I thought this was sort of a cute story.
Researchers at Kyoto University in Japan published an article in Science in which they determined that a fullerene C60 (buckminsterfullerene, buckyball, etc.) carbon cage molecule can trap a single water molecule. So what? Well, water molecules are notoriously difficult to separate (maybe impossible using other isolation methods?). This capture in a fullerene cage may be a way to study water molecules without the influence of the ever-present effects of hydrogen bonding. I'm not sure if this is going to be a successful way to study the properties of individual molecules of water, but it's a great start.
