Notebook HP Envy dv7

28.03.2013

Hewlett-Packard has released the Envy dv7 laptop, designed for use at home or in the office instead of a desktop computer. The first country where he appeared was Japan, but in the coming days he will reach Europe. The recommended retail price is $500 for the base package.

Of course, it's hard to imagine a $500 laptop that can replace a more or less expensive gaming desktop, but the Envy dv7 is quite capable. The manufacturer immediately noted that even in the basic configuration of this mobile PC there is an Intel Core i7-3630QM processor, the clock frequency of which in normal operation is 2,4 GHz for each of the four cores, and in turbo mode it rises to 3,4 GHz . It also has a built-in video card, which is activated only when the battery is low - in all other cases, instead of it, graphics are handled by a discrete NVIDIA GeForce GT650M adapter with its own memory.

The screen on the HP Envy dv7 laptop is quite large - 17,3 inches diagonally. True, he does not have support for Full HD resolution - the need to keep the computer in a certain price range affects. The maximum supported resolution is 1600x900 pixels.

The minimum configuration of the laptop, the one that costs $500, contains 4 GB of RAM and a 2,5-inch hard drive with 500 GB. More expensive models will reportedly get an SSD of unknown capacity. The laptop also received an optical drive with the ability to burn dual-layer DVDs. It does not work with Blu-ray format. The laptop comes preinstalled with Windows 8 operating system.

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 ... >>

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, ... >>

genetically modified opossum 04.08.2021

Scientists from the RIKEN Biosystems Dynamics Research Center (Japan) have carried out the world's first genetic editing of a marsupial. This study will allow us to better understand the unique genes that are present only in marsupials.

Genetically modified animals, especially mice and rats, are extremely important tools for the study of biological processes. Thus, scientists can silence a gene in order to establish its true function.

Marsupials have very unusual genetic characteristics not found in placental mammals. Scientists chose the possum for research because it is considered one of the most ancient living species. Its genome has already been fully sequenced, and the size and other properties are similar to those of mice and rats.

As part of the experiment, scientists injected a genome-editing solution into fertilized eggs of a female opossum. Then the eggs were transplanted to a surrogate mother. As a result, specialists managed to obtain the first genetically edited offspring.

Experts have investigated the gene responsible for the production of pigment for the body. When a gene is disrupted, the body does not produce enough pigment. So, some cubs born to a surrogate mother turned out to be albinos - this meant that the experts successfully influenced the gene. Albinos grew up and passed on the defective gene to the next generation.

Having tested the technology, scientists intend to conduct further experiments. Their data will be important for areas such as embryology, neuroscience, reproduction, immunogenetics, cancer biology, and even comparative evolution.
