Who is a narwhal?

Narwhal is one of the most interesting members of the cetacean family. Many of us believe that there is only one type of whale, but in fact there are several varieties of them. The most interesting of them are the so-called toothed whales. Toothed whales prey on fish and cephalopods and feed mainly on them.

Sperm whales are the largest of the toothed whales. They reach twenty meters in length, and their distinctive feature is a massive head.

Another representative of this suborder is the bottlenose, so named because of the strange bone growths on the sides of the head. Narwhal is also a toothed whale. It lives mostly in arctic waters and has something that no other whale has: the male narwhal has a long bone tusk growing on the left side of its mouth that sticks out like a sword!

 Random interesting fact from the Great Encyclopedia:

How is the human eye arranged and why do we distinguish colors?

The beam reflected from the object is focused by the lens on the retina of the eye, forming an inverted image of the object. There are light-sensitive cells on the retina: approximately 110-125 million "rods" that form a black and white image, and about 6 million "cones" responsible for color perception.

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 ... >>

A simple way to extract uranium from seawater 17.10.2023

An international scientific team has presented a new, simple and effective method for extracting uranium from the waters of the World Ocean. The complex material used is highly selective towards uranium and does not interact with other molecules and metals in solution. This technology could be a promising alternative method for extracting a key component for nuclear power plants and treating nuclear reactor wastewater.

Uranium is an extremely valuable mineral that provides fuel for nuclear reactors around the world. In the oceans, the concentration of uranium is thousands of times higher than its reserves in the depths, but it is present in water in low concentrations (3,3 μg/l), which makes its extraction difficult. The main problem is the presence of other substances such as sodium, iron and calcium in much higher quantities in seawater.

Engineers used layered double hydroxides as the basis for their technology. This composite material is a layered structure with positively charged layers separated by negatively charged ions dissolved in water. These materials are already widely used to extract metals from liquids, are relatively simple to produce and can be easily modified.

To make the hydroxides selectively sensitive to uranium, the researchers introduced various lanthanide dopants such as neodymium, europium and terbium. Studies have shown that layered double hydroxides with the addition of neodymium interact with uranium 10 times more efficiently than with other metals dissolved in seawater.

The method also benefits from cost-effectiveness because the materials used in the process are fairly easy to produce and inexpensive, making them an attractive choice for large-scale uranium mining, according to Carolan Veliszek, one of the study's co-authors.
