Us new thrust to break China Firewall Internet (AFP)

WASHINGTON - plans for the United States to pump millions of dollars in new technology to break censorship of the Internet overseas in a crackdown on dissent in China, said officials.


Representatives of the State Department said that they would give $ 19 million to efforts to avoid the Internet in China, the Iran and other authoritarian controls that block online access to politically sensitive material.


Michael Posner, assistant Secretary of State in charge of human rights, said the funding would support a cutting-edge technology that acts as a "slingshot" - identifying equipment that countries are censorship and launching back on them.


"We will respond with new tools." It is a set of core. "We are trying to stay a step ahead of the cat," said Posner.


The announcement was made shortly after the United States and China wrapped in large annual discussions in which the Secretary of State Hillary Clinton shows exasperation domestic repression intensifying criticism of Beijing.


China routinely blocks sites that present points of view on topics such as the head of Tibet in exile of the Dalai Lama, banned Falun Gong spiritual movement and the Suppression of Tiananmen Square in 1989 on the informal pro-democracy demonstrators.


More recently, the Chinese authorities blocked the search for "Hillary Clinton" after that she gave a freedom Internet Champion of speech and for "Jasmine", an allusion to the pro-democracy uprising sweeping the Arab world.


"Indeed, we will be forwarding back information that Governments were initially blocked," Posner said.


"This can be done by e-mail or posting on blogs or RSS feeds or Web sites that the Government did not understand how block,"he says."


The funding comes from $ 30 million, the US Congress allocated in the exercise of the freedom of the Internet.


The failure until now to spend the money leads legislators to accuse the State Department of bend to China. A recent report of the Senate Committee called for another Government to be put in charge of these funds.


Supporters of the Falun Gong developed the so-called Global Internet Freedom Consortium, a software to evade Chinese Internet firewalls which was so effective that Iranians sought it during 2009 protests against the regime.


Posner said that the State Department would not identify the recipients of funding due in part to "security reasons".


Another US official who requested anonymity said that the State Department has received requests for funding totalling $ 180 million and that he chose those who seemed to be more effective.


Funding grants still needs the green light from Congress, but the official expressed hope that it would increase rapidly.


Clothilde Le Coz, Washington Director of the media rights Reporters without frontiers group, welcomed the new and its timetable, saying that China is imprisoning 77 people for their activities on the Internet.


"It is good news to know that Internet users more will certainly appreciate to get their word out," she said.


But she said that the workarounds for Internet tools were a "symbolic" the broader issue was ensuring freedom of expression.

In a speech in February, Clinton called Internet "the 21st century public space" and is committed to ensure that it develops in a manner that allows freedom of expression and association.

However, she also criticized activist site WikiLeaks for publishing secret us cables. She accused WikiLeaks "theft" and said that the question did not contradict the commitment of U.S. open Internet.

MODULATORS of Graphene could break the limits of network speed

Optical fibre networks are at the forefront of Internet record-setting speed. Now, scientists from the University of California, Berkeley have developed a modulator of Graphene that could push the curve forward by a bond multiplied.


The listening team electrically layers thick carbon atom to absorb light at wavelengths used in data communications. The middle of Graphene was then shaped MODULATORS and placed in cables and optical network tiny for light transmitting data outside.


"Graphene allows us to modulators that are incredibly compact and potentially engaged at speeds of up to ten times faster than that current technology allows," explained Professor of engineering UC Berkeley Xiang Zhang, who led the research group. "This new technology will significantly strengthen our capabilities in high-speed optical communication and computing."


Data transfer speed depends on the speed with which the modulator can pulse light. Indoor optical cables, a modulator switches of transparent and opaque than its electrons are charged. Researchers have discovered that modulator of Graphene reached a speed of 1 gigahertz modulation and theoretically could reach as high as 500 gigahertz (500 billion cycles per second).


The tiny size of 25-square-micron of the Graphene modulators, optical cables would finish with modulators of measurement in millimetres used today. Indeed, optical cables could be stalklike which could potentially reduce their ability - the ability to hold an electrical charge - and lead to faster data transmission.


Colleague Zhang Feng Wang, assistant professor of physics and head of the Nano-optical ultrafast Berkeley group, added that the Graphene could be granted to other frequencies. "Graphene can also be used to modulate the new frequency varies, as medium infrared light, which is widely used in molecular detection.".


Graphene itself is already a highly regarded in electronics since its discovery in 2004. as it is flexible, the crystalline material more thin and more strong, pliable as rubber, compatible with silicon and an excellent conductor of heat and electricity. In addition, the research applied material Graphene is producing cheap and easy.


Liu Min, a researcher postdoctoral fellow in the laboratory author and co-lead for Zhang of the elaborate study on "the graphite in a pencil can provide enough Graphene to make $ 1 billion optical modulators.".
