#news high technology 257 | non-flammable wood and beer on Mars

Every Monday in the new issue of “News of high technologies” we summarize the results of the last week, talking about some of the most important events, the key discoveries and inventions. This time we will talk about non-combustible wood, beer on Mars and more!

1. This week, Intel announced three new vulnerabilities of their processors. According to the American company, these vulnerabilities can be exploited to gain access to some data stored in the computer memory. Under the threat of a processor Core and Xeon.

The company has already released an update that closes the vulnerability was found. Otherwise, she wouldn’t openly share information about them. Released update reduces the risk of attacks for personal computers and data centers that use Intel processors.

We can expect increased attention from Intel to the security of their chips after a group of researchers found them seriously flawed. In January, it was found a vulnerability that allowed hackers to steal sensitive information from virtually any device equipped with a chip from Intel, AMD, or ARM Holdings.

2. Wood is a good building and decorative material, but its use is associated with weight the most enjoyable moments since the cost and harm to the environment due to massive deforestation to a high fire hazard. However, a group of Chinese researchers have created a material that solves all of the above problems.

“Synthetic” wood look and at the microscopic level resembles the fiber of this tree, having similar properties: strength, ability to retain heat and so forth, however, plus it is resistant to high temperatures, acids the Main material is synthetic polymer that kristallizuetsya in the polymer matrix and contacting the other components forming a structure similar to wood.

The experts used retornou and melamineformaldehyde resin, and a mixture of aromatic substances, of which 30% is wood hardwood and softwood. While replacing auxiliary components you can also change the color and other properties of the finished material.

Then made a vacuum drying gave the material to harden at a temperature of 200 degrees Celsius. The resulting material showed resistance to the effects of fire, corrosive acids, and compressed.

3. A group of researchers from the University of Colorado have managed to develop a cheap aerogel. Aerogel is a material with a rigid frame and a large (90%) number of cavities with bubbles of air or other gas. Because of this aerogel is very light, its production takes a few raw materials, but because the particular structure of the frame, the rigidity is enough for you to use aerogel as a building material. In addition, the aerogel has good insulating properties and is permeable to sunlight, but there is the disadvantage that the aerogel matte due to the chaotic internal structure. It is the latter property, and decided to change the team.

The basis of the framework of a new type of aerogel is cellulose. It is very much in the waste of brewing beer wort, which at the moment simply utilized. So to “space material” is possible for mere pennies. Some plants will only be happy if they get rid of the huge amount of waste material. In the process, the wort is a special kind of aerobic bacteria transforms it into nano filaments of cellulose, resulting in a transparent flexible film, and the heat resistance of such material is so high that it is no problem to put some time into the fire. The authors believe that the new material can be used in space missions.

Transparent, lightweight and durable insulation would help, for example, the Martian colonists. You can “collect” sunlight passing through the heat-insulating window and keep heat inside the building, avoiding hypothermia.

4. A large army of fans of NVIDIA for months he prays to the manufacturer to present the new generation of gaming graphics solutions GeForce. As for the new gaming graphics cards, their official announcement will likely take place next week. At least this suggests NVIDIA posted a teaser.

In the video shown you can catch a glimpse of a new graphics card in the updated reference design. In addition, the video contains some hints on what is the name of a new line of graphics accelerators. As a professional solution, new gaming graphics card would probably be built based on the architecture of Turing, the main feature is the use of new independent nuclei RT Cores to support ray tracing technology intended to substantially improve lighting in games. NVIDIA describes itself to support implementation of ray-tracing as the biggest step forward since the announcement of CUDA technology in 2006, so at the presentation about this technology, we will definitely share more. At the same time, many are waiting for the announcement of graphics cards with a confident support games in 4K resolution at 60 fps.

Professional media make assumptions about what the range RTX from NVIDIA will not become a replacement for the GTX, which now produced all game solutions, but rather complement it.

The announcement of the new gaming solutions will be held August 20 in Cologne at the Gamescom gaming exhibition in 2018.
