All Stories by Peter Weiss
- Tech
Helping circuits get enough oxygen
The search for new insulators needed for making ever-smaller circuits may get a boost from a new electron microscopy technique sensitive to a single oxygen atom missing from a crystal layer.
- Tech
Sound power for deep-space travel beyond sun’s reach
An unusually efficient new type of power unit for spacecraft uses sound to convert heat to electricity.
- Materials Science
Face to Face: Crystal-growth method bodes electric payoff
A new method for growing silicon carbide eliminates crystal defects that have long prevented the compound's wider use in electric devices.
- Materials Science
Warm Reflections: Window tint kicks in when it’s hot
A novel window coating automatically transforms into a heat mirror only when warmed above room temperature.
- Physics
Antimatter loses again
A study of subatomic B mesons reveals a new way in which the laws of physics differ for matter and antimatter, providing another clue to why there's almost no antimatter in the universe today.
- Tech
Neutrons may spotlight cancers
Researchers have taken a first step toward developing neutron beams as a medical diagnostic tool that might provide earlier detection of cancers.
- Physics
Starting from Square One
Physicists appear to have wedded the arcane theory of quarks to cutting-edge computer science, giving themselves tools for precisely predicting properties of subatomic matter and possibly observing new physical phenomena.
- Physics
Inside Plastic Transistors: Crystal-clear window opens on hidden flows
By creating a new type of plastic transistor, researchers have identified crucial details regarding electric flow through plastic semiconductors.
- Physics
Feel the Force: Magnetic probe finds lone electron
Scientists have observed a single electron's magnetism.

- Physics
Quantum snare entraps key fifth photon
By coaxing five quantum particles into a state of entanglement, physicists have taken an important step toward dependable quantum computers and more-versatile schemes for transferring quantum information.
- Tech
Nanorods go for the gold
Gold blobs grown onto the ends of tiny, rod-shaped crystals provide potential points for electric contact and chemical liaisons that could enable such semiconductor bits to self-organize into complex circuits or structures.
