title: Acute Oxygen Sensing--Inching Ever Closer to an Elusive Mechanism.
abstract: The carotid body has long been recognized as the body's primary acute oxygen sensor. For decades, this organ has been reluctant to reveal mechanisms underlying its sensory activity. In this issue of Cell Metabolism, Fernandez-Agüera et al. (2015) take us closer to a fuller understanding of this fundamental process.
