Just listening to Radio 4 and getting a bit annoyed. A few weeks ago, there was a daft story about invisibility cloaks.

Look, I am sure that it works really well, and potentially it’s going to have major technological applications. But it only works with one wave length. In what sense is this invisibility? Have we really reached the stage, where scientific reporting is based purely on how many inappropriate cultural references we can throw in? I like Harry Potter, but this is really starting to put me off.
