Here is an interesting development that might be of interest to all bioinformaticians. Two radically different genomes have been assembled for the tardigrade. The authors of the the second paper believe that the results of the first are solely due to contamination.
A bioinformatician's worst nightmare is to wake up and realize that in that in a published analysis of yours something went awfully wrong. It could happen to us all.
