Graphene is a material that comes from graphite and has an atomic structure composed of carbon and hydrogen, arranged in a honeycomb structure and has amazing features, such as: high thermal and electrical conductivity, flexibility, hardness, resistance, lightness, etc. And if it were not enough, Graphene is also believed to have the ability to repair itself, is it not amazing?

Can you imagine screens a few millimeters thick? Or batteries that last much longer? Super processors barely heated? Graphene has many applications in all fields of modern science. One example is in biotechnology, through which scientists could make progress in the fight against terminal illnesses or even implants to replace damaged tissues at a cellular level.

Energy consumption that comes from fossil fuel worldwide would change drastically due to that graphene is able to absorb sunlight and transform it into electrical energy, allowing a family to be energy self-sufficient in solar periods. The use of Graphene contributes to fight against climate change.

To conclude, Graphene seems to have no limits. Every day this material is investigated, discovering new and amazing qualities that surely in the near future will make humanity take a historical leap in its evolution.

It is probable that you have ever heard what a smartphone is or even you have one. If not, you’d better catch one as fast as you can, cause once you start discovering the wide range of apps (applications), widgets and tools these devices offer you, you won’t be able to stop using them!

First of all, I would like to introduce some of the most-used apps which have been developed to keep you in touch with friends. They let user access social networking sites, like Facebook or Twitter, and communicate wherever you are with the rest of the world.

At this stage, I must mention Whatsapp Messenger. This cool app is a ‘must’ in every smartphone. Once installed on your device (Android, iPhone, BlackBerry and Symbian OS are supported), it allows you to exchange messages, photos and videos with all your contacts who run Whatsapp too, and totally free! The only requirement to make it work is a data connection, so it’s better if you contract a data plan with your existing cellular service or use a Wi-Fi connection and then say bye-bye to SMS!

Our classmate Cristina has written this blogpost that continues after my words. It’s really good, so I hope you enjoy it:

It seems that we have to be patient because Apple is delaying the international iPad launch.
The company announced  that they had to delay the international selling of  the new iPad tablet computer to the end of May, due to the strong demand  in US. The sellings were so high that many stores were collapsed so the company had forced to advise the selling by Internet.

Apple said “we have sold 500,000 iPads in the US in the first week after the April 3 launch of the device, the demand is far higher that we predicted that it will probably exceed our supply”.
The company has predicted to sell from 1 to 5 millions of iPads the first year, although, the demand can reach 10 millions, just in 2010.

At present, in US, it is available with Wi-Fi, but by the end of April there will be 3G models.

Therefore, people from Spain, UK, Germany, France, Italy, Switzerland, Canada, Japan and Australia who want to enjoy an iPad will have to wait a little.
