New collaborative paper in Science: Our colleagues Ekaterina Osipova and Michael Hiller led a team in the discovery that FBP2, a glyconeogenic muscle enzyme, was lost as hovering flight evolved in the hummingbird lineage. Knockouts of this gene in avian cell lines led to an increase in glycolysis, mitochondria production, and mitochondrial respiration, all leading to higher energy efficiency.
