Why is the sky blue during the day and red during sunset?

The short-wavelength components of the solar spectrum are scattered in the air more than the long-wavelength ones. This is why we see the sky as blue, because blue is at the short wavelength end of the visible spectrum. For a similar reason, during sunset or dawn, the sky on the horizon turns red. During this time, the light travels tangentially to the earth's surface and travels much longer through the atmosphere, causing much of the blues and greens to escape direct sunlight due to scattering.

Why does an opossum hang on its tail?

There are many things about the opossum that make it a strange and interesting animal. For starters, did you know that opossums belong to a group of animals called marsupials? The females of these animals have a bag on their belly, in which the cub usually develops.

The most famous representative of the marsupials is the Australian kangaroo. The length of the body of the opossum can range from 23 to 50 cm, and the length of the tail is 23-33 cm. The coat of the opossum is light gray in color. It is absent only on its round ears, narrow tail and toes. The inner toe of the possum's hind foot can bend and touch any other toe. The opossum uses its hind legs as "hands". Like the long tail, these legs help the opossum to climb trees.

In general, the opossum spends a lot of time in the trees, hunting and eating there. To free its paws for eating, the opossum wraps its tail around a tree branch and eats, holding its food in its paws and hanging upside down. And almost everything is eaten by possums! Their "diet" includes small mammals, insects, small birds, eggs, lizards, crayfish, snails, fruits of all kinds, and mushrooms. At night, possums like to visit orchards and chicken coops.

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 ... >>

plankton vs plastic 09.03.2018

A scientific study has shown that tiny zooplankton are able to digest microscopic fibers of plastic (less than five millimeters in size) before releasing them back into the environment in an even smaller form.

Study author Amanda Dawson discovered the phenomenon while working on a project with microbeads - a polyethylene plastic often used in beauty products such as facial scrubs - to test their toxic effects in a special krill aquarium.

“We realized that krill really destroys plastic, it was amazing,” said a researcher from Griffith University in Australia. easier to deal with."

The problem of plastic pollution is widespread and rapidly deteriorating. Every year, more than eight million tons enter the ocean, causing enormous damage to marine ecosystems and killing an estimated one million seabirds, one hundred thousand marine mammals and untold numbers of fish.
