A number of significant scientific events occurred in 2014, including the first robotic landing on a comet and the first complete stem-cell-assisted recovery from paraplegia. The year also saw a significant expansion in the worldwide use and sophistication of technologies such as unmanned aerial vehicles and wearable electronics.
In November 2014, the Philae lander launched by the European Space Agency's Rosetta spacecraft performed the first successful landing on a comet (Philae's target, Comet 67P, pictured).
