What is the function of goose skin?

The reflex that causes goosebumps is inherited from animals. The muscles of the hair follicles contract and lift the hairs - as a result, the animal's hair stands on end. When reacting to cold, this helps to retain body heat longer, when reacting to danger, it makes the beast more massive and intimidating. In humans, in the process of evolution, there is little hair left on the body, and this reflex has no practical meaning.

Why are pocket knives called penknives?

Steel fountain pens became widely used in the middle of the 19th century, and before that they wrote mainly with goose quills. Such feathers needed to be sharpened periodically, which was called sharpening. Accordingly, a special knife for this procedure was called a penknife. Later, the word "pencil" was applied to all pocket knives.

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 ... >>

Philips smart door handle 21.01.2024

Philips Corporation has announced its latest development in home security - a smart door handle with innovative palm recognition technology. This cutting-edge device features a unique biometric system that identifies users by the vein pattern of their palms, reminiscent of the technology previously introduced in the LG G8 smartphone.

Philips' new pen with palm recognition technology represents a significant step forward in home security, promising to improve user safety and convenience.

The special feature of this lock is its folding sensor, which is activated when a hand approaches. Scanning a clear map of the veins in the user's palm allows the built-in sensors to easily and unobstructedly unlock the door when the hand approaches.

Philips claims that this smart door handle with palm recognition can completely replace traditional door locks. It provides control through a special application and voice commands using assistants such as Google Assistant.

The $360 Palm Recognition Smart Deadbolt is scheduled to launch in the first half of 2024, bringing a new level of security and convenience to home access.
