Here's a heads up that the Stanford-developed mobile app for viewing the secondary structure of RNA molecules is available for download.
Titled iPARS (link to ITunes store), the app is free and allows scientists to enter a specific RNA from baker's yeast into their iPhone or iPad and see a depiction of its two-dimensional structure.
The technology behind the app makes it possible, for the first time, to experimentally capture a global snapshot of the conformation of thousands of RNA molecules in a cell. Previously, the only way to know what shape a particular RNA molecule preferred was to conduct a laborious series of experiments focused on just that molecule.
