Symbiosis between computation and experiment is increasingly evident in pedagogic journals such as J. Chemical Education. Thus an example of original laboratory experiments[1],[2] that later became twinned with a computational counterpart.[3] So when I spotted this recent lab experiment[4] I felt another twinning approaching.

Most of the chemical structure diagrams in this blog originate from Chemdraw, which seems to have been around since the dawn of personal computers! I have tended to use this program to produce JPG bitmaps for the blog, writing them out in 4x magnification, so that they can be scaled down for display whilst retaining some measure of higher resolution if needed for other purposes. These other purposes might be for e.g. the production of e-books (using Calibre), the interesting Blog(e)book format offered as a service by Feedfabrik, or display on mobile tablets where the touch-zoom metaphor to magnify works particularly well. But bitmap images are not really well future proofed for such new uses. Here I explore one solution to this issue.

I have for perhaps the last 25 years been urging publishers to recognise how science publishing could and should change. My latest thoughts are published in an article entitled “The past, present and future of Scientific discourse” (DOI: 10.1186/1758-2946-3-46). Here I take two articles, one published 58 years ago and one published last year, and attempt to reinvent some aspects. You can see the result for yourself (since this journal is laudably open access, and you will not need a subscription). The article is part of a special issue, arising from a one day symposium held in January 2011 entitled “Visions of a Semantic Molecular Future” in celebration of Peter Murray-Rust’s contributions over that period (go read all 15 articles on that theme in fact!).
