Fermionic Condensate Unveiled
From the free section of Nature online (registration required) Fermions chill out: New form of quantum matter unveiled:
"Jin and her colleagues made the condensate by cooling a gas of about half-a-million potassium atoms to within 50 billionths of a degree above absolute zero, the coldest temperature possible. They used a magnetic field to coax the atoms to stand close together in pairs, although without actually bonding. These atomic pairs bear a good likeness to the electrons that produce superconductivity."
Update: Less experimental detail, but more background provided by this Physics News Update story.
