韩春雨团队撤回论文 河北科大启动学术评议及相关程序

围绕河北科技大学韩春雨团队有关一种新基因编辑技术论文的争议持续一年多之后,发表这篇论文的英国《自然·生物技术》杂志2日在其网站上刊登韩春雨等人的声明说,由于科研界一直无法根据他们论文提供的实验方案重复出其展示的关键结果,“我们决定撤回这项研究”。

昨天,河北科技大学决定启动对韩春雨该项研究成果的学术评议及相关程序。

综合 新华社 《法制晚报》

韩春雨团队去年5月在全球著名学术刊物《自然·生物技术》上报告说,他们发明了一种新的基因编辑技术NgAgo-gDNA。根据论文,与当前基因编辑领域内的主流技术CRISPR-Cas9“基因剪刀”技术相比,NgAgo-gDNA技术在一些方面具有优势。但随后中国及其他国家有学者公开表示,无法重复论文中描述的实验,这项研究成果遭到多方质疑。

韩春雨团队2日在撤稿声明中说,虽然许多实验室都进行了努力,但是没有独立重复出这些结果的报告。“因此,我们现在撤回我们的最初报告,以维护科学记录的完整性”。

与此同时,《自然·生物技术》杂志在一篇题为《是该数据说话的时候了》的社论中说,“如今尘埃落定,这也是世界各地的许多实验室为澄清NgAgo的功能而付出的大量时间、精力和资金的证明”,“我们现在确信韩春雨的撤稿决定是维护已发表科研记录完整性的最好做法”。

8月3日,韩春雨团队发布了声明。声明表示,韩春雨团队同意按学校安排选择一家第三方实验室,在同行专家支持下开展实验,验证NgAgo-gDNA基因编辑的有效性,并将实验结果公布,以回应社会关切。

昨天上午,河北科技大学在官网刊发《韩春雨团队发布声明》,指出“鉴于该论文已撤稿,学校决定启动对韩春雨该项研究成果的学术评议及相关程序”。

撤稿是否等同于学术造假?

按国际惯例,研究团队发表的文章结论必须是可重复的。“主动撤稿表明韩春雨团队意识到有不能重复的问题。”美国梅奥医学中心教授楼振昆说,“能够主动撤稿需要勇气。现在还没有证据可以证明韩春雨团队是造假。希望韩春雨团队能够公布实验原始资料和数据,研究人员可以根据实验记录一步步重复,看是否能够重复出来。
