WASHINGTON vans old skool canvas femme , Sept. 14 (Xinhua) -- Scientists have created miniature robots out of DNA that can autonomously "walk" around a surface, pick up certain molecules and drop them off in designated locations, a new study published Thursday in the U.S. journal Science said.

"Just like electromechanical robots are sent off to faraway places, like Mars, we would like to send molecular robots to minuscule places where humans can't go, such as the bloodstream," said LuLu Qian vans old skool canvas , assistant professor of bioengineering of the California Institute of Technology.

Such technology could one day be used for a wide range of applications, including synthesizing therapeutic chemicals in an artificial molecular factory, delivering drugs in bloodstreams or cells, or sorting molecular components in trash for recycling, Qian said.

To create a DNA robot, Qian's team constructed three basic building blocks, including a "leg" with two "feet" for walking vans old skool blanche femme pas cher , an "arm" and "hand" for picking up cargo, and a segment that can recognize a specific drop-off point and signal to the hand to release its cargo.

Each of these components is made of just a few nucleotides within a single strand of DNA.

In principle, these modular building blocks could be assembled in many different ways to complete different tasks.

For example, a DNA robot with several hands and arms, could be used to carry multiple molecules simultaneously.

In the work described in the Science paper, the Qian group built a robot that could explore a molecular surface, pick up two different molecules and then distribute them to two distinct regions on the surface.

"The DNA robot moves around on a 58-nanometer-by-58-nanometer pegboard on which the pegs are made of single strands of DNA complementary to the robot's leg and foot vans old skool blanche femme ," Qian's team said in a statement.

"The robot binds to a peg with its leg and one of its feet -- the other foot floats freely," the team said.

"When random molecular fluctuations cause this free foot to encounter a nearby peg, it pulls the robot to the new peg and its other foot is freed. This process continues with the robot moving in a random direction at each step."

Since one step for the little guy takes five minutes, and allows it to move six nanometers, it may take a day for the robot to explore the entire board, the team said.

"Along the way, as the robot encounters cargo molecules tethered to pegs vans old skool blanche , it grabs them with its 'hand' components and carries them around until it detects the signal of the drop-off point," it said.

"The process is slow, but it allows for a very simple robot design that utilizes very little chemical energy."

In a summary on the robot, the Science magazine called Qian's work "one small step for a DNA robot, one giant leap for mankind.

"The future is here," the summary wrote.

LONDON, May 26 (Xinhua) -- British Deputy Prime Minister and leader of the pro-European Liberal Democrats Nick Clegg said Monday his party suffered a "huge setback" in the European elections vans old skool noir femme pas cher , as the Eurosceptic UK Independence Party (UKIP) has wiped out most of its seats in the European legislature.

By Monday afternoon, UKIP has won 27.5 percent of the votes and prevailed over all the other political parties by increasing its Members of European Parliament (MEPs) seats from 13 to 24, beating the traditional mainstream parties for the first time in a national election.

The Liberal Democrats, which formed a coalition government with Prime Minister David Cameron's Conservative Party in 2010, has seen its vote share halved to a mere 6.9 percent and lost all but one of its 11 seats announced so far in the European legislature.

The Liberal Democrats is seen as the most pro-European mainstream political party in Britain, and Clegg joined two face-to-face debates with UKIP leader Nigel Farage earlier this year to defend Britain's European Union (EU) membership.

It is "gutting" and "heartbreaking" to see Liberal Democrats candidates, councilors and MEPs lose their seats vans old skool noir femme , said Clegg, a vocal advocate for British integration into Europe, on British national TV.

He said there has been a very sharp turn to the right, in some cases the far-right, not only in Britain but also across Europe.

Following the electoral defeat, Clegg has been under mounting pressure to step down as the party leader, but the deputy prime minister said he will not "walk away."

The Liberal Democrats vans old skool noir , a social-liberal political party in Britain, was established in 1988 by the merger of the Liberal Party and the Social Democratic Party.

In 2010, it became the third-largest party in Britain's House of Commons after winning 57 seats with 23 percent of the votes in the general elections that year.

The Liberal Democrats joined a coalition government with the Conservatives, with Clegg becoming Deputy Prime Minister.

Following a string of victories in European and local elections, Farage said Monday that UKIP has become the third political force in Britain and aspired to have its first batch of members of the British Parliament next year.

"This party has done something that hasn't been done for over a hundred years: We have won a national election in this country, and I am immensely pound of that achievement," Farage said in his victory speech on Monday.

"It is an earthquake in British politics vans old skool gris et noir , it is a remarkable result, and it does have profound consequences for the leaders of the other parties," he added.

On Friday, Farage said his party will become a "serious player" in Britain's 2015 general elections, aiming to bring the country into an era of "four-party politics".

The Labor Party and the Conservatives, the two major parties that have dominated British politics in the past century, won 25.4 percent and 23.9 percent of the votes respectively vans old skool gris , coming second and third with 20 and 19 seats.
