Platform: iPad  
Cost: Free

For mathematically inclined researchers (or students who wants a hands-on way to familiarize themselves with the Hodgkin-Huxley equation or Hidden Markov Models), XPP is a fantastic and free virtual playground! Incredibly vast in its computing capabilities, this app will solve differential equations, run simulations such as those mentioned above, solve boundary value problems, and more. The XPP app uses plain text files called ODE files, some examples of which are preloaded in the app, and thousands more of which are available from the internet or via iTunes import. Conveniently, the “help” section of the app is quite comprehensive and includes a section to familiarize users with the ODE syntax. Users can create and edit their own code within the app.

Scientifically Studying Ecstasy

MDMA (commonly known as the empathogen “ecstasy”) is classified as a Schedule 1 drug, which is reserved for compounds with no accepted medical use and a high abuse potential. Two researchers from Stanford, however, call for a rigorous scientific exploration of MDMA's effects to identify precisely how the drug works, the data from which could be used to develop therapeutic compounds.

Do you agree that ecstasy should be studied for its potential therapeutic benefits?
