The Nobel Prize is awarded in three science categories: physics, chemistry, and physiology or medicine. In 2012 each science prize was shared by a pair of researchers. Among this year's six laureates in these categories is the usual number of women: zero.

The interpretation of the ENCODE data as invalidating the "junk DNA" hypothesis was not a "media failure." It was the explicit conclusion of the ENCODE project scientists published in Nature.

Scientists attending a dance performance will undoubtedly relate to the physicality and geometry of dance. The movement through time, the geometry of interactions, the symmetry of the lines, the balance of the bodies. All these have parallels in the physical interactions that occur in every science, from astronomy and physics, to chemistry and biology.

What Is the Key to a Realistic Theory of Evolution?
