I'm a big fan of the work Nature publishing group is doing in experimenting with new methods of publishing, such as their iOS apps (which inspired me to "clone" their iPhone app) and the Encode app with the concept of "threads". But there's an aspect of the iPad app that puzzles me: Nature's app doesn't know that a linked article elsewhere in Nature is also available using the app.

tl;dr Readmill might be a great platform for shared annotation and correction of Biodiversity Heritage Library content.Thinking about accessing the taxonomic literature I started revisiting previous ideas.

Prompted by a conversation with Vince Smith at the recent Online Taxonomy meeting at the Linnean Society in London I've been revisiting touch-based displays of large trees. There are a couple of really impressive examples of what can be done. Perceptive Pixel I've blogged about this before, but came across another video that better captures the excitement of touch-based navigation of a taxonomy.

The release of the ENCODE (ENCyclopedia Of DNA Element) project has generated much discussion (see Fighting about ENCODE and junk). Perhaps perversely, I'm more interested in the way Nature has packaged the information than the debate about how much of our DNA is "junk." Nature has a website (http://www.nature.com/encode/) that demonstrates the use of "threads" to navigate through a set of papers.

organic chemistry. It does not look like much, but this small little molecule brought us ferrocene, fluxional NMR, aromatic anions and valley-ridge inflexion points. You might not have heard of this last one, but in fact I mentioned the phenomenon in my post on nitrosobenzene. As for being at a crossroads, more like a Y-junction. Let me explain why.

A month or so ago at a workshop I was attending, a speaker included in his introductory slide a QR (Quick Response) Code. It is a feature of most digital eco-systems that there is probably already “an app for it”. So I thought I would jump on the band wagon by coding an InChI string. Here it is below: QRCode for an InChI string. Point your smart device at it, and see the InChI appear!

As part of a course on "phyloinformatics" that I'm about to teach I've been making some visualisations of classifications. Here's one I've put together using jQuery Mobile and the Encyclopedia of Life API. It's pretty limited, but is a simple way to explore EOL using three different classifications.

One of the things I keep revisiting is the way we display scientific articles. Apart from Nature's excellent iPhone and iPad apps, most efforts to re-imagine how we display articles are little more than glorified PDF viewers (e.g., the PLoS iPad app).Part of the challenge is that if we make the article more interactive we immediately confront the problem of how to link to other content.

Most representational chemistry generated on a computer requires the viewer to achieve a remarkably subtle transformation in their mind from two to three dimensions (we are not quite yet in the era of the 3D iPad!). The Cahn-Ingold-Prelog convention was a masterwork (which won the Nobel prize). It is shown in action for the molecule on the left below.

Since I won't be able to be at the Biodiversity Heritage Library's Life and Literature meeting I thought I'd share some ideas for their Life and Literature Code Challenge. The deadline is pretty close (October 17) so having ideas now isn't terribly helpful I admit. That aside, here are some thoughts inspired by the challenge.
