When bosons behave like fermions

Physicists have blurred the distinction between bosons and fermions by coaxing a one-dimensional gas of atoms into a Tonks-Girardeau gas for the first time. The creation of this novel quantum state, which was first predicted about 40 years ago, represents yet another breakthrough in the field of ultracold physics (B Paredes et al. 2004 Nature 429 277).
