Wireless speaker Huawei Sound Joy

27.02.2022

Huawei has launched the Sound Joy wireless speaker. It was developed jointly with the French company Devialet, which is one of the three largest world manufacturers of audio equipment.

The device has an elongated cylindrical shape and a case made of dense fabric with IP67 protection.

The device has four speakers. They can reproduce 79 dBA sound at a distance of 2 meters.

The speaker works via Bluetooth 5.2 and supports AAC and SBC codecs. The Sound Joy is powered by an 8800 mAh battery. It will last up to 26 hours of battery life.

There is support for 40-watt charging (10 minutes gives 1 hour of work). The column also received a button to launch the voice assistant and a number of smart functions.

The price of the novelty is 149 US dollars.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Night milk is healing 04.07.2005

Finnish dairy farms are producing a new product: night milk.

It turns out that if you milk a cow at night or in the morning, but in a darkened room, the milk contains 10 times more melatonin, the sleep hormone, than in ordinary morning, afternoon or evening milk. Melatonin is also produced in the human body, but with age and under the influence of stress, its secretion is greatly reduced. Therefore, drinking a glass or two of nightly milk before bed is recommended for all older people and those who find it difficult to fall asleep.

The novelty is in great demand in Finland. Hundreds of farms have switched to night milking, especially since the new sort of milk is noticeably more expensive than usual. In addition, physiologists have found that night milking increases the fertility of cows.

But in Switzerland, where a farmer tried to take advantage of the Finnish experience, night milk was banned shortly after it appeared on store shelves. The reason is the strict Swiss laws on food, drugs and dietary supplements. A food product cannot be claimed as a remedy for disease or a means of preventing them, and even a mild form of insomnia is considered a disease by law.

High levels of melatonin should not be reported on milk bottles, as melatonin is a hormone, hence a drug. Perhaps later in Switzerland they will be allowed to sell night milk in pharmacies.
