Skepchick Rebecca Watson has made it to the fourth and final round of a radio contest to be the next great public radio host!
You can listen (and vote on) her entry at the Public Radio Talent Quest site. For this round, she investigates orbs, (not-so) mysterious circles of light that appear in digital photos. As an added bonus, she interviews my dear friend Richard Saunders about them, too.
I have listened to all of Rebecca's contest entries, and this is her best yet. She has a knack for this, and I think she'd make a fine host.
