Here is a bit more information in terms of the technical jargon.  However, even a non physicist can appreciate this experiment and spotting:

Now, recent PhD graduate Kyle Ballantine and Professor Paul Eastham, both from Trinity College Dublin’s School of Physics, along with Professor John Donegan from CRANN, have demonstrated a new form of light where the angular momentum of each photon (a particle of visible light) takes only half of this value. This difference, though small, is profound.

What could this mean and what are your wildest ideas in regards to their experiment?  Could this be used in lasers or some other type of application or experiment?  maybe we don’t even want to know.

And in the below video they show a really cool new kind of light bulb from the evening news although it does not use this kind of light.

Check back for updates as they come in!
