Synthetic brain

06.03.2019

According to scientists at the University of California, the creation of a "synthetic brain" is not far off. The first important step towards this has been taken. The fact that a group of scientists began to create a "synthetic brain" was announced in 2012. Its members intend to make a thinking machine with physical intelligence.

In the process of research, experts have found that a network of closely spaced copper columns can grow a nanowire if it is specially treated with silver nitrate.

The wires diverge, as if in random directions. However, they are very similar to the crossing neurons of the brain. At the same time, nanowires organize themselves. At the atomic level, they resemble synapses. These are the points at which two neurons can send signals to one another. Such a reaction is shown by an MRI of the brain when the preservation of memories is displayed there.

When an electrical signal was sent through the resulting network, the nanowires demonstrated an independent organization of information in the likeness of the human brain. That is, when they are networked, they begin to communicate with each other. In a certain sense, this system has already become "alive", showing the interaction.

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. ... >>

Silicon clock, not electronic 08.07.2006

Silicon microcircuits are used in electronic digital watches, and their very pulsating "heart" - a quartz crystal - is silicon dioxide.

And recently, the well-known Swiss company "Patek Philippe" has found the use of silicon in high-class mechanical watches. Using the photolithography method, which is used in the manufacture of microcircuits, Swiss watchmakers cut out the thinnest spiral from a silicon plate with a thickness of just over a tenth of a millimeter. She replaced the steel hair of the balance in the watches of the latest model.

Unlike steel, silicon is non-magnetic, so the new watch is not afraid of magnetic fields. The material is also insensitive to temperature changes. But the main thing is that the silicon spiral contracts and expands much more evenly than the steel one, which made it possible to increase the accuracy of the stroke.

The first batch of dozens of silicon watches priced at $20 went on sale in Basel in the spring of 2006.
