生物通报道：英国著名杂志《Nature》是世界上最早的国际性科技期刊之一，自从1869年创刊以来，始终如一地报道和评论着全球科技领域里最重要的突破，是研究人员了解和掌握本领域研究动态的一种重要手段。

近期《Nature》网站推出了《Nature China》子刊栏目，主要目的就是将中国大陆以及香港地区的优秀研究成果介绍给全球的科学家们，并提供一个更好更方便的了解窗口。目前这一网站（http://www.nature.com/nchina/index.html）以beta form的形式提供了自2000年起的《Nature》杂志，以及其它顶级科学刊物中出版的中国科学家的一些优秀研究成果的简短评述摘要，另外对于《Nature》杂志，这里也提供了全文的查询途径。

目前这一网站每隔一个星期就会挑选近期出版的优秀研究成果，以摘要的形式刊登出来，读者可以推荐一些文章进行投票，其中最好的将会被选入《Nature China》。
