  1. Physics

    Thermonuclear Squeeze: Altered method extends bubble-fusion claim

    A technique that some scientists claim generates thermonuclear fusion in a benchtop apparatus apparently works even without its controversial neutron trigger.

  2. Tech

    Transistors sprout inner forests

    By combining nanowires and conventional transistor structures, researchers are creating novel transistors with improved performance and the potential to be easily manufactured.

  3. Tech

    Hearing implant knows where it goes

    A new type of cochlear implant includes sensors whose signals may help surgeons insert the device more deeply into the inner ear and so provide better hearing.

  4. Physics

    Quantum Chip: Device handles ions as if they were data

    A new microchip can trap and move an ion, preliminary steps toward carrying out quantum computations on a chip.

  5. Tech

    Facing a hairy electronics problem

    Investigating why kinky metal filaments sprout spontaneously on electronic- circuit cards, researchers have found that the way metal films have been electroplated onto the surface in the first place plays a lingering role.

  6. Physics

    Magnetic Overthrow

    Researchers have discovered and begun to exploit a fundamentally new way to exert magnetic influences, at least on extremely small scales.

  7. Tech

    Narrow Escape: Sharp nanogutters hustle out wetness

    Nanochannels with sharply tapered edges can dramatically boost fluid flow rates and potentially play a role in improved microchip cooling, fabrics to wick away perspiration, and other uses.

  8. Tech

    Nanotubes spring eternal

    Researchers have discovered that forests of carbon nanotubes squish and expand like foams, but with extraordinary resilience.

  9. Physics

    Peek-a-bubble

    Physicists made a stable, doughnut-shaped air bubble in water by encasing the gas ring in beads that form a stiff shell.

  10. Physics

    Instant Nano Blocks: One-step process makes trillions of DNA pyramids

    Researchers have unveiled a three-dimensional building component that can be created from DNA in a simple procedure.

  11. Computing

    Network Inoculation: Antivirus shield would outrace cyber infections

    As a new way to protect a computer network from viruses, an epidemic of antiviral protection could theoretically propagate faster through the network than the virus itself, thanks to a novel topological twist.

  12. Materials Science

    Atom Hauler: Molecular rig snags multi-atom loads

    Specialists in atomic-scale construction can now use a new molecule to gather small groups of atoms and drop them, as clusters, at specific locations.
