Where did potatoes originate?

When we talk about potatoes, we think of Ireland. There is a reason for this. The potato has played an important role in the history of Ireland. Hundreds of years ago, the population of this country was largely dependent on the potato crop as their main food. And in 1846, the entire potato crop was destroyed, and more than 600 people died of starvation!

However, having become native in Ireland, the potato did not appear there. Her homeland is the highlands of Ecuador and Peru. Even today you can find wild potatoes there. When the Spaniards arrived in Peru, they discovered the potato and took it with them to Spain in the early XNUMXth century. From Spain, it spread throughout Europe and became very popular and loved.

Some believe that the Spaniards brought the potato first to North America. But there is evidence that it was brought to New Hampshire from Ireland in 1719. The potato belongs to the nightshade family. The potato is a thickened underground root. And the "eyes" of potatoes are underdeveloped kidneys.

But today's potato is very different from its South American ancestor. Changes have been made by various cultivation methods. Those who grew potatoes constantly worked on them in order to obtain certain qualities. We wanted to get potatoes that are fruitful, resistant to diseases, long-term storage, pleasant color and shades. Therefore, only those tubers that corresponded to all these qualities were selected for seeds.

Potatoes do not grow from seeds, but from "eyes" on tubers, which are buds. These buds grow into sprouts. Potatoes have white or purple sprouts. In height, it is from 30 to 90 cm. When the tops of the bush wither and dry out, the potatoes can be harvested. Potatoes are used for food, for the production of starch and for the production of alcohol.

Where is gold produced from sewage waste?

The gold content in the ash from the burning of dry sewage sludge in the Japanese city of Suwa is more than 50 times higher than that of the best gold mines. Experts explain this fact by the fact that there are many electronics factories in the city, in the production of which gold and gold-containing alloys are widely used. Installations for the extraction of the precious metal are already in operation.

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 ... >>

Nanowires three atoms in diameter 29.12.2016

A group of scientists from Stanford University and the Stanford Linear Accelerator Laboratory (SLAC) has discovered the possibility of using the smallest particles of diamonds - adamantanes (diamondoid) - conductive nanowires with a diameter of only three atoms. Moreover, each such wire is enclosed in a reliable shell of diamonds, which makes them strong enough and protected from short circuits with each other. Such nanowires can find applications in optoelectronics for data transmission, as a solution for generating energy from the sun or in other areas. For example, it is possible to produce fabric for clothes with sewn-in electronics or solar panels invisible to the eye.

The most important part of the development was such properties of the new material as self-assembly. According to scientists, nanowires are assembled like a LEGO constructor. The role of "cubes" with grooves and guides in the assembly of nanowires is played by the smallest particles of diamonds. By the way, the solution with diamond particles for experiments was obtained from oil produced in the state of Arkansas. The oil in this area has all the impurities necessary for growing "diamond" nanowires. But for the solution, it underwent a special cleaning, during which "cubes" of approximately the same size remained in the mixture.

In addition to adamantanes, each of which has one sulfur atom attached, a solution of copper sulfide was used to grow nanowires. In solution, the molecular lattice of adamantanes began to be affected by attractive forces in the form of van der Waals forces. Adamantanes began to stack one after another, involving copper atoms in the process, and the wires grew in one direction. Scientists have proven that this is a precisely controlled process, which allows us to talk about good prospects for development.

In addition to copper, experiments with the self-assembly of "three-atom" nanowires were carried out with cadmium, zinc, gold, and silver. Each of these or other materials gave the wires different and unique properties. The use of cadmium, for example, made it possible to give the wires the characteristics of LEDs. Other materials have promised to give nanowires the properties of piezocrystals, and this is the direct conversion of mechanical deformations into electricity (energy-producing fabric of a suit or sports uniform). Nanowires have many prospects. It would be nice to wait for commercial implementation.
