photons are considered to have no mass, but that hasn't stopped scientists from figuring out to precisely mould them into shapes up to 4 metres (13.1 feet) long.
In testing the ways light interacts with matter, the researchers
found that the specific shape of a photon alters its effect on an atom.
The discovery not only tells us more about the nature of light, but
could also inform the development of the quantum technologies we'll use
in the future. More.
