We summarize the week's science breakthroughs every Thursday.
- Tech
Energy forest
Silicon nanowires can at least double the storage capacity of lithium-ion batteries.
- Tech
Tractor beam
Magnetic nanoparticles selectively bind to specific bacteria and can drag them out of a liquid.
- Computing
Social Networking for Zebras
Scientists are developing a new branch of network theory to understand zebra communities.
- Tech
Crystal clear
Growing nanowires directly on a crystal might lead to high-density memory chips and transparent LEDs
- Tech
A smaller magnetometer
A novel sensor the size of a rice grain can detect magnetic fields as small as those produced by brain or heart waves.
- Tech
Bad Vibrations
Despite computer models and wind tunnel tests, bridges show surprising vibrations and movements that engineers are still learning to cope with.
- Tech
Bucky shrink-wrap
Scientists filmed cage-shaped carbon molecules as they shrank to become buckyballs.

Catch a Wave: Carbon nanotubes go wireless
Despite all the hubbub about carbon nanotubes as possible building blocks of superstrong materials or as components of supersmall electronics, few practical applications have yet come to fruition. Integrating nanotubes into functioning electronic devices has proved especially difficult, but researchers have now built a carbon-nanotube component into a simple radio receiver. TINY RADIO. A single […]

Virtual Worlds, Real Science
Epidemiologists and social scientists are tapping into virtual online worlds inhabited by millions to collect data with real-world uses.
- Tech
CD players could serve as cheap lab tools
Ordinary CD disc players can be adapted to perform chemical assays and possibly medical diagnoses.
