Cool Wire: Nanostructure boosts superconductor
The extraordinary performance of a prototype superconductive wire is encouraging superconductivity specialists, even though the prototype is unlikely to be mass-produced.
- Tech
Corralling Brownian motion
A new microscope system uses electrically controlled fluid motions to counteract Brownian motion, preventing those random jitters from driving proteins, viruses, and other tiny objects out of the field of view.
