Has the Earth's inner core stopped turning? A new study draws attention to what's going on 3,000 miles below our feet. This Friday, we'll examine why scientists are debating seismic records to better understand what's happening at the core of it all. We'll then travel to rural China where many families are reuniting for the first time in years during the first week of the Lunar New Year. Join us for a firsthand look at the world's largest annual human migration. And last up this week, we'll visit Antarctica to get a bird's eye view of a massive iceberg roughly the size of London.
