 A researcher at the University of Southern California say they managed to calculate the amount of information that is stored by the human race. And the numbers are huge: 295 exobiti. That means very many posts and comments on Facebook and movies more or less "broadside", and much literature, so that the figures include analog information.
If one grain of sand is a single information, then each person in the world of information is stored a quantity of 315 times higher than the total number of grains of sand in the world, "said Martin Hilbert scientist. "This is the first series of studies aiming to quantify the human race's ability to manage information," said HilbertInainte non too enthusiastic about these numbers is good to know that those 295 exobiti represents less than 1% the information stored in the DNA of one person.
According to researcher, the digital era began in 2002, the year when digital storage capacity worldwide has exceeded the total capacity of analog. By 2007, 94% of our memory is in the form digitala.Se seems that same year, the world of information sent via zetabiti 1.9 technologies such as television transmission or GPS. That equates to 174 information daily from newspapers read by one person. "These figures are impressive, but at the same time, small in magnitude compared to the nature of managing information." unimedia.md

 It would appear the title of some great science fiction film projected on the big screen, one of those movies where the protagonist tries to fight against nature to save himself and his loved ones from a fate far from comforting, but unfortunately this is not the title of a movie, and who has spoken this sentence is not a television commentator during the screening of the trailer, but it is a statement from NASA, the U.S. space agency.
"A solar storm (also called a geomagnetic storm) is a disorder of the Earth's magnetosphere, a temporary nature, caused by solar activity. During a solar storm the sun produces strong emissions of matter from its solar corona generating a strong solar wind, whose high-energy particles are to impact against the Earth's magnetic field from 24 to 36 hours after the issuance of coronal mass.
This only happens when the solar wind particles travel towards the Earth. The solar wind pressure changes as a function of solar activity and these changes alter the electrical currents in the ionosphere. Magnetic storms usually last 24 to 48 hours, although some may last for several days. "
This quote, from the famous and important free encyclopedia Wikipedia provides us with a unique and detailed definition of solar storm, which is essential to continue our discussion. Millions of people without electricity in 2012, food and medicines that go bad in the fridge turned off, and satellite phones out of order. A scene from "Day After" that could be declassified in the "catastrophic", except that the alarm comes from NASA and the National Academy of Sciences. And in the villain that threatens civilization, for once, there are human activities, pollution and global warming. The enemy by surprise is the Sun, the creator of life on Earth, with a cough could knock the infrastructure on which the West prosperous.
Since December, the Sun's activity is slowly increasing. Our star changes its magnetic field every 11 years and at some point you reach a peak of phenomena (solar flares and coronal mass jets) from which emanate large amounts of energy and radiation. These jets can reach Earth, giving rise to geomagnetic storms. The atmosphere protects us, the direct effects of solar storms on health is negligible, but their impact on socio-economic structures could be disastrous.
Astronomers observe these phenomena since 1859 when a geomagnetic storm of extraordinary proportions, in addition to making possible the observation of polar auroras like those in Italy and Cuba, he set fire to some of the telegraph wires in Europe and the United States. In May 1921, another storm caused a series of shorts, bringing down power lines and telephone across the Atlantic. But what if such events occur today that an entire civilization was founded on electricity and telecommunications?
The response of experts is far from comforting: "Electricity is the key technology of modern society, from which all others depend, and other infrastructure services," reads a 132 page report commissioned by NASA the National Academy of Sciences. "If the storm of 1859 to happen today, we will see an enormous social and economic devastation." In 1989, six million people in Quebec were without power for nine hours due to a geomagnetic storm ten times less powerful than that of 1921. According to John Kappenmann, co-author of the report, if an event such as a repeat of '21 .....

 Moldova back to try to get rid of 6 aircraft MiG-29A Fulcrum-announced to the press spokesman of the Ministry of Defence, after opening three auctions in 2010 that roused the interest of one potential customer. Base bid, $ 8.5 million.
The new sale was opened on 1 February, and will cover aircraft built in 1988 and completely updated at the end of 1990 in Belarus, which is currently grounded in the need of repair at a cost of around 30 million dollars, figure that the Ministry of Defence does not want to spend preferring to put up for auction. The six aircraft in question are part of a batch of 32 units inherited from the army Moldova after the collapse of the then Soviet Union, most of which was purchased by the Pentagon to ensure that the planes did not fall into hostile hands.
The Fucrum (NATO code) is an air superiority fighter for the Russian Soviet originally produced by the Mikoyan-Gurevich. Twin-engine high-performance, limited only by the lack of autonomy. The project was started in the early seventies and entered service in 1983 the Soviet air force. avionews.it
