How many miles does a person walk in their lifetime?

On average, a person walks and runs 160000 kilometers - four times more than the length of the earth's equator.

While walking, the load on the legs can be twice the weight of a person, and while jogging ("jogging") - 4-5 times.

How is humidity measured?

Moisture in the atmosphere causes clouds, fog, rain, snow, and warm, clear days. The atmosphere contains moisture in various forms: water vapor, liquid water, or frozen water. A hot, humid day differs from a hot, dry day only in the presence of water vapor in the atmosphere. The presence of water vapor in the atmosphere is called humidity. When we say "80% relative humidity" we mean that the air contains 80% of the amount of water vapor it can hold.

When air has 100 percent relative humidity, it contains as much water vapor as possible and is called saturated air. Warm air can hold more water vapor than cold air. An instrument used to measure the amount of water vapor in the air is called a hydrometer. The most accurate way is to compare dry and wet bulb readings. Two thermometers are mounted side by side on the same base. The surface of one is covered with a rough, wet cloth that can retain moisture. The surface of the second thermometer remains free and dry. Evaporation of water from an object cools it.

If the air contains a lot of water vapor, the moisture from the wet bulb evaporates slowly and it does not show a strong drop in temperature. If the air is dry, the moisture from the wet bulb evaporates quickly and the wet bulb reads a much lower temperature than the dry bulb.

Relative humidity can be determined by comparing two temperatures. There are other types of hydrometers that use the movement of air, chemicals, to measure the rise or fall in air humidity.

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 ... >>

Husky blue eyes revealed 10.10.2018

Geneticists from the company Embark Veterinary (USA) tested the DNA of more than three thousand dogs, including Siberian Huskies, as well as dogs of other breeds with blue and brown eyes. The results showed that all blue-eyed dogs are united by a mutation in the PMEL17 gene. At the same time, another anomaly is observed in the husky - in the ALX4 gene. Further studies showed that one section in the vicinity of the ALX4 gene doubled and became longer by about 100 thousand nucleotides - the "building blocks" of DNA.

The site in which the “failure” occurred is responsible for the activity of the MITF gene associated with the work of melanocyte pigment cells. These cells determine the color of the eyes, and in humans also the color of the hair and skin. The disruption in this area caused ALX4 to malfunction, causing more light pigment molecules to appear in the Siberian Husky's iris.

According to study authors Adam Boyko and Aaron Sams, this is the first study of the genome of animals - not humans - in the field of consumer genomics. This industry allows using a DNA test to determine not only the origin of our ancestors, but also to obtain information about the phenotype: for example, lifestyle habits, habits and other characteristics.
