数据是科学研究的命脉。但所有曾被细致记录下来的发现，或许都已危在旦夕。一项研究表明，研究数据正在以惊人的速度消失不见，相关数据发表于《当代生物学》（Current Biology）杂志。科学研究通常建立在已经获得的研究结果之上，科学家会引用先前研究中的事实与数据，来支持自己的分析或证实先前的结果仍然成立。但他们是否每次都能找到自己需要的原始数据呢？为了找出结果，研究人员选择了500项发表于1991-2011年间的研究成果，并向作者索取研究的原始数据。在文章发表20年后，80%的数据已无处可寻……[查看全文]
Where Have All the Data Gone?
Data are the lifeblood of science. But all those carefully recorded observations may be in danger. Because a new study shows that data from the recent past are being lost at an alarming rate. The journal Current Biology has the data to prove it.Scientific studies build on research that came before. And scientists turn to the facts and figures from previous work to aid in their own analyses or confirm that the earlier results still hold up. But how often can they access the older data they need?To find out, researchers selected 500 studies published between 1991 and 2011. And they sent the authors a request for the studies’ raw data. Twenty years after publication, 80 percent of the data was unavailable...[full transcript]
