Are jellyfish dangerous?

Jellyfish are the strangest sea creatures because they are made entirely of a gelatinous mass. They do not look like fish and are not their relatives. The sting serves as protection for them, which causes discomfort and can cause dangerous consequences.

The shape of a jellyfish resembles an inverted bowl. Under the bowl is their digestive system. The digestive system ends in a tube that hangs down from the center and has a bell at the bottom. The tentacles located around the circumference of the bowl are used for collecting food and for swimming. Between the tentacles are nerve centers and sensory organs. The cup-shaped body of a jellyfish consists of two thin layers of tissue with a jelly-like layer between them. If a jellyfish is pulled out of the water, it will dry out very quickly, because its body is 98 percent water. Of course, if the jellyfish is small, then the burns from its sting may not be very dangerous. But with big ones it's different.

Experts say that there are jellyfish in which the body reaches four meters in diameter, and tentacles - up to 30 meters in length. If a jellyfish like this "hugs" you, then you may have difficulty breathing, or partial paralysis may occur. The Portuguese soldier, one of the largest jellyfish, can kill and eat a whole mackerel.

On the coast of Australia, the sea wasp jellyfish is known to be the cause of many deaths. What makes a jellyfish dangerous is its tentacles. Some of them are equipped with thorns that dig into the body of the victim. The spines are associated with poisonous glands that kill or paralyze the victim.

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 ... >>

Metals in champagne 15.10.2004

A reliable way to distinguish real champagne from Soviet champagne has been found: the composition of trace metals in Champagne wine is unique.

Spanish chemists from the University of Seville measured microdoses of 16 metals in 18 samples of sparkling white wines from Spain and 17 samples of real champagne using atomic spectroscopy. It turned out that the samples clearly differ in the composition of these trace elements passing into wine from the local soil. So, real champagne contains twice as much zinc and half as much strontium as Spanish wines.

The analysis distinguishes between the surrogate and the original with XNUMX% accuracy.
