Science : For more than 50 years, astrophysicists have speculated that inside a superdense neutron star, nuclear matter might flow without any resistance whatsoevermuch like electricity does in earthy materials known as superconductors, writes Adrian Cho for Science. Now, two teams say they have direct evidence of such bizarre “superfluidity” in a neutron star, and other researchers seem convinced. Dany Page, a theoretical astrophysicist at the National Autonomous University of Mexico in Mexico City, and colleagues published their results in Physical Review Letters , while Wynn Ho of the University of Southampton in the UK and Craig Heinke of the University of Alberta in Edmonton, Canada, and colleagues report a similar analysis in a paper in press at the Monthly Notices of the Royal Astronomical Society.
