Up next, math books get a makeover. You may remember my next guest from her acting roles on "The Wonder Years." Winnie Cooper may ring a bell or "The West Wing." But for thousands of girls today, she's the writer and personality behind a bestselling series of books that aim to teach girls about math. First, there was "Math Doesn't Suck," then "Hot X: Algebra Revealed," and now we're onto geometry.

This is SCIENCE FRIDAY. I'm Flora Lichtman, filling in for Ira Flatow, who's out today. This week, the FDA approved a new influenza vaccine for this year's flu season, and soon enough summer will be over and you'll be standing in line again at your pharmacy or doctor's office, participating in that yearly ritual - your annual vaccination allocation.
You might take that sound for granted. I know I do. That's because most of us hear it all the time, at least in this country. Toilets are everywhere here in the U.S. But a lot of people around the world don't hear that sound every day, because two-and-a-half billion people, with the B, don't have a safe, sanitary place to go to the bathroom, according to the World Health Organization.
This is SCIENCE FRIDAY. I'm Flora Lichtman. We're in the midst of the worst drought in over 50 years. Water tables are dropping faster than they can be replenished, and at the same time an op-ed in the New York Times today says that the United States is estimated to lose about one in six gallons, one in six gallons of clean water every day due to leaky pipes in the ground.
In 1991, a man named Stephen Mobley robbed a Domino's pizza in Hall County, Ga., and shot the restaurant manager dead.
Crimes like this happen all the time, but this particular case became a national story, in part because Mobley seemed so proud of his crime. After the robbery, he bragged about the killing and had the Domino's logo tattooed on his back.
But there was another reason Mobley's case became famous.
By tricking live fish into attacking computer-generated "prey," scientists have learned that animals like birds and fish may indeed have evolved to swarm together to protect themselves from the threat of predators.
"Effectively, what we're doing here is we're getting predatory fish to play a video game," says Iain Couzin, who studies collective animal behavior at Princeton University. "And through playing that game, through seeing which virtual prey items they attack, we can get a very deep understanding of as to how behavioral interactions among prey affect their survival."
Sometime in the next few months, David Daniel probably will have to stand by and watch as bulldozers knock down his thick forest and dig up the streams he loves.
His East Texas property is one of more than 1,000 in the path of a new pipeline, the southern stretch of what is known as the Keystone XL system.
For years, Daniel has tried to avoid this fate — or at least figure out what risks will come with it. But it has been difficult for him to get straight answers about the tar sands oil the pipeline will carry, and what happens when it spills.
