Where does an orchid grow, which spends its entire life cycle underground?

Rhizantella Gardner, an orchid family endemic to Australia, blooms with small maroon flowers. Its uniqueness lies in the fact that the plant spends all life stages underground.

It is also pollinated by underground insects - such as termites.

Who is a swordsman?

The horseshoe crab is a very interesting creature. To begin with, although it is called "king crab" in English, it is not a crab at all, although it is a relative of crabs and spiders. Its scientific name - Limulus Polyphemus - alludes to its amazing eyes. This animal has four eyes. Two eyes protrude from the sides, and two more are set very close together on the front of the head and almost merge into one eye, similar to the one that Polyphemus the Cyclops had in ancient Greek myth. Scientists call horseshoe crabs "living fossils". The body of the polyphemus has changed very little over the millions of years of its existence. Imagine, they exist in this form for almost two hundred million years!

The entire body of the horseshoe crab is protected by a thick shell. Its long and pointed tail resembles a sword. This sword is serrated. When the horseshoe crab turns over in a wave, it uses its tail to assume a normal position. The horseshoe crab has six pairs of legs. He uses four pairs to move along the sandy bottom of the ocean. And a strong back pair of legs - in order to push off the bottom and swim. With short front paws, he also pushes food to his mouth. The mouth is almost completely hidden among the legs used for walking, so it is difficult to see it. Its "shoulders", or the inner joints of its paws, resemble real tongs. With their help, he grinds his prey before putting it into his mouth.

Horseshoe crabs feed on almost everything, from small clams, worms and fish eggs to algae and decaying organisms. Horseshoe crabs breathe with flapped gills. In each leaf there are about one hundred and fifty thin plates, with the help of which it consumes oxygen dissolved in water. As long as these plates remain moist, the animal can breathe. Horseshoe crab cubs hatch from small eggs, appearing without a tail and with a very soft shell.

After four weeks, they grow out of their shells, which do not grow with them. The animal must shed this shell, that is, shed. Until the horseshoe crab reaches its full height, from thirty to sixty centimeters, it can change its shell up to twenty times!

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 ... >>

LeTV X1 door lock with 3D face ID 26.08.2022

A new product from LeEco's Smart ecosystem is capable of 3D face recognition, opening a door in seconds. It can adapt to different facial poses even with glasses or hairstyle changes. X1 smart door lock uses artificial intelligence and 3D face recognition technology to accurately identify faces.

The identification technology is secure enough to prevent penetration through face masks, photos and videos. X3 1D smart door lock can generate detailed information in different situations, both day and night. 3D infrared night vision with optional light recognition is a key feature of the new door lock.

It also features a 1080p HD screen, 160 degree wide viewing angle and remote video intercom. The smart door lock can also take pictures and offers a cloud storage option. There are eight ways to unlock the doors and ten security measures.

The LeTV Smart Door Lock X1 has a 4200 mAh battery, which ensures the wide use of the gadget. The product is offered at a starting price of 1699 yuan (about $247).

This product is not LeEco's first smart door lock and builds on the security and safety features of its predecessors. However, there are some doubts about the fidelity of the device in terms of accuracy.
