Nothing goes better with a turkey sandwich than a full day of college football. The season is winding down. There's a lot at stake as teams look ahead to bowl games and to the national title. Thanksgiving weekend brings about some of the great rivalries in college football. And here to give us a preview of the weekend is Chris Dufresne, who covers college football for the L.A. Times.

An air embolism in a narrow water-transporting cell in a leaf of a walnut tree, captured using light microscopy. Drought stress increases the likelihood of embolism, reduces photosynthesis and may eventually lead to plant death.
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.
