Stata Center. MIT Originally uploaded by Roderic Page Quick post about the Elsevier Challenge, which took place yesterday in the wonderful Stata Center at MIT. It was a great experience.

I'm in the US on UK time, so this is probably a bad idea to write this, but the paper by Malte Ebach et al. ("O Cladistics, Where Art Thou?", doi:10.1111/j.1096-0031.2008.00225.x) in the latest Cladistics just annoys me too much.

The latest post on the EOL blog (Biodiversity in a rapidly changing world) really, really annoys me. It claims that Nope, I suggest it demonstrates just how limited EOL is. If I view the page for the red lionfish I get an out of date map from GBIF that shows a very limited distribution, and doesn't show the introductions in Florida and the Bahamas (I have to wade through text to find reference to the Florida introduction, and the page doesn't

The Science Commons has released a short video by Jesse Dylan, who made the Yes We Can video.

Quick note to say how much I like the programmers' Q & A site Stack Overflow. I've only asked two questions, but the responses have been rapid and useful. I found out about Stack Overflow by listening to the Stack Overflow podcast episodes on IT Conversations (which carry a lot of other podcasts as well). For a wannabe geek, these podcasts are a great source of ideas.

Among the many weaknesses of my challenge demo is the way it simply dumps out a list of sequences (see comments on the demo.

I've submitted my entry for the Elsevier Grand Challenge. The paper describing the entry is available from Nature Precedings (doi:10.1038/npre.2008.2579.1). The web site demo is at http://iphylo.org/~rpage/challenge/www/. I'm now officially knackered.

One byproduct of playing with the Challenge Demo is that I come across some rather surprising results.

I've put the my Elsevier Challenge demo online. I'm still loading data into it, so it will grow over the next day or so. There's also the small matter of writing a paper on what's under the hood of the demo. Feel free to leave comments on the demo home page. For some example of what the project does, take a look at Mitochondrial paraphyly in a polymorphic poison frog species (Dendrobatidae;

One of the things I've struggled with most in putting together a web site for the challenge is how to summarise that taxonomic content of a study. Initially I was playing with showing a subtree of the NCBI taxonomy, highlighting the taxa in the study. But this assumes the user is familiar with the scientific names of most of life. I really wanted something that tells you "at a glance" what the study is about.

Elsevier have released this video about the challenge, featuring a few of the contestants. I couldn't get my act together in time to send anything useful, and having seen the 16 gigabytes song (full version here), I'm glad I didn't -- there's just no way I could compete with Michael Greenacre and Trevor Hastie.
