新技术引发伦理争议

<正>2014年10月,英国政府要求生育管理机构,对来自中国的新生婴儿进行研究调查。该研究采用了一种微创形式的试管婴儿技术,能降低新生儿出生缺陷的风险。英国人类受精和胚胎管理局(HFEA)称,其中采用的技术"很有前景",而且与现有技术相比     

Complete Nucleotide Strain Sequence of a Newly Avirulent Newcastle Disease Virus Hubei 92（HB92） Strain

A new avirulent, heat-resistance HB92 strain of newcastle Disease Virus (NDV) was acquired from Australia V4 strain. Its complete nucleotides sequence was first determined. The entire genome of NDV HB92 consists of 15 186 nucleotides (GenBank accession no. AY225110). It was demonstrated by sequence analysis that nucleotides homology of HB92 strain with virulent strain ZJ1 were 83.9%, and the homology compared with avirulent vaccine strain La Sota and B1 were 94. 0% and 93. 5%, respectively. These results might be contributive to the study of the molecular mechanism of evolution of the NDV strain HB92 and to develop the engineered recombinant vaccine.     

孩子的智商由谁决定

<正>研究人员统计了美国两千多个家庭的父母及孩子的智商数据发现,母亲和孩子之间的智商确实比父亲和孩子的相关性略强比如,母亲和儿子的智商相关程度为0.443(相关性越接近1,两者相关性越强),而父亲和儿子的则为0.411。但是,这种微乎其微差距说明"儿子的智商由妈妈决定
