A two-publisher model for the scientific article: narrative+shared data.

I do go on rather a lot about enabling or hyper-activating[1] data. So do others[2]. Why is sharing data important?

Can a cyclobutadiene and carbon dioxide co-exist in a calixarene cavity?

On 8th August this year, I posted on a fascinating article that had just appeared in Science[1] in which the crystal structure was reported of two small molecules, 1,3-dimethyl cyclobutadiene and carbon dioxide, entrapped together inside a calixarene cavity. Other journals (e.g. Nature Chemistry[2] ran the article as a research highlight (where the purpose is not a critical analysis but more of an alerting service). A colleague, David Scheschkewitz, pointed me to the article. We both independently analyzed different aspects, and first David, and then I then submitted separate articles for publication describing what we had found. Science today published both David’s thoughts[3] and also those of another independent group, Igor Alabugin and colleagues[4]. The original authors have in turn responded [5]. My own article on the topic will appear very shortly[6]. You can see quite a hornet’s nest has been stirred up!
