Bionic bee pulls nail out of a wall

As Colony Collapse Disorder, mites and other threats to the world’s honeybee population incite worries about how agriculture might be affected, Harvard University researchers have a futuristic solution: RoboBees. These bionic bees could fly from flower to flower, pollinating crops the same way living honeybees would. While they’re not exactly a replacement for nature, they could be a real help, and also offer search-and-rescue capabilities.
