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.
Maurice Geddie of Brooklyn's Red Hook neighborhood picks up a free turkey donated by a local grocery store. He's hoping his wife will be willing to cook it, though she's been stuck cooking for storm victims at shelters for weeks.
It's been almost a month since Superstorm Sandy slammed into the Northeast, and for many people, it means the first Thanksgiving outside of their destroyed homes or without the friends or family they usually visit.
In New York City, Thanksgiving has been mass-produced in shelters, churches and community centers where thousands upon thousands of storm victims can find free meals.
Many of them are sharing their first post-storm Thanksgiving with people who are hungry year-round.
At least two people are dead and dozens injured in a 100-vehicle pileup on Interstate 10 in southeast Texas that's being blamed on early morning fog on Thanksgiving Day.
KFDM TV reports that the dead included a man and a woman in a Chevy Suburban that was crushed by a tractor trailer. State troopers told the TV station that between 80 and 120 people were hurt; they were taken to hospitals in Beaumont, Port Arthur and Winnie. The crash occurred southwest of Beaumont, 80 miles east of Houston.
World maps help us make sense of the world around us, and our place in it.
While mapmakers may portray their world maps as accurate, scientific and neutral, every single one describes the world from a certain worldview and culture. From ancient Babylonia to the Renaissance, cartographers have been driven by politics, religion, emotion and math.
