    Osmium is Forever: Rare metal’s strength humbles mighty diamond’s

    A new route to materials harder than diamond may have opened with the surprising finding that the rare metal osmium resists compression better than diamond does.

    The Black Hole Next Door

    Microscopic black holes—fleeting replicas of the huge, matter-gobbling ones in space—may be detected soon in our atmosphere and at a big particle collider now being built.

    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.

    Light comes to halt again—in a solid

    By stopping laser light pulses cold in a crystal, storing them, and then releasing them, physicists have achieved the same feat accomplished last year in gases, but this time in a more practical material.
