Why do some people's hair curl?

We are all very curious to know everything about hair. Why are they this color? Why does hair turn gray? Why do some people have curly hair? Science has not yet given all the answers regarding our hair, but let's talk about what is already known.

Some types of cells that live in hair roots contain pigment. These cells are able to multiply, and the newly formed cells rise up along with the growing hair shaft and then die. The pigment granules in them with all shades of brown: from reddish to dark brown - remain on the hair.

The horny substance that makes up the hair is yellow in color. This substance and pigment granules are mixed. Hair color is determined by the result of this mixing. The hair of different people also differ in structure. If we cut a hair and examine its section under a microscope, we will see that it has a well-defined shape. It can be round, flat, oval, elliptical and even semi-elliptical and oblong. The shape largely determines whether the hair will curl or not.

The more oblong the section of the hair, the more it curls. The rounder it is, the stiffer and straighter the hair. Elliptical and semi-elliptical hair is usually short and curly, like a lamb. This is typical for people of the Negroid race. The direct opposite of them is hair with a round section. They are usually straight, long and coarse. Hair with an oval section is usually wavy and curly, or soft and silky.

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 ... >>

Motorola Project Ara Modular Smartphone Platform 30.10.2013

Motorola Mobility's advanced technology division has unveiled a project codenamed Ara to create a universal platform for building modular smartphones.

The idea is to give users the freedom to choose components for their cell phones, replace them as needed, and change the functionality of the devices.

Work on the project has been going on for more than a year. The concept of modular smartphones involves the use of the so-called endoskeleton - the basis on which a wide variety of electronic modules will be placed. As planned by Motorola, users will be able to choose the processor, display and / or keyboard they need, the camera unit and battery, the required set of sensors, etc. As the device is used, its owners will be able to upgrade aging components without having to buy a new smartphone entirely.

The ultimate goal of Motorola Mobility is to create a free and open ecosystem where all interested developers and manufacturers can release functional hardware modules for smartphones of any class.
