OWC Accelsior S - PCIe-SATA expansion card

26.05.2015

The Accelsior S expansion card has appeared in the Other World Computing (OWC) range. It allows you to connect 2,5-inch SATA hard drives and solid-state drives to the PCIe 2.0 x2 bus, that is, it plays the role of a bridge. The board has an Asmedia 1062 controller.

The Accelsior S is said to deliver transfer speeds of up to 550MB/s read and 530MB/s write (actual speeds vary by drive). The product is very easy to install and use because it does not require drivers or other software.

The price of the novelty is about $58. Sales have already begun.

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, ... >>

Sweet lovers are prone to alcoholism 17.07.2013

Studies have shown that there is a direct link between sugar cravings and addiction to alcoholism. In addition, researchers at the Indiana University School of Medicine have found, using functional magnetic resonance imaging (MRI), that alcoholism is associated with the orbitofrontal region of the brain, which is also responsible for the response to sweet tastes. An analysis of the functioning of this part of the brain can serve as a marker of an increased risk of alcohol dependence.

Previously, scientists have found that animals with an addiction to alcohol prefer to drink sweet water. But a new study has shown that there is an inverse relationship - animals that like sweets drink more alcohol.

Finding a link between sugar cravings and alcohol in humans requires additional factors to be taken into account, but some scientific research already shows that alcoholics or non-alcoholics with a history of alcoholism have a preference for sugary foods.

For the study, scientists chose 12 men and 4 women. All participants in the experiment were young (26 years old) and healthy. Each of them underwent a taste test - they checked their reaction to eating sweet food using MRI. In addition, the scientists learned about the alcohol addiction of the subjects - the amount of alcohol they drank, the frequency of drinking, etc. Thus, the researchers wanted to determine the area of the brain that is responsible for the perception of sweets, and also tried to find out if this brain reaction is similar to the reaction when drinking alcohol.

The trend was that those who drank more alcohol (meaning the amount of alcohol they drank in one evening) had stronger responses to sugary water in the left orbitofrontal region of the brain. In addition, these same people in their subjective assessments noted sweet water as preferable.

Scientists believe that more research is needed on the relationship between sugar preference and alcohol addiction. It is known that addiction to alcohol is caused by several factors, but it is important to find a specific part of the brain that forms a kind of "encouraging" signal. What's more, people's sugar cravings, their brain response to sweets, can serve as a marker for identifying people at risk of developing alcoholism.
