Nerval's Lobster writes "Research scientists could learn an important thing or two from computer scientists, according to a new study (abstract) showing that data underpinning even groundbreaking research tends to disappear over time. Researchers also disappear, though more slowly and only in terms of the email addresses and the other public contact methods that other scientists would normally use to contact them. Almost all the data supporting studies published during the past two years is still available, as are at least some of the researchers, according to a study published Dec. 19 in the journal Current Biology. The odds that supporting data is still available for studies published between 2 years and 22 years ago drops 17 percent every year after the first two. The odds of finding a working email address for the first, last or corresponding author of a paper also dropped 7 percent per year, according to the study, which examined the state of data from 516 studies between 2 years and 22 years old. Having data available from an original study is critical for other scientists wanting to confirm, replicate or build on previous research – goals that are core parts of the evolutionary, usually self-correcting dynamic of the scientific method on which nearly all modern research is based. No matter how invested in their own work, scientists appear to be 'poor stewards' of their own work, the study concluded."
