The ancient scandinavian trees
http://news.bbc.co.uk/2/hi/europe/7353357.stm
It was know that trees in scandinavia decend from same ancestors which came from south after the Ice Age. Recenly studies of DNA have discovered that there are two types of trees in Scandinavia. The ones that come from south and the new discovered ones that decend from conifers trees that survived last Ice Age. This discover challenges the traditional notions that all trees were killed off by the ice.
One hypothesis is that trees were able to survive on the top of nunataks, the exposed peaks of mountains protected from glacial cover, or in more sheltered areas close to the coast where proximity to the temperate conditions of the Atlantic Ocean favoured the survival of this ancient trees.
After that discover some experts searched and found near scandinavia the oldest tree in the world. This tree seems to be 10.000 years old and it's now holding the World Guinnes Record, it took it form a californian tree that have 4700 years old aproximately.

Hypersonic weapons
Pentagon tests long-range hypersonic weapon
NEWS
The US has test-fired a new weapon which can travel at five times the speed of sound, the Pentagon says.
The missile was launched from Hawaii and reached its target on a Pacific atoll 2,300 miles (3,700km) away in less than half an hour.The Advanced Hypersonic Weapon is part of a programme to build new high-speed long-range missiles.Its aim is to allow the US military to strike targets anywhere in the world within an hour.A statement from the Pentagon said the weapon had been launched using a three-stage booster system, which had successfully sent it into the upper atmosphere over the Pacific Ocean.It reached hypersonic speeds before hitting its target on Kwajalein atoll, part of the Marshall Islands.

I think that's a way to create new weapons without alarming the world, because of the problems to create nuclear weapons the USA is creating weapons with lot of range and speed.
These hypersonic weapons are the new missiles for the 3rd world war. ONU is managing all the military nuclear resources and the United States are avoiding this control with this weapons
Dreams
My dreams
When I was young I used to have a dream. I wanted to be a firefighter but I grew up and my mind changed, then I decided to be a physician.
First of all I wanted to study physics in the University of Harvard. I got this dream until I reached my last school of high school, that year I went to Canada to improve my English. When I went there, they said a thing that stunned me, to study at an American University if you are foreign you need to get an 80/120 in the TOEFL exams, and to study at Harvard you must get more than 105/120.
Then I decided to change my dream, because it’s so hard to pass TOEFL, harder with a good mark.
I decided to study physics, but in Barcelona.
I’m in last year of non-obligatory high school so next year I’ll go at university. That’s why actually I need new dreams to think about.
Well, I have one, that will happens when I’ll elderly I want a rural house on the top of a mountain, alone in Alaska.

Neutrinos faster than the light?
Well last September CERN scientists did and experiment about speed of particles. They concluded that neutrinos may travel faster than the ligth, that produced a that lots of physics critizice the Organization.
CERN because of the important of the discovery and the critics they decided to repeat the the experiment few days ago.
Well first of all I'd like to say that if that's true that will cause lot of problems for the modern physics, scientists said that it will produce some strange thinks in the theoric world we live, such as opportunitis to go to the futurem, new universes, all this stuff.
New technologies will be discovered in the new ages if this conclusion is correct.
