Where do ants live that can count the number of steps taken?

The red phaeton is a species of ants living in the Sahara, feeding on other insects that have died from the heat. In search of prey, they run far from their holes and periodically measure the angle of direction to the Sun in order to return back by the shortest route. Also, these ants somehow know how to count their steps, which is important in the desert, where smells quickly disappear. Scientists have confirmed this in an experiment: some kind of stilts were attached to the paws of some chaises, because of which, on the way back to the hole, they ran too far, measuring a given number of steps. For others, the legs were shortened, and they did not reach their shelter.

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 danger of extinction of insects 05.04.2020

Insects make up 80% of the world's living creatures. Yes, this includes plants. And only 10% of them bring some kind of harm to a person: they spread diseases, destroy crops, and finally bite. But even they are involved in maintaining the food webs on Earth. No insects - no birds, amphibians and reptiles that feed on them. Accordingly, predatory reptiles, birds and mammals, which cannot survive without insects, will soon die. No insect pollinators - no plants. And that means all herbivorous creatures, including vegans. It doesn't matter what you eat - everyone will be left without food.

In 1948, the Swiss chemist Paul Müller received the Nobel Prize "for his discovery of the high efficacy of dichlorodiphenyltrichloroethane (DDT) as a contact poison." It was the first and only time in history that a scientist received the highest award for discovering a pesticide. But very quickly, scientists became disillusioned with the crude pesticide. On the one hand, he prevented a typhus epidemic in Naples in 1944, and according to WHO statistics, antimalarial campaigns using DDT saved five million lives. But besides this, the pesticide destroyed complex bonds in nature, along with conditionally harmful ones, killed many beneficial insects, including pollinators. It turned out that the poison poisons plants, warm-blooded animals and even humans, but that's a completely different story. Paradoxically, the problem of combating harmful insects turned out to be much more difficult than initially thought, and having killed all the "bad" insects at once, the biosphere as a whole fell down.

Food today can already be synthesized in a test tube, and plants can be artificially pollinated, although this is time consuming and expensive. There are already robotic pollinators that are designed to help the rapidly dying bees. They will not replace natural pollinators, but they will help delay the apocalypse, in comparison with which the COVID-19 pandemic will seem like a children's party. And even theoretically it is impossible to artificially pollinate all plants, as insects do. This means that vegetation will be reduced on the planet and very soon we will not have enough oxygen.

And what to do with garbage and corpses? With the remains of wild living creatures? After all, insects, along with fungi, worms and bacteria, are involved in the decomposition of organic matter and partially inorganic matter. And they do it faster than all the above builders of the biosphere. Add to this that diseases will not only continue to spread, but it will happen much faster.

It can be argued that the absence of insects will lead to a change in the diet of insectivorous animals and birds. However, this is a long process that will not have time to complete. Those single individuals that will switch to plants and meat will also not have a chance, because there will not be enough plants, and then meat.
