Does the turtle have a voice?

If we mean the voice, as we usually understand it, then the answer is no. But there are giant turtles that purr, growl and even roar! Turtles are a large family of reptiles, which are divided into three groups: land, marine and freshwater. Did you know that this family is older than the dinosaurs?

Perhaps the reason for the "voicelessness" of turtles is that they generally do not need a voice to protect themselves. After all, they have a wonderful carapace made of a bone base covered with horny plates. The shell consists of two parts, the upper of which covers the back, and the lower one protects the belly of the turtle. Through the holes between these two parts, the turtle can stick out its head, neck, tail and paws. Turtles reach amazing sizes.

The largest in the world is the leatherback turtle. Its weight reaches 450 kilograms. But this is a trifle compared to some varieties of extinct turtles. One of these species is called colossohelis. It was a giant tortoise that lived about 5 million years ago, and in the Natural History Museum in London you can see the complete skeleton of one of them. The shell is comparable in size to a small car, and if you install an engine and wheels on it, then you can safely drive through the streets of London! It is also believed that turtles are able to live to an advanced age. The giant tortoise lives longer than any vertebrate.

Numerous cases of life expectancy of such turtles up to 100 years or more have been recorded, and there are also those who have lived for about 200 years!

What causes champagne to foam?

Not because of carbon dioxide, but because of dirt. In a perfectly smooth and clean glass, carbon dioxide molecules evaporate imperceptibly, and for quite some time it was believed that the formation of bubbles was caused by minor defects in the glass. Modern photographic methods have shown, however, that all these almost invisible nicks and cavities are too small for bubbles to stick to them, and that in fact the formation of bubbles is caused by microscopic particles of dust and fluff, which are invariably present in absolutely any glass. In the language of technology, it is the dirt / dust / fluff present in the glass that plays the role of condensation nuclei for the carbon dioxide dissolved in the drink.

According to Moet & Chandon, there are 250 million bubbles in any average bottle of champagne.

Chekhov's last words were: "I haven't drunk champagne for a long time."

German medical etiquette of that time required that the doctor, when there was no hope of salvation, offer the patient a glass of champagne.

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 ... >>

Micro robot with a brush 10.11.2005

A self-propelled microscopic robot with its own muscles has been created at the University of California (USA).

This is an elastic metal bow 50 micrometers long, on which a layer of rat heart cells is grown. When the device is placed in a glucose solution, which is the food for the cells, the muscle layer begins to contract, then pulling the ends of the arc towards each other, then releasing them. As a result, the robot crawls along the substrate at a speed of up to 40 micrometers per second.

In another American laboratory, they learned how to grow brushes from carbon nanotubes one hundredth of a millimeter long.

In the future, perhaps, doctors will be able to launch self-propelled robots with brushes into the circulatory system to clean blood vessels from cholesterol deposits. But first, the creators of the nanobrush want to test how durable it is, and whether individual bristles will fall out along the way, harming the cells lining the vessel.
