Which bird lays the smallest eggs compared to its own size?

Ostrich.

As the largest single cell in nature, the ostrich egg makes up less than 1,5% of the mother's weight. The weight of a wren egg, for example, is equal to 13% of the bird's own weight. The largest egg in relation to the size of the bird belongs to the female small gray kiwi. The weight of her egg reaches 26% of the mother's weight - it's the same as if an ordinary woman gave birth to a six-year-old child.

An ostrich's egg weighs as much as twenty-four hen's; it takes three-quarters of an hour to boil it soft-boiled. Queen Victoria ate a delicacy for breakfast with pleasure, assuring that she had never eaten anything tastier.

The largest egg ever laid by a living creature, including dinosaurs, belonged to epiornis, a giant ostrich-like bird that lived in Madagascar and was exterminated in 1700. The egg was ten times the size of an ostrich, nine liters in volume and equivalent to 180 chickens.

It is believed that it was epiornis (Aepyornis maximus), or "elephant bird", that became the prototype of the ferocious bird Rukh, with which Sinbad fought in the Thousand and One Nights.

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 ... >>

Random news from the Archive Flash Memory Made from Organic Materials 10.11.2014 The Japanese Institute of Physical and Chemical Research RIKEN experimentally proved the possibility of creating a high-density non-volatile memory based on organic materials. "Organic" is used in electronic circuits is not the first time. Many have heard of Samsung's AMOLED displays and simply OLED displays. Also, transistors based on organic materials are used in the production of advanced solar panels. But one more effect of organic materials is known - photochromic, which has not yet found wide application in electronics (chameleon glasses do not count). This effect lies in the fact that under the influence of ultraviolet radiation, molecules from certain compounds become colored from transparent: yellow, blue, red. This effect is reversible - irradiation with a visible light source returns transparency to the molecules. As long as the re-exposure has not occurred, the color change of the molecules does not occur - they retain their state without the obligatory support of nutrition (without illumination). Why not memory? The effect of photochromism has been studied for a long time. The main task was to develop a technology that could turn the "broth" of the chemical composition of dissimilar substances into an ordered structure, similar to an array of SRAM or DRAM. In this case, the molecules must reproduce the semblance of a memory array on something suitable for the further creation of an electronic circuit. For example - on a copper substrate. At the RIKEN Institute, based on the chemical mechanisms of self-assembly of molecular structures from diarylethylene derivatives, they created a similar technology and proved its efficiency in practice. On the slide below, on the right, you can see a model of an ordered molecular assembly of repeating elements, and on the right, an image of a real sample made using a scanning tunneling microscope. According to the developers, the molecular structure allows you to record data with a density of over 1 Tbit/square inch. This is higher than the recording capability of traditional means. True, while RIKEN technology leaves the laboratory, modern technologies can advance far and it is not yet certain which of them will be truly breakthrough.
