Where do blue whales live?

First of all, what are blue whales? For most of us, all whales are the same. We do not think that there are many types of whales. Scientists divide whales into two groups: toothless and toothed. Some whales have whalebones hanging from the corners of their mouths. Whalebone - sinewy, keratinized substance, framed by a fringe along the entire length of the mustache from the inside. With these whiskers, whales filter a large amount of food from the water.

Baleen whales are the largest animals that have ever lived on Earth. More than dinosaurs? Yes! The blue whale, the largest member of this group, can reach 30 meters in length and weigh more than 110 tons, and even the largest dinosaurs did not reach this size. There are three families of baleen, toothless whales: right whales, minke whales, gray whales. Blue whales are the largest of the minke whales. They are found in seas around the world. There is no particular area or ocean that they would prefer.

These huge animals feed mainly on small fish or crustaceans, krill. The whale takes a mouthful of water and closes it. Gradually, he presses his tongue against the mustache hanging from the upper jaw. This way the sea water flows out and the food remains in the whale's mouth. Baleen whales differ from toothed whales in many ways, and sometimes it’s even hard to believe that they are relatives.

On which astronomical body is the Vodyanoy crater and the Kikimora dark spot?

Nearly all geographic features on Triton, Neptune's largest moon, are named after water spirits, deities, and monsters. For example, there is a crater named after Leviathan, as well as a line of craters "Chain of the Kraken". Astronomers have not forgotten about the spirits of Slavic mythology: one of the craters is named Vodyanoy, and one of the dark spots on the surface of the satellite is called Kikimora.

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 ... >>

A well-fed woman becomes more romantic 29.08.2015

Scientists at Drexel University investigated the relationship between food and romantic feelings in women. During the experiment, young girls were assessed the activity of different areas of the brain, and at the same time they were shown pictures of romantic content, and the young ladies themselves went to the experiment either hungry or well fed.

It turned out that the female brain reacts more vividly to romantic images just after eating - the neurons of the reward system responsible for the feeling of pleasure were activated more strongly on a full stomach.

Moreover, curiously, the response of the reinforcement system in this case was the same as for food. Some time ago, the same team of neuroscientists did similar experiments with girls who had been on a diet for a while, with those who were on a diet right now, and with those who had never been into diets.

It turned out that the brains of women who once restricted themselves in nutrition react to delicious food more strongly than those of the other two groups. That is, the pleasure centers worked more strongly on the image of a chocolate cake than on a picture with a carrot, and such a reaction occurred again in the participants who ate the experiment. Then it was concluded that the danger of becoming overweight most of all threatens those who have already quit the diet: even after eating a lot, they are more likely to eat something else "delicious".

But since the reward system responds not only to food, but also to other potentially pleasant stimuli, it was decided to repeat the same thing, only this time with sexually romantic images. Among the participants in the experiment were again those who were fond of diets, and those who lived without diets - and the brain activity in response to romantic signs in the former even more closely resembled the reaction of pleasure centers to food.

On the whole, the general conclusion is this: anticipation of pleasure from "relationships" and from food is processed in many ways by the same neural structures; the increased response to “romance” after eating may indicate that the neurons previously engaged in eating have now been freed up for a new source of pleasure. True, whether this manifests itself in communication with a potential partner will become clear only after additional psychological research.
