Razer Blade Compact Gaming Laptop

23.05.2018

Razer has unveiled its new gaming laptop Razer Blade, which the manufacturer called the world's most compact such device. The model received a 15,6-inch IPS-display with a resolution of Full HD 1920x1080 pixels with a frame rate of 60 or 144 Hz or a resolution of 4K 3840x2160 pixels with a frame rate of 60 Hz.

The novelty is based on a powerful six-core processor Intel Core i7-8750H clocked at 2,2-4,1 GHz. Two graphics cards to choose from: Nvidia GTX 1060 Max-Q with 6 GB of memory or GTX 1070 Max-Q with 8 GB of memory. RAM: 16-32 GB DDR4-2667 MHz. Persistent storage - SSD PCIe NVMe module with capacities ranging from 512 GB to 2 TB.

The GTX 1060 variant can be purchased starting at $1900, while the GTX 1070 version starts at $2400.

Notebook dimensions are 355x235x16,8-17,3 mm, weight - 2,07 - 2,15 kg, depending on configuration.

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. ... >>

While playing, the brains of parents and babies are synchronized 14.01.2020

During the game of babies aged 9-15 months and their parents, brain activity is synchronized. This happens in the prefrontal cortex. This is not observed between children and adults who simply sit side by side and read a book aloud, and synchronization itself seems to be at the heart of learning through communication.

The ability to communicate is formed in a person even in infancy: at a very early age, a child, for example, learns what will happen when he starts crying or screaming, and then he can use this as a way to get attention from a parent. Of course, this process is accompanied by the formation of strong neural connections, but this process itself has been studied only superficially.

Scientists led by Elise Piazza from Princeton University decided to test one key aspect of the formation of neural connections - the synchronization of brain activity during communication. Previously, researchers have shown that adult brain activity is synchronized during conversation, and in the new work, scientists decided to test whether the same thing happens during play - the main way of communication between infants and their parents.

The study involved 18 children aged 9-15 months and their parents. The brain activity of the participants was assessed using functional spectroscopy in the near infrared region (fNIKS) - this method allows you to visualize brain activity by blood flowing to active areas, since hemoglobin in it absorbs infrared radiation well.

During the experiment, the children played toys with their parents, listened to how they read books and talk. The brain activity of the infants was compared with the activity of the brain of its parent, and in the control condition - with the experimenter, who, being next to the child, but not looking at him, read a book to another person.

It turned out that during the game between the activity of the brain of a child and a parent, there is more synchronization than between the brain of a child and an adult when he just reads a book to him and does not look at him. Activity correlated most in the prefrontal cortex, but also in the parietal zone. In addition, synchronization was higher if the child and adult were looking at the same object.
