researchers tracked the hitherto oldest Sun-like star in the universe. Thus they not only get a sense of how the sun will look like in four billion years ago, but still solve another mystery in cosmology.
He is like our sun more than any other star. Only in one respect he differs: With an age of 8.2 billion years it is nearly twice as old as our Sun, which was 4.65 billion years ago. The speech is from the distant star HIP 102152, prepared by an international team of astronomers now adopted under the microscope. It is 250 light years from Earth and is in the constellation Capricornus (Capricorn). For their analysis, the researchers used a special spectrograph of the Very Large Telescope (VLT) of the European Southern Observatory, which is on Mount Paranal in the Chilean Atacama Desert.The findings inspire astronomers. Because they can not only see how our sun evolved and will look in four billion years, but also give information about the chemical composition of solar-like stars. “For decades, astronomers have searched for twins of the sun, to better understand our life-giving star,” says Jorge Melendez of the Universidade de São Paulo, Brazil. “Since the discovery of the first twin 1997, only very few more were discovered. Now we have thanks to the VLT spectra of special quality and can examine these twins just to find out whether the sun is somehow special. “Melendez led the research group that their study in the journal” Astrophysical Journal Letters “published.
Fact our Sun is the best-studied star at all. For 400 years, astronomers observe our Sun with scientific instruments. But while they could learn something about its current state, but little about his past or future. Although there are models of stellar evolution, which allow certain conclusions. However, to validate this, astronomers must study more sun-like stars that are located in other stages of development. Melendez and his colleagues took to the star HIP 102152 18 Scorpii and even targeted. 18 Scorpii was known that he is younger than the Sun, while HIP 102152 was considered older.

The brashly colorful and rapidly staged Jump & Run “Rayman Legends” appears – contrary to first Announcements – at the same time for all consoles, but can you wanting only one. Which is, the test shows.
No more Wii U-exclusive, but still awesome: The new Jump & Run and brings fans not only the most beautiful, but also the most fun adventure for years. Even threatening the dismissal of Mario as a genre-King
beginning of the year it was announced that the originally exclusive Wii U title is “Rayman Legends” appear for the Xbox 360 and PS3 and was therefore postponed to August, the shouting was great – and not without reason : Business considers the decision of publisher Ubisoft is understandable due to the wider base console. But that totally brushed on the touch screen of Wii U game pad game concept defines a conversion for systems with conventional joypad solution anything but close.
best on Nintendo hardware
Although the “Rayman Legends” looks resettled in an oblique fantasy dream world at first glance like a traditional platform game, is the inventor Michel Ancel and his French team of developers have come up with so many extra levels and special modes that benefit from the special abilities of the Wii U controller that the original game concept can really enjoy exclusively on the Nintendo hardware.
While the “Rayman” “float over chasms of time”-typical combination of hopping, fist vertebrae and feels pretty much the same as the previous “ Sales: Ubisoft Genre: Jump & Run Price: 50 € Difficulty: beginners and advanced Age: 6 years
Graphics: very good control: very good Sound: very good Game Pass: very good Total: good
But regardless, with or without music, with a touchpad or a joystick, whether with Rayman or one of its oblique comic pals: Because of its wonderful homogeneous combination of brilliant 2D cartoon graphics and 3D elements is “Rayman Legends” a real eye catcher. The virtuoso to the crazy game and level design doyen of Ancel turn it owes the title finally, that he can even catch up with Nintendo’s ingenious “Mario” platform games. Tons of unlockable extras, a knuffiger multiplayer mode and the pleasant open structure that a change between each game and narrative worlds allowed at any time, carry their own difficulties in making “Rayman Legends” the best platformer in years. The only downer: The brilliant musical soundtrack and the rest of the soundscape indeed come pretty impressive from the boxes, but were mixed in stereo, multi-channel sound, there’s no. (_teleschau – The media service)
Rayman Legends tested: According to the version for Wii U, there is a terrific jump and run now for PS3, Xbox 360 and PC. Ubisoft has fortunately there verschlimmbessert nothing but a great game implemented properly for the other platforms.
class=”foto_container_center”> Rayman Legends in review: Outrageous good jump and run. (9) [Source: view picture gallery] At this point a big “Atschibätsch” with out stretched tongue to all the Wii-U owners: Because that was once announced as an exclusive game for the Nintendo console Rayman Legends are is now available for the PS3 – and it’s been great! Who has the previous Rayman Origins gambled that already knows what to expect: Seemingly simple Hüpfspielkost in the style of the classic Super Mario parts. But while the Italian plumber loses its radiance for years, Rayman Legends is a prime example of how modern and traditional elements cleverly intertwined with each other.
In terms of game design, the Gehüpfe provides no significant changes compared to its predecessor: Your sprints from left to right drawn by fantastic 2D worlds, beaten up finely animated monsters and collect all sorts of things. The aim of each level is to get as many Teensies (small, knobby blue animals) to liberate. Does not sound very varied in theory, turns out after a few hours of play as a pure software-gold. Because the developers are constantly coming out with new ideas around the corner once you flee from a giant dragon towards level output, sometimes it dives through a labyrinth of caves, sometimes it sneaks through an enemy base that could easily come from a James Bond movie
No question: If there were at universities the course “How to ingenious level design,” the Rayman-makers would pass him with honors. A very clever idea in this context is Rayman’s friend flying Murfie: The Frog Fly-waste interacts with the press of the environment and nibbles for example holes in the architecture level and makes you so the way. It is not uncommon to perfect timing to:. Especially in the last two of the six story-world professionals will be put to the Hüpfprobe itself
I wanna rock with you
class=”foto_right c8″> Rayman Legends in review: Outrageous good jump and run. (3) [Source: view picture gallery] Each completed game section is in addition to an additional, slightly different invasive variant thus: You must master the level again, have this time only 60 seconds to get to the exit – exciting, but partly also stick hard. But the absolute fun-Pops are the five musical levels! In these areas, mostly quite short runs as background music a famous song whose rhythm dictates when you should jump or hit and run.
More people, more chaos
Folksy natures are expected with the multiplayer options of Rayman Legends have their field day: Up to three gamers can always walk with a gamepad and the game world. However, this is a nice little bonus rather than a real added value – because the screen chaos ensures that some serious points are hardly together to master. But at least the simple football game in which you transgress against a ball like crazy to somehow maneuver these into the opposing goal, is good for a fun party night before the PS3.
Here you can see very well how the new iPad will probably look (Photo: Sonny Dickson).
Friday 30 August 2013
If they could be featured soon? New photos show the back and front bezel of the upcoming iPad 5 and the housing of the new iPad mini.
Sonny Dickson, who has specialized in Fotoleaks of upcoming Apple products, presented by numerous pictures of new iPhone models including photos, allegedly showing the backs and front panels of the new iPad. Environment and resources suggest that the recordings from the same Chinese source.
The edges of the New iPad seem to be less flattened than the current model (Photo: Sonny Dickson).
The backs of the large and the small images on the iPads are actually indistinguishable. Based on comparison with the size of a stand on which the devices are mounted, one can see, however, that aluminum housing belongs to which model.
This confirms previous rumors and leaks, the iPhone 5 which largely takes over the design of the iPad mini. It should be much thinner and lighter than its predecessor. Among other things, this could be possible through a more efficient LED backlighting that allows Apple to incorporate smaller batteries in the devices.
Previous leaks confirmed
The photos of the front panel also show that the frame around the touch panel is significantly narrower than the iPad 4 Also evident on the Sonny Dickson photos of the two separate volume buttons and the holes for stereo speakers, who were already seen on other iPad 5-leaks. To the inner life is so far not much is known, the iPhone 5 will have an improved processor and an 8-megapixel camera.
This should be back sides of the iPad mini 2 (Photo: Sonny Dickson).
The iPad 2 Mini says little from the back because the new device externally hardly likely to differ from the current tablet. Here’s the big question is whether it will have a retina display or not. For a long time it was said that Apple will introduce this year, only an improved device without high-resolution screen, a retina display follow until 2014. But after Google submitted with the super sharp new Nexus 7, there are rumors, Apple pull the retina iPad mini before.
September, when Apple presented the iPhone 5S expected and the iPhone 5C, the new iPad will almost certainly not be of the party. More likely is a separate October or November date.
smolders among consumers has long suspected that manufacturers shorten the life of their devices targeted. However, an evaluation of the Stiftung Warentest shows: This is not the case. Nevertheless, manufacturers have their tricks to boost sales
div equipment manufacturers do not build targeted vulnerabilities in their products, so that they will prematurely broken.. The test results of the Stiftung Warentest from years past provide no evidence for it so far, as the magazine reported “test” on Thursday in its September issue. Nevertheless, the companies expect, how long to hold an electric toothbrush or a vacuum cleaner. In a way, there is therefore a planned wear, report the tester. Frequently the rule: the more expensive the longer lasting
smolders among consumers has long suspected that manufacturers limit the lifetime of their devices intentionally to sell more.. An evaluation of fatigue tests by Stiftung Warentest in the past decade has shown, therefore, that household appliances not frequently go broke sooner than today. Nevertheless, there are noisy “test” tricks that the manufacturers boost their sales. These include high repair costs, permanently installed battery, lack of spare parts, printer, display the empty cartridges falsely or products that can not be repaired.
In their devices, manufacturers are consequently planning at the production stage, how long to keep it. The customer knows about it but nothing. According to Stiftung Warentest are generally cheap cell phones often faster than expensive scrap. For washing machines under 550 euros, battery drills under 50 euros or 80 euros vacuum cleaners under the danger is great that the joy does not last long on the new device. A guara ntee is not however the price. The testers list also costly flops on as an espresso machine for 985 euro or a food processor for 340 euros, which proved to be very robust and less persistent
. Already one presented in the spring on behalf of the Parliamentary Group of the Greens study had shown that the economy an early wear often with schedules already in the design and manufacture of their products. This is also known as “planned obsolescence”.
Were it not for the many ice, the sight would be breathtaking: a ravine at least 750 miles long, up to 800 meters deep and are, ten kilometers wide. No man has ever get to see, millions of years ago they disappeared under the ice. Two miles up the glaciers of Greenland today towers above the canyon. But now scientists have made it visible -. Using radar data collected in numerous flights
As the researchers to Jonathan Bamber of the British University of Bristol in the journal “Science” write the canyon is probably older than the ice surface, the Greenland conceals since about 3.5 million years ago. They have the shape of a meandering riverbed and stretches from the center to the northern tip of the largest island in the world. Its dimensions are impressive: although it is only half as deep as the famous Grand Canyon at its deepest point. But it is at least 300 kilometers longer than the famous gorge to the U.S. state of Arizona.
But the sheer size is not the most important by far. Bamber and his colleagues suggest that the canyon plays an important role in directing the water from the melting process on the surface of the pack ice to the edge of the ice and ultimately into the Arctic Ocean. Before Greenland ice sheet is formed about 3.5 million years ago, a river must have cut the canyon from the rock.
Its function as a water manager, he apparently has not lost – only now he leads the glacial meltwater. This explains, according to the researchers about why there are no lakes in the Greenland ice pack, unlike in the Antarctic. In addition, water plays an important role in the behavior of the ice. It spreads over large areas from below, it can act as a lubricating layer between the bottom of the glacier and the rock, and so accelerate the slipping of ice into the sea.
Greenland is one of the regions most affected by climate change. The sea ice shrinks rapidly, and also the land-based ice is locally strongly decreased. The new data may help to refine models of the movements of the Greenland ice sheet, according to Bamber. However, he does not expect a fundamentally new insights into how climate change is affecting the glaciers in the far north.
expressed a similar David Vaughan of the British Antarctic Survey: The discovery of the giant canyon will probably have “no special influence” on the calculation of Eisflussraten. The canyon lies so deep under the ice that he probably still remain untouched for many decades by the effects of warming.
the canyon was discovered with the help of radar observations. Bamber and his team evaluated from large amounts of data that were collected approximately at the “IceBridge” mission of the U.S. space agency Nasa and researchers in the UK and Germany. In the electromagnetic waves of certain frequencies of the radar can penetrate and bounce off the ice cream from the underlying rock. While they were evaluating all radar data systematically, the scientists discovered the canyon and were able to reconstruct its shape.
The canyon is not the first spectacular discovery under the ice of Greenland. In 2009, researchers had discovered there a “ghost mountains” that resembles the Alps. 2012 was added in a magnificent valley, take one of the scientists that it could speed up the flow of ice into the sea. All this refutes the impression that the landscape of the earth has already been mapped and explored completely, says Bamber. “Our research shows that there is still much to discover.”
the Greenland ice lies a canyon of gigantic proportions. As the researchers reported in Science magazine , it is at least 750 kilometers long and 800 meters deep, significantly longer than the famous Grand Canyon in the southwestern United States.
previously unknown canyon was probably older than the ice surface, the Greenland covering over millions of years. It has the form of a meandering river bed, ranging from the center to the northern tip of the largest island in the world.
The research team, led by Jonathan Bamber of the School of Geographical Sciences at Bristol, England, believed that the canyon plays an important role in the water from the melting process on the surface of the pack ice to the edge of the ice and ultimately into the Arctic to conduct ocean.
tracked by radar
Even before the emergence of the ice surface at least four million years ago, the gorge was a gigantic bed of a river system is an important way for the water outflow from the island. The presence of the canyon loudly declared Science , why is unlike other Arctic regions are no lakes on the Greenland ice pack.
was discovered in the canyon using radar observations. Bamber and his team evaluated from massive amounts of radar data that had been collected over decades by the U.S. space agency Nasa and researchers from the UK and Germany. In certain frequencies, the electromagnetic waves of radar can penetrate the pack ice, and then they bounce off the underlying rock. While they were evaluating all radar data systematically, the scientists discovered the canyon and were able to reconstruct its shape.
The discovery of the canyon belies the suggestion that the landscape of the earth has already been mapped and thoroughly researched, Bamber said. “Our research shows that there is still much to discover.”

After the EU Commission gave the green light to “VDSL Turbo” about a week ago, the Federal Network Agency has made its decision on the use of so-called vectoring on Thursday officially. The new technology allows transfer rates of up to 100 megabits per second of VDSL ports.
Now it is up to all companies willing to invest to take advantage of the opportunities for the development of modern telecommunication networks and to promote the rapid deployment of broadband networks, said Jochen Homann, President of the Federal Network Agency. The Telekom as an operator of the largest German fixed network was prompted to change their model contracts for access to the network for its competitors accordingly.
Since the vectoring technology requires access to the entire harness, is when they are used in street cabinets (CCC), no place for two providers. The industry leader now has to ensure that competitors are able to offer their products to end users in other ways. Under “special conditions” may Telekom but still access to the “last mile” on CCC refuse to allow them or another company may use vectoring there.
a first draft of the vectoring requirements, the Agency had partially adjusted in July in favor of telecom competitors after the network operators and associations VATM Breko took to the barricades. Industry representatives spoke of the “re-monopolization” of the fixed network. In the current setting, the Bonn Authority has improved, among other things, the existence of protection for users in the CCC. (With material from dpa ) / (sybe)
How much has changed in the sun over billions of years? Astronomers have now discovered for the first time a star of our central star resembles like an identical twin, but is much older.
changed how strong the sun over the course of billions of years? Astronomers have discovered a star for the first time, of our central star resembles like an identical twin, but is much older.
A newly discovered twin star of the Sun shows, according to experts on the future development of our solar system. An international team of astronomers has identified the Brazilian line with the Very Large Telescope (VLT) of the European Southern Observatory ESO far the oldest twin of the sun.
The observed at the Paranal Observatory in northern Chile star HIP 102152 was similar to our sun as an identical twin, but emerged with an estimated age of 8.2 billion years, much earlier, shared the Eso on Wednesday.
This enables the observation of a much later stage of the evolution of stars of the type of our sun, which is only 4.6 billion years old. The first realization was found that the lithium content of the star decreases with the increasing age.
lithium, the third element of the periodic table was created during the Big Bang, together with hydrogen and helium. Astronomers are wondering for many years, why some stars seem to have less lithium than others.
star destroy their lithium over time
The new observations of HIP 102152 astronomers of the solution to this puzzle are now one step closer by found a strong correlation between the age of the solar-type stars and their lithium content have.
Our Sun has now only one percent of the lithium content, which was present in the material from which it originated. Recent studies solar twins suggest that young sun-like stars have a much higher lithium content. Researchers, however, were not yet prove a link between age and the lithium content in the layer.
talawanda Monroe, co-author of the paper reporting, summarizes: “We have found that HIP 102152 has a very low lithium content This shows for the first time clearly that older Sun in Gemini. Indeed, a lower lithium content than our sun or younger solar twins. We can now be sure that stars destroy in any way their lithium when they are older, and that the lithium content of the Sun’s normal for her age. “
“For decades, astronomers look after twin stars of the sun, to better understand our own life-giving star,” said the head of the research group, Jorge Melendez of the Universidade de São Paulo.
When the earthly life ends
From the comparison with the Sun, the astronomers could also see that at the 250 light-years distant star HIP 102152 in the constellation of Capricorn Earth-like rocky planets could include.
scientists predict that our sun will shine brighter ten percent already in a billion years from today. That’s enough for the ultimate climate catastrophe. Temperatures will then be on earth mean of 50 degrees Celsius.
latest move in a few billion years the hydrogen reserves the sun is low. Before the end of life but it will swell again huge, first swallow the planet Mercury, then Venus, and finally the earth.
China is on the road to super space nation: The People’s Republic in 2013 for the first time will still end up with an unmanned space shuttle to the moon with a rover and explore the earth’s satellite
China is on the road to super space nation: even first time in 2013, the People’s Republic will end up with an unmanned space shuttle to the moon with a rover and explore the Earth’s satellite. From Johnny Erling
Beijing authorities have started the countdown for the launch of ambitious moon welfare programs in the country. End of the year is to be the first unmanned moon landing by ferry.
you will send out a self-developed, from the ground-controlled lunar rover on three-month test-drive and explore it and let the national flag hoisted on the moon: “We are preparing to launch the launcher with the lander and rover on the moon on board, “stated the State Agency for Science, Technology and Industry for National Defense announced.
As the official news agency Xinhua reported, will start the named after a legendary Chinese moon fairy “Chang’e I” lunar exploration program on satellite space station Xichang in southwest China. With the Chang’e-3 will start the second of three phases in the Chinese lunar journey, stand for the three abbreviations: Rao (the lunar orbit), Luo (land on him) and Hui (return from the Moon)
The first phase of China has launched in 2007 and 2010 with the previous projects Chang’e-1 and Chang’e-2 behind. Both spacecraft orbited over a year, the Earth’s satellite systematically in order to measure him for a complete topographic map of the surface and to select a specific landing site for their lunar module into the so-called Rainbow bays of the moon.
ferry is already in just over three months to land
Now the Chang’e-3 will land there in just four months. “For their transport is improved and proven launch vehicle available,” Xinhua quoted the commander of the trip to the moon program, Ma Xingrui.
For the lunar module itself new technologies have been developed, particularly to ensure a soft landing. But he warned: “The mission is extremely difficult and associated with great risks.”
Chinese media speak of a “milestone” for the ambitious Aufholprogramm the country – more than 45 years after the first manned U.S. moon landing. After a successful landing of Chang’e-3, which remains on the moon, at least two unmanned ferries, Chang’e Chang’e-5-4 and follow to take rock samples and these ferries and then from 2017 to to bring back Earth.
Only after that China’s space could prepare to send to a yet undetermined time after 2020, the first time a Chinese astronaut on the Earth’s satellite.
The decision for the first unmanned moon landing was before the year according to the “People’s Daily” a day after the new leadership in Beijing had set the date for their planned major economic party. In November, the Party Central Committee will meet to decide on China’s new economic reform programs to advance its economic and social development to the symbolic date of 2020.
Prestigious Aerospace and military calculus
Beijing’s goal is by 2020 to make the People’s Republic from developing countries to wealthy great power and turn it into a rich world power in the second stage by 2050. The prestigious space, behind which is also military and economic calculus, based on these policy guidelines.
The expansion into space is based on three pillars: the, launched in 2003, the Shenzhou manned space missions, begun on the construction of a space laboratory Tiangong-from which to 2020, the first own space station will emerge and the Chang’e lunar exploration program.
China remains tight-lipped when it comes to the cost of the giant state project. According to the official business newspaper “Jingji Ribao” provide several hundred thousand people in 110 laboratories and research institutions in the country among active employees of approximately 3,000 companies and businesses.
The real costs are completely transparent. After a few official figures, the manned space flight to date with ten Shenzhou missions supposedly only 39 billion yuan (4.6 billion euros) and the Chang’e 1 and 2 have tasted of the moon exploration program together 2.3 billion yuan. Other details were not disclosed.
Manned Moon mission planned station and moon
for the manned moon trip there, according to the chief scientist of the lunar program, Ouyang Ziyuan, no concrete schedule, announced “Shanghai Daily”. In planning for the trip to the moon program is after a landing of astronauts also planned the construction of a lunar base.
over there built telescope and telecommunications equipment will explore space and Mars for further expeditions in the future of China from the moon scientists.
The immediate goals, however, are down to earth. Chang’e-3 will carry China’s national flag and hoist spectacular on the earth satellite, announced the chief engineer of the lunar program, Ye Peijian, on the outskirts of Beijing at parliamentary sessions last March.
The making of the flag, the researchers would have faced problems because they must withstand the extreme temperature fluctuations to minus 170 degrees in the prolonged night periods.
lunar rover was tested in the Gobi Desert
China’s space scientists go anyway safe: The Chang’e-3 will orbit the moon to its landing over 400,000 kilometers to an altitude of 15 kilometers, to ensure is when and where it lands. To the predetermined place in the bay of the rainbow (sine Iridium) there was four other alternatives.
than five years, in February 2008, the project had been prepared, Wu Weiren, one of the chief engineers and designers said. The approximately 100 kilograms, equipped with solar panels moon vehicle, which was tested in the Gobi desert to be conducted by remote control from Earth.
greatest concern of scientist: China’s lunar rover, which should be at least three months in use, must be zurückdirigiert repeatedly in the protection of the ferry before it gets icy nights. And he must on no account fall into a moon crater or a lunar trench.

Global warming currently seems to take a break; climate change skeptics feel vindicated. , According to U.S. researchers, however, natural temperature fluctuations in the tropical Pacific are responsible. After the cool phase, it will be back hotter world.
The apparent break of global warming can be explained by natural temperature variations in the tropical Pacific, according to a U.S. study. The researchers conclude the climate Yu Kosaka and Shang-Ping Xie at the Scripps Institution of Oceanography, University of California from their simulations. In the British journal “Nature” they make a custom air-computing model that reproduces the observed temperature evolution well.
Despite the rapid increase of greenhouse gases in the atmosphere, global warming seems currently to take a break. For some 15 years, the temperature of the air near the ground has not risen appreciably in the global average. This surprising development has previously seen a climate computer model. Researchers puzzle over the reasons for climate change skeptics feel vindicated.
fluctuations cover climate change
natural fluctuations in the climate system can currently cover climate change, as the authors explain. The current unusually cool surface waters of the eastern equatorial Pacific, thus cooling the atmosphere and thus slows down the global warming. The reason for the cooling of the tropical Pacific is not yet clear, the climate researchers write. However, it is likely that it was a natural fluctuation. If this is so, the global warming by the end of the cool phase of the sea would continue, scientists predict. Similar phases are also possible in the future.

The two experts were fed a climate model with the anomalous surface temperature of the eastern equatorial Pacific. Although this only about eight percent of the earth’s surface, it can affect the air temperature around the world. The oceans hold about 90 percent of the additional heat. And the water temperature in the upper 2000 meters has increased steadily according to data from the U.S. NOAA Ocean Research in the past decades, while the apparent climate change pause.
Hotter summer on northern hemisphere
The modified calculation model now not only reproduce the observed break of global warming, but also regional and seasonal phenomena, the researchers report. So would about the summer in the northern hemisphere still hot, during the months of November to April, a cooling being observed. This also give the model again, albeit less pronounced than in the measured data.
addition, the observed significant slowdown in North West America find also in the modified climate model again as prolonged drought in the southern United States, the team writes. Eurasia for the model calculation, however, does not agree so well with the regional measurements match, which probably lies at an internal climate variability, regardless of the development in the tropics.
internationally little-known Chinese smartphone maker Xiaomi has committed one of the leading managers of Google Android. Hugo Barra, which was responsible for Internet Group for the Android product management, is intended to promote international business in Xiaomi.
class=”bild_links c1″> Hugo Barra Barra confirmed the change on Thursday an entry on Google Plus. He was last seen more often in performances of devices with Android on the stage, he recently unveiled the tablet Nexus 7
Sundar Pichai, who is responsible for Android, Chrome and Google Apps at Google, Barra congratulated for his “next exciting adventure.” “We will miss him but at Google and are thrilled that he remains connected Android.” Most devices of Xiaomi run with the Google system.
smartphone business in China – the world’s largest mobile phone market – is dominated by local vendors. Companies such as ZTE, Huawei and Lenovo are thus one of the world’s leading smartphone vendors and expand internationally. Xiaomi was founded in 2010 and made with cheap high-end devices for attention. (Dpa ) / (anw)

class=”wp_keywordlink”> Samsung will open up with the Galaxy Tab 3 kids in the near future a new target group. The tablet comes in toddler-friendly colors with a rounded stand, reminiscent of baby toys and you might come across in some ten year olds to rejection. At the International Consumer Electronics Fair (IFA) in Berlin will be demonstrated for the first time next week.
Technical basis is the standard Samsung Galaxy Tab Tablet 3 Android and 7-inch screen. Except for a protective Case with Stand Samsung has added software engineering and its usual TouchWiz interface is replaced by a fairer child. Also, educational software and games for children are playing up at the factory.
Google Play to access the children’s tablet on a special app store for children. Presumably can prevent this by default, their offspring may invest larger sums in software there parents. As child protection, there is also a timer: If specified by the parents daily service life, the tablet turns off by itself
The resolution of the screen will be 1024 x 600 pixels. The children also have to make do with a 1.2 GHz dual-core processor and Android 4.1 Jelly Bean. The difference with the current Android 4.3 due to the intermediate grade children surface but should be hardly noticeable.
Samsung’s IFA stand 3 is probably find a place alongside the Galaxy Tab Smart Gear Watch Galaxy and the Galaxy Note phablet third Both Samsung will officially take place on two days before his exhibition opening press conference on 4 September imagine how company representatives have announced. But on the market it comes first in Samsung’s native South Korea, and still this month. A release date or price for other countries is not known.
