Gaming mechanical keyboards

16.03.2014

Razer announced the development of "the world's first mechanical keys designed for game control." The presented hardware solution is called Razer Mechanical Switch.

According to Razer, conventional mechanical keys are designed primarily for typing. That is why the company decided to start development from scratch in order to find the optimal design that is ideal for games. The result is Razer Mechanical Switches, which provide "more precise control than traditional mechanical switches."

It is noted that the Razer Mechanical Switches are manufactured using ultra-precise manufacturing technology. In addition, gold-plated contact elements are used. All this guarantees a very high durability - up to 60 million operations.

The new keys are available in Green and Orange. In the first case, the pressing force is 50 g and a sound response is provided. The Orange variant is silent, with a pressing force of 45g.

The Razer Mechanical Switch is manufactured by a third party, but Razer controls the process. The new mechanical switches are already being used on BlackWidow keyboards. The technology is also available to third-party computer peripheral manufacturers.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

New type of biomolecule discovered 25.05.2021

Biologists are fairly well versed in the basic molecular building blocks that make up living organisms. They have carbohydrates (such as starch), lipids (fats), nucleic acids (DNA), and proteins (muscles). They are divided into subtypes; for example, cellulose and sugars are carbohydrates. In addition, there are combinations between these groups, for example, various sugars combine with lipids in red blood cells to determine blood groups.

Glycans are chains of sugar molecules that can attach to fats and proteins in a process called glycosylation, helping them move through the cell or fold into the correct shapes. They are involved in many fundamental processes of biology, from embryonic development to pathogen recognition.

But now, researchers led by biochemist Ryan Flynn, who works at Boston Children's Hospital, have found that glycans can also attach to non-coding RNAs. They established this by tagging glycol molecules with sialic acid in laboratory cells and extracting the RNA from them. Some of the RNAs had a sugar coating labeled with sialic acid.

This was a surprise because previously it was believed that RNA functions only inside cells - in their nuclei and fluid, while glycans are usually separated from them by membranes in the cell organelles or on its surface.

The team found glycoRNA in every cell tested - in humans, mice, hamsters and zebrafish - species separated by hundreds of millions of years of evolution. This suggests that glycoRNA molecules may have some important biological function that persists throughout life on Earth.

By comparing the RNA regions of glycoRNAs with known databases, Flynn and colleagues found that some of them corresponded to RNAs associated with various autoimmune diseases.

It was previously thought that these RNA fragments were largely inaccessible to the immune system because they were hidden inside cells and released only when they died. But now glycoRNAs are found to be on the surface of the cell, just like proteins and lipids. This means that glycoRNAs can directly participate in intercellular communication, in parallel with other cell surface biomolecules such as glycoproteins/lipids, but with different dynamics, stability or configurations.

However, the ability of glycans to bind directly to RNA seems unlikely. Scientists suspect that there is a third, very small molecule in glycoRNA that acts as a glue.
