple growers in the US use sprinklers to cool the canopy of orchards on hot days. But trees absorb this extra water and use it to grow shoots and leaves at the expense of fruits.

As part of a project jointly funded by the USDA's National Institute of Food and Agriculture and the National Science Foundation, Hoth's team is developing a horticultural sensor system. The technology must detect the surface temperature of the fruit and fine-tune the supply of cold water for evaporative cooling.

Using infrared cameras and miniature weather stations, the prototype activates the top sprinklers exactly when they are needed, minimizing the negative effects of spray cooling. As an added benefit, the scientists have also developed a smartphone app that uses data from a nearby weather station as well as a low-cost thermal/RGB camera to measure fruit temperature and heat stress hazards.

Khot systems can send real-time data to growers to help them make decisions about managing heat stress and, in the future, storing and marketing their fruit, as sun-burnt apples go bad quickly in storage.
