BERLIN Under Armour Running Shoess Sale , July 31 (Xinhua) -- The majority of Germans are in favor of targeted bans on diesel vehicles in areas affected by nitrogen oxide pollution, a poll cited by media reports on Monday has found.


According to the survey conducted by Emnid for the non-governmental environmental organization Greenpeace, 57 percent of respondents agreed that diesel vehicles should no longer be able to access urban areas with poor air quality. 39 percent of respondents rejected such bans.


The findings were surprising in light of the high market share still enjoyed by diesel cars in Germany. Despite falling in the wake of the "dieselgate" scandal and the related threat of bans and losses in resale value, diesel cars still accounted for 40 percent of newly registered vehicles in Germany in May.


Support for driving bans was notably higher among women (63 percent) than among men (51 percent).


Additionally Under Armour Mens Shoess Sale , 86 percent of respondents demanded that producers recall and upgrade vehicles to ensure that they meet relevant emission regulations in daily use.


"A little bit of software-cosmetics alone cannot protect the people's health," Niklas Schinerl, energy expert at Greenpeace, told the newspaper Rheinische Post.


"The producers must improve their hardware as well. " Schinerl argued. He described the "continued inactivity" of Federal Transport Minister Alexander Dobrindt (CSU) as "bordering on failure to render assistance."


On Wednesday Under Armour Womens Shoess Sale , German government representatives will meet with the country's automotive industry for a "diesel summit" during which they will discuss means to lower urban nitrogen oxide pollution.


Older diesel-powered vehicles are responsible for the bulk of nitrogen oxide pollution in urban areas.


According to the newsmagazine SPIEGEL, plans to meet this objective will center on software upgrades for diesel motors in the European Union's Euro-5 and Euro-6 regulatory emissions categories.


Ahead of the summit, environmental activist groups including Greenpeace have held protests in front of the offices of the Federal Transport Ministry.

CHICAGO, July 26 (Xinhua) -- Researchers at the University of Chicago (UChicago) have found for the first time that a key protein complex in the brain is linked to the ability of young animals to learn behavioral patterns from adults.


A specific neural signal Under Armour Shoes Sale , the mechanistic Target of Rapamycin (mTOR) cascade, regulates the ability of juvenile zebra finches to form accurate memories of songs taught to them by adult birds, the research finds.


This suggests mTOR's function in regulating protein synthesis may be involved, since protein synthesis is known to be a key feature of long-term memory formation.


The results have potentially provided new insight into children affect by neurodevelopmental disorders Under Armour Boys Shoes , as disruptions related to mTOR have been associated with autism spectrum disorders in humans.


"In the last five to 10 years, there seems to be a convergence on the mTOR cascade as a common disrupted process in autism spectrum disorders. We are not investigating autism per se, but what got our attention was that the zebra finches model a similar kind of situation," said Sarah London Under Armour Kids Shoes , assistant professor in the Department of Psychology of UChicago.


For the study, the researchers first confirmed the mTOR cascade was present in the brain of a juvenile zebra finch, and then established the cascade was activated in the auditory forebrain when a bird heard a song. They found that temporarily pharmacologically inhibiting or enhancing mTOR activation in the auditory forebrain directly diminished the ability of the bird to copy song from an adult tutor.


When molecular signaling in the auditory forebrain was disrupted during daily encounters with adult tutors, young zebra finches produced shorter and less complex songs that no longer reflected the tutor's song. Using software specifically designed for vocal comparison Under Armour Running Shoes , the researchers analyzed the song patterns of the adults and the juvenile males with whom they interacted. The juvenile birds whose mTOR activation was modified by drug infusions retained the ability to sing and to mimic acoustic elements of the tutor's songs, but were unable to duplicate entire song structures.


"We had evidence from other lab studies that mTOR inhibition disrupted learning events, and we had evidence that its activation did also, " London said.


In addition to measuring the effects on song copying Under Armour Mens Shoes , the researchers also determined how mTOR activation influenced social engagement. During birds' song interaction with tutors, they recorded the position of the young birds in and out of a "hot zone" near the tutor's perch. Birds who had pharmacologically elevated levels of mTOR activation demonstrated less engagement with the adults. This is similar to what has been observed in children diagnosed with autism spectrum disorders, who often have mutations predicted to increase levels of mTOR signaling.


The finding presents a new opportunity to understand mechanisms by which social interactions enhance vocal learning ability of zebra finches and children, London believes.


The research finding by UChicago has been published in the Proceedings of the National Academy of Sciences on July 24.
