Sci RIVER tists succeed sequence the gene inheritance & eacute; tica 2,500 people – EntornoInteligente

Scientists manage to sequence the genetic heritage of 2,500 people / Emol / HEIDELBERG.- More than 200 genes of human heredity can be eliminated. This is just one of the many discoveries made by an international research team for the study of the genetic heritage of over 2,500 people on four continents.

“We were surprised to discover that more than 200 genes that some people do not exist at all,” said one of the study directors Jan Korbel, the European Molecular Biology Laboratory (EMBL) in Heidelberg, West Germany .

The data shows that there are still hitherto unknown which regions of mutations or heredity may play a role in the formation of disease.

The team of several hundred researchers presented the results of the “Genome Project 1000″ in two studies in the journal “Nature”.

The human genome consists of 3,000 million components, which among other things make up genes one by one. However, there is no genetic inheritance like another. 1000 Genome Project said in 2008 to 2,500 sequencing human genomes and to make a catalog of human genetic variation.

It is intended to help scientists and as a database in biomedical research to find the causes of diseases and possible starting points for therapies. Researchers are terminated the project with the publication of two studies. The sequence data are available on the Internet.

“The database is enormously important for the scientific community. We hope now the data to scientists, researchers, seeking the genetic basis of diseases,” said Korbel.

On the European side participated the EMBL in Heidelberg and researchers from the Max Planck Institute for Molecular Genetics in Berlin.

The researchers collected and analyzed the genomes of 26 populations as the Yoruba of Nigeria, Han China, the Tamils ​​of Sri Lanka, Peruvian and European subpopulations in the United Kingdom, Italy and Finland. Ethnicity

In 2012 published the first results after more than a thousand genomes sequenced. The two new studies not only have more genomes, but also include more details.

“Instagram is not just happiness and selfie sticks” – RPP News

Instagram is claimed as a documentation of human nature that has 400 million cameras, not only the fate of the happy photos and sticks to the ‘selfis’ he said its global responsible business and brand development, James Quarles.

“We have to be the place where people start their day, which will first get up. Because we are useful and because we offer things that matter (…) Instagram is not just the social network of happiness and Bats ‘selfi’ “Quarles said in an interview with EFE.

The Digital Photography , owned by Facebook, celebrates five years on 6 October with 400 million users, an increase that, according to the manager, answers that has been articulated as a platform for “genuine and creative” expression of both myself and what that happens in the world and a place to connect with others with which interests are shared.

“It’s not a chat room, or a place to be anonymous, but a space in which he said ‘that’s me and that’s what interests me,’ “he said.

” On our best days, we are the social network of happiness. But happiness is not the only emotion expressed: we have seen riots in the US, snowstorms, the refugee crisis … There harsh images and impacting not only happy and cheerful. We have 400 million cameras documenting what is happening in the world, “he stressed.

The immediacy and the community have been instrumental in the growth, he says, more than the pursuit of the perfect photo or filters . Also the injection of Facebook, which acquired Instagram in 2012 by 1,000 million dollars,:. “would have been impossible without Facebook,” he says

From this month, users the world will see ads on Instagram today and from advertising will be available for all types of advertisers, large and small.

“The advertising will become a natural part of the Instagram experience. We are very aware of the data to figure out the right amount of ads that do not interfere with the activity of users, to achieve balance. We always say that seeing ads in Instagram has to be like flipping through a magazine, “he says.

Quarles insists several times during the interview that the team continuously monitors statistics and response users ads to determine which proposals work.

“We want to prove that ads as relevant as the actual content of users. (…) We want to help companies find their voice and visual connect with our community, “stresses.

To do this, continues working with brands to launch interesting ads, try scoring serving advertisements to the right, with the same system Facebook- and attach importance to audiences tool with which users indicate they want to hide a particular ad or a brand.

At the moment, ruled Quarles Instagram go to become an e-commerce platform and argues that it is more conducive to the discovery of brands and products for purchase environment.

also appears in the horizon of the social network to launch a free version of the ad in exchange for a monthly subscription fee, as do services like Spotify.

“We want to grow our community more to limit such growth business model. The subscription does not make sense to us. Everyone will see ads in Instagram, will come naturally as it is on television or in magazines, “he says.

According to Quarles, the impact of advertising campaigns Instagram is 2.8 times higher than the conventional ads on the Internet.

The management changes that platform in the near future have to do with providing creative tools for users with improving the discovery of the images that may be relevant to them and with direct and private communication between users.

And the virtual reality that has been dabbling with Facebook Occulus Rift? “There will be some experimentation with spherical photos that you see more than 180 degrees. (…) We love to innovate, but I’m not sure how we could include virtual reality from the point of view of both production and consumption. “

Tesla Model X: a nod to the real DeLorean car to Back to the Future – Hypertext

Now is the predicted Tesla Model X , the new model of the company with a price of $ 130,000. Aesthetically seems a nod to all Back to the Future with its doors Hawk, formerly known as gullwing views Ferrari and Lamborghini models mainly. These doors detect our presence close to open, it is not necessary even to touch or manually activate a remote control. And if we close the doors to open barriers, as parked cars too close, the Model X detects and opens differently, more vertically to avoid hitting them. They also have sensors to not bump into the roof of a garage, for example.

One of his key points was autonomy that reaches 402 kilometers as Tesla. Its acceleration is 3.8 seconds to go from 0 to 100 kilometers per hour and a maximum speed of 240 kilometers per hour. And above all, it stresses the car seven seats , distributed in two rows in front, three in the middle and one behind. And speaking of “behind” the Model X has a load capacity of 2,200 kilos of trailer, something that seemed impossible in an electric car.

The Model X also includes a system of cameras and sensors to security. For example, “rectified” the driver if he goes out of the road. However, it can be cataloged, much less as an autonomous vehicle, and a priori 7.0 update itself and get what was coming this year, still have to wait. Also it is taken into account driving in polluted areas: the electric motor has three particulate filters to keep it clean even if we live or routinely drive by directly anti-ecological zones. These filters, ten times larger than traditional, also retain up to 800 times. We have also shown a button that literally seals the car’s exterior, which could even withstand us … inside a biological attack. It seemed a joke, but no.

In the coming weeks the first Tesla Model X will be coming to California’s roads, where the company is headquartered and vegetables are produced. However, it arrives with some delay compared to the initial plans, which placed him in February. During the presentation was expected to Elon Musk ruling on the Volkswagen case but did not.

Even still needed to see if the prophecy of Musk is true and we see over the next few years they come in so massive electric cars to “low” prices, estimated at around $ 35,000 for the first stage of overcrowding. Tesla plans to produce 500,000 pass cars a year by 2020.

NASA’s dilemma: how to investigate the water found on Mars without contaminating the Red Planet in the process – BBC

It was a historic announcement.

This week NASA confirmed that, after years of speculation, found the strongest evidence of the presence of liquid water on the surface of Mars.

Those long, dark lines observed in some regions of the world are due to salt water flows downhill slide craters and outstanding during the summer months, experts

Read:. Why is it so important that there is flowing water on Mars

The news immediately led to the big question: if water Is it possible then to find microbial life on Mars?

The best way to answer this question is obviously looking for her.

But before this perspective, the US space agency faces a dilemma. How to do it without polluting the planet in the process

Wrong category

In theory NASA You may order now at The robot Curiosity that is investigating the field-you approach one of the four areas where hydrated salts have been detected in recent days.

The problem is that the robot is not sterile and can contaminate the area with terrestrial microbes that inadvertently joined the trip and can get to be alive.

The vehicle is taking samples and looking for evidence of whether Mars was habitable in the past since arriving at Mars in August 2012.

Now could approach to find places to take a closer look and use their instruments to analyze soil composition

But there is an organization, the Committee on Space Research (COSPAR, for its acronym in English) that property has and a set of rules to prevent human pollute the pristine worlds without explore.

According to this entity, robots landing in this case, amarticen- on a celestial body other than the Earth on a mission to search for life must be exceptionally clean.

These are described as IVb category vehicles.

But for those who enter special areas, as would be the case now discovered on Mars by NASA areas, the rules are still more stringent.

Such vehicles, like Curiosity, fall into the category IVc.

And, as established Cospar, you can not come.

2018

In the coming months discussions will focus on what you can or can not do the Curiosity and how far they may approach.

However, beyond the regulations, the debate extends to what the real possibilities of contamination.

Some experts believe that the risk is minimal and that even if there is contamination, genetic analysis can show how life forms belong to a planet and what the other.

Others like Jim Green, NASA expert, say the intense radiation of Mars, especially ultraviolet light, is enough to kill any stowaway Earth.

While for National Academy of Sciences and the Foundation for Science happen quite the opposite. consider that the ultraviolet light would prosper

The ‘big’ and the new video game from tomorrow in Madrid Games Week – Yahoo Finance Spain

Madrid, Sep 30 (EFE) .- great sagas of video games and independent proposals of the Spanish studies of interactive entertainment come together tomorrow in the third edition of the Madrid fair Games Week to be held in the Ifema until Sunday.

The fair will devote 30,000 square meters to teach the new world of interactive entertainment, recent proposals of Spanish studies and host game e-sports tournaments.

One of the main attractions of the show is the power play titles that have not yet reached the market, which include “Call of Duty Black Ops III”, “Dark Souls 3 “,” The Legend of Zelda: Tri Force Heroes “,” Assassin’s Creed Syndicate, “” Star Fox Zero “,” Uncharted 4: The outcome of the Thief “,” Street Fighter V “Dragon Ball Z: Extreme Butoden”.

Also experiences with virtual reality headset Sony.

There will be a total of 150 exhibitors and more jobs in the game last year, but this year will have a significant absence MGW because Microsoft will not display their latest there.

Games Week Madrid attended by a total of 70 Spanish gaming companies. Spanish developers show titles for virtual reality glasses, smart watches, tablet, or mobile computers.

In addition to meeting the Spanish developers Gamelab Academy has organized various lectures to guide those who wish engage in the business of video games.

Google Pixel C – Faqs Android (blog)

Google has done what many did not expect, provide a tablet with a similar concept that we saw in the Microsoft Surface or the new iPad Pro but with Android 6.0 Marshmallow. you read correctly, no Chrome OS. Pure and hard for a terminal with a keyboard coupled with 10.2 inches, will be named Google Android Pixel C.

There is a laptop to use it a convertible tablet for your keyboard will disengage and the operating system will remain Android, Anyone who sought a piece of this kind but did not dare to take a Chrome which option system, Chrome OS still has a long way show . The body, full metal, has a 10.2-inch screen with resolution of 2560 × 1800 gives us a density of 300 pixels per inch, good enough for a device of this kind. As main handicap itself will have it is that we have said here many times poor ecosystem productivity applications for existing tablets on Google Play. We hope that the arrival of this Pixel C means that Google will pay special attention to a tablet to take the experience of a portable light work.

For now we will have only in the US and not be cheap. We talk about $ 750 for the top model , which contain 64GB of internal storage and will with its attachable keyboard with magnetic Close. We hope that Google are encouraged to bring it to Europe for this concept, the convertible tablet, was already a reality in several manufacturers. Even the Nexus 9 incorporated a keyboard, do not forget

Features

This Google Pixel C, with keyboard, but it is not essential and can buy it without him, comes with an all metal body like the one we saw in another product of Pixel family, Chromebook Pixel. His screen with 4: 3, has a diagonal of 10.2 inches , 500 nits of brightness and a resolution of 2560 × 1800, which leaves a density of 307 pixels per screen inch. The chosen processor is manufactured by NVIDIA, we speak of a Tegra X1 , an ARM chip with quad-core 64-bit and enjoying a GPU Maxwell.

In terms of memories, Google will Pixel C 3GB RAM LPDDR4 , the fastest mobile memory market right now, and Two storage options: 32 and 64GB that can not be expanded with microSD but with an external USB drive thanks to its USB host port, besides being USB type C . In we find WiFi connectivity and we know nothing yet about a possible model with LTE in the future, although it would appear logical that one. Battery, unspecified promises two days and use Marshmallow come with Android 6.0 . The keyboard with magnetic closure, not be binding but can be purchased separately with a choice.

Snail are passing through the eye of a needle – The Nacional.com

He was found in southern China and believe it could be the smallest land snail world

The National Web September 29, 2015 – 8:42 pm

The world’s smallest snail was discovered in the province of Guangxi in southern China and placed the name of Angustopila Dominikae .

Although it can be seen without a microscope, this snail is about 0.86 millimeters. It is the smallest seven tiny species found in soil samples collected by a Hungarian traveler at the foot of a limestone hill.

Compared to its larger relative, the African snail, is nine million times smaller.

Also because they have a fingerprint reader to access the phone safely. Both devices come with the new version of Android: 6 or Marshmallow
The differences go through the design and materials;. and the front camera (for selfies) against 5MP 8MP between the two models. The 5X model will be manufactured by LG, following the trend of previous versions were also made by the South Korean company; while the 6P is in charge of China’s Huawei.

If Apple had pulled chest with his new iPad Pro (super widescreen 12.9 “and stylus), Google answered with the new Pixel C, its first high-end tablet based on Android system and made by the same Google. It stands out for its “convertible” Bluetooth keyboard. It has screen 10.2 “Android 6 4-core processor, USB ports and a very elegant line.

The presentation was chaired first by Sundar Pichai, Google’s new CEO. The company also introduced new versions of its Chromecast device that connects to the TV and can see there that you have content for mobile devices. The new pass design (now round and multi-colored); and also by the new version Chromecast Audio to listen to music on any stereo. Similar, but different from Apple TV.

Predominant inbreeding among Neanderthals The Sidrón – lagranepoca

First cervical vertebra, called the atlas, where the congenital anomaly were observed. / Communication CSIC

The Neanderthals lived in small groups, isolated and relatively low genetic diversity, according to a new analysis of skeletal remains found in the cave of El Sidrón (Asturias ). The work, led by the Higher Council for Scientific Research (CSIC) and published in the journal PLoS ONE points to the high incidence of birth defects in the first cervical vertebra , called Atlas, along with the retention of canine teeth, may be the result of inbreeding in the group of Neanderthals who lived in that cave.

“Congenital anomalies have been found in two of the three atlas recovered at the site of The Sidrón, a group consisting of a total of 13 Neanderthals, “says Antonio Rosas, director of the study and researcher at the CSIC at the National Museum of Natural Sciences (MNCN).

According to the researcher,” the atlas bone forms a ring which rests the skull, and can have a variety of congenital anomalies of low frequency in the front and back of the ring. ” Among these abnormalities, “the simplest is dehiscence (lack of closure) of the posterior arch in the median line, which current human populations occurs with low frequency, ranging from 1% to 4%,” explains Rosas.

“In clinical practice, the discovery of this defect Atlas is casual in most cases, and is often caused by medical imaging tests (X-rays, CT axial) requested by example by trauma to the cervical region, “says Luis Rios, first author of the paper and scientist MNCN.

” One of the atlas of the Sidrón presents this defect. The second atlas presents a dehiscence of the anterior arch also in the median line. This is a defect that occurs much less frequently, below the 0.1% in modern human populations, “says the researcher.

Three possible explanations

How the presence of two of these congenital anomalies of low frequency in a Neanderthal as small group explained? “There are three possible explanations,” says Antonio Rosas. The first is that this congenital abnormality has a genetic basis and the high frequency indicates that these two individuals are familiar Neanderthals. This interpretation marries genetic studies in the Sidrón, where family relationships between individuals in the group are deducted.

The second explanation It is superimposed on the first, and aims to inbreeding or “practice of marrying persons of common or natural heritage of a small town or region”, as defined by the SAR. Indeed, the demographic scenario drawn to Pleistocene human groups is small and scattered, which would favor the pairing within the group and consequently, long-term, within the same family.

“Over time, inbreeding can lead to an increase in the frequency of small variations and congenital skeletal abnormalities (as transposed teeth, spinal defects such as dehiscence of the atlas, cervical ribs) and a higher frequency of these anomalies has been observed for example in island or human populations located in isolated areas, “explains Rios. Even in conservation biology these anomalies can be used as indicators of inbreeding in areas of repopulation of wildlife.

On the other hand, recent genetic studies on samples from El Sidrón, Vindija (Croatia) and Siberia (Russia), would point to a common match between Neanderthals with close kinship relations, and congenital anomalies of the atlas in the Sidrón could be interpreted as another sign, in this case skeleton, inbreeding Neanderthals in this geographical area.

Together, “the demographic picture of Neanderthals groups clarified in recent years can give a biological explanation for the numerical decline of their populations, which over time could have led to its final extinction, “said Rosas.

A third explanation linking possible congenital deficiencies (eg, defects in neural tube closure ) with adverse environmental conditions during the early periods of gestation, such as a power pattern deficient in some nutrients. Although the accumulation of genetic data and osteological signals a demographic scenario of inbreeding, the testing of this hypothesis will only further studies of Neanderthal remains, the researchers conclude.

Why is it so important that there is flowing water on Mars – La Nacion (Argentina)

NASA researchers have confirmed in the last traces of water ice on Mars; however, the recent announcement about the possibility of liquid water is called revolutionary

NASA called the finding exciting development.

Following the presentation on Monday of the latest findings of the US space agency, NASA, in relation to the presence of currents Water on Mars were many who made the partnership with the possibility of life on Mars.

For years it has been known that in the past there were large quantities of water on Mars and It is known of the existence of frozen water beneath its surface.

The importance of this latest discovery, tells BBC World Mary Beth Wilhelm, a researcher at Arnes Center of NASA in Moffett Field, California, is that “It is the first time that there is direct evidence of the existence of liquid water on the surface of Mars.”

Wilhelm adds that he does not yet know where the water comes, but indicates that it is likely that It is the atmosphere.

Earlier this year, NASA reported that almost half of the northern hemisphere of Mars was once an ocean, with a greater depth of 1.6km.

Another new aspect of Monday’s announcement that it is possible that the flow of salt water are given today, not something of the past.

Is there life on Mars?

With very few exceptions, water is necessary for life as we know it.

However, the researchers call for caution. The fact that there is water ice, current, or both, do not directly imply that there is life on Mars.

The NASA researchers rated Monday as recent findings.

“It is very difficult to determine the answer to that question,” says Mary Beth Wilhelm.

“The first step to find out whether or there was life on Mars it is to determine what living is the environment, how extreme are the conditions on the planet.

“Running water is an essential ingredient for life, is a requirement for habitability. The presence of liquid water is a step to establish that the surface of Mars is a place that can be inhabited, “says NASA expert.

The dark veins that appear on some slopes of Mars can be hundreds of meters long.

” is not the planet Mars dry and arid we thought in the past, “said Jim Green, director of NASA’s planetary science.

Meanwhile, Joe Michalski, researcher Mars Natural History Museum in the UK, it says the announcement is an exciting development, especially for what it means in terms of the possibility of living microbes on the planet.

“By studying extremophiles in -microorganismos Earth living in conditions extremas- know that some living beings not only survive but thrive in very dry conditions, highly saline or any extreme case compared to what is habitable for a human being.

“In fact, on Earth, wherever we find water, we find life. So the discovery of water on Mars for the past 20 years is so exciting, “he says.

Future studies

Mary Beth Wilhelm, NASA insists that these are first steps that require much more research.

“We have a robot on the planet (Curiosity) and send another in 2020 for signs of life,” he says, in addition to continuing the research that develops from laboratories on land.

“We still have to determine how much water there and its origin is still a mystery. Those will be our next steps, “he adds.

The red planet called awake fascination among researchers and the general public.

There is also talk of the possibility of sending a manned mission to Mars.

“It’s something we’re working on, is one of the objectives. We hope that our current discovery makes it more possible. Finding water on the Martian surface that will make it easier to survive on the planet and will make it cheap. “

Sterilize the probes

An interesting consequence of the recent findings is that space agencies will have to think carefully where they send their future probes and robots.

The internationally accepted standards stipulate that the missions have to be cautious when going places on Mars where it may have liquid water .

“Under certain circumstances, tap water found on Mars,” said Jim Green, NASA.

Peter Grindrod, expert from the space agency in the UK, told the BBC:

“The planetary protection states that we can not go anywhere where there is liquid water because we can not sterilize ships well enough to ensure that these places do not pollute.

“So if is a landmark in the landing of a probe, you simply can not touch down there.”

 The discovery of water on Mars announced Monday by NASA encourages the hope of life and provide a precious resource for human exploration of the planet.
 
 They found water on Mars and find life expectancy grows
 

“We now have the possibility of going to the right places on Mars to eventually find life”, estimated John Grunsfeld, deputy administrator of the US space agency NASA.

“I think this will spur our engineers and scientists to invent instruments capable of detecting life, “added exastronauta.

” We have the ability to go to Mars to study these issues and answer life. This is no longer an abstract issue but good concrete, “he said as Jim Green, director of planetary science at NASA.

The scientists explained that the possibility of microbial life on Mars is” very large “and there are probably layer groundwater.

“For me, the likelihood of microbial life below the surface of Mars is very high,” judged Alfred McEwen, a researcher at the University of Arizona, principal responsible Imaging System (HiRISE) aboard US spacecraft that made this finding.

This life can probably only exist underground because the surface of Mars is inhospitable, mainly by ultraviolet radiation from the sun that would destroy any life that as we know, the astronomers explained, pointing to the low density of the Martian atmosphere, consisting of 95% carbon dioxide (CO2), which offers no protection.

Michael Myer, Chief Scientific Program Mars exploration at NASA, said for his part that is ignored where the responsibility for these stelae that appear on steep slopes in some places the red planet during the less cold seasons, before disappearing water comes at low temperature . This phenomenon was first observed in 2011

-. Growing plants –

The water could be found in the basement, and it does not rain on Mars, he said. And it is “imperative” to find other more affordable places in the world where the same phenomenon is occurring and find the sources of underground fresh water.

“We suspect that these places exist only because we have some scientific evidence to make us think that

“said John Grunsfeld, adding that” this will be a fascinating exploration path in the future. “If there is enough water on Mars then it will be possible to grow plants indoors inflatable greenhouses, predicted scientific. As plants convert carbon dioxide (CO2), abundant on Mars, oxygen, this could be a useful mechanism for future explorers, allowing both produce food and achieve a breathable atmosphere, he said.

The NASA managers are confident in the capabilities of the next explorations, planned over the next five years to discover more secrets of the red planet. This would advance the future human exploration programs.

The NASA launched in March 2016 and a new robot, named InSight, which first makes exploring the bowels of Mars through a piercing radar. This instrument “might discover aquifers, which would be a huge step forward” to prepare the necessary resources for future explorers, Grunsfeld said.

The European Space Agency (ESA) as part of its ExoMars program, in 2016 it plans to launch a satellite that will orbit around Mars, which will continue in 2018, in a program with Russia, a robot and a scanning platform in the planet’s surface. The aim is to detect methane and other signs of biological activity.

Finally, in 2020, the United States will send a new exploration robot Curiosity similar to but more sophisticated, with the goal of taking soil samples Mars and return to Earth.

The US space agency plans to send the first mission to Mars not inhabited before 2030.

Water on Mars facilitate human visitation – The Nacional.com

detected Dark streaks on the slopes of craters on Mars are so far the strongest evidence that liquid water exists today intermittently flowing on Mars.

The suspicion has always existed. Not only because some 4,500 million years ago the ocean covered 19% of that planet, but by the same desire of mankind to be so.

Yesterday, NASA released the results of an investigation that raises that striations on hills and canyons of Martian soil, which seem the paths of rivers on Earth are the result of a seasonal cycle of liquid water.

“When most people talk about water Mars, generally refers to water or freezing old. Now we know there is more to this story. This is the first spectral detection unequivocally supports our hypothesis formation of liquid water, “said Lujendra Ojha, the Georgia Institute of Technology in Atlanta and author of a report on these findings published in the journal Nature Geoscience.

Ojha first saw those mysterious lines obscuring the Martian slopes five years ago, so the new findings, he says, are water today. His work was based on images taken by the Mars Reconnaissance Orbiter (MRO), a probe that has examined Mars since 2006 with six instruments.

“The instrument made the discovery in infrared. It is that what we are looking at is the infrared light that comes on the Martian canyons and slopes and bouncing to give us information about the material and the chemical composition thereof. What is missing is now confirmed, it is not enough to have detected those signals in a studio, “explains Santiago Vargas, research professor at the Astronomical Observatory of the National University.

David Tovar, co-director of the Planetary Science Titan and astrobiology, National University, says the support of research is found that the flows are the product of a sequence of pictures at different times of the Martian year, where temperature variations caused changes in the physical state water. So it will go from solid to liquid.

But there is water like rivers on our planet. Vargas says that was detected on Mars is -23 degrees Celsius, five times colder than the fridge freezer. “So water can flow at that temperature, because it is below freezing (which is 0 degrees), salts fall that point are required,” he says.

Tovar explained that these salts are known as perchlorates, which are highly polluting chemicals -make the water unfit for consumption-and abundant on Mars, which effectively lower the freezing point. It is similar to what causes salt to be put on the snow in winter time to avoid the streets are covered in this effect.

Possibility of life?

While the desire to search for liquid water outside our planet is directly related to the possibility of life, this finding does not ensure that it exists on Mars. “We are not finding life is a first step to encourage us to continue to explore what causes this water, where else is there, then do deeper to focus on the chances of finding microbial life that can survive in the aqueous environment studies,” he added Vargas.

But neither is discarded. Jorge Bueno, director of the Astrobiology Institute of Colombia, said that this discovery would Mars as a potentially habitable planet. “In terms of chemistry, adaptive process that the ‘bodies’ have is corroborated. And from astrobiology, I would say that if it is very salty water could think of halophilic organisms living in environments with high salt, “says the expert.

To Tovar, research gives evidence that on Mars there possibly microbial life. “But this is not a biomarker. For this, a testament to an organization with active or that it has had in the past metabolism is needed, “he insists.

The future space missions designed around 2030 to put a man on Mars would benefit from confirmed this thesis. Vargas said that would solve one of the problems that long mission, which is to supply liquid to the crew.

The world celebrates this development, because, as said Michael Meyer, chief scientist of the Exploration Program NASA Mars, “this mystery involved sending multiple spacecraft for several years. We now know that there is liquid water on the surface of this cold desert planet. “

Apple had record sales of the new iPhone – El Diario de Yucatan

         

     

SAN FRANCISCO (EFE) .- Apple said yesterday it sold more than 13 million new iPhone models during the first weekend it was available in twelve countries, which set a new record for the flagship product of the company California.

“The iPhone sales iPhone 6s and 6s Plus have been phenomenal, exceeding sales of any other first weekend in Apple’s history,” the CEO said yesterday in a statement the company, Tim Cook.

Analysts predicted sales would range between 12 million and 13 million, what Apple exceeded expectations.

Apple sold more than 700 million mobile devices since their debut in 2007, although its market share of 16%, is well below the 81% who have phones equipped with the Android operating system from Google.

The iPhone went on sale last Friday in twelve countries, including the United States, France, Germany, Canada, Japan and a group of nations where none appears speaks Spanish and Brazil.

Apple said the iPhone 6 and 6s iPhone will be available in 40 more countries from October 9, including Mexico, Italy and Russia.

The new phone will be available in more than 130 countries at the end of the year.

The iPhone is Apple’s most profitable product, accounting for about 56% of its profits.

The new models, which Apple promotes itself as “the most advanced smartphones in the world”, incorporating cameras of 12 and 5 megapixel rear and front, respectively.

Minivídeos

The new rear camera has the ability to record in ultra-high definition 4K or minivídeos created with each picture, so so that pressing the image reproduces briefly the moment when the photo was taken.

The devices also include the new 3-D Touch feature, which lets you create a menu control function pressure exerted on the screen, which will be more resistant.

The new iPhone uses the same processor as the iPad Pro, A9X, which has an output 70% higher than the current iPhone in June.

The release of the devices was marked by long lines at Apple stores in the countries where it was put on sale.

Despite this, the company fell Wall Street yesterday at 1.25%, which occurred regardless of record sales announcement of its new device

NASA announces the existence of liquid water on Mars – VAVEL.com

Thanks to the billions invested by NASA in the search for life on Mars, scientists have never doubted that Mars had harbored water millions of years ago had discoursed for those channels that legendary Italian Giovanni Schiaparelli discovered, and in 1908 by the astronomer Percival Lowell believed that liquid water flowed, but recent findings open an entirely new scenario that may forever change the history of space exploration and the search of extraterrestrial life.

The story of a passionate quest

Mars has always had a very high power of fascination in humans, and its exploration has been a goal and a dream that begins to bear fruit. From the Mariner program has been looking, they have invested many millions; many scientists have devoted their entire lives to reach such an exciting moment as I lived on 28 September 2015. Nine Mariner missions in which even got to participate Carl Sagan, who would be living with passion the new findings confirm the already established suspicion of science. The exhaustive exploration of Mars by NASA, has led to extraordinary discoveries. The Viking program replaced the Mariner and this was followed by the Mars Global Surveyor, which became the first success of NASA’s Mars exploration in two decades, after the failure of the Mars Observer orbiter. With the landing on Mars July 4, 1997 Mars Pathfinder , he took another very important step in the physical exploration of the red planet. NASA missions Express Odyssey and continued the arduous process of search and exploration of water and life on Mars. Spirit and Opportunity, joined NASA successes, burying forever injured early exploration of Mars. The working rovers on Mars in search of the liquid element, the first prerequisite for confirmation of life on our neighboring planet. Thanks to them, today the existing information about the chemical and mineralogical composition of Martian rocks and soil, is absolutely unquestionable. Their findings came to provide substantial evidence of water in the past. Stressing so very special rover Curiosity, launched within the NASA mission called Mars Science Laboratory.

LRN Mysterious Lines Recurring Slope

But absolutely decisive in the last findings has been the mission Mars Reconnaissance Orbiter , which had as its main objective to carry out reconnaissance and exploration of Mars from orbit the planet. The high resolution camera HiRISE carrying, has enabled the Martian terrain images are achieved with extraordinary clarity and definition. Precisely this chamber the Mars Reconnaissance Orbiter (MRO), was crucial for observing a phenomenon that iced the Nepalese student at the University of Arizona Lujendra Ojha , who worked with the researcher Alfred McEwen . Ojha detected some unusual structures, some dark spots or streaks on some slopes of the Martian surface, which appeared in the warmer seasons and disappeared into the cooler. Call Lines Recurring Slope , Science magazine even published that could be due to seasonal streams of liquid water with a high concentration of salt.

liquid water with high salinization, why could eventually be liquid, since the salts lower the freezing point. Some salts called perchlorates discovered by the Phoenix in 2008 that would allow water on Mars was kept in a liquid state in a band between -70 and 24 degrees Celsius. The scientific community was already aware of the existence of water ice at the poles, but the press conference by NASA in Washington DC, has marked a before and after in the history of the search for life outside our planet. As one of the essential requirements for life could become so common that is very present in one of the planets of our nearest space area.

Historical press conference

NASA He made the big step photographic evidence showing that allowed corroborate the study; the US space agency made official, so far the most important announcement in its history. On Mars there is only water in the solid state, frozen, but liquid runs through the canyons and walls of Mars during the summer months. The news also published in the journal ‘Nature Geosciences’ partly funded by NASA, could be the final push and prior to confirmation of the scientific hypothesis that there is life on Mars step. Still ahead it is a long period of research, as scientists have not identified the source of the liquid element, shuffling three possibilities, being able to try to saline aquifers, underground ice or condensation may thin Martian atmosphere. But what is evident, just as stated has Michael Meyer, director of the Mars exploration program . “Because of this, we suspect that there is at least a possibility of a habitable environment on Mars today.”

So it was so intense, so exciting the press conference by NASA the first words of John Greensfield : “We explore space because we try to answer basic questions: Where did we come from? Where we go? We’re alone? In this case, we are investigating this because we go to Mars. ” The subsequent intervention of Jim Green, director of the Program of Planetary Science at NASA, stressed the importance of finding pointing to the rovers had found that there was more moisture they thought of Mars, and it was not that dry planet that scientific community believed. Because under certain circumstances, there is liquid water on Mars. Both Lujendra Ojha as Alfred McEwen, principal investigator for the experiment HiRISE, stated that it is too early to know what implications will this finding to search for life on Mars, but with the direct evidence of liquid water on Mars, the probability that there is life ( shaped microbes) on Mars is very high. And so the confirmation that the miracle of life is much more common than thought humanity is much closer to corroborate this historic scientific breakthrough.

Carl Sagan, somewhere something incredible waiting to be discovered

As Carl Sagan said in the message that he wanted to write down to future Mars explorers: “Science and science fiction have done a kind of dance over the last century, especially as Regarding Mars. Scientists make a discovery. This inspires science fiction writers to write about it, and a lot of young people read science fiction and be excited and inspired to become scientists to discover more about Mars, and they do, fueling another generation again science fiction and science. “

Surely the vast majority of scientists who dreamed to be, to be able to make great discoveries in the universe, the solar system and our beloved Mars, came the spirit Sagan, who wisely stated that site somewhere something incredible is waiting to be discovered . And if we’re alone in the universe, sure it would be a terrible waste of space, as the temporary absence of evidence is not evidence of absence.
