Newly developed tiny antennas, likened to spotlights on the nanoscale, offer the potential to measure food safety, identify pollutants in the air and even quickly diagnose and treat cancer, according to the Australian scientists who created them. In the Journal of Applied Physics, they describe these and other envisioned applications for their nanocubes in "laboratories-on-a-chip."

Ultra-Thin Nanowires Can Trap Electron ‘Twisters’ That Disrupt Superconductors

View | Comment

Superconductor materials are prized for their ability to carry an electric current without resistance, a valuable trait crippled or lost when electrons swirl into tiny tornado-like formations called vortices. To keep supercurrents flowing at top speed, scientists have figured out how to constrain troublesome vortices by trapping them within extremely short, ultra-thin nanowires.
