Oops. In my note about the launch of Nature Precedings last week, I said incorrectly there were 64 submissions on the launch date and gave the breakdown by subject category.
This made a rather elementary error – my numbers assumed that each submission was in only one subject category, whereas course many have multiple categories.
Looking at the site a week later, there appear to be 43 submissions, split roughly 40:60 between manuscripts (17) and poster/presentations (26).
Bioinformatics is still by far the most popular single category, though.
