| Hybrid copper-gold nanoparticles convert CO<sub>2</sub> Posted: 11 Apr 2012 09:05 AM PDT Researchers have come up with a solution that may further reduce the energy needed for copper to convert carbon dioxide, while also making the metal much more stable.  |
| Real-life scientific tail of the first 'electrified snail' Posted: 11 Apr 2012 09:05 AM PDT The world's first "electrified snail" has joined the menagerie of cockroaches, rats, rabbits and other animals previously implanted with biofuel cells that generate electricity -- perhaps for future spy cameras, eavesdropping microphones and other electronics -- from natural sugar in their bodies. Scientists say their new biofuel cell worked for months in a free-living snail.  |
| Power without the cord for small devices Posted: 11 Apr 2012 05:40 AM PDT Cell phones and flashlights operate by battery without trouble. Yet because of the limited lifespan, battery power is not a feasible option for many applications in the fields of medicine or test engineering, such as implants or probes. Researchers have now developed a process that supplies these systems with power and without the power cord.  |
