Solar Panels has been improve with virus

Viruses can help build better solar panels that capture and process more efficient solar energy into electrical energy. This has been demonstrated at a Research Massachusetts Institute of Technology (MIT for its acronym in English) that has used a type of virus to restructure the carbon nanotube solar panels and increase their efficiency by 30 percent, from 8 to 10 , 6 per cent.

That the efficiency of solar panels is still well below their potential is more than evident. What was not known so far is that something so small and is sometimes dangerous as a virus, could hold the key.

The virus called M13 coordinate gets rolled carbon nanotubes in graphene that make solar cells so that the electron transport more efficient and therefore produce more electricity. Basically, the M13 gets the two types of nanotubes (semiconductors and cables) that form the structure of solar cells, do not interfere with each other and impede the flow of electrons, but the structure becomes smooth.

Grätzel cells
Each virus controls between five and ten nanotubes, using about 300 proteins. In addition, viruses have been genetically modified to produce a layer of titanium dioxide, a key component in Grätzel cells, a type of structure they use this compound to improve electron transport.

Xiangnan Hyunjung Yi Dang, MIT students along with Professor Angela Belcher successfully tested this new virus in Grätzel cells, but explained that the technique could also be used for other types of solar cells, including organic.

The virus also solubilized nanotubes making them easier to incorporate the solar panels at room temperature, significantly reducing the manufacturing cost.

Movies on YouTube after a deal with Sony and Universal

The streaming video service YouTube would be close to allow users to watch movies on your site. Some of the largest companies in the industry, such as Sony Pictures Entertainment, Warner Brothers and Universal, will lend their productions for this project, which could begin this week or next.

The movie industry is finding new ways to distribute their content and prevent piracy affecting this sector. There are several initiatives in this regard, as the service offered by Apple and Netflix, a company with a strong position right now in the online video market. Even Facebook has reached an agreement with Warner to rent movies through the network.

However, the most visited site in streaming video on the Internet, YouTube, I still had some way to go, take some time despite offering movie rentals through its site. Now it seems that the platform gathers momentum in this market. According to information published in The Wrap, the Google website has reached agreements with Sony Pictures Entertainment, Warner Brothers and Universal to offer access to their productions.

Apart from these big companies, YouTube would have signed other agreements with more independent producers such as Lionsgate and Kino Lorber, sources close to the negotiations. In this way the site would be ready to launch its movie rental service this week or next.

The agreements will expand the catalog of movies on YouTube, making it a competitive service that can compete with the supply of systems like Apple or Netflix. The great mass of the platform gives users the ability to boost this sector site, supporting a new form of distribution for films.

According to The Wrap, other producers such as Paramount, Fox and Disney have rejected the agreement with YouTube to offer movies through the site. On the other hand, streaming video company has issued a statement after meeting the information published stating "We have been adding more and more titles strongly since we launched the YouTube movie rental for more than a year, and now we have thousands of titles available. Beyond that we do not comment on rumors or speculation. "
Renting movies on YouTube

YouTube videos usually have a short duration. It is a place where you can see larger productions, in fact they tend to be divided into several parts. In fact the platform has never promoted the movie rentals as such.

At present the company has seen the business niche, according to a source close to the deal, manager of one of the producers who signed: "We believe this begins with VOD (video on demand), but will be expanded to include sales over time. We are very excited because we are happy to see new participants in the transaction model rather than a subscription model. "

It is unclear how YouTube will charge for the rental of films, but behind it is a market of 130 million monthly users to monetize the new service.

The future of maps on the internet

There is no doubt that the map uncharted territory is man's best friend. To this end, Nokia has released a tool that promises to raise to the next level guidance systems on the web.

"Have you heard the news? The world is not flat, it's actually quite three dimensional. So what about online maps? are flat or three too?", published in the company's blog announcing the new product.

Easily accessible from mobile devices, Ovi Maps features 3D models of major cities around the world, including Los Angeles, San Francisco, New York, Miami, Toronto, Madrid, Prague, enabling the user to explore the three-dimensional view after installing a plug-in in your browser. http://maps.ovi.com/3d/index.html

The technology used to generate these maps requires each object captured from 100 different angles, then adds texture using an image processor.

Panic at playstation network.

Sony Network playtation fell, and while his desperate attempt to find out exactly responsible for why, the more than 70 million registered users is pulling their hairs watching the error messages that throw their PlayStation Portable and PlayStation 3. The case, which has already been a day of existence, seems to have roots in an attack by hackers and according to spokesmen at the disaster of entertainment, the problem may be one or two more days to resolve.
Users of the online service for Playstation 3 and Playstation Portable-eat breakfast or snacks according to the time zone, a few days with various error messages on gaming services, including streaming video provided by Sony through its platform . Angry at the situation and above all flooded out of frustration, users attended a show of indifference, because since Sony gave no sign of life for a long period, which ended several hours later with a notice more than obvious in blog: Sony PlayStation Network had fallen and services do not respond at the moment. Since Sony is urged patience and then verify and try to detect the cause of the problems may be suspected of an attack by hackers, the spokesmen announced that the network would remain closed for a day or two before servicing and return to players the field of play.

Lindsay Lohan Back to Jail

This time for 120 days, a judge in Los Angeles he downgraded on Friday to actress Lindsay Lohan the charge that was pending for stealing a necklace of $ 2,500 from a jewelry store in Venice, a misdemeanor, but two hours later put to jail for 120 days parole violation that was pending for driving drunk in 2007. She also must meet 480 hours of community work, but his lawyer said he would appeal the decision.

Successful quantum teleportation

A team of researchers from the University of Tokyo in Japan and the University of New South Wales in Australia, led by Noriyuki Lee, has succeeded in teleporting non-classical wave packets of light from one place to another. This, simply put, means that for the first time it has managed to send data from one site to another instantly, without using the "slow" classical photons are capable of exceeding the speed of light. According to the authors of the paper, the system could be used in the design of quantum computers faster and capable of delivering information securely and instantly.

For years, scientists looking for ways of making quantum teleportation provided by the laws of physics in a real device. The "small print" of quantum physics says that under certain conditions, it is possible to transfer information between two points instantly, without the limitations imposed by the speed of light. But one thing is that something is possible (or permitted by the laws governing the universe) and quite another to build an apparatus that becomes a reality. There have been several experiments, some surprising results, but it seems, have been researchers at the University of Tokyo in Japan along with the University of New South Wales in Australia, led by Noriyuki Lee, who have been successful in build what they call "a teleportation device bandwidth and zero dispersion."

The system could be used in the design of quantum computers faster. The system could be used in the design of quantum computers faster.

The results of this work have been published in the journal Science. Basically, what did these scientists was sent from point A to point B a number of quantum-level data expressed by photons. Obviously, the interesting thing about this is that these particles have been used in the same way that profit within an optical fiber, but quantum effects have been used with such strange names as "constraint", "photon subtraction" "entanglement" and "homodyne detection." The result has been a teleportation device capable of teleporting non-classical wave packets of light from one place to another making for the first time to transfer all the information without losing any fragments in the process. In this experiment, the points of departure and arrival (A and B) were relatively close, but the theory behind all this nonsense technological forecast is possible to do the same between any two points of the Universe.

"A teleportation device capable of sending non-classical wave packets of light from one place to another without losing any fragment."

Needless to say that an accomplishment like this, become a commercial device, change the way we communicate. The ability to instantly transfer data (or whatever it is, in a time equal to zero) implies that we may, for example, receive all our emails in a flash, download 1TB of data in the same time, or any else you can think of. But there are some more subtle implications. If this technology becomes part of microprocessors, for example, its processing speed would also increase dramatically, because the signals that travel through it could get from one end to another device in no time. According to the authors of this paper, the system used could be used to design quantum computers really amazing features.

Five tips and tricks for creating messages of 140 characters on Twitter ... and not die trying

If what you have to say takes more than 140 characters, do not say it on Twitter. Open a blog, go to Facebook, talk in person. If you still can believe your message is essential for mankind uses Twitlonger or Deckly, few times a month. A sensible limit may be 5 tweets per month. But still it is best that you can learn to summarize, to use short, back to basics. Express your ideas in 140 characters is more challenging and fun, but not everything. If you like writing and your ideas are complex, many people would love to read you your new WordPress blog, it's time to try. And while you're on Twitter, you can follow these tips and write in 140 characters or less.

1.

Use a shortening of URLs to share a link. It is one of the best ways to save space in a tweet. Any links you share on Twitter should pass through to a shortening of directions, in theory the same Twitter could do it, but in the end is never fully integrated with the tool, not what is the reason. The best are Bit.ly, Ow.ly, and Cli.gs. Goo.gl For more information visit the Wikipedia URL shortening
2.

Use synonyms and abbreviations. There are many opportunities in which you can change a single word by a synonym that takes up less characters. For example, the word "productivity" in some cases can be replaced with "performance," spent 13 characters to 11. When using abbreviations savings is even greater characters. An example might be to use U.S. or USA instead of United States. It is important that you use common sense and do not cut words tweets filled with the ominous language or SMS. You can use a 1 x 2 x two, x and by, equal =, + x again, and so on and so on.
3.

Be simple. In a tweet is always reflect a single idea. Be direct, bluntly, not things too much ornamentation. Not necessary (although it helps) that includes the question say something original in the tweet, it usually appears in the right leg, or a link that says "in response." No need to complicate things, you're not writing an email. No need to say hello, goodbye, or ask permission. Get to the point!

4. Read the message again and check what words you can remove. When you post a tweet do not worry about the limit of characters until you finish writing. If you ran the 140, read again all, try to remove words or phrases that are unnecessary. This works in a high percentage of times. In extreme cases you may want to divide the tweet into two parts. If the two ideas are not connected, wait a few minutes to send another tweet. On the other hand, if you spend the 140 characters, there is no reason to summarize anything.

5.
Begins again. If there is no way to summarize a tweet, erase everything and start over again trying to use other words and a different wording. It's pretty extreme to do this, but it works very well. Sometimes we engage in something and not see clearly how things simple. If the second attempt you can not do better to try a blog.
