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.
- 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.
- 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.
- 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.
- 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.
- Physics
Magnetic Overthrow
Researchers have discovered and begun to exploit a fundamentally new way to exert magnetic influences, at least on extremely small scales.
- 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.
- Tech
Nanotubes spring eternal
Researchers have discovered that forests of carbon nanotubes squish and expand like foams, but with extraordinary resilience.
- 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.
- 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.
- 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.
- 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.
