根据理论，金属氢可能是一种超导体，能显著提升电子设备性能，与此同时，还有可能为能源、医疗、交通运输等行业带来巨大变革。然而不久之后，哈佛大学再次发布声明，由于操作失误，这块金属氢样本消失了……消失了……
当时，他们正在用激光测量这块唯一的金属氢样本，用来制造样本的金刚石由于巨大压力突然粉碎，导致金属氢掉落消失。
根据推测，金属氢可能是化作气态升华，也有可能掉落和其他东西混在一起，也有人怀疑，该团队从未制作出金属氢，而样本的消失导致“死无对证”……
打破疑虑的方法只有一个，再造一块金属氢。

“一滴血筛查 12 种癌症，检测过程仅需 5 至 10 分钟费用不到 100 元”！

目前，团队已不再接受采访，校方表示网上现有报道并不完全准确。
近年来“滴血验癌”消息层出不穷，原理无非是检验血液中的“肿瘤标志物”，然而权威的医学指南并不用肿瘤标志物来筛查癌症。

撤稿，对很多科研人员来说是非常尴尬的一件事情。这不仅意味着对其学术水平的否定，还意味着学术生涯上的不良记录。
今年有两起华人论文撤稿事件受到了整个学界的关注：
一是韩春雨团队历经 15 个月，终于撤回稿件。
早些时候，韩春雨等人在权威期刊上发表论文并因此获得大量喝彩，但重复实验均无法得到相同结果，人们开始质疑韩春雨论文的可信度，事情最终以撤稿收尾，但对华人学术界的影响却久久无法平息。
另一个重大撤稿事件利用了“同行评审制度”中的技术漏洞，使用假邮箱，冒充评审人对论文给出评审意见，是一种虚假的同行评审。
因为这个原因，著名学术出版商施普林格，在今年一次性撤稿了 107 篇论文！而这被撤的 107 篇论文全部来自中国，也有涉事国内研究人员声称，是委托代理机构在投稿时弄虚作假。对此，施普林格表示会开发相关工具，防范类似情况再次发生。
这两起撤稿事件，不免让人为华人学界的科研诚信打上了一个问号。
