For commercial use, this is designed for business areas that draw upon customer and parftner engagement—offices, conference rooms, classrooms, showrooms, restaurants, retail shops, bars. Microsoft and Samsung see the device being used in education, financial and professional services, healthcare, hospitality, retail, and manufacturing. Scenarios envisioned include a doctor talking to patients and design teams collaborating. (PhysOrg.com) — Microsoft and Samsung have announced the Microsoft Surface computer, called SUR40, as available for preorder, through the Samsung website, in 23 countries. The unique multi-touch screen is shown in a compact, stylish design as a table top but also can take the form of a vertical wall mount. The product is four inches thin, which makes it easy to use in either type of deployment. On walls, the SU40 can be hung or used any other way in custom enclosures. There are standard legs available for table use or a customer can design and attach their own. The SUR40 release is scheduled for early 2012.Those who attended the CES show his year had the opportunity to see this computing device that is a result of a Microsoft-Samsung collaboration. The first Surface PC was released in 2008. Microsoft promo video One promotional piece describes PixelSense technology as giving LCD panels “the power to see without the use of camera.” Vision-based interaction takes place without cameras; the Individual pixels in the display see what’s touching the screen and that information is immediately processed and interpreted, passing the information on to the application. PixelSense allows a LCD display to recognize fingers, hands, and objects placed on the screen. PixelSense uses 2 million sensors built into the panel.The SUR40 ushers in what Microsoft’s designers envision as a next step in computing, where computer users do not solely depend on desk, chair and conventional PC machine but instead think of work done on “surface computing” which might be a computer screen as table top or computer screen as wall hanging. The SUR40 draw will be for its utility in serving up on its thin display information and ideas. End users are seen as business people and other professionals who need to share information and brainstorm on the fly. The SUR40 can track up to 50 touch points simultaneously. The SUR40 has a 40-inch screen with full high definition 1920×1080 resolution. The device uses an AMD Athlon II X2 Dual-Core Processor 2.9GHz paired with the AMD HD6750M GPU, featuring DirectX 11 support. The key attraction is its use of PixelSense technology, which enables touch recognition. This document is subject to copyright.

DOI: 10.1038/nature24476AbstractAncient DNA studies have established that Neolithic European populations were descended from Anatolian migrants who received a limited amount of admixture from resident hunter-gatherers. Many open questions remain, however, about the spatial and temporal dynamics of population interactions and admixture during the Neolithic period. Here we investigate the population dynamics of Neolithization across Europe using a high-resolution genome-wide ancient DNA dataset with a total of 180 samples, of which 130 are newly reported here, from the Neolithic and Chalcolithic periods of Hungary (6000–2900 BC, n = 100), Germany (5500–3000 BC, n = 42) and Spain (5500–2200 BC, n = 38). We find that genetic diversity was shaped predominantly by local processes, with varied sources and proportions of hunter-gatherer ancestry among the three regions and through time. Admixture between groups with different ancestry profiles was pervasive and resulted in observable population transformation across almost all cultural transitions. Our results shed new light on the ways in which gene flow reshaped European populations throughout the Neolithic period and demonstrate the potential of time-series-based sampling and modelling approaches to elucidate multiple dimensions of historical population interactions.Press release (Phys.org)—A large international team of researchers has found that Neolithic hunter-gatherers living in several parts of Europe interbred with farmers from the Near East. In their paper published in the journal Nature, the team describes comparing DNA from several early groups in Europe and evidence of interbreeding. The researchers found that there was a lot more breeding going on between the two groups than has been thought. They found that as the farmers moved in, interbreeding began almost immediately. It continued for approximately the next several hundred years at all of the sites under study, though the team reports a more rapid pace in Spain and Germany than in Hungary.The researchers note that their findings make sense logically, as well—it would seem far more likely that contact between the two groups would result in interbreeding, rather than one group simply out-reproducing the other to the point that the original group simply disappeared.

Credit: Anett Osztás The Neolithic period, often described as the New Stone Age, was a period of human history from approximately 15,000 BCE to 3,000 BCE. It was a time defined by the development of settlements and the refinement of tools and the arts. Prior research has shown that people living in what is now Germany, Hungary and Spain were mostly hunter-gatherers during the early Neolithic period, but were “replaced” by farmers moving in from the Near East (Anatolia). In this new effort, the researchers suggest that interbreeding between the two groups led to the decline of the hunter-gatherers. The end result is that most modern Europeans are descended from the Near East immigrant farmers, but have remnants of hunter-gatherer DNA.To learn more about the early history of humans in Europe, the researchers obtained and analyzed 180 DNA samples of people from early Hungary, Germany and Spain dating from between 6,000 and 2,200 BCE. They used data from the DNA analysis to create a mathematical model, which was used to build a simulation of population interactions in the areas of study.

For many years scientists have strived to improve on the already impressive attributes of silk—some would like to make it stronger, others to produce silk naturally in different colors, while others yet would like to include features such as antibiotic properties. Such efforts have not always been as fruitful as desired, however; thus, research continues. In this new effort, the researchers sought to change the makeup of silk by causing the silkworm to produce and use unnatural proteins.The researchers sought to induce silkworms to produce an amino acid called 4-azido-L-phenylalanine, which the worms would add to the silk they made. The researchers used tRNA synthetase to get their silk-producing organs to create azidophenylalanine and then to accept it as an added ingredient in silk production. They then used a bacterial screening system to weed out the cells that were not receptive to adding the protein as silk was spun. This was followed by the creation of four altered silkworm strains and adding the genes responsible for causing the creation of azidophenylalanine in only the parts of the worm involved in creating the materials for use in spinning silk—allowing it to make its way to other body parts could have led to undesired side-effects. At this point, the team was ready to test their work by allowing the genetically modified worms to spin some silk. Testing of the silk showed that for two of the strains, more than 6 percent of the natural enzyme had been replaced by azidophenylalanine—proof that their technique had worked. The team then demonstrated that adding a protein such as azidophenylalanine could provide a positive function by conjugating the silk produced by the modified silkworms to fluorescent molecules through the use of click chemistry, which caused the cocoons to glow—one bright red, the other green. Explore further Credit: ACS Silkworms fed carbon nanotubes or graphene produce stronger silk A team of researchers with the RIKEN Center for Life Science Technologies and the National Agriculture and Food Research Organization, both in Japan, has found a way to alter silkworm genes to create silk with useful proteins. In their paper published in ACS Synthetic Biology, the group describes their technique and suggest possible uses for it.

DOI: 10.1021/acssynbio.7b00437AbstractThe genetic code in bacteria and animal cells has been expanded to incorporate novel amino acids into proteins. Recent efforts have enabled genetic code expansion in nematodes, flies, and mice, whereas such engineering is rare with industrially useful animals. In the present study, we engineered the silkworm Bombyx mori to synthesize silk fiber functionalized with azidophenylalanine. For this purpose, we developed a bacterial system to screen for B. mori phenylalanyl-tRNA synthetases with altered amino-acid specificity. We created four transgenic B. mori lines expressing the selected synthetase variants in silk glands, and found that two of them supported the efficient in vivo incorporation of azidophenylalanine into silk fiber. The obtained silk was bio-orthogonally reactive with fluorescent molecules. The results showed that genetic code expansion in an industrial animal can be facilitated by prior bacterial selection, to accelerate the development of silk fiber with novel properties.
