The fastest computer mouse

08.02.2021

Razer has released a mouse for gamers with record performance. The Razer Viper 8K is the fastest mouse on the market, according to the company.

Created by an American company, the device operates at a frequency of 8000 hertz, that is, it receives data from the sensor eight thousand times per second. This is about eight times faster than the sensor frequency in conventional computer mice. The increase in speed was due to HyperPolling technology, which collects data from an optical sensor and transfers it to a computer via a high-speed USB microcontroller.

Optical sensor latency has been reduced from 1 millisecond to 1/8 millisecond. Razer says that this speed is impossible to assess with the naked eye, but you can notice smoother cursor movement and the absence of microlags in operation.

The rest of the Razer Viper 8K has not changed compared to the previous version of the device. The model received the latest generation of optical switches, the latest Focus + optical sensor, lightweight body, SpeedFlex wire, eight programmable buttons, five user profiles.

The cost of the Razer Viper 8K will also remain at the level of the previous model. You can buy a mouse for gamers for $80.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Tasmanian Devil's Milk Contains Powerful Antibiotics 25.10.2016

Scientists from the University of Sydney (Australia) have synthesized a protein that mimics the milk protein of the Tasmanian devil, which has antibiotic properties. At the same time, the substance is active even against bacteria that are resistant to traditional antibiotics.

The study showed that the substance copes with such pathogens of dangerous infections as Staphylococcus aureus and Enterococcus aureus. This protein, the structure of which scientists "peeped" from the Australian marsupial, was named cathelycidin.

Interest in the Tasmanian devil is due to the fact that these animals successfully carry young in bags, despite an unsafe environment with a lot of bacteria. Since the immune system of these animals is quite primitive, scientists began to look for an answer in a different direction. And they found it by studying the characteristics of the milk of a female Tasmanian devil. It turned out that a special protein found in milk is absent in other mammals or is present, but in small quantities.

The authors of the study hope that their discovery will allow the creation of new drugs that are effective against the so-called superbugs that do not respond to existing antibiotics. The problem of antibiotic resistance has been rapidly exacerbated in recent decades; according to WHO estimates, about 700 patients per year die from diseases caused by such bacteria, and this figure is constantly growing.
