Can people who are blind from birth fully use their sight after gaining it?

People who were blind from birth, but then cured, cannot at first recognize by sight and without the help of touch the objects they have previously touched. This conclusion was made by the authors of a study with Indian children from 8 to 17 years old, who returned their sight. However, after a few days, the children coped well with such a task. This disproves the theory that people who are blind from birth will not be able to fully use their vision after being healed.

How much longer can the sun shine?

Every second, our luminary loses about four million tons of its mass, which is converted into radiation energy. This can continue for another 4-5 billion years, until the star turns into a red giant.

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 ... >>

Volvo FE Electric garbage truck 09.05.2018

Volvo Trucks has unveiled the second model in its range of electric trucks. She became an electric garbage truck FE Electric.

The FE Electric garbage truck is equipped with two electric motors capable of delivering up to 370 kilowatts (about 500 horsepower) and a two-speed transmission. The maximum authorized weight of the FE Electric is 27 tons.

The machine can receive a battery pack with a capacity of 200 to 300 kilowatt-hours; at maximum capacity, Volvo Trucks says the garbage truck will be able to travel up to 200 km on a single charge.

The first FE Electrics are expected to hit the roads of Hamburg, Germany in early 2019.
