New Thinking About Cavities, Smokey Bear Needs A Rebrand, And Earth As Exoplanet

Pale Blue Dot
NASA/JPL-Caltech
Earth, as seen in 1990 from the interstellar probe Voyager 1, in the image known as "The Pale Blue Dot."

This hour, a potpourri of topics.

First, some new thinking around dental cavities — are they really an oral microbiome problem?

And, as we endure another record-setting fire season, scientists are wondering, does Smokey Bear need a makeover?

Finally, what happens if we look at Earth as an exoplanet?
