Where does the woman live who passed her driving test on her 960th attempt?

Cha Sa Soon, 69, from South Korea, got her driver's license in 2010. She made her first attempt to pass the exams in 2005, but failed. Since then, she took the theoretical part of the exam almost every day, and she managed to overcome the minimum barrier from the 950th time. She spent 10 more attempts on the practical part. The inflexibility of character made this woman a national heroine, and Hyundai, after the successful completion of the story, presented her with a car.

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. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Hydrogel molecular muscle contracts in light 22.01.2018

American scientists have managed to create a muscle contracting in the light, which at the same time can lift a small load. The experts used polyethylene glycol hydrogel as a material for their development.

Scientists at the University of Washington, led by Jonathan Barnes, have managed to develop a molecular muscle that reacts to light. Previously, experts have created a unique polymer that can change color and shape. On its basis, systems were created that respond to redox reactions in solution, and then outside it.

At this point in their research, the scientists set out to prove that the polymer they had developed could do the job. To do this, a small weight was placed on a hydrogel molecular muscle and a beam of light was directed at it. After some time, the polymer shifted the load by several centimeters.

The authors of the study plan to “teach” the muscle to carry a heavier load in the future.
