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.
