    Magnetism piece fits no-resistance puzzle

    Experimenters have found evidence that a type of magnetic behavior correlated with the onset of zero electrical resistance in some so-called high-temperature superconductors is generic to the whole class of those materials, yielding a possible clue to how the substances lose their resistance.

    Star in a Jar? Hints of nuclear fusion found—maybe

    In a bench-top experiment, atomic nuclei may have fused inside rapidly imploding bubbles of vapor in a liquid bombarded by sound waves, but many scientists find the evidence for bubble fusion unconvincing.
