Where did the custom of drinking coffee come from in Europe?

From the Turks. After the siege of Vienna and the victory over the Turkish troops, the inhabitants got a bag of coffee beans as a trophy. The enterprising Polish nobleman Franz Georg Kolczycki opened the first coffee house in Vienna in 1683, where he served coffee with milk. In the future, this custom spread throughout Europe.

And the birthplace of coffee trees is the mountainous region of Kaffa in Ethiopia. Coffee beans are the seeds of a cherry-like fruit.

Which insect lives the longest?

For some reason, nature gave insects a very short lifespan compared to other living creatures that inhabit the Earth. But among the many insects there is one that enjoys life longer than many inhabitants of the animal world. Such an insect is one of the varieties of cicada, living for 17 years! No other insect, with the exception of only the termite queen, can even come close to this lifespan limit.

However, it is unlikely that other insects should envy the cicada, because for all 17 years it sleeps underground, after which it comes out into the light to live another 5 weeks and die. Why nature took these 17 years to develop such a tiny insect, no one knows. It is only known that the cicada lays its eggs on the branches of trees.

Only after hatching, small cicadas fall down and burrow into the ground, attaching to the roots. In this position, these pupae remain motionless for the next 17 years, feeding on the juice of the roots.

After this period, some unknown force makes them come out into the light. They climb the tree, their shell opens and a mature cicada emerges from it. By the way, the piercing sound that you sometimes heard outside the city is made by a male cicada. The male cicada has small cymbals that he tirelessly makes vibrate with his muscles. Scientists claim that the cicada's organ that produces this sound is the most complex "musical" organ known in nature.

There are over 800 varieties of cicadas, but the long-lived cicada is found only in the United States. Most cicadas live for about two years.

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 ... >>

Not all carrots are equally healthy 26.04.2024

Carrots have long been recognized as one of the healthiest foods due to their beta-carotene content, a substance that is converted into vitamin A, which is essential for maintaining vision and cardiovascular health. However, recent research shows that not all people benefit equally from eating carrots due to genetic differences.

Scientists at the University of Illinois studied the effects of beta-carotene on cardiovascular health, finding that its effectiveness depends on each person's genetic makeup. It turns out that the activity of the enzyme that converts beta-carotene into vitamin A varies between individuals, which determines how efficiently the body uses it.

During the study, scientists analyzed blood samples and DNA from more than 700 healthy young people. They found a correlation between enzyme activity and levels of "bad" cholesterol, and also found that genetic variations that affect enzyme activity are associated with blood cholesterol levels.

Experiments on mice confirmed the connection between beta-carotene levels and cholesterol deposits in blood vessels. High levels of vitamin A in the body actually reduced the risk of fatty plaque forming in the arteries.

It is important to note that approximately half of people have a genetically reduced activity of the enzyme responsible for converting beta-carotene into vitamin A. For them, eating carrots may be less effective, and it is recommended to look at other sources of vitamins, such as milk and cottage cheese.

Scientific work highlights the importance of taking genetic factors into account when assessing the health benefits of foods. The finding that the effectiveness of beta-carotene depends on the activity of a specific enzyme opens up new prospects for individualizing dietary recommendations and developing personalized approaches to maintaining cardiovascular health.
