Understanding sense of smell: Scientists create 3D image of odour molecule

We generally know about particles. Everything is made up of atoms and molecules. We all know this. But when is comes to sense of smell, the molecular level understanding is something that's not common knowledge. What is a smell? How do we perceive it? These are some of the questions scientists have been working upon for decades. And there has now been a breakthrough finally.
