3D Printing Can Create Human Tissue To Heal Wounds

3D printers are able to manufacture spare parts for satellites, food and even human organs. Today, the world of fashion began to use 3D printing and designs luxurious rooms also. 3D printing is diversified more. This is explained by the improvement of materials incorporating different metals and materials such as plastic, wood or nylon. Jewelry and accessories 3D printed are already marketed. An Atlanta entrepreneur currently testing a printer that allows you to create unique garments from fabrics polymer material based on carbon.3D printers never cease to amaze us!

After the ability to print food, dentures or even houses, a new stage has been reached, that of bio-printing In other words, the creation of human tissues in 3D. The bio-printing is a matter of well-known research for the scientists and functional technology is already exists with pre-established patterns. The latter is however very demanding and allows no margin of error or modified during printing.

The apparatus used consists of two tanks containing stem cells bathed in culture medium. This method may be about to be replaced by another discovery by laboratories of Carnegie Mellon and Brigham and Women's Hospital in Boston. It is based on the micro -robot capable of assembling different materials, in order to repair human tissues. Researchers led by Savas Tasoglu and Utkan Demirciont developed a hydrogel material a liquid portion and a solid portion similar to contact lenses which are found in living cells.

It is then necessary to control micro- robot remotely using magnetic fields capable of moving between different hydrogels to build cell structures. It is very difficult to realize that human tissue is composed of many types of cells operation. Scientists have still managed to catalog several materials they need to print in 3D to develop these structures such as copper rods, polystyrene beads, silicon chips and the famous hydrogels. The whole is dipped in a liquid to maintain the cells to be alive.

This approach is more accurate than the old method used previously when it comes to print components. It also makes it possible combining flexible and rigid materials together, all at a scale of the order of tens of microns of size, which is adjustable by the micro- robot. Metin Sitti, the professor of Mechanical engineering head of the Laboratory Nanrobitcs Carnegie Mellon told that their work will revolutionize the precision assembly of blocks of complex and heterogeneous tissues in three dimensions and facilitate the understanding of tissue engineering systems.

The encoding method and manipulation developed here may find wide applications in areas such as diagnostics, regenerative medicine, engineering micro physiological systems, pharmaceutical and biological research, and manufacture microscopic according to Utkan Demirci.

 The micro- robot can analyze cells, manipulate eliminate targets or change direction on a scale that we could not reach before and it can be regarded as a microscopic clamp capable of gripping and moving individual cells or groups in a 3D environment.

Microsoft Announces DirectX 12 On March 20

The Game Developers Conference to be host the late giant, which must unveil the new version of the API dedicated to the video game. The Windows - maker Microsoft has announced a new version of its graphics platform DirectX - DirectX 12 In a blog entry on the developer side of the Microsoft Developer Network, this is the company’s first published preliminary info. Microsoft will announce on March 20 the new version of DirectX API dedicated to video game developed over the years by the giant.

He unveiled at the Game Developers Conference (GDC) in San Francisco, during a session on the future of DirectX. According Polygon, eight workshops dedicated to Microsoft DirectX 11, but prepare the future. The giant did not hide it also, which gave appointment on the date specified by the newspaper on MSDN. Microsoft made a trailer focused on machine performance, and their exploitation by video games. Several presentations sessions of GDC are however state the future of graphics, Direct3D, etc.

Each time, they promise the developers for a unprecedented level of control equipment and increased to a broad hardware ecosystem performance. In short, if you are sure that the new version of the API will be presented on March 20 - and that's a good thing, the previous major version for Windows from before 2009 - there are quite a few details the direction taken by Microsoft.

Microsoft announces new graphics platform DirectX 12.

Opera 20 With Better Speed Dial Operation

Opera Software has released new version Opera 20 of their browser, which relies on Google's Chromium engine for some time. Above all, there are improvements in the speed dial operation and drag-and- drop capability also has been enhanced. With Opera 20, the Norwegian browser receives once again features the owners of Presto - execution have long been accustomed to.

Since Opera is changed months ago on Google's Chromium engine, the manufacturer is busy trying to integrate the functions of Opera 12.x in the new product. Many features are still missing the with the Chromium version that users of the Presto version have long been known. The latest version brings new features, especially around the speed-dial operation and bookmark management.

The speed dial settings have been updated and the user can change the size of the speed dial icons in the Chromium version. This setting is especially useful for users who have a lot of speed-dial entries and this can reduce accordingly in order to have in view as far as possible all. Speed Dial entries can be moved by drag -and-drop with the mouse in the bookmark bar.

Conversely, it is now possible to conveniently store this as the new speed dial entry that an open web page with the mouse. Was also expanded the Opera menu in order to access frequently used functions directly above it can. On Mac systems, a confirmation dialog can be activated when the browser using keyboard shortcuts Command -Q quits. This is to prevent that the browser is accidentally terminated. In addition browser -Themes load faster and bugs have been fixed.

Opera 20 is available free for Windows and Mac OS X and available for download. The Linux version of Opera does not exist with Chromium engine. In recent years, there have been too few new features.

Since then, Opera Software has changed to the Chromium engine that finds no more development on the browser instead of Presto engine.

Microsoft Plans Language Assistant Cortana For Windows Phone!

Microsoft wants Windows Phone 8.1 to install a language assistant who carries the name Cortana in it. It is said that it is similar to Siri on iPhones and Google Now on Android Smartphones. With the update to Windows Phone 8.1 Smartphones get with Microsoft's mobile operating system a language assistant that is designed to provide the functions of Siri and Google Now, The Verge has learned from people who are familiar with Microsoft's plans.

The designation is based on the computer game series Halo, in which there is the AI Cortana character. On Windows Phone Cortana is only an animated icon and not a female character as in the Halo games. The approach of Cortana is a similar virtual personality as with Apple's Siri. Moreover Cortana collects data from Bing, Foursquare and other services in order to offer comparable performance to Google Now.

The user will thus find all relevant information in Cortana to simplify his use of Smartphones. A sub- function of Cortana is called notebook and is used to control the data flow with matching privacy settings. The user should therefore be set in the notebook, which data sources may use Cortana. So Cortana can on location information, personal data, reminders and contact access. In addition, the function can monitor the user behavior and show based on that information or make suggestions.

Depending on the chosen notebook settings to the Windows Phone Assistant noted the information in question. The user should edit later stored within the notebook information or delete, so that a privacy setting in the base can be changed at any time later. Moreover Cortana can be used to remove the user tasks. For example, if a message comes is asking in for a meeting at 19:00 clock, offers the wizard to create a matching calendar entry.

In addition, a Do Not Disturb mode is scheduled to appear in the notifications. The user may specify a specific user group, which is not affected by the Do Not Disturb mode. News of these individuals appointment would then continue to appear. It is expected that a first preliminary version of the update version will be come to the market only at the beginning of April 2014 is shown at Microsoft's Build conference. When Smartphone owners will get the update is still not known.
