Where are newborns dropped from 15 meters to grow up healthy?

In some Indian villages, there is a ritual to throw newborns from the roof of the temple. For example, in the village of Musti, Maharashtra, children are thrown from a height of 15 meters onto a tent stretched below.

The rite for their babies is ordered by both Muslim women and Hindu women, who believe that this test will bring the child health and good luck in the future.

What funny day is Internet Day?

Archbishop Isidore of Seville, who lived in the 6th-7th centuries, wrote the 20-volume work "Etymology", in which he systematized the knowledge available at that time in the world. It is he who is considered the first encyclopedist, and now many Catholics revere him as the patron of the Internet. It's funny that Internet Day is celebrated on the day of the death of Isidore of Seville on April 4 - when written in numbers, this date coincides with the most recognizable 404 error code.

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 ... >>

Flying robot the size of an insect 09.02.2022

Scientists from the University of Bristol (UK) have developed small drones that can fly by flapping their wings. The achievement was made possible by the use of an unprecedented electromechanical principle for propulsion of miniature wings, which does not require a traditional transmission.

Thanks to the unique development of British scientists, in the future, miniature drones may appear that will buzz and fly like insects. Such devices may have many civil and military applications. In particular, they can be used for environmental monitoring and search and rescue operations.

In an attempt to create miniature drones that fly like insects, engineers used gears and other complex mechanical devices to move the wings up and down. This gave the systems excessive complexity and mass, which affected the dynamic qualities.

Inspired by bees and other insects, Bristol University roboticists led by Professor Jonathan Rossiter have created an artificial muscle system called the Liquid-amplified Zipping Actuator (LAZA). Thanks to LAZA, the drone can flap its wings without gears and other rotating mechanisms.

LAZA greatly simplifies the wing flapping mechanism, potentially allowing drones to be reduced to the size of an insect. As the scientists point out, the equipped LAZA robot has more power than an insect of the same weight, and can fly at speeds up to 18 body lengths per second. In addition, LAZA provides a stable flight over a million swipe cycles, which allows you to perform long flights.

Scientists expect LAZA technology to be the basis for miniature drones that fly "like insects" in the future. According to Tim Helps, one of its lead developers, LAZA allows electrostatic force to be applied directly to the wing, without the need for a complex and inefficient powertrain. As a result, we get better performance and a simpler design. This opens the door to a new generation of miniature aircraft that can be used to inspect offshore wind turbines, among other things."

And Professor Rossiter points out that "the creation of miniature drones is a huge, very complex and urgent technical problem. LAZA is an important step towards the emergence of "artificial insects" capable of performing a range of tasks, from pollinating plants to searching for people in ruined houses.
