Where and when did people take shelter from bad weather in armadillo shells?

In the Pleistocene era, glyptodons, giant relatives of modern armadillos, lived in South and Central America. Glyptodon was similar in size to the Volkswagen Beetle.

There is evidence that the Indians hunted them and used the shells of glyptodons as shelter from the weather.

Presumably, people completely exterminated the glyptodons about 10 years ago.

What is a whirlpool?

When we think of whirlpools, we imagine a huge swirling mass of water that pulls people and ships in, bringing destruction and death. Although whirlpools are dangerous, they are not able to suck in or absorb anything.

Let's see what a whirlpool is. You have probably observed small whirlpools in the stream. They form where the shore protrudes into the stream and imparts rotational motion to the stream.

Rotating in a small space, the water tends to the outer edge of the whirlpool, creating a recess in the center. This is the result of centrifugal force. It is this force that keeps the water in the bucket when we spin the bucket.

What is the nature of the large whirlpools that supposedly pose a danger to ships and people? When one wave overtakes the previous one, ocean currents get a rotational motion. This is especially common in narrow straits between islands and land areas.

If such a narrow strait is of sufficient depth, when the tide passes through it, we observe the formation of funnels in a rotating mass of water. But, as we said, this does not happen in the open oceans. A whirlpool in the ocean is just a turbulent movement of water on a large scale, that is, the rotation of water.

Whirlpools are observed in various parts of the world. The most famous are three of them - the Maelstrom, Charybdis and the whirlpool downstream from Niagara Falls. Maelstrom is located off the coast of Norway, Charybdis - in the strait between Italy and Sicily.

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 ... >>

How to wake up quickly 18.01.2011

At the World Congress of Sleep Researchers, recently held in Texas (USA), a group of physiologists from Stanford University reported on a new way to quickly "bring to life" a sleepy person. This is done with short bursts of bright white light.

Volunteers who fell asleep at night were awakened two hours after falling asleep and the reaction time was checked. It, of course, was slow compared to the reaction of a waking person. But, if the awakened were irradiated once a minute with bright flashes of light lasting two milliseconds (approximately like a modern flashlight), they quickly came to their senses and the reaction time was reduced. Improved, according to sleep deprivation, and general subjective well-being.

Scientists believe that flashes can cheer up both workers on the night shift and sailors during the "dog watch".
