| Nanowire clothing could keep people warm, without heating everything else Posted: 07 Jan 2015 09:29 AM PST To stay warm when temperatures drop outside, we heat our indoor spaces -- even when no one is in them. But scientists have now developed a novel nanowire coating for clothes that can both generate heat and trap the heat from our bodies better than regular clothes. They now report on their technology, which could help us reduce our reliance on conventional energy sources.  |
| Foot-powered cell phone charger for world's needy Posted: 07 Jan 2015 09:24 AM PST Engineering students are field-testing their foot-powered cell phone charger in rural villages of the Kingdom of Lesotho. The sophomores hope to sell chargers which use ratchet mechanics.  |
| DNA origami could lead to nano 'transformers' for biomedical applications Posted: 05 Jan 2015 12:10 PM PST If the new nano-machines built at The Ohio State University look familiar, it's because they were designed with full-size mechanical parts such as hinges and pistons in mind. The project is the first to prove that the same basic design principles that apply to typical full-size machine parts can also be applied to DNA--and can produce complex, controllable components for future nano-robots.  |
