研究揭示精神分裂症新遗传基础
精神分裂症 新遗传基础 全基因组
2014/7/23
在至今为止进行的最大规模的精神分裂症全基因组关联分析中，科学家发现了超过100个和精神分裂症有关的基因变异，这可能为确定新治疗靶点铺就了道路。发表在本周《自然》杂志上的这项研究，在为人们提供关于该疾病新见解的同时，也支持了其发展和免疫系统的相关理论。在此之前，科学家只发现了和此疾病易感性相关的30个基因位点。

合成酵母染色体 全功能染色体
2014/3/31
美国遗传学家Craig Venter曾耗资4000万美元、历时15年合成了一个细菌寄生虫基因组。而3月27日，一个主要由大学生组成的研究团队报告了生物合成学领域的一次重大飞跃：源自酿酒酵母的一种重新设计并合成的全功能染色体。这一成果被誉为攀上了合成生物学的新高峰，也是向合成人造微生物等生命体迈出的一大步。
UNIVERSITY PARK, Pa. -- DNA can already tell us the sex and ancestry of unknown individuals, but now an international team of researchers is beginning to connect genetics with facial features, degrees...
