    11-02-24 Understanding the genetics of bipolar disorder(躁郁症) could lead to new treatments, but identifying specific genetic variations associated with this disorder has been challenging. A new study in Biological Psychiatry implicates a brain protein ca...

  • 普通蛋白质可以与阳光反应获取能量

    11-01-27 Professor Richard Watt and his chemistry students suspected that a common protein could potentially react with sunlight and harvest its energy similar to what chlorophyll(叶绿素) does during photosynthesis(光合作用) . The story of how they prove...

  • 科学家揭示艾滋病毒外壳完整结构

    11-01-20 A team of scientists at The Scripps Research Institute and the University of Virginia has determined the structure of the protein package that delivers the genetic material of the human immunodeficiency virus (HIV) to human cells. The work is the cu...

  • 麻疹病毒蛋白的活动方式

    11-01-10 Mayo Clinic researchers have shown that proteins on the surface of a cell twist a viral protein(病毒蛋白) into position, allowing the virus to start infection and cause disease, all in a movement as graceful as a ballroom dance. The findings appea...
