STEVE INSKEEP, HOST:

Sharks have been swarming around southern California beaches for weeks. NPR wanted to know more about why, so we placed a call to Chris Lowe, a professor in marine biology and head of the Shark Lab at California State University at Long beach — or rather, we tried. Lowe was offshore on a boat trapping sharks to tag, and at the appointed time for our interview, Lowe had his hands full ... of shark.

Many Iranians spent the weekend in the streets celebrating the re-election of their president. Hasan Rouhani pledged to keep opening Iran to the world and to push for more freedom at home.

STEVE INSKEEP, HOST:

What difference does it make who's president of Iran?

It's fair to ask the question on this weekend of Iran's presidential election. After all, the president's title makes him sound like the top official, but he is not. Iran's supreme leader, Ayatollah Ali Khamenei, holds far more power.

Nebraska Sen. Ben Sasse shares something in common with President Trump: both are serving in elected office for the very first time.

The similarities pretty much end there.

Sasse earned a doctorate in history. Before his election in 2014, he was a federal health official, and president of Midland University, which is linked with the Evangelical Lutheran Church.

When President Trump fired FBI Director James Comey on Tuesday, Sen. Ben Sasse of Nebraska was one of several Republicans in Washington voicing concern. As details unfolded throughout the week, Sasse, who sits on the Judiciary Committee, continued to call the timing of the firing "troubling," though he maintains there is not yet a need for an independent investigation or special prosecutor to look into Russian meddling in the 2016 election.

At the very start of Hala Alyan's novel Salt Houses, a woman buys a coffee set — a dozen cups, a coffee pot, a tray. It's a simple act that unexpectedly becomes painful. The woman is Palestinian — part of a family displaced after the founding of Israel — and the tray reminds her of an old one she lost in one of the family's many moves.

Alyan builds her story on little moments like that — a peek into the lives of several generations, forced to relocate and resettle. Her characters are lost and looking for a home.

Generations ago, the American Indian Osage tribe was compelled to move. Not for the first time, white settlers pushed them off their land in the 1800s. They made their new home in a rocky, infertile area in northeast Oklahoma in hopes that settlers would finally leave them alone.

As it turned out, the land they had chosen was rich in oil, and in the early 20th century, members of the tribe became spectacularly wealthy. They bought cars and built mansions; they made so much oil money that the government began appointing white guardians to "help" them spend it.
