Hello, I was watching the finalists videos of the spacelab competition (where teenagers come up with experiments to be done in the ISS) and this kid caught particularly my attention (video here: http://goo.gl/HIbKf ) -at the end when there is written in an anotation that this could be useful to medical research. Do you really think that we could use sponge-like spicules to somehow concentrate drugs near the tumors?
