Future

The US space shuttle Endeavour has arrived at the International Space Station (ISS).The orbiter, which is making its last foray above the planet, will spend just under two weeks at the platform.It is delivering a $2bn particle physics experiment and a tray of critical spare parts.On its return to Earth on 1 June, Endeavour will be prepared for public display at the California Science Center in Los Angeles.”


The news tell us how much science is improving day after day. I remember when I was a child, our televisions didn't have a remote control to change the channel. So, when I wanted to change it, I had to stand up of the sofa, walk towards the tv and press the channel button.

I think that we are living an important period of time of huge changes, in which the society members are changing their minds. In my opinion, there will be an important metamorphosis which will transform the world we live in. This change is happening nowadays although unfortunately we are on crisis. These years, teenagers, adults and old people are seeing disasters such as the Japan nuclear crisis or the earthquake in Lorca, Spain.

In the new I have chosen, we can see that although we aren't living the most wonderful actions of humanity, some of us want to continue investigating with Science. Maybe, these ressearches will help us to find out a solution for practical and simple problems like somebody did in the past when he or she invented the remote control.

BLUE= Improvements

Why Asia's nuclear tigers can't stop building reactors


... Nuclear power has long been considered a promising solution here. Although the global nuclear energy industry suffered a dark period after the catastrophes at Chernobyl in Ukraine and Three Mile Island in the U.S., it's staged a comeback even as environmental concerns mount.

Enter Japan's nuclear crisis. Suddenly, the growth prospects for nuclear energy in Asia have been top-sided. On Wednesday, China announced it would halt all new nuclear plant approvals -- about 40% of the planned projects in the world....


In this new we can see how much energy need our society, that in our times; when the nuclear powers are on a crisis period, we can't stop building reactors...
A few years ago a lot of people thought that nuclear energy was the final solution with our energetic problems, they think that this energy was clean and it have more advantages than drawback... Nowadays the same people who was in favor of this energy, these days are against that.

Humans are very impulsive, we only think and see what we have in the front of our eyes...

But some times in this planet appear supermans, like Albert Einstein, Friedrich Nietzsche, Newton, Plaó, and others whose ideas revolutionized our world. These class of human must be the spokesperson, to show us what is the correct way to continue here, to preserve our world.

In conclusion I think that the most effective solution is think more and spoke less than today, to find the way which doesn't destroy us... But this isn't possible on a country where most of the people prefer to spoke about football than science...

Graphene

Two scientists have shared this year's Nobel Prize for Physics for their "groundbreaking" work on a material with amazing properties.
Andre Geim and Konstantin Novoselov, both at Manchester University, UK, took the prize for research on graphene.
Graphene is a flat sheet of carbon just one atom thick; it is almost completely transparent, but also extremely strong and a good conductor of electricity.
Its unique properties mean it could have a wide array of practical uses.


Probably this discovery will revolutionize our world, the world that we know will change completely ! This will be caused by the graphene properties, It said that unique properties mean it could have a wide array of practical uses, like on mobiles, computers, cars, airplanes, and some future nanosiuts which nowadays we play in our video games. On of the most important properties are:

*conduct electricity
*hardness
*weight
*resistance
For all of this qualities I think that this material will change our world, I hope that for improve our lifes and help us to do the definitive jump to sapce, which is the next place where human will live.

Libya revolt

This new explain the evolution of Libya revolt. The Libyan oil terminal town of Brega has been targeted with air strikes, sources in the town said:

The strikes come a day after clashes between rebels and government troops in the town in which 14 people died. Forces loyal to Libyan leader Muammar Gaddafi took control there on Wednesday morning but were forced out by opposition fighters later in the day.

Although that Col Gaddafi has lost control of the eastern half of Libya during two weeks of unrest, he has vowed to fight on.

In this new the only thing that we can see is the corruption and wickedness of Muammar Gaddafi, who have the same personality than Egyptian president Hosni Mubarak. Their objective are be the most rich and “happy” people in the world independently of situation in their country, like human rights or their remorse. In my opinion the most surprising of this new, are the time which normal people can be in the situation of injustice, inhuman conditions.

But the worst is that countries like our, which are considerate just, and respectful, can see all of this situations and our reply is simply do the same routine than a normal time, like all of this don't exist for us...

Antimatter

"Researchers at Cern, home of the Large Hadron Collider, have held 38 antihydrogen atoms in place, each for a fraction of a second. Antihydrogen has been produced before but it was instantly destroyed when it encountered normal matter. The team, reporting in Nature, says the ability to study such antimatter atoms will allow previously impossible tests of fundamental tenets of physics. The current "standard model" of physics holds that each particle - protons, electrons, neutrons and a zoo of more exotic particles - has its mirror image antiparticle. The antiparticle of the electron, for example, is the positron, and is used in an imaging technique of growing popularity known as positron emission tomography"

In this new scientist explain how they can found the antimatter, this is very important for evolution of science. Since some years the scientist knew the existence of this "thing", the antimatter jointly with matter can generate a lot of energy. I think that in this new we see the evolution of science, in my opinion in this century we will observer a lot of improvements in this issue.

On the other hand this type of experiment are very expensive, the creation of antimatter cost around 60.000 millions and moreover the conservation of this type of matter are very complicated cause we can put togheter. They must save with electromagnetic and complex camp.

I would like to express my opinion in reference in this experiment, I think that we must invest time and capital in this part of science because our future depends of the capacity of our minds.

Obama warns nations not to rely on exports to US

The new of BBC explain that president of United States, saw the opportunity to create new jobs back home. He was speaking in Yokohama in Japan on the sidelines of the Apec summit. There Mr Obama explain that the country with large surplus must take steps to boost domestic demand. President Obama said the economic crisis had shown the limits of depending on US consumers and Asian exporters to drive growth.

In my opinion this new reflect the fear of important economic potency, in this new EEUU, to the new and growing potency like China, which can grow because the country works as only one, all for homeland. I think this because the commercial and exporting politic of China are very aggressive, for example in the harbor of Barcelona the police find a lot of different types of metals in a “transporting boat” which will go to China. There isn't any problems if this metal are normal but the metal was stolen by different thief.

In conclusion I think that in the future this potency cause a lot of problems, our task will be find a solution!
