A common enzyme connects notch signaling and Alzheimer's disease.

Biology in its broadest sense is a multifaceted endeavor aimed at solving a puzzle with a finite, but extremely large, number of pieces. Often it is hard to predict how wide the gap separating two individual bits of knowledge within the larger picture would be. Therefore, when researchers working in diverse fields simultaneously realize that their fragments of the puzzle fit together, what appeared as an insurmountable distance is bridged rapidly as the remaining pieces are fitted into place. Several studies published recently by developmental biologists, neuroscientists, and researchers who are interested in the identification of therapeutic targets and treatments for Alzheimer’s disease (AD) have tied together diverse
