Blackberry hesitate to give continuity to your messaging system ... - TeleCinco.es

BlackBerry company is considering rescinding its messaging service into a separate unit, as has collected the newspaper The Wall Street Journal, citing people familiar with the matter. The subsidiary would be called BBM, the newspaper said.

The firm has been moving BBM team executives and working on other offerings beyond messaging, including some tools already available for BlackBerry users , such as video call, said the newspaper. The company is also considering that BBM is available for computers , indicating the newspaper, citing a person familiar with the matter.

A spokeswoman for BlackBerry said the company can not comment on rumors or speculation . The company said earlier this month it was evaluating options that could include an outright sale. BlackBerry shares fell nearly 2 percent to $ 10.72 Canadian (7.63 euros) on the Toronto Stock Exchange.

Android beats consoles - The País.com (Spain)

Google has surpassed consoles as gaming option. Apple, with its iPhone, iPad and iPod Touch, for more than 18 months to beat Sony and Nintendo. Android is now the second platform digital download revenue in the category of electronic entertainment, ahead of the two Japanese giants.

The joint report by consultancy IDC and specializes in data applications App Annie sheds as that Android users would rather spend money on games rather than applications. Most of the Android gaming revenues come precisely from Asia, especially Japan and South Korea.

is no coincidence that FIFA 14 will be available in phones and tablets. Electronic Arts has taken this a priori risky decision based on his play star quite logical. The two games with higher incomes are theoretically free but pay for supplements, upgrades or extras, Candy Crush Saga and Puzzle & Dragons. In any case, the player of these pastimes are far removed from the usual profile console enthusiast.

Nintendo 3DS dir=”ltr”>

Animal Crossing: New Leaf , Luigi’s Mansion , Donkey Kong Country , New Super Mario Bros 2 and Tomodachi Collection . All of them are unique to Nintendo.

In any case, the apparatus park to play with much different from one platform to another. The study estimated that there are 1,250 of Android phones and 180 million tablets, compared to 200 million park handheld.

Among the keys to this advancement is the ease of payment through Google Play, the showcase of Android, such as expanding to 130 countries in 2011 reached only 30, and that the creation of an area dedicated to games within the overall.

Nintendo, master of laptops from creating Gameboy in the early 90s, wants to regain the throne. His latest venture, Nintendo 2DS unexpected is a dual-screen console but features hinges that were used to close in on itself. One way to save in the construction of the apparatus. The same applies to three-dimensional vision without glasses, eliminating the alleged revolutionary technology to return to the usual two-dimensional single year and a half after premiere. This low cost model will arrive on October 12 for 130 euros.

Sony, which sells two models to carry console, PSP and PS Vita. It also tries to stand up to the mobile phenomenon. The first is focused at children with a price of 100 euros. The second has just suffered a cut in the price of 50 euros. It is on 199 and includes titles. Still does not seem to give reason to carry an additional device in addition to the mobile or tablet.

pains to make us believe that the three dimensions needed to have a more immersive experience. Nintendo 3DS removed two years ago. Last summer renewed this model with a larger screen. Now 2DS surprises with a flat console with dual screen and which dispenses three-dimensional vision.

price, announced in the U.S. for $ 130, wants to very low barrier to entry. Compatibility with Nintendo DS games make it a cheap option to spice previous purchases and use the current catalog with Mario Kart 7, Luigi’s Mansion and Animal Crossing as bait.

Surprisingly

dispensing with the hinge. The console is flat, not closed. A nod to the origins of the laptops, when they brought out the legendary GameBoy, colorless and flat design.

The new laptop will be released on October 12, will include the touch pointer to the bottom screen, internet via wifi and memory card four gigs.

Steve Wozniak Apple wants a mobile than iPhone - Geekets

In a recent interview, Steve Wozniak just said that Apple should be working on a new smartphone that is not another iPhone and can trade in emerging markets to make Apple cover other sectors and can reach more users.Steve Wozniak declared in an interview that he would like Apple set new goals and begin to use neglected markets on the other hand, in order to compete effectively . A Apple smartphone that was not an iPhone could be an interesting measure and cost much less than the iPhone 5C .

Steve Wozniak has always had an interest in everything related to the world of Apple and the technological world , and that is why his words always seem carry much weight, especially with geeks, analysts and computer gurus.

Apple should lose the fear to evolve or change, seek alternatives and exploit new markets (perhaps emerging markets), to open up new possibilities.

To see the video of Steve Wozniak talking about an Apple smartphone was the iPhone , follow this link to lormik, my personal blog is where I have written a full analysis of the news.

Hugo Barra will be the new director of business development ... - MuyComputerPRO

Reuters have revealed what the position of Hugo Barra at the Chinese company Xiaomi . The executive will Google Android to lead the emerging global expansion China in October, holding the position of director of international business development.

Xiaomi founder himself, Lei Jun, said on Weibo (Chinese service similar to Twitter) the new position he would play bar in your company. A company and entrepreneur who blindly follow the Chinese tradition of “copy”, their products claim to be Chinese replicas Apple (but much cheaper) and the image of Jun also reminds the style informal Steve Jobs: black shirts, jeans and sneakers.

Along with their Chinese counterparts, Huawei and ZTE, Xiaomi aggressively has taken market share in that country by combining low prices and quality components, pressure margins and fee market of Apple and Samsung.

Xiaomi latest smartphone, Hongmi, sells for $ 130, much less than the $ 770 the iPhone 5 or the 470 the latest model of Samsung, the market leader in the country Asia, at least for now.

A solar eclipse on Mars - The Mundo.es

scanning probe NASA, Curiosity, has captured images of a solar eclipse from Mars at the time when most of the planet’s two moons, Phobos, orbiting standing between the red planet and the Sun . The images captured by the U.S. space agency are the clearest ever achieved such a phenomenon from Mars.

During the time the eclipse lasted just over three seconds, Phobos has failed to cover the extent of the sun but has been a ring of light that gives this type of annular eclipse, according to NASA, which has turned the spectacular picture on your Astronomy Picture of the Day

“The phenomenon has happened around noon at the place which was the Curiosity, lending the satellite was at its closest point to the probe and looks bigger than usual”, as explained by the researcher University of Texas A & M, Mark Lemmon, who has detailed that this is “the closest thing to a total eclipse can be seen from the planet.”

Moreover, the eclipse, which took place on August 17, surprised observers by passing several miles closer to the center of the sun so astronomers had predicted, so as Lemmon, “learned something” .

A team of scientists from the Institute of Molecular Biotechnology Vienna has just presented to the world the ultimate tool to study the human mind: minibrains grown in a petri dish. The technique presented in Nature, was to create a culture of stem cells able to develop a structure of three or four millimeters in which cells become specialized and similarly to grow as they would in the brain of an embryo a few weeks.

Scientists hope that the model will help explore mental illness such as schizophrenia or autism or to study the development of new drugs without using animal models. Suffice to observe the reactions in these new fabrics and bring them to various tests.

To demonstrate the utility of their model, the Viennese researchers have collaborated with a team from the University of Edinburgh which helped them develop a minicerebro with features of microcephaly, a condition in which the brain grows much less than normal causes permanent disability.

Until now, scientists have recreated in the laboratory models of organs such as the eyes, liver or pituitary gland, but minibrains creating a step further. The model presents distinct areas resembling adult brain regions such as the cortex or hippocampus. The aim of the team is now generating large models and study new diseases.

The girl appeases warming - The País.com (Spain)

Although so far XXI century there have been several years of record highs and that in regions of the world, especially at high latitudes, the observed warming is tenacious, what had been an upward trend of annual average temperatures of the Earth’s surface has stagnated in the past 15 years. Scientists look for an explanation of why global warming seems to have been put on hold, at maximum levels, bearing in mind that the concentration of greenhouse gases in the atmosphere has not only increased inexorably in that period seems to break climate. The stagnation in escalating temperatures due to cooling of the tropical Pacific waters associated with cyclical oceanic phenomenon El Niño / La Niña, explains now some scientists in the U.S.. They claim that when the ocean hot again will resume rising global average temperatures had been so marked that in the last decades of the twentieth century.

“Our results demonstrate that the current interval [in the escalation of the temperature] is part of natural climate variability, specifically associated with La Niña cooling rate of a decade,” writes Yu Kosaka and Shang-Ping Xie ( Scripps Institution of Oceanography, USA) in the journal Nature . “While there may be intervals in the future, the trend of decades of warming is likely to continue with increasing greenhouse gases”, added.

carbon dioxide concentration in the atmosphere has already exceeded 400 parts per million in some observatories measures, compared with 280 ppm before the industrial revolution. This increase in greenhouse gases should be reflected in a parallel increase in warming as basic physics of climate. However, in recent years the average temperature curve in the land surface, rising sharply from the seventies until nearly the end of the last century, it has become an almost flat line. Not that they have lowered the thermometer through the planet, is that it has stopped rising at the rate above. According to climate simulations, it should have been an increase of 0.25 degrees Celsius over the past 10 years, however, were only 0.06 degrees, recently explained the German meteorologist at the University of Hamburg Hans von Storch in an interview in Spiegel .

“There are two possible explanations, and neither is very nice for us [climate scientists],” said the German expert. The first possibility is that global warming is producing less than expected because of greenhouse gases, especially CO ₂ , have less effect than was presumed. “This does not mean that no enhanced greenhouse effect from human activity, but that their influence on climate is not as big as we thought,” explained von Storch. “The other possibility is that, in our simulations, we have overestimated the climate fluctuations due to natural causes,” he added, warning that the scientific problem would be serious if the current is prolonged much more stable temperatures. It is in this second option will fit the work of scientists from Scripps.

Yu Kosaka and Shang-Ping Xie recall that several explanations have been proposed, as the cooling effect of aerosols in the upper atmosphere or the solar minimum phase by 2009. But his response is associated with reciprocating cyclic heating / cooling of the tropical Pacific, which was also on the minds of many as a good candidate to explain the current warming hiatus. They describe in Nature the development of a climate model that fits well in the oceanic oscillation effect of El Niño / La Niña, whose effect is known historically by extreme rainfall and droughts caused cyclically, especially, but not only South America. Its methodology, they say, allows multi quantify the influence of these variations and results obtained with the model correctly reproduces the stagnation (hiatus, they say) in average global temperature curve recorded at the beginning of the century, namely that “reconciles climate simulations with observations ”.

The ocean is full of microscopic algae take carbon dioxide from the atmosphere to grow, and when the amount of CO2 available low, seek alternative fuel supplementary for photosynthesis, such as baking present in the water, with the added cost for energy and nutrients. When increasing the amount of carbon dioxide, stop using the resource, and that is reflected in the tiny shells that some do and microscopic algae that accumulate on the seabed. Two researchers from the University of Oviedo have used these shells now as a record of atmospheric CO2 concentrations in the past to measure the chemical changes that occur in the shells of algae when they need extra fuel, as bicarbonate. Have been traced to the last 60 million years and have found that these algae began to rely heavily on these carbon sources added relatively recently, seven to five million years.

The back of the new Nexus 7. Palou

NACHO PALOU

From today is available in Google Play and electronics superstores tablet new generation of Google Nexus 7 .

With a seven-inch screen, the currently available only in version with Wi-Fi and storage capacities of 16 and 32 GB . Prices are from 229 and 269 euros, respectively. Currently there are no expected arrival date model with mobile access to the Internet but the connection will support LTE / 4G.

Certainly while Google has dropped the price of the phone Mobile Nexus 4 to $ 199 the model with 8GB of memory and $ 249 with 16 GB model. The Nexus 4 has always been one of the more interesting Android phones and at this price it is even more, even near the end of its commercial life.

class=”ladillo”>

Returning to the tablet

star of the day, the Nexus 7 2013 comes with significant improvements over its predecessor . It is lighter and thinner, to resort to a more compact battery and with some smaller capacity. It also dispenses with much of the rubber back.

However, the Nexus 7 is proving very comfortable in the hand (for its size and light weight, 290 grams), while autonomy is not impaired thank new processors and software power management that incorporates Android version 4.3 installed on the tablet, making the role between 9 and 10 hours of battery life playing video and Internet browsing.

Optionally the Nexus 7 can be charged wirelessly, without the need for wired using induction charging base which is optional.

class=”ladillo”>

is Full HD screen with a resolution of 1920 x 1200 pixels with excellent sharpness . This screen resolution allows playback of high definition video in 1080, although an initial impression with playing YouTube videos with this resolution seemed to choke a little.

I’d say the graphics processor to the resolution of the Nexus 7 comes a little big, but probably this is one of those areas where you have to compromise to maintain a selling price more than tempting. The relationship between price and performance is definitely the main feature of this tablet.

However with the operating system and some more or less demanding game I’ve had occasion to try onscreen movements were absolutely fluids . Incidentally, Google also launches Google Play Games to facilitate access to Android games.

One advantage of the sharpness so big it has screen Nexus 7 is that it is convenient read text , even of small siz e. This makes the Google tablet even more versatile as well as tablet can be used as electronic book reader. Through Kindle for Android you can access the complete catalog of eBooks from Amazon, for example.

Premieres class=”ladillo”>

Another novelty of this model from the tablet Nexus 7 2012 is incorporating a 5-megapixel rear camera , which is in addition to the 1.2-megapixel front. Do not expect much from the camera when I made a test shot, but I would say that the result has been quite reasonable if there is enough light.

One small drawback that I appreciated for as long as I can ‘tinker ‘with the Nexus 7 is that horizontal side edges are too thin , leaving little room to accommodate your thumbs. While this remains very content the size of the Nexus 7 (measures only 11.4 x 20 cm) sometimes inadvertently pressing means any part of the screen. It is desirable that the system was able to distinguish when the screen is being pressed voluntarily and when it is an accidental touch when holding the tablet as the iPad does.

class=”ladillo”>

probably find the Nexus 7 does not rival among other tablets with Android operating system. It’s hard to find something like that price. The Kindle Fire HD would be the closest, but it is much less versatile device to be highly targeted to Amazon content consumption.

Samsung has equivalent alternatives, but the closest model for performance, the Samsung Galaxy Note 8 is significantly more expensive and has a lower resolution screen.

offer remains to be seen what the almost confirmed LG tablet with 8.3-inch screen, although input and will be larger than this Nexus 7.

Perhaps by now the Nexus 7 is going to find much of the competition in Android phones lately are quite comfortable with screen sizes of around 5 inches, which increasingly difficult to justify having two similar devices display just two inches apart.

Fair and balanced class=”ladillo”>

powerlessness try more carefully, the Nexus 7 tablet makes a good impression in his hand. Specifications are reasonably good although somewhat discreet at this time of year and its aesthetics and quality are acceptable. The screen is really where this Nexus 7 highlights, and the price and downplays any flaws while magnifying their strengths.

A group in favor of the Syrian regime leaves the web service's' New ... - The Mundo.es

For the second time in two weeks, the website of the ‘New York Times’ Tuesday stopped working normally. But unlike the August 14, the problem is not the result of an internal error but an attack led by the Syrian Electronic Army : a group of computer close to the regime which has shot down in the last months the pages of various media.

The attack was confirmed Tuesday by U.S. newspaper spokeswoman, Eileen Murphy, who explained in several forums that the problem was “the result of an external attack.” But Murphy did not say whether the group was responsible Syrian issue nor when it would be possible to access the web normally.

Yes

admitted in an internal message to the executive Marc Frons, who asked his employees to stop “emailing sensitive” and revealed that they had been attacked “by the Syrian Electronic Army or someone who makes every effort to like them “.

Experts have confirmed that the attack is reflected in the Domain Name System (DNS its acronym in English): a type of phone that directs computers to the Internet pages. At modify the DNS of ‘New York Times’ , the Syrian group may redirect your readers to any web page and give the impression that their servers have been attacked.

type the address of the ‘New York Times’ in the browser, some readers are directed against his will to the pages of companies based in Russia or Syria. These include a website with the logo of the group responsible for the attack, whose leaders are in favor of the regime of Bashar Assad.

As reported by Mashable, the group agreed to the page of the ‘New York Times’ after gaining control of the company Melbourne IT, which also have their domains registered companies like Twitter, AOL, Yahoo, Google or Microsoft. “Who gets access who registers a domain you can redirect web traffic and email Internet to reach these pages to any other server,” said HD Moore Tuesday, expert security firm Rapid7.

Syrian group also said on Tuesday that it had taken control of the domain of Twitter. But for now this point has hardly affected the social network service. The company has said that the problem is fixed and has admitted that for a few minutes hanging images users have stopped working.

Syrian Electronic Army operates at least since the spring of 2011 and is run by the Damascus regime but the Syrian president has recognized his achievements at least once.

According to some sources, the domain of the Syrian group recorded it in May 2011 Syrian Computer Society: official institution presided Asad just before coming to power. But no one dares to say that their members receive a salary from the regime or are directed by its security forces.

Those who have studied their actions are portrayed as a group of civilians who leave comments Asad for Facebook or YouTube forums. But their ranks are computer capable of breaching computer security as relevant media such as Reuters, NPR, Financial Times and the BBC.

Its most striking blow what occurred in April this year when they agreed to the Twitter profile U.S. agency AP and wrote that Barack Obama was wounded after two explosions in the White House. Some phrases that triggered the instant collapse of the Exchange until the denial occurred AP.

The telescope 'Kepler' can no longer search for planets like Earth ... - The Mundo.es

‘planet hunter’ can no longer continue to seek Earth-like worlds. NASA has reported that definitely stops attempts to solve the faults in the space telescope ‘Kepler’, and that, therefore, it is impossible to continue its mission to search for evidence of the existence of Earth-like planets outside our Solar System.

“After months of analysis and testing, the Kepler space telescope team ends its attempts to restore the full functioning of the device, and is now considering what possible investigations can be carried out in its present condition,” reported U.S. space agency.

In May, NASA reported the detection of a “glitch” in the steering system of the device, which had lost control of two of its four rotors, used to stabilize the telescope and adjust the direction of their lenses. The probe orbits the Sun at 64,000 million kilometers from Earth.

technicians efforts “have failed” , the space agency said, recalling that three rotors need to carry out the research work of “exoplanets” (planets outside the solar system).

‘extraordinary discoveries’

“‘Kepler’ has made extraordinary discoveries to find exoplanets, including several super-Earths in the habitable zone. Upon learning that Kepler has successfully collected information from its primary mission, I am confident that more exciting discoveries are on the horizon” said John Grunsfeld, deputy director of NASA’s Science Mission in a press release.

On August 8, the engineers returned to test the operation of the telescope and determined that the rotor is damaged , so it is impossible to “get back to where photometric accuracy that guarantees high precision. “

therefore returned it Safe Mode Controlled Propulsion, which is “safe” but they can not handle their lenses from the operations center.

‘Kepler’, which monitors more than 150,000 stars in search of planets or planet candidates, has been a most successful recent missions of NASA. The data collected by Kepler have confirmed 135 exoplanets and about 3,500 candidates to be .

was released in 2009 in search of evidence of the existence of Earth-like planets or where conditions are middle temperature where liquid water could exist.

With a budget of $ 600 million, was expected to conclude its mission in late 2012, but was was extended for two years until September 30, 2016.

Identified 20 genetic causes of common cancers - The País.com (Spain)

All cancers are caused by somatic mutations: genetic alterations usually not inherited, but have occurred in individual cells throughout life. A crucial issue is to understand what causes these mutations, and international scientific consortium gives today a big step to identify 20 mutational signatures different in human cancers. Each represents a type of mechanism responsible for generating genetic alterations and knowledge “reveals the diversity of mutational processes underlying the development of cancer”, according to scientists, and has implications for the prevention and treatment of this health scourge.

Some of these

signatures , or mutational processes, are present in many cancers, and others are specific to a class or other tumor. Furthermore, some of these mechanisms of genetic alteration are due to age, other systems defects in genome maintenance and repair, and other environmental mutagens as a snuff (in the lung) or ultraviolet light (in cancer skin). The data also revealed in many cancers small regions of DNA that hypermutation suffer a much higher degree of disturbance to the rest of the genome.

Some mutational processes are shared by many tumors

The consortium involves researchers from 14 countries and was coordinated by Michael Stratton and his colleagues at the Sanger Institute in Hinxton, UK. The Spanish contribution is led by Elias Campo, Hospital Clínic-IDIBAPS and University of Barcelona, ??and Carlos Lopez-Otin, Institute of Oncology, University of Oviedo. This is a comprehensive work that scientists have analyzed the genome of 7,042 tumors of all types, which together contain no less than 5 million mutations.

Total . The Spanish Society of Medical Oncology (SEOM) indicates that each year nearly 200,000 diagnosed cancers in Spain (specifically, their estimates are 196 902 cases), and collected just over 100,000 deaths (104 156). The figures do not include nonmelanoma skin.

Colorectal . is the most frequent: 28,551 per year, with a mortality of about half.

Prostate . is the second in incidence: 25,231 cases a year, with 6,000 deaths annually.

Lung . It affects about 23,000 people a year, most (approximately 85% of total), men.

Mama . 22,000 are diagnosed annually, and die of it about 6,000 people.

Bladder . is, in absolute terms, the fifth in incidence: 13,008 cases per year, with a mortality of 4,820 people a year.

By gender . Of the total, 60% occur in men and 40% in women, although the difference between the sexes is reduced gradually each year.

With those numbers, it is truly remarkable that they have been able to reduce the mechanisms responsible for only those 20 mutational signatures different. In fact, some types of cancer have only two signatures, which implies that there are only two mutational mechanisms involved in their genesis. Other more complex tumors come to display up to six firms. In total, scientists have examined the 30 most common cancers.

A good example of how the work is distributed between the consortium is the Spanish contribution, which has focused on a hundred genomes of a particular type of cancer, chronic lymphocytic leukemia. The results showed that the tumor of blood cells is generated by two basic processes, one due to aging and other deficiencies in DNA repair mechanisms. As damage to the genetic material are constant throughout life, our survival actually depends on the continuous action of these processes of repair and genome maintenance, when they fail, spontaneous mutations accumulate with fatal results.

“Without the international collaboration of all working groups involved in the project,” says Lopez-Otin, “would have been impossible to obtain these important results.” Field added: “This is one of the first examples of the new vision that can deliver the massive sequencing genomes and coordinated through the International Consortium Cancer Genome”. In these times of budgetary stinginess, it is fair to add that the Spanish part of the project has been funded by the Ministry of Economy.

One of the most peculiar phenomena which revealed international work are small areas of the genome that suffer some abnormally high mutation rates (hypermutation). Scientists have dubbed the kataegis , for the Greek word for storm. It is not that chromosomes break or shuffle: mutations that occur there are so punctual (letter changes of DNA by another) as those occurring in the rest of the genome, only occur at a rate stormy : to many thousands of mutations in a small space.

Although kataegis , or storms mutations themselves do not consist in chromosomal breaks, it does often occur in the vicinity of one of them. Specific areas where they occur-both as chromosomal rearrangement mutations storm-are quite reproducible in each type of cancer, but vary between types. The kataegis are common in breast cancer (which in fact were discovered), pancreas, lung, liver, medulloblastoma, lymphoma and B cell acute lymphoblastic leukemia.

A class=”texto_grande”>

phenomenon storms vaguely similar to mutation occurs during the normal maturation of the lymphocytes, the white blood cells which produce antibodies and other specialized proteins in the body recognize foreign agents. Since these pathogens are potentially infinite, the antibody genes using a variety of mechanisms to generate a range specificities indefinite equally and hypermutation-controlled and restricted to certain very specific areas of the gene, is one of its main resources. Indeed, kataegis in lymphocytes cancers such as lymphomas, tend to occur in the immunoglobulin gene, the components of the antibodies. In other cancers not, however.

“is more likely to be discovered mutational signatures” Stratton and colleagues recognize in the main article on the subject in Nature , “with a precise definition of their characteristics, as the number cancers sequenced genomes increases and refining analytical methods go “. Scientists claim to have found all of the processes responsible for cancer mutations, although they believe they have most of them.

The genetic signature of cancer - Reuters

stride to understand cancer and move into prevention . This time experts from around the world involved in searching the genome cancer analyzed the mutational signatures, mutation processes in the DNA of cells (which are always at the origin of cancer) and follow a fixed pattern. They have found that 20 patterns explain most of the mutations found in the 30 most common cancers. Some of these are very common patterns are repeated in most tumors but are cancers such as leukemia and lymph nodes, which have unique patterns.

The study on cancer signatures published mutational today in the journal Nature and was performed by an endless list of researchers included in the International Consortium Cancer Genome (ICGC), one of the most ambitious international projects for the understanding of cancer. This is the first comprehensive compendium of these mutational processes that generate tumors.

They analyzed almost f ive million mutations from 7,042 cancer samples. The number is important, because the results are much safer. They found more than twenty different patterns, these mutational signatures. Mutational signature is a genetic alteration mechanism which always occurs in the same way. For example, an error might be: if the cell DNA is disrupted the letter A and the letter T in front of him, that A is changed to a C. And there begins to create a tumor.

This important finding is the result of international collaboration research teams from 14 countries, including Spain, and was coordinated by Dr. Michael Stratton of Sanger Institute ( Cambridge, United Kingdom). Spain is responsible leukemia genome and its contribution to this study has been the identification of two fundamental mechanisms that cause mutations in chronic lymphocytic leukemia. The scientists who run it, Dr. Elias Campo, the Hospital Clinic-IDIBAPS and UB, and Carlos Lopez-Otin, the University Institute of Oncolog y, University of Oviedo, have discovered a mutational signature linked to age and another, the own DNA repair system. “The error occurs just when introduces an enzyme to repair damage to the DNA of the cell, the organism does something continuously. But one of every so often, the system makes a mistake and does not perform well this repair. And always wrong with the same pattern, “said Dr. Elias Campo. And then the change starts and cancer.

In this case and in many other mutational signatures described in this investigation, which causes the mutation, and thus cancer is not a external action, a cause exogenous. But endogenously. Thus appears a kind of inevitability in a significant percentage of tumors. “The genomic damage by exogenous agents often arise, such as snuff or ultraviolet light, and are therefore perhaps avoidable genomic damage or at least minimizable” Spanish scientists argue. “But also arise from endogenous changes arising, f or example, of the imperfection of the biological mechanisms of replication or DNA repair. Such imperfections have allowed biological evolution, but also we have focused on developing processes such as cancer.” And that is the case of at least one of the mutational signatures chronic lymphocytic leukemia: no agent that generates outside, not a familial defect. Only malfunction of DNA repair system.

The ICGC want to launch in a few months PanCancer Genome, a new project to compare the genomes of different cancers and define common genomic alterations the specific. “A challenge to manage and understand the vast genomic information being generated,” says Dr. Field.

United States vetoes on Samsung products by the will of ... - MuyComputerPRO

advantage for Apple in the United States on Samsung. Apparently the Cupertino company has managed to block several Korean products on U.S. soil in the mobile sector. Such decision has been the result of a lawsuit filed two years ago in 2011. While the decision may be appealed, the justice has already acted vetoing products like Galaxy S 4G and Galaxy Tab tablet. Fortunately for Samsung , four products have been saved from the prohibition for enforcing the rules on intellectual property.

Specifically

are infringed two patents by the Asian company, one related to technology touchscreen and double tap the user has to make to increase or decrease the zoom and the other related to the connection of terminals with headphones.

All I can do Samsung is trying to prove that the technology used is not copied to the Apple . In addition, the company will ask the president of the United States, Barack Obama , which reversed the decision because it has 60 days to make the veto. For its part, the South Korean government believes the court decision as an act of protectionism.

Samsung will appeal the decision of the United States to ban ... - 20minutos.es

class=”text”> Samsung Galaxy.

South Korean giant Samsung Electronics announced Saturday that he will appeal the ruling of the International Trade Commission (ITC, in English) U.S. to ban the import of several of their products violate Apple patents U.S..

“We will take all necessary measures, including legal action , so that our requests are reflected in the ruling,” he explained in a statement Samsung, world’s largest maker of smartphones “.

On Friday, the ITC found that Samsung infringed on Apple’s U.S. patent on scrolling mechanisms and headphone input systems, which agreed to ban products that violate the license, such as smartphone Galaxy S 4G , the tablet Galaxy Tab and devices 2010 and 2011.

However, the failure of the government agency offers a possible veto by U.S. President Barack Obama , in the next 60 days, a period in which Samsung can continue selling their products.

The ruling is the result of the lawsuit filed by the California company against Samsung in 2011 , as part of a long battle waged patent business in a dozen countries, the two giants technology.

week early and concerning other parallel demand, the government of President Barack Obama announced his veto of a ban on the sale and import of some iPhone and iPad models in the United States, imposed in June by ITC itself after considering that these products infringe a patent Apple Samsung.

ITC decision vetoed by the White House had been a major victory for Samsung , who filed a lawsuit against Apple in June 2011 for violation of its patents.

I would like to live in a country where an astronomical phenomenon whose study belongs to the scientific field, such as the Perseids this is not “baptized” with the seemingly “harmless” and “nice” name tears San Lorenzo.

When will we begin to rid the language of the Catholic religion superstitious?

________________________

‘s funny you do not mind the name of the constellation from which the meteors appear to start, and that the name of this rain: Perseus, demigod of Greek mythology.

And, as you probably know, the phenomenon is known since long before it was known that it was dust trail of a comet, so it is quite normal to have a popular name associated with some event or date of Catholic tradition . In this case, day happen around San Lorenzo. But some do not you stay quiet if you do not seek to split hairs.

If you look forward, you’re free to call it “tears of the otter” or “periodic meteor rain 25 Thermidor”. But do not be surprised if nobody understands you.

Apple succeeds in blocking the U.S. import some products ... - The Mundo.es

new chapter in the war of patents that Samsung and Apple faces. The Californian company got the International Trade Commission (ITC) ban U.S. imports of Samsung devices to the U.S. but exempts the South Korean company for the prosecution in four cases .

However, this decision could end up being just a symbolic victory for Apple than just harm the business of Samsung . The implementation of the measure was automatically postponed pending a case review by the Obama administration, the newspaper The Wall Street Journal.

This failure is the result of the lawsuit filed by the California company against Samsung in 2011, as part of a long commercial patent battle the two computer giants.

After months of investigations, ITC concluded that Samsung violated two patents of Apple. A case is related to touchscreen technology and the other is connecting headphones .

However, Samsung said that does not violate Apple patents in their smartphones and tablets. If U.S. authorities check this, the import ban would be lifted .

also the South Korean company has appealed and expects as U.S. President Barack Obama, the go . “We will take all necessary measures, including legal action, so that our requests are reflected in the ruling,” he explained in a statement Samsung, world’s largest maker of smartphones.

White House vetoed the weekend after a trial of Samsung against Apple for a suspension on imports for some older models of iPhone and iPad.

However, unlike Apple, Samsung appealed to the ITC to patents that belong to the base of technological standards. The U.S. government and the European Commission are against selling bans patents based on these standards.

Rain shooting stars for the weekend - The País.com (Spain)

celestial prognosis is good this year to observe the Perseids, shooting stars in this year Apoca abound in the night sky. The light of the moon, a crescent, it will detract from the show because it will be hidden soon. The best night for viewing will be from Monday to Tuesday next, but Sunday should be seen in the sky the meteors. “With a little luck you may see a shooting star per minute, on average,” announces Robert Naeye expert in Sky & Telescope magazine . The International Meteor Organization predicts a maximum of racing. To enjoy the night observation of this phenomenon is recommended to seek a very dark sky (without annoying city lights), pollution-free and highly visible, no need any special equipment to see the shooting stars, only eyes adapt the dark and wait. Perseids can be seen all over the sky, but preferably in northeast direction, toward the constellation Perseus.

shooting stars “are small dust particles of different sizes, some smaller than grains of sand left by the comet along its orbit around the sun,” say the experts at the Institute of Astrophysics of the Canary Islands (IAC ). “When a comet approaches the inner regions of the solar system, its core, composed of ice and rock, is sublimated by the action of the sun’s radiation and generates the characteristics tails of dust and gas, the resulting particle stream dispersed by the comet’s orbit and is crossed every year by the Earth on its journey around the Sun, “they add. “During that meeting, the dust particles disintegrate at high speed when entering the Earth’s atmosphere, creating light trails known that meteors are called”.

For the Perseids-each year in mid-August are 109P/Swift-Tuttle comet debris. Particles (with sizes ranging from a grain of sand to a pea) enter the Earth’s atmosphere (about 130 miles high) at a speed of 60 kilometers per second creating traces of incandescent gas, says Sky & Telescope .

109P/Swift-Tuttle comet, which returns to the vicinity of the sun every 133 years (the last time it did in 1992), has a large core of about 26 kilometers in diameter, compared with other objects of this type, so that leaves lots of debris in space. Obviously, the Perseids were especially abundant in the nineties, after the visit of the comet, but the following will not occur until 2122.

Enjoy the tears of San Lorenzo - Reuters

MADRID, Aug. 10 (CHANCE) –

class=”c3″>

On the morning of August 12 can enjoy the Perseids shower of tears of San Lorenzo . When we refer to the Perseids we mean the meteor shower with high activity . The Perseids name is because their radiant is in the constellation Perseus.

While most meteor showers are the ‘shooting stars’ rain San Lorenzo is the most popular and observed in our hemisphere. This is because in this month the weather is nice and people take to the streets and it is a holiday period for many. Another curious fact is that occurs every year but usually has its peak from 10 to 13 August.

The only advice I give is that if you want to observe this phenomenon away from urban centers and move to the countryside . This is because artificial light city remove all visibility to be appreciated with vivid clarity and detail.

class=”c3″>

says the best way to witness this meteor shower is with the naked eye . You do not need binoculars or telescopes, simply being in a place with a wide view of the sky, away from bright lights.

The IAC also tell us that shooting stars are small dust particles of different sizes ranging leaving comets around the Sun In the case that one of these comets approaching the regions of the inner solar system, its core composed of ice and rock, is sublimated by the action of solar radiation and thus create dust and gas tails.

At that meeting, the dust particles disintegrate at high speed in the general atmosphere and well known light trails called meteors.

Discovered coronavirus antibodies in dromedaries Saudi ... - The Mundo.es

somewhere near Saudi Arabia and at some unknown point, a new type of coronavirus jumped from one animal species to humans. That respiratory virus, which has already affected nearly one hundred people in Arabia and neighboring countries (causing 43 deaths) is still a big mystery to the scientific community, that craves source. A new Spanish study indicates collaboration now that camels may have played a key role in the chain transmission of this new virus of animal origin.

The study, published in the journal The Lancet Infectious Diseases’, has discovered new coronavirus antibodies Omani Saudi camels, but also, to a lesser extent, in animals of the Canary Islands, imported from Africa to Spain nearly two decades ago.

ELMUNDO.es

explained Gortázar-Christian Schmidt, specialist Research Institute of Hunting Resources Ciudad Real (CSIC-Universidad de Castilla-La Mancha) and one of the authors of the study, this means that the animals have been contact the Saudi coronavirus or a similar pathogen in the past. Even as he insists, have been found only antibodies, not the virus itself, so we must continue working to identify the origin of this new infection.

Although antibodies were sought Middle East Respiratory Syndrome (MERS-CoV) in other animal species, such as goats, llamas, alpacas, cows and sheep, none of them showed signs of having been in contact with the coronavirus in the past (total of 49 samples were analyzed cattle from Oman, Spain, Holland and Chile). In the case of camels, 100% of animals originating in Oman had antibodies to the virus, compared to only 14% of animals tested canaries (other species analyzed in Spain, like goats or cows, were negative).

Coming from Africa

“ two packs are in captivity , for tourism purposes, which were imported from West Africa to Spain 18 years ago,” continues the Spanish researcher, “it is likely that even then bring in copies the antibody in your body, but that low percentage suggests that in all this time have not been exposed to the virus. ” Therefore, stresses, these animals pose no risk to humans, because they have the infection. Any traveler who goes to Saudi Arabia, where there have been most of the 94 infections (the cases of France, Germany, Italy and the UK had been in the Arab region), has more risk than a tourist camel stroll Canaries. In a commentary in the same journal, Emmie de Wit, U.S. NIH, highlights the curious fact that Oman has not registered any case in humans to date.

Despite the importance of finding remains unknown original source coronavirus, although it could be bat because recent studies have shown that the virus replicates in these animals easily.

However, as supported by the Spanish research, work with Arab countries are not just providing access to the field to find the source of MERS-CoV. The hypothesis Gortázar-Schmidt holding the bat is that the camels would have jumped and a process for preparing these animals for human consumption (which is common in Arab countries) a virus aerosol have infected a person by the respiratory route. The direct transmission to humans muriciélagos is virtually ruled by the nocturnal behavior of these mammals.

Being an animal virus, concludes the Spanish scientist, not fully adapted to the human respiratory system, so its spread among people of time is reduced (so far only been given to health care workers or a close contact with an individual). The World Health Organization (WHO) and scientists monitor squarely world through the MERS-CoV to prevent acquiring the necessary mutations that facilitate the spread between humans.

The work, which also participated Carlos Gutierrez, professor, University of Las Palmas de Gran Canaria, was led by Chantal Reusken, the Netherlands Institute for Public Health.

The camels could be the origin of the new coronavirus - The País.com (Spain)

less than a year in the UK discovered a new strain of coronavirus, very similar to that caused SARS (severe acute respiratory syndrome), without scientists figure out how consiguieran had mutated to jump to humans . The so-called MERS-CoV (coronavirus respiratory syndrome in the Middle East), originally from the Arabian peninsula, has so far been detected in a hundred people and caused more than 40 deaths. A study published Friday in The Lancet Infectious Diseases could clarify the origin of transfer: when analyzing blood samples of Omani camels, animals are widespread in the area of ??the outbreak of the infection, scientists have discovered the presence of antibodies against MERS.

The dromedary is a very popular species in the Middle East, where it is used to move, but also consumed their flesh and milk “

Recent research revealed that the new coronavirus could replicate in the cells of the bat, but scientists were skeptical about the possibility that this animal was responsible for transmission because of its secretive nature and lack of proximity to the humans. An international team of National Institute for Public Health and the Environment (Netherlands) has collected and analyzed 349 blood samples from different animal species, camels, cows, sheep and goats, among others, from various countries -Chile, Spain, the Netherlands and Oman, with the aim of identifying the head of contagion.

Google Play Music All Access comes to Spain to fight with Spotify - Ideal Digital

Google has launched its music service Google Play Music All Access in Spain. The truth is that it comes quite late, specifically with regard to the United States go with almost two years of delays since there the service was launched in November 2011.

But not only is the delay with respect to the United States of Google music service, it is that all the protagonists of the film “Enjoy a great online music library” and reached the party for quite some time and continue the analogy, one could say that Google comes when the party seems to already running out.

Although one of the first services to offer free online music was Grooveshark, the service at least in Spain has been a revolution and most successful was undoubtedly Spotify . With its large music library, from which you can enjoy for free (with certain restrictions), got in Spain the country of “all free” was implanted in a overwhelming.

After Spotify, at this event have been arriving as weight other guests were Amazon, Apple and more recently Microsoft with its Xbox Music service integrated into Windows 8. The truth is that really true competitor Spotify is equal Microsoft service because it is the only one that allows us to enjoy a great music library without checking exchange for having to listen to commercials and have a limitation in the listening time. This Google Play Music All Access really is not comparable because although it has a free service is very limited compared to free services from the competition.

According to the search engine company service is defined as follows: “Google Play lets you discover, play, store and share your favorite music online easily or Android devices. With Premium, you can listen to millions of songs without limits, create custom radio stations and music jump you do not want to hear.

First vaccine effective antimalarial - The País.com (Spain)

Researchers at the National Institutes American Health (NIH) have created the malaria vaccine more effective so far. In a phase 1 clinical trial, which in principle is only intended to evaluate the safety of treatment, none of the six volunteers who received five doses has contracted malaria after a year, in comparison, of the six volunteers who received placebo, five contracted the disease, and those receiving lower doses showed intermediate protection. Numbers are small but significant and hopeful. The vaccine is far from perfect, as it requires at least five intravenous injections, but the main specialists consider it a major breakthrough.

Malaria kills about 2,000 people a day, according to the latest estimates from the World Health Organization (WHO) with data from 2010. Current vaccines have limited efficacy, and the search for a drug that offers good protection against infection has been a nightmare for researchers for nearly half a century.

The only method that offers a truly effective and lasting protection, known to scientists for 40 years, is actually the work of Mother Nature. The main causative agent of malaria is the single-celled (protozoa), Plasmodium falciparum, which is transmitted to humans by the bites of mosquitoes of the genus Anopheles. But there is a plasmodium, called sporozoite, which infects the salivary glands of Anopheles, and when you let the mosquitoes bite to healthy people, they are permanently protected against pathogenic forms of the parasite. This is the key that has allowed us to develop the new vaccine.

The disease kills about 2,000 people a day in the world

Robert Seder, the

Much remains to be done, but it seems paved the way for a breakthrough

“The results indicate” according to the authors, “there is a threshold dose-dependent immune to establish a high-level protection against malaria, and that this threshold can be achieved by intravenous administration of a vaccine that is safe and meets with health regulations. ” A single force protection that had achieved so far with the old method of mosquitoes, a strategy that would be more difficult to implement even the five intravenous doses.

In any case, scientists admit that much work to be done to clarify beyond a year, how long the protective effect: if one were to inject five times a year for the entire population for the rest of his life, technical and economic obstacles would be formidable. Even if enough with injections of the first year, the fact that they are injecting, rather than the usual intramuscular, intradermal or nasal-would be a challenge for health systems in poor countries affected.

But the way seems open for a health breakthrough of extraordinary importance.

EMILIO DE BENITO class=”autor”>

Few people in the world better able to assess how difficult it is to get a malaria vaccine that Pedro Alonso. This researcher, alternating his work between the Centre for International Health Research (CRESIB, funded among others by ISGlobal) and Africa-serving COUNTRY from Maputo, capital of Mozambique, has been in recent years the biggest star of this field with a job you got, among others, the support of the Bill and Melinda Gates Foundation. But after a promising start, the last tests of its prototype, with protection rates of only 31% in children, put a shadow on his work.

Despite this disappointment, Alonso is full of praise for the work of Hoffman and his team. “It is very positive. I’ve known them for 20 years and have worked with them. The key point is the proof of concept that you have to work, “he says.

refers to the idea of ??this new vaccine model uses an idea “that was used in the sixties and seventies, but it proved unfeasible”. Then sporozoites were not used (one form of the plasmodium that causes malaria) irradiated to weaken, as now. “He radiated mosquitoes, but was stung when the immunized people,” said Alonso.

But that was not feasible. “Hoffman has started from the idea, but instead of using mosquitoes, has managed sever their salivary glands, which is where the parasite, and remove it. And has gotten in a protection group six six, which is a full protection. “

The drawback is that the method is very applicable in the field, and from someone who has spent decades in Africa, the continent most affected by malaria. “So I say it is a proof of concept to be refined.”

There are two main drawbacks: first, that the system that has given the best results you need five intravenous injections, “a much more complicated than a pill or intramuscular injection. We must reduce the dose, seek new routes of administration, “says Alonso. The second is that parasites thus obtained must be kept at 200 degrees Celsius, “liquid nitrogen”, a technique that involves handling and storage problems.

Alonso, however, is optimistic. “I recently spoke with Anthony Fauci [director of NIAID, National Institute of Allergy and Infectious Diseases of the United States], and the expectations and enthusiasm are at 100%.” ??

Bernardo Hernandez passes Flickr - Computer World Spain

Spanish entrepreneur Bernardo Hernandez has been appointed as chief executive of Yahoo Flickr, as announced on Twitter.

Flickr has new director. Spanish is the Bernardo Hernández , a leading Internet entrepreneurs and investors in our country. Hernandez, who was global head of consumer product marketing for Google, left the company in search of new projects and has been now when, who was his companion in Google, Marissa Mayer, has chosen to lead Flickr.

Bernardo Hernandez was one of the creators of Idealista.com, 11870, FloresFrescas and Fever. It was also StepOne driver , a platform to help start-ups to settle in the United States, and even investor and chairman of the social network Tuenti until its sale to Telefónica .

In 2005 he jump class=”c6″> Spain as marketing manager and went on to the United States as director of global marketing Google Maps and Google Earth. His career within this great company led him to his most recent position as CEO of Zagat, a restaurant guide that Google bought in 2011.

May this 2013, Hernandez announced on Twitter his departure from Google without clear direction and has also used the microblogging network to communicate its new role in Flickr .

The sun changes its north - The Mundo.es

Sun’s magnetic field will reverse in the coming months

In the next three to four months, the sun’s magnetic field, which bathes the Earth and all the planets of the system, complete polarity reversal, a process that occurs every eleven years, the space agency reported today U.S. NASA.

“This change will impact in the entire solar system,” said solar physicist Todd Hoeksema, Stanford University, in California, speaking for NASA.

reverse polarity north-south pass and vice versa occurs at the culmination of each solar cycle , when the sun’s inner magnetic reorganizes.

During this phase, which physicists call Solar Max , rashes can increase energy cosmic rays and ultraviolet radiation reaching the Earth, and this can interfere with radio communications and affect global temperature .

Hoeksema is director Wilcox Solar Observatory at Stanford, one of the few in the world studying the magnetic fields of the Sun and have observed this phenomenon since 1976, a period in which investments have been three. Phil Scherrer, another solar physicist at Stanford, said that what happens is that “the Sun’s polar magnetic fields weaken, remain at zero, and then emerge again with the opposite polarity.’s A normal part of the solar cycle.”

solar magnetic influence, known as the heliosphere , extends billions of miles beyond Pluto, and even capture the Voyager probes, launched in 1977 and now hover around the threshold of interstellar space.

WhatsApp adds voice messages - The País.com (Spain)

“We want to be the twenty-first century communication,” insists a spokesman for the California company to announce the news. WhatsApp is updated and like their top competitors, and Line WeChat allows voice calls.

is true that already could send voice messages as notes, ie was asynchronous communication. This is more like Viber or Skype, also at Google Hangouts. Calls are included within the one-dollar fee (about 79 cents) a year to charge for its use.

The operation of this new option improvement over existing voice notes. The mechanics are very similar to a walkie-talkie: you press the record button while talking and sent to lift your finger. When you receive a message, just download, the weak point of this new-and heard. It is fast but not enough to be a natural and fluent conversation.

“This new option allows you to communicate in real time with friends or family, are in the next room or thousands of miles away,” said El Pais through posts by Whastapp. The service will be installed gradually in the next 24 hours on all platforms it works: iOS, Android, Windows Phone, Nokia and BlackBerry.

talk option adds to the announcement of figures which will surely be multiplied after the improvement. Every day more than 11,000 sent millions of messages and received more than 20,000. The photos continue to reign, are the most sent: 325 million photos shared every day.

company with only 45 employees, has more than 300 million active users worldwide. Spain is a country star, exceed 20 million monthly active users. As in Germany, Mexico and India.

Despite its success, its implementation is very irregular and not the first global messaging service, according to GlobalWebIndex, which measures the use of these applications between, according to them, the 969 490 million smartphones that exist in the world.

This index considers instant messaging services such as Google Maps, then, is the number one ranking, being used by 54% of the population with smartphone. Ovi Maps to Nokia is used by the 9% and 11% ranked. Apple Maps gives no data.

The second would be for Facebook, with 44% and the third, YouTube (35%), followed, surprisingly, G+ (30%). The first application pure and instant messaging only for Weixin / WeChat, in fifth place, with 27% of users thanks to its presence in China, Hong Kong and Malaysia.

sixth is for Twitter (22%), followed by Skype and Facebook Messenger. Ninth place is already in use WhatsApp, implanted in 17% of smartphones. And the tenth to Instagram (11%), also owned by Facebook. Its direct competitor in videos, Vine, is ranked 17th, with only 2% of respondents answered that they have used in the last month ..

Spanish is the Bernardo Hernandez, who was head of the prestigious hotel and restaurant guide Zagat and will direct the Flickr photo sharing service.

executive announced his own Twitter account. Hernandez’s signing is not a surprise, because it is known that Mayer had it in consideration for some time. Flickr is currently undergoing a process of change to remain relevant towards service mobile applications like Instagram.

not long since Yahoo! introduced a new design of the website and has been provided with new tools to increase their appeal and functionality.

A cherry planet outside the Solar System - The Mundo.es

Using data

infrared Subaru telescope in Hawaii, an international team of astronomers have photographed a giant planet around the star ‘GJ 504′. Several times the mass of Jupiter and of similar size, the new world, called ‘GJ 504b’, is the lowest-mass planet ever observed by direct imaging techniques that orbits a star like the sun .

“If we could travel to the giant planet, we would see a world still glowing from the heat of his training color reminiscent of a black cherry , a magenta color,” says Michael McElwain, one discovery team member from NASA.

According to the most widely accepted theory, Jupiter-like planets have their onset in the gas surrounding a young star. A core produced by collisions between asteroids and comets provides a seed and, when this core reaches sufficient mass, its gravity quickly attracts gas from the disk to form the planet.

“This is one of the planets most difficult to explain within a framework of traditional planet formation,” said team member Markus Janson a Hubble postdoctoral fellow at Princeton University in New Jersey. “This discovery means we have to training seriously consider alternative theories , or perhaps re-evaluate some of the basic assumptions of the core accretion theory.”

Direct imaging is probably the most important technique for observing planets around other stars, but also the most difficult.

“This technique provides information about the planet, luminosity, temperature, atmosphere and orbit, but the planets are so weak and so close to their parent stars is like trying to take a picture of a firefly near a lighthouse “says Masayuki Kuzuhara at the Tokyo Institute of Technology, director of the research team of the publication ‘The Astrophysical Journal’.

exoplanets, ie planets outside our solar system, they are of many types. If in recent years it has discovered an exoplanet dark as coal or other small and rocky, a team of international astronomers has now photographed a giant planet around the bright star GJ 504, which, however, is the lowest-mass planet ever detected outside our solar system and magenta .

exoplanet, dubbed GJ 504b , has four times the mass of Jupiter . It orbits a star nearly nine times the distance Jupiter orbits the Sun, which poses new challenges theories about how giant planets form. To capture it, astronomers have used direct imaging, the infrared data Subaru telescope in Hawaii .

Planet GJ 504b has a temperature of 237 degrees Celsius, while the star around which orbits a little warmer than the Sun, is 57 light years away. According to astronomers study, published in The Astrophysical Journal , an estimated system has about 160 million years , based on methods that connect the color of the star and the rotation period to age, NASA has revealed in a statement.

“If we could travel to the giant planet, we would see a world glowing with color reminiscent of a cherry blossom dark , a magenta color,” said a team member at NASA Center Goddard Space Flight, Michael McElwain, who stated: “Our near-infrared camera reveals that his color is much bluer than other planets photographed, which may indicate that its atmosphere has less clouds “.

New Challenges in theory formation of planets

According to the most accepted theory, known as core accretion model, Jupiter-like planets begin to disk debris rich gas surrounding a young star. A core produced by collisions between asteroids and comets provides a ‘seed’. When the core reaches sufficient mass, its gravity attracts disk gas to form the planet.

This model works well for planets that are in place in the orbiting Neptune. The magenta exoplanet GJ 504b, is located at a projected distance of 43.5 astronomical units from its star. The actual distance depends on the inclination with respect to our line of sight, which is not precisely known.

“This planets is one of the most difficult to explain in the context of planet formation traditional “, explained team member and postdoctoral fellow at the University of Princeton, Markus Janson. “This discovery means we have to seriously consider planet formation theories alternatives, or perha ps reevaluate some of the basic assumptions of the core accretion theory”, has topped.

The research is part of the exploration of exoplanets and disks with the Subaru telescope (SEEDS), a project to directly image extrasolar planets and protoplanetary disks around several hundred nearby stars. The project began in 2009 and is directed from the National Astronomical Observatory of Japan.
