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.

Signatures of the Invisible
Contemporary artists worked with CERN particle physicists to create pieces of art that respond to (rather than simply illustrate) the preoccupations of modern physics. This quirky Web site, hosted by the London Institute, provides glimpses of the artworks that resulted from this collaboration. Go to: http://www.signatures.linst.ac.uk/

Computer simulates full nuclear blast
In a classified nuclear-weapon experiment, the world's fastest computer simulated a thermonuclear blast in three dimensions.

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.

Thin Jet Flies Two for One: Double streams yield sheathed nanoballs, fibers
Researchers have used powerful electric fields to stretch liquids into ultrathin jets in which a stream of one liquid encloses the stream of another.

Better Stainless: Analysis could bring pits out of the steel
The key to developing pit-resistant stainless steel is to correct the dearth of chromium atoms around inclusions in the alloy.

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.
