We summarize the week's scientific breakthroughs every Thursday.
- Materials Science
Quick-Change Surface: Material repels water on command
Researchers have modified a gold surface so that it switches from a water-attracting mode to a water-repelling one on command.
- Materials Science
Fracture Protection: Nanotubes toughen up ceramics
The addition of carbon nanotubes to a ceramic material dramatically improves its fracture resistance.
- Materials Science
Carbon nanotubes beam electrons
Researchers have taken a step toward using carbon nanotubes as electron sources in devices such as high-resolution electron microscopes.
- Materials Science
Gold Deposits: Scientists design nanoparticle films
In a step toward a cheaper, easier way to connect computer chips to computers, scientists have patterned semiconductors with a film of extremely small gold particles.

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.
