This week we discuss how published nucleotide sequences are not always correct or to be trusted with Yasunori Park and Professor Jennifer A Byrne (@JAByrneSci), a research Assistant and PI at the University of Sydney (@Sydney_uni). We delve into the details of their nifty new text mining tool (Blast and Seek) which highlights papers with incorrect nucleotide sequences. We also discuss the most common mistakes found, the impact of these mistakes, and what we can do as researchers to prevent errors from occurring. We also talk about prepints and Australian Research Council’s recent decision to ban preprints in their grant applications as well as some insight into our very own PhD’s.
