This week’s stories take us from Ice Age-era California to the mysteries of the dark matter that appears to hold our very universe together. You’ll hear about huge mastodon teeth found sitting in a creek, a sinkhole in front of actor Nicolas Cage’s Malibu home and a discussion of the “Paul is Dead” conspiracy theory. We’ll also learn about how Target has been tracking shoppers using its carts and we’ll hear from a scientist about new research that might reveal some of the secrets hidden in dark matter.
