  • in the morning fog spreads over the earth;
  • abundant dew;
  • smoke from chimneys rises vertically;
  • wind from the north, east or south.

Why don't snakes have legs?

The absence of legs in modern snakes does not mean that they never had limbs. But how and when the snakes "lost" their legs is not known to science. Some scientists believe that some species of shrew lizards, which have survived to this day, were the ancestors of the snake. All these lizards have very short legs or none at all.

But, despite the fact that once all the legs of the snake disappeared at once, they by no means lost the ability to move and do without them very well. Convex plates located on the belly help the snake to move.

There are four different ways for snakes to move.

1. Lateral wave-like movement. The snake sequentially describes wavy curves with its body, similar in shape to the letter S, and, pushing off the body from the unevenness of the soil, glides forward.

2. Rectilinear motion. Small groups of plates on the belly push forward part of the body of the snake, while the rest of the plates are thrown back, creating a support for the body. After that, the plates that have moved forward hold the body while the plates of the back of the body are pulled up to them.

3. Spiral motion is used for tree climbing. The snake wraps its tail around a tree trunk and, throwing up the front part of the body, catches on the tree at a certain height, after which it pulls up the lower part of the body.

4. Side travel. Moving in this way, the snake throws the front part of the body sideways, after which it pulls up the back part and repeats the same operation.

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 ... >>
