Getting Warped
While museum displays such as simulations of warped space-time acquaint visitors with the ideas behind Albert Einstein's scientific discoveries, other galleries of artifacts, letters, and even film footage reveal the multifaceted man that Einstein was.

Light chips find a place to take root
The fabrication of an artificial, inside-out opal of silicon promises to make all-optical microchips possible
- Physics
Atom microchips get off the ground
Becoming smaller and more versatile, microchips using atoms instead of electrons promise both to improve atomic physics experiments and to pave the way for new technologies such as quantum computers.

Stretched matter goes to unusual extremes
Researchers have discovered that several unusual forms of matter with extremely high or low densities can expand laterally in one direction and contract in another when extended.

Identity Check: Elusive neutrinos morph on Earth, as in space
Strengthening a challenge to the prevailing theory of particle physics, measurements of elusive particles called antineutrinos from nuclear reactors suggest that no neutrino types, be they matter or antimatter, have stable identities.
