Something different for you to try:

Basically create RNA structures through a series of very addictive challenges. They add new ones ever week and you could have one of your designs tested in the lab and who knows you could be responsible for the next big medical breakthough.
I have created a WeChall group - so try it out and lets show that We are the elite Challengers ;-)
About eteRNA
By playing EteRNA, you will participate in creating the first large-scale library of synthetic RNA designs. Your efforts will help reveal new principles for designing RNA-based switches and nanomachines -- new systems for seeking and eventually controlling living cells and disease-causing viruses. By interacting with thousands of players and learning from real experimental feedback, you will be pioneering a completely new way to do science. Join the global laboratory!
