  • How Earth sheds heat into space September 24, 2018
    Just as an oven gives off more heat to the surrounding kitchen as its internal temperature rises, the Earth sheds more heat into space as its surface warms up.

  • Birds' voiceboxes are odd ducks September 24, 2018
    Birds sing from the heart. While other four-limbed animals like mammals and reptiles make sounds with voiceboxes in their throats, birds' chirps originate in a unique vocal organ called the syrinx, located in their chests.
