Is a hedgehog immune to snake venom?

Yes, our ordinary hedgehog, which, by the way, does not disdain snakes, has such immunity. Even the cobra, which, fortunately, does not occur in our area, is not afraid of him. Other animals, such as rabbits, have the same immunity.

How does rice grow?

Did you know that almost half of the world's population lives almost exclusively on rice? Most of these people live in Asia, but rice is of great importance to Europeans as well. There are thousands of varieties of rice that differ significantly from each other.

Wild rice grows on shallow lakes in northeastern Canada and the United States. It is only distantly related to the cultivated rice that most people eat. And where there are hills or plateaus, rice can be grown in dry fields on the plateau, like other crops.

But most of the rice, which is called lowland rice, is grown on flat, muddy soil that has been deposited by water. Such soil is usually found on the banks of rivers and lakes. This soil is not only wet, but it can also be flooded during rice growth. Rice is planted in specially prepared seed nests. The seedlings are then transplanted into flat fields surrounded by dams called checks. The fields are then flooded with water, which passes through special gates in the walls surrounding each field.

During the ripening of rice, the rice grower must maintain a water level of at least 13 centimeters. For weeding, the water is drained and the weeds are pulled out by hand.

Then, before the leaves turn from green to yellow, the fields are drained again for harvest. So, as you can see, growing rice is very labor intensive. No one knows where rice first appeared, but it is one of the oldest crops.

The Chinese have been growing rice for 5000 years! But perhaps rice first appeared on the banks of lakes and rivers in India, and from there it spread to other countries. In Europe, rice began to be grown in the fifteenth century in Italy.

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 ... >>

wifi on sheep 28.12.2014

British researchers plan to equip sheep with Wi-Fi hotspots to bring high-speed Internet access to rural areas. Sheep are no strangers to wearing equipment: in the summer of 2014, they played the role of operators in the Tour de France.

A team of researchers led by Lancaster University professor Gordon Blair plans to explore the possibility of installing Wi-Fi hotspots on sheep farms in British Wales, reports The Daily Mail.

According to the researchers, this can solve the problem of providing high-speed Internet access to remote rural areas. The group received 171,5 thousand pounds sterling (about 14,5 million) for this project.

Researchers suggest that it would be possible to equip remote areas with Internet access by turning sheep grazing in wide open spaces into a chain of wireless signal transceivers.

"This could address the typically slow access speeds and poor network coverage in much of the UK's rural areas," notes The Daily Mail.

Wi-Fi modules can be integrated into digital collars - devices for monitoring the movement of sheep that farmers use.

We add that earlier sheep were already used as a kind of transport for equipment. In July 2014, these animals were equipped with cameras to film the prestigious Tour de France cycling race held in Yorkshire. The cameras on the sheep were controlled remotely.

In addition to the Internet, Blair's team will study the problems of pollution, floods and droughts. Within the framework of the project, water level sensors will be installed in the rivers on the banks and precipitation sensors. A similar system has been installed in Honduras by researchers at the Massachusetts Institute of Technology and Microsoft.

The authors of the project will try to implement one of the basic principles of the "Internet of things" - the ability of electronic devices to communicate with each other and send data to the Internet without human intervention. The researchers note that in rural areas such a concept is more difficult to organize due to the more complex landscape. However, the results are obvious - high-quality network coverage of remote areas and the availability of all kinds of sensors will help to cope with natural disasters and increase the efficiency of agriculture.
