Facebook will include the button ‘I do not like’

Founder and CEO of Facebook, Mark Zuckerberg, said today that the network is developing an option that allows users to express their emotions beyond the option to “like”.

Zuckerberg made the announcement during a session of questions and answers from the company headquarters in Menlo Park (California, USA).

Facebook has resisted creating a button “I do not like” to accompany the popular “Like” for fear of generating discontent in the social network.

However, Zuckerberg has been open to create new options to the demands of users who argue that the “like” can not be used in all situations.

“It is important to give people more options than ‘I like’ to help them express empathy “, said Zuckerberg, who acknowledged that” not all times are good times “.

Zuckerberg said that the launch will be soon but considered unlikely that the option name is “do not like”.

A protein capable of regenerating heart cells after a heart attack

A team from the School of Medicine at Stanford University (USA) has found a protein capable of inducing the regeneration of heart cells after a heart attack in mammals, according to a study published in Nature.

The Spanish group led by Pilar Ruiz-Lozano has investigated the role of protein in the heart FSTL1 system of mice and pigs, whose heart, like that of other mammals, has limited ability to repair itself after a substantial loss of cells muscle (cardiomyocytes).

Scientists have identified that protein often found in the lining of the walls of a healthy heart (epicardium), but disappears in that area after a heart attack.

This situation can be reversed, however, applying a patch that simulates tissue epicardium and acts as a source of FSTL1 protein, which is achieved trigger proliferation of cardiomyocytes and cardiac function is improved.

“My team has patented a technology that we hope to market clinical applications” of this discovery, said the study’s lead author.

The future human therapy to counteract the effects of a heart attack would be to install a patch by surgery after a heart attack.

45% of heart muscle cells are renewed throughout the life of a human being, while 55% remain unchanged from birth.

That regeneration rate is not enough to repair the damage caused by a heart attack, so, after suffering the trauma, the body covers the affected area of ​​heart tissue fibroblasts, cells with little ability to contract to the Long compromise the organ’s ability to pump blood.

So far, the bulk of the investigation to a regenerative therapy has focused on the use of immature muscle cells derived from stem cells.

The Ruiz-Lozano group opted instead to investigate the characteristics of the FSTL1 protein, which previous studies had already revealed as a precursor to the development of various organs.

This protein plays a role in a wide range of diseases, such as arthritis, pulmonary fibrosis and cancer, due to their ability to activate cellular communication mechanisms.

Depending on which organ is, the protein is able to cause inflammatory responses, act as a factor of protection or induce cellular immune responses.

Israel, a technological barn booming

Israel, a technological barn booming

Beyond the conflict or of religious and tourist appeal of the Holy Land, Israel is home to a whole barn emerging companies have made very little time in a technological power, a figure that exceeds the thousand and seeks to expand its model success abroad.

The list is very long: cancer prevention systems in forest areas with mobile phones, to transform text on video and increase traffic to the “web” pages of the media, to cook healthy meals in a minute, to enhance interactivity TV viewers.

Also, to measure human clearly identifying pain in the brain, to ensure safety in automated driverless cars circulates, to recycle carbon dioxide from the atmosphere, to help the blind to read, to grow in the desert.

Innovative is huge explosion in this small, arid and unique country in the Middle East embroiled in a long conflict with the Palestinians. In fact, large foreign companies, without going any further the Spanish Telefonica, have decided to establish research centers to follow “in situ” leading-edge initiatives from the early stages of life.

“Large companies have realized that it is more cost effective to purchase a start-up while still begins its journey because that costs less , “said Efe department director for Central America Foreign Ministry of Israel, Lior Haiat Affairs.

So it sits on Israel, “to discover without waiting until the commercial phase of a product or service, what is cooking and what are the most promising developments”.

Almost a thousand “start up”

Only in Tel Aviv, the city that concentrates business, the number of startups or “start up” that exists around a thousand, what represent an average of 19 per square kilometer, the highest rate per capita in the world, even above the US . This figure would add that of other companies in other parts of the country.

It is small technology companies begin their journey with little resources, often among, usually young friends, with a few computers working from their own homes, and try to implement highly innovative projects.

Many fail, but that thrive tend to attract investors who bet on them to continue to grow, or directly end up being absorbed by already established companies.

Some 5,000 such companies are created every year in Israel, a figure that exceeds that of the entire European Union.

Of which approximately 80 percent fails although the rate is much lower than in the rest of the world ; they go ahead and get benefit, they also contribute to job creation, economic growth and social welfare.

WSCI 2015

Just this week in the prestigious Hebrew University of Jerusalem, whose founders is the genius Albert Einstein, being held through Thursday, the world of science macro conference WSCI 2015, with fifteen Nobel laureates and dozens of eminent international researchers and four young “talents” of universities in seventy countries.

One of the issues discussed was the consideration of Israel as a whole as a “start up” and there have been some recent innovative initiatives.

Acceptance of failure as an opportunity to resume a failed business, enthusiasm, good planning, clear organization of ideas and hard work are some of the keys to success, they have insisted the participants.

Other requirements for entrepreneurial success are favorable to the creation of companies that do not punish failure, entrepreneurial support programs, government support for the need to close your business and a close interconnection with the university legislative framework.

For the Israelis, also it influences passing for three years by the Army and experience from very young in difficult situations of conflict and the limitations to cross adjacent borders that seclude its small territory, as stressed in the conference.

Premature deaths will double in 2050 by pollution

Premature death from air pollution could double by 2050 and because the death of 6.6 million people each year, suggests a study published today in the journal Nature.

Jos Lelieveld, researcher at the Max Planck Institute for Chemistry (Germany), and his team have estimated the contribution of different sources of air pollution to premature mortality, combining a global model of atmospheric chemistry data on population and health statistics.

It is well known that air pollutants such as ozone and fine particles of less than 0.0025 mm, are associated with serious diseases.

The difficulty in measuring the incidence becomes a problem, on one hand, because the air quality is not monitored in certain regions and, secondly, because the toxicity of the particles varies depending on their origin.

The scientists found that this investigation emissions in urban areas , such as those from heating systems and kitchens, are having a greater impact on mortality worldwide premature.

The researchers emphasize that air quality in the United States and Europe has improved dramatically in recent decades thanks to legislation to improve the environment, a breakthrough that has had a positive impact on public health.

However, the study warns that in Europe, some regions of the United States, Russia and East Asia, the emissions produced by agriculture provide most of the particles that pollute the air.

Lelieveld and his colleagues argue that emissions from ammonia and other farm fertilizers are the second largest cause of mortality overall air pollution.

In much of the United States further particles from traffic and power generation plants they are of particular concern, according to the researchers.

In a study on mortality from air pollution published today by the journal Nature Geoscience, the researchers argue that reducing fires in the Brazilian Amazon has been averted between 400 and 1,700 premature deaths a year.

Dominick Spracklen and his group have used satellite images and field measurements to conclude that the concentration of suspended particles in the air has declined by 30% during the dry season in the region.

Interview: Kevin Ho, president of the mobile devices division of Huawei

The key to success lies in the basics: calling and surfing the internet with fluency and quality”

Kevin Ho

Kevin Ho is specialized in design engineer and has worked many years in the R & D of the third mobile phone maker in the world, Huawei, which now manages all product strategy and research to enlighten a new generation of mobile devices very different from the current, well kept secret in the headquarters of the company.

Ho was involved in the recent edition of the fair IFA in Berlin where I had the opportunity to introduce new phones in the Chinese firm, including its current flagship product, the Huawei Mate S, an advanced model that they want to change the touch experience and form we interact with the device. What are they trying to achieve with this new terminal?

“In our Mate S we have opted for the power of touch. One of its main features is the fingerprint sensor 2.0, the second generation of this technology increases the effectiveness and speed to unlock the phone. Secondly it highlights the activity and the third knuckle Force Touch to measure the force of the pressure exerted on the screen “ , explains the expert.

Can it change the way you use the phone? Will it cost used? We talked about doing gestures with his knuckles on the screen to open the browser or launch the camera, for example …

“At the end Huawei think how people can use technology in the most natural way possible.Technology surrounds your life and we want the phone quickly understand what humans want to do at that time. Touch is the way we relate, is what makes the use of a smartphone. We have now developed a new twist, as knuckles or the third dimension that gives the force sensor … so get your phone to make the functions you want the user. “

Increase sales

Huawei’s global sales are growing and conquering new markets. What are your predictions?

“In the first half of the year we shipped 48 million units and the target for the year it is to reach 100 million. I can not disclose sales targets for next year, but we expect a growth of 20 to 30 percentWe are growing fast and we hope to gain market share worldwide. This encourages us to invest more. “

If you ask people on the street, most have few marks on the head and probably before Huawei mention others like Samsung, Apple, LG or Sony, that’s at least what would happen in Spain. How do you intend to become a trusted brand and more familiar to the consumer?

“Huawei has 27 years of history, but we’re only selling to end-user devices 10 years. Six or seven years ago we were not so focused on selling smartphones, so we took very little time communicating directly to consumers. But, although we have much to do, we are acquiring a lot of experience with our partners in the media, distributors, etc. So we should not invest only in products but also in marketing and communication. We not only have the best products, but the best customer service. We want to be a ‘Brand loved’ people know more and we know our products. “

Companies have very different strategies, some offer an extensive range with dozens of models for low, medium and high; and we have others read Apple, which focus almost one flagship model. What is the strategy of Huawei in this regard?

“I think consumers have different needs when buying a new smartphone, we can not only provide a mobile for everyone, people are very diverse. Very different people have different needs. We like some mobile flag, our beloved Mate 7 S Mate now and teaches is also our P series, which currently dominates the P8. After those two terminals have a range a little lower than the G-Series we are now just presented the G8. But of course we also offer a range of entrance. Our idea is that there are few models, for example about 4 low-end, midrange and 4 or less similar number of high-end. We believe that this is the way. “

The key to success

What is the characteristic or feature that customers value most when buying a new phone: camera, processor design..?

“For a Smartphone, the key to success lies in the basics, which is able to make calls and surf the Internet with fluency and quality. We put much effort in this chapter, that the voice heard clearly, that there are no cuts, we sail with speed … However, this is the most basic, is never mentioned in the consumer market studies. The camera, for example, is essential as it has replaced traditional cameras in many cases, but the design is increasingly important. “

Some think that the current generation of mobile phones, large touch screen and good camera, has peaked. When new models come only slight improvements are noted, but in essence starting to look all too terminals regardless of brand. When do we expect a big jump, as graphene-based mobile, flexible, projected onto the skin, etc?

“Not only do we invest in products they invest heavily in technology future technology to improve battery performance and flexible displays. Be prepared for the future, we have many discussions with our partners and we are working on those special features to come. However, today’s phones and they will arrive soon work with other companies on the possibility that they are even thinner, use new materials and phones vary its shape. There is room for improvement. “

A fad?

They are wearables a fad or people will use them in your daily life?

“As smart watches are only beginning. They complement the phone, allow us to read messages or emails us and measure the hours we sleep, run or work. When you ask the consumer is clear that demand more features in these devices, the key is to see what those functions are. “

What about the car connected, it is also a way that can bear much fruit? After all it is a machine that too many people use every day.

“We Cube technology to put the Internet in the vehicle, we will provide access and Vokswagen brands like Audi and we’re doing a lot of R & D in this area. The idea is that you can do from the comfort of the same car can do on your mobile phone. “

Order a pizza?

“Of course, order a pizza. And many more things, “ concludes Kevin Ho.

Most urban air purifying World

Roosengaarde (1979) told Efe in an interview that the project is “a tower of about 6.50 meters tall, which absorbs polluted air, purifies it and returns clean air only to spit.”

Dutch artist Daan Roosegaarde designed as purifying air in the world, a project which will open in Rotterdam in September, which will allow ionic technology through the cities clean air pollution.

This tower, which for now is only a prototype, will open on September 4 at the new facilities of Roosengaarde studio in Rotterdam, with the idea that later trip to Beijing and possibly other cities like Mexico.

“The agreement we have reached with the City of Rotterdam is the city acts as a laboratory where all the ridiculous ideas that have, whether by orders or my initiative as an artist, are implemented here first,” he said.

This is the city become “a platform for new ideas” that encourages “the local economy and creativity,” he added Roosegaarde.

Although “Rotterdam has no serious pollution problems will be where we will test this new technology” to other governments and institutions to check their operation, and later to “travel to cities like Beijing, who have already started negotiations,” he said .

He added that one of the cities he is visiting Beijing, which faces a severe pollution problem that the authorities want to solve as soon as possible.

According to the designer, “they have a program of 165 million euros for the cleaning of the air of the city,” although he said that for the moment “all we are doing is moving factories to less populated areas.”

He added that in his opinion “need a more innovative solution and why they are interested” in the project, “but first I want to see that it works.”

For the artist, whose primary mission is “to design prototypes of the smart city of the future” is fundamental “learning from nature” and then “apply this knowledge in the design of buildings, public spaces, road construction or smart street furniture “.

Also “Glowing Nature”, an initiative in which the company works with Bioglow and the University of New York, and that is to “create genetically modified plants that light illuminate the city at night without street lights, cables, or solar panels “said Efe Roosegaarde.

The work of this young and innovative Dutch artist, which he said is “techno poetry”, is to design and invent “pragmatic and poetic projects” having technology and nature for the design to be “more human, more sensitive.”

“All my work begins in art is poetry, and usually is linked to an obsession, but do not want to put the pieces in a museum but I want to work with people … Create intelligent landscape of the future,” he said.

He noted that now their concern is that “children in Beijing who can not play outdoors in the amount of contamination can.”

His anti-pollution project is completed with a collection of jewelry design with contaminated air particles.

“If we consider that a large percentage of air pollution is coal and that this material gets diamonds at low pressure, with waste polluted air will design high-end jewelry whose benefits will be aimed at improving the draft,” he said.

That aspect of the project “it expands its potential” because besides being technological innovation, it is also “social innovation” he said.

Do the speed reading Apps?

A team of researchers from the University of San Diego shows that when we use software to accelerate reading worse grasp the meaning of the text. The reason is that normally imperceptible eye movements performed in milliseconds to reread some words that have already passed and thus better understand what we read, which is not possible in applications designed to read between 500 and 1,000 words and are gaining great popularity .

In a fast-paced society, the need to process information as quickly as possible and presenting that information in small format screens for example, new smart-watches has brought success to various applications that promise to improve our reading skills . Spritz is the pioneer software in major mobile platforms, but we can already find many other Apps, which work in a similar way.

The method is to briefly show each word individually, marking in red one letter in particular that guides the reading. In theory, can read between 500 and 1,000 words per minute thanks to what is technically known as “fast serial visual presentation” (RSVP, its acronym in English). Before the fury of these applications, a team of researchers from the University of San Diego has conducted an inquiry to check whether this way of reading helps reading comprehension. In other words, if there really learn what we are reading at speed. In an article published in the journal “Psychological Science” Elizabeth R Schotter and his colleagues faced 40 university students without visual problems and other standard texts where words were transformed into X as the students read them, as happens when they disappear display in speed reading applications.

The results of the research show or at least question the usefulness of the programs as Spritz. “These applications are not useful because they deprive the reader control the sequence and duration of access to the words. If you do not understand something, there is the opportunity to turn back, “said Schotter. In addition to re-read consciously, the authors explain that by 10 to 15 percent of the time reading, eye movements made to the text and read. The reasons may be varied, like returning to a word that had jumped the eye if want, something that happens on occasion, or simply the way back, which occurs in milliseconds and of which we are unaware, can better understand the sense in the context of the sentence. By not allowing applications quick read that possibility, the researchers conclude that they have “drastic negative when it comes to understand what we are reading consequences.”

Meanwhile, the “fathers” of the application Spritz say that “we are reinventing the way people read to remove barriers associated with traditional reading on mobile devices. Reading has never been easier, efficient and effective in such small screens, “he said co-founder and CEO of the company, Frank Waldman.

So what is the secret to speed read? To Schotter recipe it is clear. “Practice, practice. As with any complex skill faster you will be based more and more readers read. Because reading requires coordination of various cognitive systems and practice is the only way to improve, “said the researcher at the Department of Psychology at the University of San Diego in California (USA).

The new rules allow flight drones studies in urban areas

The new regulation on drones, which reinforce adopted in July 2014, studies allow unmanned aircraft flying up to ten kilograms in urban areas bounded or a safe distance from buildings and people.

Currently, the State Aviation Safety Agency (EASA) is considering the arguments presented to the Royal Decree that updates the rule that calculates, will be ready by 2016, explained to EFE sources of this agency under the Ministry of Development.

According to future legislation, the flights would have to meet specific security measures, and limit its use to up to 100 meters away and 120 meters between drone and pilot.

As for aircraft up to 25 kilograms option that can fly in uncontrolled airspace beyond the visual scope of the pilot we are shuffled. At present the use of drones in urban areas is not allowed and may only drive outside towns, buildings or buildings, meeting people outdoors and uncontrolled airspace.

He met last week in Riga -a proposal from the Latvian presidency of the EU European aviation to exchange views on how and under what conditions, the drones can help create new opportunities for the industry in Europe. At this meeting were representatives of the European Commission and the Civil Aviation EU Member States (Spain was represented by EASA).

The meeting pledged that European regulation ensures compliance with all ” security conditions for the safe and sustainable emergence of innovative services drone “and to” help the industry properly thrive off the concerns of citizens . ”

All drones have to be used in daylight and in good weather conditions, in addition to being far from population centers, buildings or buildings, meeting people outdoors and in uncontrolled airspace. For management, you need to have a license or notification to the Aviation Safety Authority (EFSA) regardless of the size of the drone.

There are several options as have or have had in the last five years any pilot license or obtain a certificate issued by a training organization approved by EASA . The latter is one of the most popular options after regulation in our country in this sector, in which companies have emerged offering courses that enable users to use.

EFSA distinguishes between three types of drones: less than two kg, appliances up to 25 kg and over 25 kg . The lower 2 kg drones are the only ones who can fly beyond visual range of the driver and can reach a maximum height of 120 m (400 ft), but should be subject to the scope of the radio emission of the control station.

You do not need a course or certified by EASA, but it must issue to the Aeronautical Information Services a notice to individual users who are making use of the airspace in the time that is going to produce the flight.

The ships of up to 25 kg (also classified as Class LAPL) do not need a permit for the pilot, but the pilot has to make a responsible statement EASA to use along with a notice five days before your flight. The drone must be within visual range of the pilot, to a maximum distance of 500 m and a height above ground of 120 m. To obtain photographs or filming requires special permission.

The drones weighing more than 25 kg (Class 2) are those who need more demanding permissions. The pilot needs a basic or advanced certificate issued by a training organization approved after passing a course, added to the EASA authorization to start business. Finally, you need a record of registration of aircraft and have EASA airworthiness certificate.

Pilots must always be allowed to fly these devices. While in urban areas the flight is not allowed in fully enclosed spaces (including the roof) are not subject to the jurisdiction of the EFSA, so that holders of the enclosures are responsible for the drones are authorized.

Max Planck scientists try to sequence nuclear DNA from Atapuerca

Max Planck scientists try to sequence nuclear DNA from Atapuerca

German scientists Max Planck Institute for Evolutionary Anthropology are working to sequence nuclear DNA from remains of hominids removed from the Sima de los Huesos, Atapuerca, in Burgos, with an age of 400,000 years, he reported one of the co-directors of the deposit, Juan Luis Arsuaga.

Speaking to reporters, Arsuaga, who is also scientific director of the Museum of Human Evolution in Burgos, director of the Joint Center Evolution and Human Behavior, formed by the University Complutense and Carlos III Institute of Health, has stated that it is a “complex work” that will take years to be completed.

However, he explained that the first steps of this research can be found on a “relatively short” period and will be “striking” for their contributions to meet characteristics of these hominids.

The collaboration between the Atapuerca team and allowed the Max Planck Institute in September 2014 published a study of the mitochondrial DNA of a prehistoric bear.

In July this year took a historic step by sequencing mitochondrial DNA from a femur of the Sima of the Bones.

Arsuaga has explained that this is a complex process because the mitochondrial DNA can have about 60,000 bases, although the nuclear DNA has several billion.

Homo Naledi, a new species of Homo Australopithecus traits

Homo Naledi, a new species of Homo Australopithecus traits

An international team of scientists described for the first time Homo Naledi, a new species of hominid that has features of Australopithecus and that could be the oldest specimen of Homo.

Homo Naledi was discovered in 2013 in the chamber of the cave Dinaledi Rising Star of Africa (near Johannesburg) and their remains were among more than 1,550 fossils, which makes this site in a paleontological treasure.

Here the bones of 15 individuals of the same species were found, which has documented and describe the skeleton of Homo Naledi in great detail.

A complete description of this new kind of hominid is published today in the journal ELIFE.

But how was this guy?

“Homo Naledi is a mosaic of characters form, has a trunk-shaped funnel, not barrel shaped like men today, but like a pyramid, a feature of the Australopithecus or the great apes current as the chimpanzee, “he told Efe researcher Museo Nacional de Ciencias Naturales (MNCN) and co-author Markus Bastir.

Homo Naledi, a new species of Homo Australopithecus traits 1

In addition, “has a small skull, the shape of the first representatives of the genus Homo habilis or as erectus, and a cranial capacity very small, about one third of what occupies our current brain,” he adds.

However, although it is very robust and has a skull and primitive trunk, limbs are “virtually identical to those of modern humans.”

His hands are capable of handling objects that have men now but his fingers and phalanges are curved, which, according to the anatomical experts, means that would be adapted to live in an arboreal habitat, but at the same time, “both wrist bones as palm are very modern, indicating that, although no tools found at the site, with that anatomy could use them well “, clarifies the researcher.

“The feet are also like ours, except that the fingers are slightly curved, which means they would be adapted to living in trees and on the ground.”

Overall, this homo, 1.50 meters and 50 kilos, has features of Australopithecus but is more graceful than this species, which will bring them closer to the first homo.

As for the dating of the fossil, experts still do not dare to give a figure because, the absence of other fossil animals is complicating the analysis but “a team of paleogeologos is analyzing sediments deposit to make a rough estimate,” he explains Bastir.

The oldest Homo World

However, “based on morphology, analyzes place this fossil among the first homo-about 2.5 million years and, if more recent off (less than a million years), would be the test Africa coexistence of species of the genus Homo very different from each other, “says the researcher.

“We are facing a great opportunity to obtain information that will allow us to rebuild our complex evolutionary history” and clarify certain questions such as “whether the reservoir 15 bodies were deliberately placed by their counterparts in the House of Dinaledi”.

Rising Star Workshop

To discover all the secrets of this deposit, the South African government in 2014 organized a workshop entitled “Rising Star Workshop”, largely funded by National Geographic, that allowed scientists around the world and all specialties could share data.

“It was very generous of the discoverers of the site open research paleontologists worldwide, which has served to create a multidiciplinar equipment and give a chance to young researchers at the beginning of their careers,” he says.
