Investigative reporter Julia Angwin was curious what Google knew about her, so she asked the company for her search data. "It turns out I had been doing about 26,000 Google searches a month ... and I was amazed at how revealing they were," she tells Fresh Air's Dave Davies.
In 1911, explorer and British Royal Navy officer Robert Falcon Scott had big plans. He intended to be the first to reach the South Pole, that holy grail of exploration, and claim the distinction for the British Empire.

Scientists have discovered the oldest star in the galaxy. And it's really old, 13.6 billion years. Now to be clear, they had known about this star before but hadn't yet figured out its age. This star is four billion years older than any other star found to date.
Here to more to talk about what this star can tell us about the great beyond is Timothy Beers, of the National Optical Astronomy Observatory in Tucson, Arizona. Thanks so much for being with us.
