Where do snails get their shells from?

You have probably watched a snail protrude from its shell, moving its horns from side to side. Would you like to eat one of these? Not? But in some countries, for example in France, snails are considered one of the best delicacies!

Snails belong to the family of mollusks - animals without a spine. Some of them live in gardens, others in ponds, and some even in the oceans. But there are two main types of snails - those that have a shell, and those that are covered only by a thin mantle. Representatives of the second group are usually called slugs. Land snails have a three-centimeter shell. And the slugs are about 7 cm long.

All snails have one large leg located on the underside. These creatures are equipped with one or two pairs of antennae, or horns. They have two eyes, which can be located both at the ends of the antennae and at their base, and a mouth. It often expands into a tube, at the end of which are small sharp teeth, with which the snail can scrape off parts of plants.

Some snails eat animal food. The oyster borer, for example, the yellow-shelled sea snail, bores through the oyster shell and feeds on its flesh.

Snails and slugs breathe either with one lung or with gills. Those shells, which are often beautifully shaped, are distinguished by the mantle. They are usually spiral coils that appear as the animal grows.

Most snails lay eggs, but in some species, young are born by live birth. Snails and slugs leave a wet, shiny trail behind them. This allows them to walk and stay wet. This mucus, drying up, clogs the sink in winter. Snails hibernate in cracks or pits.

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 ... >>

Rugged smartphone Dewalt MD501 21.04.2016

Dewalt, a company known for its power tools, decided to try its hand at the smartphone market. Focusing on the already existing audience, the manufacturer has released a secure device MD501.

The novelty belongs to the class of secure smartphones that are really focused on use in difficult conditions. Here and protection against water (IP68), and the certificate MIL-STD-810G, which implies the ability to withstand drops from a height of up to 2 m, and the ability to withstand temperatures from -20 ° C to 60 ° C. Also, a five-inch screen with a resolution of 1280 x 720 pixels can be used with gloves.

Unlike many other similar smartphones, it is based on a budget, but still quite up-to-date MediaTek MT6735 SoC, supplemented with 2 GB of RAM and 16 GB of flash memory. That is, there will be no problems with performance in normal tasks. In addition, the novelty is equipped with cameras with a resolution of 13 and 5 megapixels, a microSD card slot, an NFC module, a 3950 mAh battery and supports wireless charging (Qi). The latest technology, by the way, is very useful just for this kind of devices. It relieves the user of the need to clean and wash the device before charging after a hard day for him and his device.

The dimensions of the MD501 are 156 x 82 x 14 mm and weigh 245 g. The cost of the novelty is about $545.
