Phys.org / The sound of droplets striking water: How cowbirds control two sound sources in the syrinx to create 'liquid notes'

Cowbirds are special among songbirds for the "watery" timbre of their singing, which resembles the sound of falling droplets striking water, a quick burst followed by a fading ripple.

Phys.org / Structural findings reveal how distinct GPCR ligands create different levels of activation

G-protein coupled receptors (GPCRs) are proteins triggered by ligands (protein-binding chemicals) from outside cells to transmit signals inside the cell. These signals are transmitted primarily through the activation of G ...
