Can butterflies smell?

Maybe it will surprise you, but butterflies and moths can see, have touch and smell. The taste of a butterfly is determined by the organs in the mouth, which is completely natural. And the smell is perceived by the antennae of the butterfly. There are species of butterflies that sniff with "noses" located on their paws! Many butterflies themselves emit a smell that they need for two purposes. With one smell they attract butterflies of the opposite sex, with others they scare away enemies.

The smell of male butterflies comes from small scales in pockets on the hindwings. During love games, the male emits this smell towards the female. The smell of many males resembles the smell of flowers and is pleasant to humans. Female butterflies produce smell with special glands on the body. The smell of females is unpleasant to humans.

Did you know that the taste organs of a butterfly are more sensitive than those of humans? They are more sensitive to sweets than our tongue. Their main food is flower nectar, which includes sugar, so they easily find it. When a butterfly detects nectar in a flower, it sticks its long proboscis in and sucks up the liquid.

Butterflies are able to distinguish colors well. They even perceive certain ultraviolet radiation that the human eye cannot see.

How were the Hawaiian Islands formed?

Hawaii is the youngest state in the US. They consist of a group of islands in the Pacific Ocean, approximately 2400 miles southwest of California. The state includes eight large and many small islands and covers an area of approximately 6420 square miles. According to one Hawaiian legend, there was once a goddess of volcanoes named Pele, who created the islands. From time to time it returns to the craters on the islands and starts volcanic eruptions.

Interestingly, the Hawaiian Islands are actually the tops of huge volcanoes rising from the bottom of the ocean. For example, the island of Hawaii ("Big Island"), which is twice as large as all the other islands combined, was formed from five volcanoes, the emissions of which were layered on top of each other. Two of them are still active and continue the process of building the island.

One of these volcanoes, Mauna Loa, erupts every few years. In 1950, it erupted for 23 days and lava flowed into the sea. The water became very hot, and because of this, many fish died.

Another volcano, Mauna Kea, is dormant. It is the highest mountain in the Pacific Ocean. The volcano rises to 4200 meters above sea level, but its base goes to a depth of another 5840 meters. If measured from the underwater base, then this volcano can be considered the highest mountain in the world.

On the island of Maui there is a Haleakala volcano with a height of 3055 meters. It is the largest inactive volcano in the world. Its crater is about 20 miles across and 830 meters deep.

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 ... >>

The character of a dog does not depend on the breed 16.01.2024

American scientists conducted a study in which the genomes of more than 2 thousand dogs were studied and published the results of their observations. The main conclusion of the study is that breed is not a determining factor in shaping a pet’s character, including its aggressiveness and tendency to obey the owner’s commands.

“Our analysis of the opinions of dog owners and the genomes of their pets showed that belonging to certain breeds explains only 9% of the variability in their behavior. This indicates that the characteristic behavioral traits of dogs were formed randomly during the evolution of their ancestors long before the advent of modern decorative dogs. varieties," the scientists note.

There are more than three hundred officially recognized dog breeds on the planet, but only a small number have been bred to perform specific tasks. Most breeds have appeared in the last three hundred years as ornamental varieties. In determining the breed of a dog, its exterior, appearance and similarity to “reference samples” play a major role. However, for owners, the character and behavior of their pet is more important: aggressiveness towards strangers and devotion to its owner.

A team of geneticists led by Professor Elinora Carlson from the University of Massachusetts at Worcester has found clear evidence that dogs' behavior has little to do with their breed. During the study, the genomes of 2,1 thousand dogs representing 78 breeds were deciphered. In addition, scientists conducted surveys among owners aimed at assessing eight key character traits of dogs.

Geneticists have identified 11 DNA sections that significantly affect the behavior of dogs, but are not associated with specific breeds. Further analysis of genomes and survey results showed that breed did not play a decisive role in shaping the character of both purebreds and mixed breeds of different breeds.

Belonging to a breed explained only about 9% of the behavior of pets. The remaining more than 90% of the variation in their character is due to mutations in genes passed on by individual dogs from their ancestors.

Research shows that dogs' personalities are largely determined by genetic factors unrelated to their breed. These results are important for understanding the behavioral characteristics of dogs and making adjustments to the upbringing and training of animals.
