Which bird speaks best?

There are many birds that can be taught to say a few words. But real "talking" birds can learn to pronounce entire sentences!

The best "talking" birds are parrots, crows, mynas (talking starlings), jackdaws and some jays. Scientists agree that the African parrot and the Indian myna bird "talk" best of all.

Many people believe that a bird's ability to "talk" depends on the structure of its tongue. Parrots, for example, have large, thick tongues. But all the other "talking" birds have small tongues!

Do birds understand the words they say? Most biologists believe that birds do not understand what they are talking about, but can sometimes associate words with specific actions.

When did shoe stores use x-rays?

In 1927, a fluoroscope for shoe stores was patented, which entered American and European salons. The buyer had an x-ray of his feet, which made it very convenient to select shoes. However, after numerous complaints about damage to health from a shock dose of radiation (one woman even had her legs amputated), all the devices were withdrawn and destroyed.

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 ... >>

Reusable oil absorbing sponge 12.03.2017

Researchers at the Argonne National Laboratory have developed a "sponge" that sucks up 90 times its own weight in oil and can be used up to 100 times.

Oil spill cleanup is complex. There is a set of tools cleaners use to separate oil from water, but they are all slow or expensive, or both. The best way to clear the water of oil is to use a floating absorbent material called a sorbent boom that absorbs the oil. Depending on the material, absorbent boom can absorb from 3 to 70 times its weight.

The problem is that it can only be used once. Once the material absorbs enough oil, it must be removed from the water, which means that a large amount of sorbent material is required to clean up large oil spills.

The new material not only absorbs oil waste better, but it can also be reused. In tests, the "oil sponge" absorbed 90 times its own weight, after which it could simply be squeezed out and used again. Such material could significantly reduce the cost of cleaning up future oil spills.

The sponge is made of polyurethane foam coated with silicic acid, which attracts oil. The ratio of polyurethane and silicon hydrogen must be very accurate: if there is little silicon hydrogen, then the sponge will not absorb oil, and if there is a lot, it cannot be reused. So getting the exact ratio is quite difficult, and therefore such a sponge will be difficult to use in the open ocean, but in calmer coastal areas it is quite possible.
