A chemically unstable ostrich eggshell peptide survives for at least 3.8 million years at the equator, stabilized by strong mineral interactions.

A continuum of genome relationships is discovered through comparative genomics of 627 sequenced mycobacteriophages isolated and characterized in an integrated research/education initiative.

A new specimen of Heterodontosaurus elucidates how ornithischian dinosaurs evolved a body plan substantially different from that of other dinosaurs and what these differences meant for their breathing.

Experiments show that pathogens spread more easily among relatives causing increased mortality, but such costs are cancelled out by the benefits of living with kin when pathogens are rare.

Angiopoietin-like proteins signal through notch via receptor interaction and can regulate Notch cleavage/activation.
