Kangaroos walk on their tail


SYDNEY nike cortez rosa , July 2 (Xinhua)-- Kangaroos use their tail as an extra leg when they walk, according to new Australian research revealed Wednesday.


The study found that the animals use their tail more than their forelimbs when they walk, the Australian Broadcast Association ( ABC) reported.


The findings provide new insights into kangaroo locomotion nike cortez bianche uomo , and could also have applications in advanced robotics.


Professor Terry Dawson of the University of New South Wales and colleagues found that kangaroos walk by using the tail to lift both hind legs and the body's centre of gravity forward, while the forelimbs were used as struts and didn't provide any of the propulsion.


Tests showed there was far more propulsion energy provided by the tail than scientists had thought.


Dawson said the team is interested in mechanical analogues to walking and locomotion.


"There's interest in the robotic side of things and how other forms of locomotion can work," said Dawson.


"You can locomote just using your legs nike cortez bianche e nere , but there are other options for stability and it's interesting from that point of view. "




WASHINGTON, Sept. 27 (Xinhua) -- U.S. President Barack Obama on Tuesday nominated Jeffrey DeLaurentis as the first U.S. Ambassador to Cuba in over 50 years.


"Today, I am proud to nominate Ambassador Jeffrey DeLaurentis to be the first U.S. Ambassador to Cuba in more than 50 years," Obama said in a news release issued by the White House.


Obama praised DeLaurentis' vital "leadership" throughout the normalization of relations between the U.S. and Cuba, which were two former rivals.


"There is no public servant better suited to improve our ability to engage the Cuban people and advance U.S. interests in Cuba than Jeff," Obama said.


The president described DeLaurentis, a career diplomat, as having "extensive experience in Cuba and Latin America."


DeLaurentis has been working with Cuba on issues that advance U.S. national interests, such as law enforcement, counternarcotics, environmental protection, combating trafficking in persons, expanding commercial and agricultural opportunities, and cooperation in science and health, Obama said.


"Having an ambassador will make it easier to advocate for our interests, and will deepen our understanding even when we know that we will continue to have differences with the Cuban government," Obama said.


The U.S. and Cuba resumed diplomatic relations in July 2015, ending more than five decades of hostilities. Obama paid a historical visit to Cuba in March in the first such visit by a sitting U.S. president in nearly 90 years.


DeLaurentis has been the Chief of Mission at the U.S. Embassy in Havana, Cuba, since 2015 after serving as Chief of Mission at the U.S. Interests Section in Havana from 2014 to 2015.


Prior to that, he served as Ambassador and Alternate Representative for Special Political Affairs at the U.S. Mission to the United Nations from 2011 to 2014. Before that, he was Deputy Assistant Secretary of State for the Bureau of Western Hemisphere Affairs.


Since beginning his State Department career in 1991, DeLaurentis has served in a number of overseas posts, including twice before in Havana, first as consular officer from 1991 to 1993, then as Political-Economic Section Chief from 1999 to 2002.


He also served as political counselors at the U.S. Mission to the UN in Geneva, and the U.S. Embassy in Bogota, Colombia.


WASHINGTON, Feb. 11 (Xinhua) -- In her first testimony to the Congress, U.S. Federal Reserve Chair Janet Yellen reiterated central bank's plan to taper its stimulus exit despite recent weakness in the economy.


The current economic situation and outlook nike cortez bianche , as well as the monetary policy, were the main focus of the hearing held twice a year.


Yellen told lawmakers she expected "a great deal of continuity" in the central bank's monetary policy, saying that she served on the Fed policy-setting committee as the bank formulated its current policy strategy and she strongly supported that strategy.


Yellen nike cortez blu e gialle , 67, took the oath of office to lead the Federal Reserve System on Feb. 3, succeeding Ben Bernanke nike cortez blu uomo , who stepped down after eight turbulent years. She was previously the Fed's vice Chair.


In the public debut in her new role, Yellen said while the economy gained steam at the end of 2013, recovery in the U.S. labor market was "far from complete nike cortez blu ," underscoring the importance of considering more than just the unemployment rate when evaluating the conditions of the labor market.


Her point of keeping an eye on wider range of labor indicators is particularly important as the unemployment rate, now at 6.6 percent, is near the 6.5 percent threshold the Fed once identified as the level that would need to be reached before officials would consider a hike in the interest rates.


"If coming information broadly supports the Committee's expectation of ongoing improvement in labor market conditions and inflation moving back toward its long-run objective nike cortez nere pelle , the Committee will likely reduce the pace of asset purchases in further measured steps at future meetings," Yellen indicated steady pullback in Fed stimulus, referring to the Federal Open Market Committee nike cortez nere uomo , which sets monetary policy.


While admitting she was "surprised" by the two recent jobs reports that showed the pace of job creation running under what she had expected, Yellen cautioned against jumping to conclusions of the longer trend. She told the Congress that the Fed needs to see a "notable change" in the economic outlook to consider pausing its withdrawal of stimulus.


The Fed trimmed its monthly purchases of Treasury and mortgage- backed securities by a total of 10 billion dollars in both December and January, citing strengthening economy and continued improvement in the labor market.


The Fed policymakers have sugges.
