Breathe in and Straighten Your Back: Hypoxia, Notch, and Scoliosis

In this issue of Cell, Sparrow et al. propose a new mechanism for sporadically occurring congenital scoliosis in which Notch signaling and hypoxia converge in the embryo on somite patterning via the segmentation clock. This interaction between hypoxia and a predisposed genetic background might underlie other birth defects with incomplete penetrance.

Cool Dentists

Scientists have...
