Scientists who study forests say they've discovered something disturbing about the way prolonged drought affects trees.
It has to do with the way trees drink. They don't do it the way we do — they suck water up from the ground all the way to their leaves, through a bundle of channels in a part of the trunk called the xylem. The bundles are like blood vessels.
When drought dries out the soil, a tree has to suck harder. And that can actually be dangerous, because sucking harder increases the risk of drawing air bubbles into the tree's plumbing.
There have been a number of books about great Jewish athletes, starring legendary baseball players like Sandy Koufax or Hank Greenberg, the "Hebrew Hammer." But a new book doesn't focus only on Jewish players — it looks at the myriad ways Jews have contributed to the American athletic landscape. Jewish Jocks: An Unorthodox Hall of Fame is a collection of essays compiled and edited by Franklin Foer and Marc Tracy of The New Republic magazine.
Foer and Tracy join NPR's Linda Wertheimer to discuss the rise of Jews in big-league sports.
Good morning. I'm Renee Montagne. In Sweden, Anna Erickson got a letter accepting her into the local preschool. It had gone out to everyone in town born in '07. Great, except for one detail: Anna was born in 1907. So the 105-year-old won't be showing up to class. In New York, the elegant Waldorf-Astoria experienced a blast from the past this week when a man returned one of the hotel's silver-trimmed teapots, pilfered back in the 1930s. It's MORNING EDITION.
