When did you start milking cows?

Ancient manuscripts report that humans consumed milk and dairy products, and cows provided milk even before there were any manuscripts. In an ancient temple discovered near Babylon, they found wall paintings depicting the process of milking a cow.

It is believed that this temple is about five thousand years old. Nowadays, cows are milked on the right side, while earlier it was milked from behind. This man was sitting on a special chair, while others were pouring milk into a special vessel on the ground. Still others poured milk into large earthenware vessels. It seems that the process of milking a cow was well organized already five thousand years ago.

Today, milk is obtained mainly from cows and goats. But in other parts of the world, milk from other animals is also used. For example, in Asia it is a camel, a horse or a yak. Eskimos and Laplanders drink reindeer milk. Buffaloes provide milk in India and Central Asia. Sheep are milked in Europe and Asia.

Milk contains several hundred different chemical elements, but most of all it contains calcium, phosphorus and protein. Since milk is easily digested, calcium, phosphorus and other minerals are quickly and efficiently absorbed by the body. Milk sugar (lactose) and the main milk protein (casein) are found only in milk.

What are freckles?

To understand what freckles are and how they appear, we must understand what gives skin its color in the first place.

The most important pigment in the formation of skin color is melanin. We can say that the difference in skin colors of different races depends entirely on the amount of melanin.

By the way, in the lower forms of life, it is melanin that makes it possible for some fish and lizards to change their color. Its most important function for humans, besides color management, is to protect us from the harmful effects of too much exposure.

Melanin is produced by a network of special cells that are scattered throughout the lower layer of the epidermis - the thin outer part of our skin. These cells are called "melanocytes". Now we come to the question: what are freckles? So, freckles are just clusters of melanocytes in specks. This is why freckles have such a brownish color, the color of melanin pigment. Why do some people have freckles and others don't? The reason is heredity. Our parents decide for us whether we get freckles!

The color of freckles (actually the color of the melanin in them) can range from light tan to dark brown, depending on sun exposure and heat. Not only can sunlight darken freckles, it also produces new melanin.

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 ... >>

Google patents augmented reality watch 09.10.2012

The popularization of "smart" watches began quite recently, and so far there are still quite a few players in this segment of the market. However, the American corporation Google also showed interest in this industry and received a patent for the use of augmented reality technology in watches.

The search giant filed a request for a patent about a year ago, and this week it was approved by the US Trademark and Patent Office (USTPO). The document states that Google's SmartWatch is equipped with a camera, a flip-down transparent cover-screen and a built-in Wi-Fi module for connecting to wireless networks. The device works as follows: when the user flips the transparent cover, it will turn into a screen that will display information about the object at which the camera built into the watch is directed. In addition, using the gadget, the user will also be able to view notifications and use Google services.

In general, the device described in the patent is much more advanced than the smart watches from Sony or Pebble already on the market, and therefore it is interesting how exactly Google is going to implement its idea. Currently, nothing is known about any prototypes or prototypes, and therefore if the company actually decides to turn its idea into a real product, then the appearance on the shelves of Google SmartWatch stores is unlikely to happen soon.
