ODD PARTICLE OUT
A new state of matter that combines the properties of a superfluid
and a regular fluid may be within experimental reach. Critics have
argued that this theoretical state is unstable, but researchers
report in the 14 January PRL that it can exist if the forces
holding the particles together have the right properties, which
might happen in clumps of ultracold atoms. If found, this strange
state could shed light on the behavior of neutron-star cores.
