April 4, 2011 (LifeSiteNews.com) – Researchers at the University of
Minnesota used adult stem cells to create a living human heart that they
hope will revolutionize transplants.
The breakthrough, said lead researcher Dr. Doris Taylor, could ultimately

本文在简要回顾中国科学史的基础上,介绍一些近年研究的内容,肯定中国
科学令人乐观的进步,并讨论可能的意义。同时也指出,中国优秀论文总量仍不
到世界的百分之一,低于中国经济在世界所占的百分比、也不能适应中国持续发
展的要求。中国科学的规模需要相当程度的扩大、质量有待进一步提高。中国科

要从生命科学的研究来讨论中国科学的情况,一方面这是我有一定判断力的领域,
另一方面生命科学是科学技术最重要的组成部分之一,可以反映科学主流。讨论
中国论文发表情况前,先谈两个背景:中国科学的历史情况,优秀科学和著名杂
志的关系。
奠定中国生命科学研究是二、三十年代协和医学院生理系林可胜和生化系吴

GPS,使得我们能在空间中定位自己身在何处,这表明这种高级认知功能也有细胞
级别的基础。
1971年,约翰·奥基夫发现了这个定位系统的第一个成分。他发现,大脑海马体里
有一种神经细胞,每当大鼠身处屋子的某个特定地点的时候,这种细胞总是会被激
活。其它神经细胞则在大鼠身处其它地方的时候被激活。奥基夫的结论是,这些“
位置细胞”(place cells)组成了屋子的地图。
三十多年后,迈-布里特·莫泽和爱德华·莫泽发现了大脑定位系统的另一个关键
成分。他们发现了另一种神经细胞,命名为“网格细胞”(grid cells),它们组
成了一个坐标系,允许生物进行精确的定位和寻路。他们的后续研究表明,地点细
