What does the liver do?

Every time we study some organ of the human body, its structure and work, it can seem to us almost a miracle. The liver is no exception. This is the largest gland in the body and, apart from the brain, the heaviest organ. The average weight of a human liver is about one kilogram.

The liver has to be that big to do its job. It produces digestive juices and is a filter in which all food coming from the intestines (except fats) undergoes chemical processing. The liver is like a blood-filled sponge that absorbs food digested in the intestines.

With food in the liver, what can be called "restructuring" occurs. The foreign protein is converted into human protein. In addition, the liver cleanses food of poisons. When nicotine and caffeine enter the body, the liver converts these "poisons" into harmless compounds. Liver cells also destroy bacilli that can enter the body.

Since the liver is located between the intestines and the heart, it acts as a dam for the fluids we drink. If you drink large amounts of fluid, the liver will quickly enlarge. Liver cells produce a digestive fluid called bile. One of the functions of bile is to emulsify fats. In this case, large particles of fat contained in digested food break down into very small particles, which allows the body to absorb fats.

How did units of measurement come about?

Long before standard units of measure were established, man measured one thing by comparing it with another. It was most convenient to measure with your own body. For example, if a person wanted to measure the distance from his house to a neighboring one, he did it in steps.

The unit of measure was the stride length. To measure a room, a person put one foot in front of the other in turn. The distance was measured by the length of the foot (in English "foot"). Arms, hands and fingers were used to measure things like fabrics or clothes.

The units of measurement were the distance from the tip of the nose to the tip of the fingers of the outstretched hand, the distance from the tips of the fingers to the elbow, the distance from the thumb to the little finger in the splayed state, the width of the palm, the width of the thumb. The problem was that these sizes are different for everyone. The legs, arms, fingers of one person are shorter or longer than those of another. Therefore, it became necessary to establish standard units of measurement. And in the Middle Ages, the community of merchants agreed on units of measurement.

Later, such standards began to be approved by governments. There is currently an international agreement on standard units of measurement. Governments of different states agreed to use the same measures. Many governments have special bodies responsible for standards. In 1791, the metric system of measurement was invented in France, which is now in use in many countries. The United States, Canada, Australia, New Zealand and the United Kingdom are also gradually adopting the metric system.

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 ... >>

Shark warning system 10.08.2020

All living beings, during their biological life cycle, one way or another donate particles of their DNA to the environment - this process is especially easy to follow in the aquatic environment, where many underwater inhabitants spread their DNA through excrement, skin particles or other biological tissues. This type of DNA is called eDNA.

A joint team of specialists from several US universities decided to use this eDNA to compile a special alert system designed to protect vacationers on the coasts of the United States from the possible attack of great white sharks, which also donate some of their DNA to the aquatic environment and which, among other things, are a real threat to vacationers.

Specialists from the University of Santa Barbara in California turned to the so-called laboratory genetic analysis technique called PCR, which can identify and study specific biological markers of living creatures based on the studied tissues of these creatures. Similarly, the team of experts did the same with the tissues of the white shark, which is the most dangerous predator in some regions of the Pacific Ocean.

When a team of researchers compared these studied markers with some regions of the Pacific Ocean, near which tourists rest in order to establish whether there are sharks there. The team reports that these biological markers correlate with white shark DNA particles found in these regions, so experts have developed a whole system that allows predicting the potential appearance of white sharks in a particular region of the ocean, which allows time to ensure the safety of vacationers.

The presented development is really remarkable and very interesting also for the reason that it can also be embodied in the use of additional underwater drones that would collect the necessary information and which could update information regarding the current location of most white sharks. It also becomes part of the specialists' plan to improve their system, so it's worth waiting for the first results of its testing.
