I just heard about this competition--reposting from Amina Qutub's G+ contributor's announcement:
Join the crowd to make an impact on cancer research!
The crowd-sourced DREAM 9 Challenge Wiki site opened to all interested scientists, mathematicians, computer scientists, engineers and clinicians around the world. This DREAM Challenge's goal is to use the wisdom of the crowds to develop new algorithms to understand and treat leukemia, using data provided by M.D. Anderson Cancer Center.
To join, learn about the Challenge, & interact with the data using new visualization tools, visit the DREAM Wiki: https://www.synapse.org/#!Synapse:syn2455683/wiki/
Thought this might be interesting to some of the folks here.
