Developing our sense of smell: Biologists pinpoint the origin of olfactory nerve cells
When our noses pick up a scent, whether the aroma of a sweet rose or the sweat of a stranger at the gym, two types of sensory neurons are at work in sensing that odor or pheromone. These sensory neurons are ...

Long non-coding RNA molecules necessary to regulate differentiation of embryonic stem cells into cardiac cells
When the human genome was sequenced, biologists were surprised to find that very little of the genome—less than 3 percent—corresponds to protein-coding genes. What, they wondered, was all the rest of ...
