What is mold?

You may have observed the following phenomenon. You left a piece of bread in a wet plastic bag in the kitchen and after a couple of days, you stumble upon it and find it covered in a green, "fluffy" coating. In such cases, the bread is said to be "moldy" or moldy.

Where did this mold come from, and what does it represent? First of all, it should be noted that spores of green and black mold are present in the air almost everywhere. If they manage to get into favorable conditions and gain access to nutrients, then they begin to multiply at a rapid pace.

If we look at the web-like mold under a microscope, we can find that it consists of many long, colorless threads, on which there are branches of two types. Long branches have small black balls containing spores at the end. Other, shorter ones, penetrate deep into the surface (in our case, a piece of bread) on which the mold is located. They serve the mold in the same way that the roots do for other plants, as they not only help it to gain a foothold in one place, but also absorb the nutrients necessary for its growth. They are present in any type of mold.

This means, in other words, that the mold is not able to produce food for itself in the same way that green plants do, and therefore scientists classify it as a simple fungal parasitic plant.

Most people in life have to deal with mainly two types of mold: black and green. As you might guess, these names correspond to the color of these varieties. The ubiquity of mold, as already mentioned, is primarily due to the huge number of its spores in the air around us. Therefore, one has only to forget fresh food, canned food, fruits and even a leather product for one or two days in a warm, damp room, as they are immediately "attacked" by spores, and a colony of mold fungi grows on the object.

The green mold that appears on bread is extremely similar to another mold that lives in the soil and is the raw material for the production of the well-known drug - penicillin.

Random interesting fact from the Great Encyclopedia:

Why did pilots at the dawn of the development of aviation massively wear silk scarves?

In the early days of aviation, pilots didn't have a lot of instruments to track enemies, so they constantly had to turn their heads, looking for enemy aircraft. To prevent the neck from rubbing against the collar, silk scarves were introduced into the uniforms of the pilots. Many pilots wear scarves to this day, although they no longer have a functional purpose.

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 ... >>

Europe is warming faster than other continents 23.04.2024

Europe is facing dramatic climate change, and the consequences are becoming more and more acute. Data from two leading climate monitoring organizations suggests the continent is warming significantly faster than the global average.

A joint report by the UN World Meteorological Organization and EU climate agency Copernicus on the state of the climate in Europe over the past year has revealed that the continent is experiencing a rise in temperatures double the global average.

An increase in average temperatures of 2,3 degrees Celsius above pre-industrial levels puts Europe in a difficult position. This rise in temperature is 1,3 degrees Celsius above the global average and is no longer just a statistic, but a fact that is having a major impact on people's lives.

Heat-related deaths are increasing across the continent, highlighting the importance of adapting to new climate conditions. The dire consequences of extreme weather conditions such as storms, floods and wildfires are becoming increasingly visible and require greater efforts to prevent their devastating impact.

However, despite all the challenges, there is an opportunity for Europe to develop strategies to accelerate the transition to renewable energy sources. Successful measures in the field of renewable energy are already showing their effectiveness, and further development in this direction can help mitigate the negative impacts of climate change.

Europe faces real challenges from climate change and it is important to take effective action to mitigate its negative impacts. Despite the challenges, the opportunity to transition to renewable energy offers the continent a chance to move forward and build a more sustainable future.
