*Anti-nuclei* http://arxiv.org/abs/1208.3614 Groups are looking for evidence of anti-nuclei in cosmic rays. Anti-protons are one thing, but seeing anything heavier than anti-Helium would be strong evidence for their being regions of the universe with anti-matter dominating.

"If this works, then you can really forget about stealth in space. Also, this is the first step toward developing the Total Perspective Vortex."
So much for cloaked ships.

Space Solar Power
To achieve commercially useful levels of storage, around 1 GW·h
), a SMES installation would need a loop of around 100 miles (160 km). This is traditionally pictured as a circle, though in practice it could be more like a rounded rectangle. In either case it would require access to a significant amount of land to house the installation.
Good for space based power that doen't need large surface areas for photovoltaric arrays?
