Get out a pencil and paper and your graphic calculator because it's time for a little math review. And we'll warm up with some algebra, move on to imaginary numbers, then the quadratic formula, and we're going to finish up with a bit of vector calculus, how about some probability theory thrown in. No, no, no, I'm just joking. Don't turn off the radio just yet.

The Ig Nobel Prizes honor scientific research that, in the words of Master of Ceremonies Marc Abrahams, "first makes you laugh, and then makes you think." This year's prizes, awarded in late September, include citations for research into mysteriously green hair, potentially explosive colonoscopies, and the creation of equations that model the back-and-forth swing of a ponytail in motion.

Albert Einstein was a smart guy. Everybody knows that. But was there something about the structure of his brain that made it special?
Scientists have been trying to answer that question ever since his death. Previously unpublished photographs of Einstein's brain taken soon after he died were analyzed last week in the journal Brain. The images and the paper provide a more complete anatomical picture and may help shed light on his genius.
The shellfish industry on the West Coast has had a bumpy few years and increasingly, it is pointing to climate change as the cause. Scientists believe the oceans are becoming more acidic as they absorb the increasing amounts of carbon dioxide in the air, and they are not sure if oysters and other shellfish will be able to adapt to this change. Lauren Sommer, from member station KQED, has this report.
LAUREN SOMMER, BYLINE: Terry Sawyer does a brisk business in oysters.
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.
For Thanksgiving, NASA's space food experts always try to make sure astronauts get to enjoy traditional holiday fare, even if its not exactly home cooking. And being so far from home, astronauts can get pretty attached to their comfort foods.
This year, Kevin Ford, the commander of Expedition 34 and currently working at the International Space Station, says he has the ingredients to make one favorite Thanksgiving dish the NASA nutritionists may not have anticipated: Candied yams with marshmallows.
The yams are thermostablized and come in a plastic pouch.

Why people yawn is a mystery. But yawning starts in the womb.
Past studies have used ultrasound images to show fetuses yawning, but some scientists have argued that real yawns were getting confused with fetuses simply opening their mouths.
So Nadja Reissland, a researcher at the University of Durham in the United Kingdom, used a more detailed ultrasound technique to get images of fetal faces that could distinguish a true yawn from just an open mouth.
