As they shared common interests in traditional crafts of lacquer art, they started their own studio and store in Beijing, demonstrating art works they created and objects they collected. They want to make the lacquer art more recognized in people's daily life. (XinhuaWeng Xinyang)

     

    CHICAGO Nike Air Max Womens Clearance , 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, 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 Nike Air Max Womens Sale , 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, as disruptions related to mTOR have been associated with autism spectrum disorders in humans.

     

    "In the last five to 10 years Nike Air Max Womens Shoes , 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 Nike Air Max Womens , 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 Cheap Air Max Womens , young zebra finches produced shorter and less complex songs that no longer reflected the tutor's song. Using software specifically designed for vocal comparison, 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 Air Max Womens Black , and we had evidence that its activation did also, " London said.

     

    In addition to measuring the effects on song copying, the researchers also determined how mTOR activation influenced social engagement. During birds' song interaction with tutors Air Max Womens Clearance , 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.

     

     

     

    YANGON Air Max Womens Sale , April 15 (Xinhua) -- Myanmar's Yangon regional government had entered a contract with Chinese Yutong company for buying over 1,000 buses to supply Yangon Bus Services System, official media reported Saturday.

     

    The buses will arrive next month and run on Yangon Bus line Air Max Womens Shoes , an official of Yangon Region Transport Authority was quoted as saying.

     

    Yangon Region Chief Minister U Phyo Min Thein vowed that Yangon bus services system will be upgraded to meet international standard early next year.

     

    All 300 old bus lines running in Myanmar's former capital city of Yangon were abolished and replaced with up to the 79 new bus lines starting on Jan. 16 in an effort to reduce traffic jam in the city and make the bus lines systematically operational.

     

    According to the Yangon regional office, there are currently 79 bus lines operated by 3,500 buses in Yangon to transport 2.5 million people daily out of 6 million's residents in Yangon.

     

     

     

    LONDON, March 8 (Xinhua) -- Historic England and the Royal Society marked International Women's Day on Wednesday by celebrating 28 groundbreaking women in science.

     

    Despite the impact they made in their lives, few had been in the spotlight, unlike many of their male contemporaries who are often celebrated with public statues and memorials.

     

    Historic England and the Royal Society have recorded the contributions female scientists in Britain have made to the world.

     

    Historic England also announced Wednesday that the tomb in London of celebrated biologist Rosalind Franklin was to be listed as an official national monument.

     

    Franklin died aged just 37, but her pioneering X-ray observation of DNA helped lay the foundation for molecular biology. It contributed in 1953 to the discovery of the helical structure by scientists Crick and Watson.

     

    The 28 women listed each personally championed ground-breaking work in chemistry, biology, science and astronomy from past generations.

     

    Parliamentary Under Secretary of State for Sport, Tourism and Heritage, Tracey Crouch, said: "The important role women have played in the field of British science is too often forgotten. .
