Submission + - CalTech astronomers predict that 1 in 10,000 stars is composed entirely of metal

porkchop_d_clown writes: A recently discovered aerodynamic phenomena of turbulence, called 'preferential concentration' causes heavier materials to be sorted out of more turbulent areas, increasing their concentration in eddies.
