Found a new species of beetle in the deepest abyss … – RTVE

VICKY BOLAÑOS

Two researchers from Spanish universities have described a new species of beetle that lives in the deepest cave in the world . The insect has been baptized Duvalius abyssimus and have it located in the cave of Krubera-Voronia, in the western part of Georgia, bordered by the Black Sea.

The study of this new species was published in the journal Zootaxa, and is signed by the researcher at the Universities of Aveiro and La Laguna, Portuguese Ana Sofia Reboleira and zoologist at the University of Alcalá, M. Vicente Ortuño .

As explained to RTVE.es Vicente M. Ortuño, specializing in underground Biology, continually finds new insects in these habitats (called hypogea, ie passages underground) and recently in the depths of the Sierra de Guadarrama or the Moncayo.

Voronia, habitat complicated access

However, this finding Concrete is striking since it has been found in a cave whose entrance features enormous difficulty . Voronia, located in the mountains of Arabica, this is a chasm vertically to a depth of 2140 meters .

Also, in this part of the Caucasus converge Asian and European tectonic plates and has great biogeographical interest , as indicated Ortuño.

has also told the investigating Ana Sofia Reboleira and another colleague were those who made the collections of material, both inside and outside the cave, located 15 kilometers from the sea.

The newly discovered beetle

As collects Sync, researchers have only two copies of Duvalius abyssimus , a male and a female, collected in the cave but “not located in the final meters.”

Gender Duvalius is a successful colonization of terrestrial depths. Most species have a life style and hipogeo live in caves or in the shallow subsurface environment .

“The characteristics of the new species is indicated by average degree of adaptation to life underground . Proof of this is that it still has eyes that are absent in the highly specialized cave species, “added the researcher.

underground

The Scientist University of Alcalá, who practiced biospeleology , commented that specializes in this insect group, which has spent the last ten years of his career.

“Exploring the subsurface environment means must move in a hostile environment , like in the mountains or on the seabed.’s not the natural environment of humans, so it requires break fears, “stated .

So, aphotic media works, which does not get a hint of sunlight. “It’s an absolute darkness , and under these conditions seek such small animals is difficult, since they live in small cracks and crevices and you have them out. We use small baits and traps that leave a more accessible place and return to pick them, “he explained.

Detect a possible signal of dark matter – La Vanguardia

Madrid. (EP) -.’s (ESA ) Chandra X-ray Observatory NASA and the XMM-Newton European Space Agency have detected a possible dark matter signal , the mysterious and invisible substance that makes up most of the material universe.

Specifically, the two ships saw a peak X-ray emission from over 70 different clusters of galaxies. While the origin of the X-ray remains unclear yet. Could be generated by the decomposition of some type of dark matter particles, as pointed out by scientists.

“We know the explanation of dark matter is a long shot, but the payoff would be huge if we reason, “noted the study’s lead author Esra Bulbul, who pointed out that both teams will” continue testing this interpretation “to see” where it takes you. “

Dark matter is so named because neither absorbs nor emits light, so it is impossible to observe directly. Still, astronomers know that it exists because it interacts gravitationally with normal matter , which can be seen and touched.

In fact, it is believed that dark matter accounts for over 80 percent of all matter in the universe. What is missing in this theory is to know exactly what is dark matter. Over the years, experts have proposed a number of exotic particles as candidate components of dark matter , including weakly interacting massive particles (WIMPs), axions, sterile neutrinos (a hypothetical type of neutrinos emitted X-rays when it decays).

It is possible that the signal observed by Chandra and XMM-Newton has been produced by sterile neutrinos, as researchers have pointed out, but at the same time, have recognized that is far from a sure thing.

“We have much work to do before we can say with certainty that we have found sterile neutrinos , but the possibility has us excited,” stated another author of the study, Maxim Markevitch.

Normal matter in galaxy clusters may also have been responsible for the issue, but this interpretation does not fit well with current thinking about galaxy clusters and atomic physics of hot gases.

“Our next step is to combine data from Chandra and Suzaku mission of the Japan Aerospace Exploration Agency (JAXA) to see if we find the same points of X rays in a large number of galaxy clusters “, scientists have pointed to this research, which was published in The Astrophysical Journal .

The robot ‘Curiosity’ celebrates its first Martian year – La Voz de Galicia

After one Martian year, or 687 Earth days, the robot Curiosity NASA has done its homework. The rover which started on 26 November 2011 in an Atlas rocket and arrived August 6, 2012 to investigate the mysteries of the red planet, Mars has shown that hosted a day conducive to house life. This finding was made possible by the concave basins, fan-shaped deposits, linear, lobed morphologies and moraine remains were found and reveal the existence of ancient glaciers .

“The crater was covered by glaciers about 3,500 million years ago,” explains scientist Astrobiology Center and Cornell University in the U.S., Alberto Fairén. The lead author of the research adds that at the time “was also rivers and lakes with very cold liquid water in areas of lower elevation within the crater»

Because of these great finds, Curiosity has gained more time on Mars. Although his mission was scheduled for one Martian year, NASA has confirmed continue their work while the vehicle’s tires can cope with the terrain . And the wheels have already been damaged at this time due to their long runs during the 600 days Trip the closest planet to Earth.

On the other hand, this is also the first time a joint past climate of Mars solution is provided, since, according Fairén, “explains while geological traces of the former presence of liquid water covering entire planet and climate models have shown that Mars was never a warm planet ‘. Follows in the case of the Gale crater, which was excavated by the impact of a large meteorite some 3,600 million years ago, which was covered with glaciers shortly after. “It is possible that the impact area was already covered by glaciers before the collision,” says the researcher, who adds that the combined energy of impact with the surface ice “is what might have generated even hydrothermal areas”.

A lake with brackish water

During the 7.9 miles you traveled Curiosity 23 days in their movements, the robot also has two stone slabs located in a zone near the crater Gale in Yellowknife Bay, which perforate after discovered that the place was “a bed of a lake with water moderately brackish, elemental ingredient for life, although not suitable for drinking, “says NASA. The vehicle, which weighs about 900 kilos and is equipped with cameras, sensors and clamps, demonstrated by measurements of the variations between the heavy and light elements in the Martian atmosphere disappeared said atmosphere processes that favored the loss light atoms .

The study published in the journal Planetary and Space Science using images captured with CTX and HiRISE orbiter cameras Mars Reconnaissance Orbiter NASA. These pictures show, for example, that the Breiðamerkurjökull glacier in Iceland is “very similar” to the crater Gale explains Fairén. There are other terrestrial glaciers Mars counterparts to systems such as the Malaspina in Alaska and other northern Canada and Antarctica.

The next target Curiosity will investigate Mount Sharp , but has previously made a stop to drill and collect a sample from a sandstone area called Windjana, interesting to scientists because it contains more magnetite than previous samples that have been made to analyze on the surface of Mars. “It is too early to draw conclusions, but we hope that the results of future research in Sharp help us better understand the merger of Martian rocks, ‘says one of those responsible for the mission scientist John Grorzinger.

Reports about the next generation iPhone will not cease to grab headlines. The latest one comes from the hand of publication Bloomberg has confirmed that an anonymous source Apple plans to begin production of the iPhone 6 in the month of July. Contrary to numerous reports have indicated that to date, source Bloomberg says the company will start production model 4.7 inch and 5.5 inch simultaneously.

However, although the production of both models begins, the source has anticipated Bloomberg is possible that the 5.5-inch model is not able to meet demand in the first cycle sales. The source happened to note that the production process for the 5.5-inch model is not as efficient as that of the 4.7-inch model with which as the process is not as efficient production will be lower.

As for the form factor, power Bloomberg stressed that both new models will be more rounded and thinner that the current generation of iPhone 5s. As for the internal specifications, the source has not gone into detail. In any case it is estimated that in addition to changes at the level of the screen, the next iPhones also come with improvements in the section of the camera, processor and supposedly on the same sensor Touch ID.

It is expected that new iPhones are presented in October, possibly including the launch of the rumored smartwatch company. Pricewise, it is estimated that 4.7 inch model will cost 100 dollars / euros more than the current iPhone 5s. However, these estimates were provided by analysts and today should not be taken very seriously

Higgs boson is more than ever – La Voz de Galicia

Higgs boson is more than ever. The elusive God particle finally hunted in late 2013 in the Large Hadron Collider (LHC) after its existence was predicted theoretically 50 years ago by Higgs, Englert and Brout, behaves more and more of a completely identical which was described by physicists who last year finished getting the Nobel.

The Higgs boson, the particle that gives mass to the other and key part of the standard model physics, which explains how it is and all known matter is formed, also decays into fermions, the building blocks of matter, among which are the different types of quarks and leptons. The discovery, which was made in Physiscs Nature , is the result of new data from the LHC’s Atlas experiment.

So far only had decomposition observed in other bosons, the carrier particles of the various forces of nature, but noted that the theory could also decay into fermions, the building blocks of matter. And this is just what has been proven now.

“may seem an insignificant detail to ordinary mortals, but it is a huge step forward. Now we know that particles such as electrons get their mass through the Higgs field, which is really exciting, “explains Markus Klute, Massachusetts Institute of Technology and director of the study. “This is a huge step forward,” says Professor Vincenzo Chioccia, Institute of Physics, University of Zurich, who has analyzed the data. There is not any doubt that Higgs boson is.

The ship ‘Rosetta’ will explore the origin of water on Earth … – The País.com (Spain)

id=”cuerpo_noticia”> How is the structure and composition of the nucleus of a comet? Did you bring the water to make the planet Earth? Could they also bring the precursor molecules of life? How does the activity of comets work when close to the Sun? These are the fundamental questions that seeks to answer the Rosetta spacecraft , the European Space Agency (ESA) , summarizes Laurence O’Rourke, coordinator of scientific mission operations. And his colleague Michael Kueppers adds that “comets are made of the same material that formed the plan, but raw, so studying them can learn a lot about how the solar system formed.” The Rosetta , after nearly a decade of traveling from that left Earth, is already nearing its final destination, the comet 67P/Churyumov-Gerasimenko currently about 600 million kilometers from the Sun The meeting is scheduled for next August 6th.

Last January the ship, who had traveled for two and a half years in hibernation, with almost every team was activated off, and scientists have checked as all data collection instruments and analysis, as well as cameras, work perfectly, yesterday reported its leaders at a meeting in the European Space Astronomy Centre (ESAC) , the ESA headquarters in Madrid, which will handle scientific mission operations.

A dozen comets and asteroids have been visited and satellite recalled Kueppers. But Rosetta will be the first probe to orbit the nucleus of one of these celestial objects and accompany him on his journey to the vicinity of the Sun carries cameras with a resolution of 10 centimeters and instruments (11 in probe and 10 at the Philae lander ) for direct investigation of the comet. Data 67P/Churyumov-Gerasimenko water composition (Comets are balls of ice, rock and dust fragments) should help understand their relationship to the water on Earth, Kueppers said. “It might even bring comets molecules formed life … it is a hypothesis,” he added. “Rosetta will also help interpret the data we have from other comets,” he said Nicolas Altobelli, mission scientist

” comets may even bring it formed molecules that life is a hypothesis … “

Throughout the month of August, once passed the various operations braking is doing these weeks to ship not be long the comet will begin a complex spatial maneuvers to go dancing closely watching 67P/Churyumov-Gerasimenko, about four kilometers across. “We can not put the ship in orbit directly, so Rosetta will remain, at first, a little away from the comet ” said O’Rourke. Turning their engines perfectly timed moments, doing flybys will probe the target from different angles for a month. And all this at a distance from the earth such that the signals from the spacecraft, traveling at the speed of light (about 300,000 miles per second), will take 20 minutes to reach Earth.

The September 11 will ship at last comet’s orbit and later that month will be spinning around at 20 miles high, to fall to about 10 miles in mid-October. A month later even closer to 67P/Churyumov-Gerasimenko to release the Philae module that descend to the nucleus of the comet. There, this artifact hundred kilos must run at least a week with power from its battery, and then up to three months with its solar panels experts said. The landing will be decided with maps of the surface of cometary nucleus that will be done with the data you send Rosetta spacecraft from August.

A computer can overcome first Turing test – The World

able to ‘chat’ as a 13 year old boy has become the first machine has passed the so-called Turing test . In an experiment conducted at the Royal Society London, five computers were used to try to see if they could fool many people into believing they were human beings of flesh and blood during a conversation with text messages.

This test was conceived in 1950 by the great mathematician and computer pioneer Alan Turing , who said that if a machine could not be distinguished from a human, would show that he was capable of “thinking”. Since then, the Turing test, a man who contributed decisively to the Allied victory during the Second War Mundia, as logró decipher the codes used by the Nazis to send encrypted messages-has been considered the key test to verify that a computer has ‘artificial intelligence’.

So far, no machine had passed this test , which requires that 30% of their human partners believe they are talking to another person during conversation (by exchanging texts) five minutes.

But as reports the University of Reading a statement , the ‘Eugene Goostman’ computer program designed to simulate the brain of a 13 year old boy, for the first time managed to convince 33% of their human partners was a person.

“In the field of artificial intelligence, there is no more iconic and controversial than the Turing test milestone.’s very appropriate that such an event has been achieved in the Royal Society of London, the great seat of the British science and the scene of many of the great advances in the history of human knowledge throughout the centuries. This milestone will be one of the most exciting developments in the history of science, “said Professor Kevin Warwick , University of Reading, one of the organizers of the experiment.

The ‘intelligent’ machine was designed by Vladimir Veselov, a computer of Russian origin that works in the U.S., and the Ukrainian Eugene Demchenko, who lives in Russia.

“It’s an amazing achievement for us, and we hope to promote interest in artificial intelligence and chatbots [software able to hold conversations with people], “he declared an Veselov excited.

Warwick has acknowledged that in the past, previous experiments had allegedly failed to show that other machines could” think “, but has questioned its validity: “Our experiment was performed with simultaneous tests compare more than ever, is independently verified and conversations had no restriction A real Turing test does not set the questions or topics of conversation while they perform. the. therefore test we are very proud to say that the Turing test has been exceeded for the first time “.

British scientist believes that the existence of computers with remarkable artificial intelligence could have significant “implications for society” both positive and negative, as this may increase the risk of “cyber crime”.

The experiment in the Royal Society had a special historical value, since took place just as the 60th anniversary of the death of Turing was met, considered the “father” of modern computing.

However, despite the enthusiasm with which the authors of the experiment presented results, some experts have questioned. New Scientist , for example, has published a critical analysis titled ‘The “success” of the Turing test is not all it seems’ .

“The Turing test has become a symbol of machine intelligence, but this new experiment has only tested the ability of machines to chat . however, people are capable of much more. Human intelligence goes far beyond chat “concludes comment New Scientist .

Sherpa Next: the final version comes after a year in testing and … – 20minutos.es

After more than a year testing and a million users worldwide, the mobile voice search Sherpa Next , designed by a young Spanish entrepreneur to compete with Google and Apple will be available in its final version the next week on a free app on Google Play .

“This new technology breaks with everything on the market to combine personal assistant capabilities capabilities search engine and predictive capabilities , and all with a design and a unique user experience, “the company reported this week in a press release.

Sherpa , the number one voice assistant for Android devices in Spanish understand concepts and presents the search results in the most appropriate format, according to the company.

Sherpa Next is based on patented technology and natural language semantics combined with artificial intelligence not only based on words as the other search engines and will be available on June 11 for mobile phones with operating system Android (from Google), according to CEO and founder of Sherpa, Xabier Uribe-Etxebarria.

Next Sherpa is based on patented technology and natural language semantics combined with artificial intelligence, for understanding Machine-Man .

The system uses a semantic analysis five levels that evaluates the information according to different sources to provide a really useful result for the user.

The startup screen anticipates the information needs of the user according to his preferences and learn the user.

For example, if you are looking for information over a city the system provides data on population, weather, maps and other relevant.

On a football team , the latest results are provided, the site official website of the equipment and the latest news published.

Sherpa uses dynamic models search and HTML5 in its modular graphic interface, so that the information is easily accessible from mobile devices.

Searchable with questions and concepts of natural language. For example, if asked “How old is Mick Jagger?”, The response includes the age of the singer but also his biography, photos, music streaming and links to other “sites” with relevant information.

NASA sent the first video by laser from space – La Vanguardia

Madrid. (EP) -. NASA has sent the first video from the International Space Station to Earth via laser , this Thursday, June 5. This is the first official broadcast Optical Instrument Payload for Lasercomm Science (OPALS).

With a tribute to the first standard output of a computer program, and a nod to enthusiasm of the young team behind this new technology, the message and title of the video is. “Hello World”

The message went through the space between the ISS and Earth in 3.5 minutes long faster compared to the 10 minutes required to send messages by radio, said the U.S. space agency said in a statement

This technology demonstration is an important step in changing the way NASA will contact spacecraft in the future. Data transmission for optical communication is much higher than for radio frequencies.

High Speed ​​
scientific instruments used in space missions increasingly require higher communication speeds to transmit the collected data to Earth or to support applications of high-speed data transmissions such as HD video. Optical laser ommunications (Lasercom) is an emerging technology that the data is sent through lasers.

This offers the promise of much higher speeds than can be achieved with data radio frequency (RF) and has the advantage of operating in a frequency band that is currently unregulated. “Optical communications has great potential,” said mission manager Matt Abrahamson.

“Right now, many of our missions in deep space are reported in 200 to 400 kilobits per second. OPALS show up to 50 megabits per second and future optical communication systems will provide deep space over gigabits per second from Mars.

welcomes the CIA on Twitter stating that the agency will publish classified information

(IRIN) -.. The CIA, the American Intelligence Unit, launched yesterday its journey through Twitter . In one of his first messages thanking the good welcome they had received-his first tweet resulted in over two hundred thousand retweets, and promised much
declassified information sharing with their followers.

In the biography social network, the U.S. agency is defined as “the first line of defense nation . Met what others can not accomplish and we where others can not.”

The mood used by the CIA in its first two posts was attacked by Wikileaks -the international media organization that publishes sensitive information classified as secret, preserving the anonymity of their sources. His bio on Twitter reads “open governments” , a claim that can meet the objectives of the media organization.

replied to the tweet Wikileaks CIA saying that they in turn publish content with classified information about the agency. This message also includes several links that redirect to previous publications of Wikileaks on the U.S. agency, including documents on the stand war in Afghanistan , terrorism in the United States and finally a web address leading to a search within the page itself where over Wikileaks thousand related to the CIA results appear.

In less than 24 hours more than the sum CIA 355,000 fans of the social network with only two posts. Meanwhile Wikileaks, has more than two and half million of ‘followers’.

40 percent of the moon is from a planet that exploded … – Reuters

MADRID, 6 June (IRIN) –

A new analysis of lunar rocks that sustains our satellite born in a giant collision between Earth and a mysterious nascent large rocky planet.

Earth formed about 4,500 million years ago, and scientists think the moon was born shortly after . The prevailing explanation for the origin of the moon, known as the giant impact hypothesis is that it was the result of two colliding protoplanets: Earth formation and an object the size of Mars called Theia . A lot of debris eventually formed the Moon.

“The giant impact hypothesis is valid for explaining most of the features of the moon,” said lead study author Daniel Herwartz, isotope geochemical University of Göttingen in Germany

For example, a collision of this type could help explain why the moon is low in substances that evaporate fairly facility, such as water. “The reports of small amounts of water on the moon do not change that vision,” said Herwartz. “ Compared to Earth, the moon is still completely dry ,” he said.

However, scientists still have doubts about this idea because of the chemistry of the Moon . The giant impact models often say that the moon should be formed in approximately 70 percent of the remains of Theia. The problem is that most of the planets in the solar system have unique chemical signatures , and the Earth and its moon should also have them. However, the Earth and the Moon appear similar when it comes to versions of elements called isotopes.

CHEMICAL DIFFERENCES IN EARTH AND MOON SIGNATURES

• Se two step ahead of asteroids near Earth
• posible recent habitable environment on a volcano on Mars

Now, for the first time Herwartz and colleagues found differences in the isotopic composition of the Earth and Moon findings that support the giant impact hypothesis of how the moon formed

The researchers focused on two different ratios of oxygen isotopes -. oxygen-16, which has eight neutrons in its nucleus, and oxygen-17, which has nine. oxygen isotope ratios can vary greatly from one planet to another.

Initially, the scientists examined the moon rocks that the moon went flying by cosmic impacts and landed on the Earth as meteorites. However, these samples were contaminated by oxygen isotopes in the water on Earth .

However, Herwartz and colleagues observed lunar rocks provided by NASA were collected by astronauts during the Apollo missions. The researchers found that these rocks contain slightly more oxygen-17 to oxygen-16 compared with terrestrial rocks.

MOON IS IN A 40% THEIA

“The differences are small and difficult to detect, but they are there,” said Herwartz. “We now have an idea of ​​the composition of Theia.” The new data suggest that the moon can be made in about 40 percent of Theia . The researchers proposed that Theia was similar to meteorites known as enstatite chondrites.

“This group of meteorites has a very, very similar isotopic composition to Earth,” said Herwartz. “Such a composition of Theia explain why they had not detected oxygen isotopic differences or any other isotope system to date.”

Central Intelligence Agency American ( CIA ) Friday opened its own Twitter account with a touch of humor: “We can not confirm or deny that this is our first tweet” the message said .

This proverbial joke about his secrecy, the largest spy agency world opened its public account (@ CIA), after years of absence of this popular social network.

The CIA will be able to provide information about the history of the mission of the CIA and other issues

In his profile, the agency is defined as the first line of defense in the U.S. and says: “We accomplish what others can not accomplish and reach where others can not go.” With this movement the CIA seeks to approach the public beyond their public website and the official accounts and maintained in Flickr and YouTube , explained in a statement.

With the expansion platforms Facebook and Twitter, the CIA “ be able to participate more directly with the public and provide information about the history of the mission of the CIA and other issues” director John Brennan said.

Brennan said the CIA has “ important knowledge to share “. “We want to ensure that no classified information about the Agency is more accessible to the American public that we serve, consistent with our national security mission,” he said.

CIA continue to publish news , statements, and information about job openings on their website and the popular “World Factbook”, a tool for data geography and political situation of the countries of the world.

After the onset of CIA account on Twitter, the organization journalistic WikiLeaks also wanted to interact with the CIA .

In the second tweet from the government agency, the CIA hopes “share much no content classified with you “, to which WikiLeaks said they expected” unrated share great content about you. “

In addition, the text criticized WikiLeaks profile of the CIA (” Met what others can not accomplish and reach where others can not get “), saying that the CIA” seems boast of illegal behavior that others will not touch. “

Capture the ‘Eye of Sauron’ in the Cosmos – La Vanguardia

Madrid. (Writing and agencies) -. The instrument SPHERE (search for exoplanets with spectro-polarimetry of high contrast, for its acronym in English), installed on the VLT (Very Large Telescope) at Paranal Observatory ESO (Chile), has already captured its first image. Although much like the Eye of Sauron - the Evil Lord of the Rings – which has grasped this new gadget is one of the best ones so far achieved dust ring around the nearby star HR 4796A .

image not only shows the ring with exceptional clarity, it also illustrates how SPHERE can remove the glare of the bright star at the center of the image. This new tool for locating and studying exoplanets combines several advanced techniques.

In the early days of observation has been confirmed that SPHERE provides improvement over previous instruments, providing striking images of dust disks around nearby stars and other objects observed.

SPHERE has been developed and built by a consortium of several European institutions, led by the Institute of Planetology and Astrophysics of Grenoble (France) in collaboration with ESO. This instrument is intended to revolutionize the detailed study of exoplanets and circumstellar disks .

In December 2013, SPHERE overcame his trials in Europe acceptance, after which he was sent to Paranal (Chile). Delicate reassembly was completed in May 2014 and now the instrument is installed on the VLT Telescope Unit 3. SPHERE is the last of the second generation instrument for the VLT (the first three were X-shooter, KMOS UXO).

SPHERE combines several advanced techniques in order to offer the highest contrast ever reached in obtaining direct images of planets, far beyond what could be achieved with the NACO instrument, which took the first direct image of an exoplanet.

To achieve this impressive performance, develop technologies needed SPHERE novel since its inception, particularly in the areas of adaptive optics, special detectors and components coronagraphy.

“SPHERE is a very complex instrument. Thanks to the hard work of many people who participated in its design, construction .! and installation, has already exceeded our expectations, it’s wonderful, “says Jean-Luc Beuzit, Institute of Planetology and Astrophysics of Grenoble (France) and principal investigator of SPHERE

Objective.: find exoplanets

The main objective of SPHERE is to find and characterize, by direct imaging, giant exoplanets orbiting nearby stars. This is an extremely difficult task, since these planets are much closer to their parent star and are much weaker.

In a normal image, even under the best conditions, the starlight hidden completely the faint glow of the planet. Therefore, the whole design of SPHERE is focused on achieving the highest contrast possible on a small piece of sky around the dazzling star.

The first of the three novel techniques used by SPHERE’s extreme adaptive optics , used to correct the effects of Earth’s atmosphere in order to make the images sharper and increase the contrast of exoplanets.

Second, a coronagraph is used to block light Star and further enhance contrast. Finally, a technique called differential image using the differences between the starlight and the planetary light in terms of color or bias is applied. These subtle differences can also be exploited to disclose the existence of a possible exoplanet that has not been previously detected. During the first test image several targets were observed using different modes of SPHERE.

After performing more extensive tests and observations of scientific verification, SPHERE will be available to the astronomical community throughout 2014. ” . This is just the beginning SPHERE is a unique and powerful tool and will undoubtedly give us many interesting surprises in the coming years http “., Jean-Luc Beuzit

The first tweet of the CIA. Photo: File

A 14:49 pm today, the Central Intelligence Agency U.S. (CIA) first sent a message on the social network Twitter from a verified account and referred to simply as @ CIA

With characteristic secrecy published. “We can not confirm or deny that this is our first tweet”

<. p> Internet responded immediately. After two hours, the message was retweeted over 85,000 times and has added more than 125,000 followers.

“@ CIA what it feels to be followed for the first time?” answered a Twitter user.

But the CIA, which also joined Facebook on Friday, trying to illuminate its public face. “The extension of these platforms, the CIA will be able to participate more directly with the public and provide information on its mission, history, and other developments,” said the director of the CIA, John Brennan, in a statement.

“We have important information to share and we want to ensure that no classified information about the Agency more accessible to the American public that we serve, consistent with our national security mission.”

The Agency also undertook to publish “the latest and statements” of the CIA, along with museum artifacts, updates its World Factbook and intelligence rated.

With the official launch on Facebook and Twitter, the CIA is expanding its online presence limited beyond its public website and Flickr and YouTube accounts.

Compared to some rivals government agencies the CIA has to get to work. The National Security Agency joined Twitter in 2009, while the FBI did in 2008. .

Digital natives, the weakest link of linguistic correctness – La Vanguardia

Madrid, June 6 (Reuters) -. Digital natives, the generation that has been born in a networked and digital world, are the weakest link in the chain link linguistic correctness and risk, if the education system does not correct it, of oversimplifying language and therefore thought.

That’s one of the conclusions of the IX International Seminar on Language and Journalism, held last week and have released today its organizers, the Foundation of Urgent Spanish (Fundéu BBVA) and San Millan Foundation Cogolla.

The meeting, the Princess of Asturias inaugurated with an appeal to an essential element of rigor the practice of journalism, attended linguists, journalists and experts in social networks and computer processing of language, who discussed how the new digital media environment may be influencing the Spanish of today and how it will do in the future.

The conclusions of the seminar highlighted the coexistence in the field of digital texts written with linguistic quality criteria comparable to that of traditional media with other formats and governed by immediacy, often private or semi-private media, writings far from the standard way.

The tendency to write what is pronounced by removing or adding other letters (“aora Thin Man”), the removal of double letters (“Exar” to “take”) , removing punctuation marks (“you come from?”) or use as part of emoticons (“:-)”), are just a few features of this type of digital communication.

As the reduction words to their consonants (“dnd KDMS?”), expressive lengthening (“Koha”), abbreviations and the use of symbols and numbers (“tkm” “+ o-” or “sl2″) or the expressive use of capitals as shouting.

For the experts at San Millán some of them “are threatening” linguistic norms that achieve both cost-only since 1927 can speak of a real Spanish orthographic unit.

While these forms constitute a simple shift register, a form of expression that can be alternated with other more “formal”, is not serious, said the findings, which warn of the risk that digital natives learn only to manage these new codes, which would lead to a simplification of language and, therefore, “a reduction of critical thinking.”

It is therefore essential, added that the education system to ensure that these new generations, “in addition to these new records, can operate with ease in more formal.”

In the various committees held during the seminar was also addressed how the new digital environment affects the role of the journalist and his way of using language.

Absence in the digital environment context that facilitate traditional media and the many ways in which a reader can get to make news, for example, that “owners charged renewed importance. “

As with having to use a language recognizable by search engines, the need to constantly jump from one format to another.

The combination of formats traditional with new ones as the “minute by minute” and the debate on the contrast between short and longer content led to the conclusion that “the short genres have to give the counterpoint of a slower and thoughtful journalism” and the warning that “it is not that long journalism not interested; not interested in bad journalism. “

The conclusions of the seminar can be found on the website of Fundéu BBVA (www.fundeu.es) also mentioned that social networks” are the perfect field training in both journalism and other forms of narrative. “

Besides in journalism today,” unidirectionality is over “because it has created” a new communication experience “with a reader, more that is already “connected person”.

Digital natives, the weakest link in linguistic correctness – La Voz de Galicia

The expression ‘ digital natives “is entering the common language. Something comparable to how google verb turned. Already generations who were born surrounded by all kinds of mechanical and technological function in a way different from the rest. Share emotions, see information as something that can be distributed to all your contacts, and use instant messaging to make friends, find romance or look for a job.

But, this generation is the weakest link in the chain link linguistic correctness and risk, if the education system does not correct it, of oversimplifying language and therefore thought. This conclusion they have reached the IX International Seminar on Language and Journalism , held last week and have released today its organizers, Urgent Spanish Foundation (Fundéu BBVA) and San Millán Cogolla Foundation . The meeting, the Princess of Asturias inaugurated with an appeal to the rigor at the heart of the practice of journalism, attended linguists, journalists and experts in social networks and computer processing of language, who discussed how the new digital media environment can be influencing Spanish today and how it will be in a future.

These findings highlight the great existence in the field of digital formats governed by immediacy, written so very away from the Linguistic rules , and the problem this poses to the appropriate dissemination of the texts with linguistic quality comparable to traditional media.

trend writing what is pronounced by removing letters or adding other (“aora horn ‘), suppression of double letters (” Exar “to” take “), removing punctuation marks (” you come from? “) or use as part of emoticons (“:-)”), are just a few features of this type of digital communication.

well as reducing words to their consonants (“dnd KDMS? ‘) expressive lengthening (‘Koha’), abbreviations and the use of symbols and numbers (“tkm” “+ o-” or “sl2″) or the expressive use of capitals as shouting.

For experts gathered in San Millán some of them “are threatening” linguistic norms that achieve both cost-only since 1927 can speak of a real Spanish orthographic unit. While these forms constitute a simple shift register, a form of expression that can be alternated with other more “formal” will not be serious, said the findings, which warn of the risk that digital natives only learn to manage these new codes, would lead to a simplification of language and, therefore, “a reduction of critical thinking.”

It is therefore essential, added that the education system to ensure that these new generations, ‘In addition to these new records, can operate with ease in more formal. “

In the various committees held during the seminar was also addressed how the new digital environment affects the role of journalist and his way of using language.

Combining traditional with new formats like the “minute by minute” and the discussion of the contrast between short and longer culminated content the conclusion that “the short genres have to give the counterpoint of a slower and thoughtful journalism” and warning that “it is not that long journalism not interested; not interested in bad journalism. “

The conclusions of the seminar are available on the web Fundéu BBVA , is also mentioned that social networks” are the perfect training ground in both journalism and other forms of narrative ” . Besides in journalism today, “unidirectionality is over” because it has created “a new communication experience” with a reader, more than that, and a ‘connected person’.

The shock from another planet to Earth was the origin of the Moon – The Confidential

Most planetary geologists believe that the Moon was formed by a giant impact between Earth and a planet-sized object called Theia about 4,500 million years ago. To confirm this, scientists have focused in recent years in measuring different isotopes-atoms of the same element with different numbers of neutrons, such as titanium or silicon in lunar and terrestrial samples.

The isotopic ratios vary between objects in the solar system, but it turns out that in the case of the Earth and Moon are very similar, which conflicts with the theoretical models of the major collision. If this really happened, the moon would have formed from fragments of Theia, and therefore, one would expect that its composition was different from that of Earth.

Now we can be reasonably sure that the great collision took place, and we have an idea of ​​the geochemistry of Theia

Now a team of German researchers, coordinated by Dr. Daniel Herwartz University of Gottingen, has obtained measurements of oxygen isotopes expected to provide evidence that the moon originated by Theia collision with Earth. The work is published today in Science and is presented next week at the congress of geochemistry Goldschmidt (USA).
Team found that lunar samples analyzed with higher values ​​in the isotopic ratio of oxygen-17 and oxygen-16 relative to terrestrial rocks. Specifically, the difference is 12 parts per million (± 3 ppm)

“The differences are small and difficult to detect, but they are there,” says Herwartz, who plays this poses two developments.: “Now we can be reasonably sure that the great collision took place, and also gives us an idea of ​​the geochemistry of Theia, which looks like it was similar to the type chondrites E (a kind of meteorite enstatite).”

“If this is true, he adds, we can now predict the geochemical and isotopic composition of the moon, because the moon today is a mixture of early Earth and Theia. The next goal is to figure out how much material is missing planet in the Moon. “

How is Theia on the Moon

Most models estimate that the moon contains between 70% and 90% of material Theia, and the rest from ancient Earth. Nevertheless, some scientists believe that there is only about 8% of the Moon Theia. By Meanwhile, new study results suggest something in between: “A mixture of 50% seems possible, but needs to be confirmed,” said Herwartz

For the study, the team used its first lunar samples that had come to Earth via meteorites, but as they were contaminated for the exchange of isotopes to ground water, they decided to look more pure.

These the NASA provided from rocks collected during the Apollo 11 mission 12 and 16, and were then analyzed by a technique of mass spectrometry. With this same material although such isotopes such as titanium, but were not detected differences observed with oxygen.
