The Herschel Space Observatory has given us an unparalleled opportunity to map the cold, dense gas and dust which provides the fuel for star formation. By studying nearby galaxies, we can determine how the star formation cycle proceeds in galaxies with a wide range of environments that are not present in our own Milky Way Galaxy and how the broader galactic environment affects the physical conditions in the interstellar medium. I will present an overview of some new results from Herschel, including spectroscopic evidence for galactic scale outflows in very dusty galaxies and new clues to the primary source of heating for the dust and gas in galaxies.
