According to the EPA, more than 2.5 million tons of electronic waste, or e-waste, is produced each year in the U.S. Derek Markham, a contributing writer for Treehugger.com, discusses the global impacts, and why you should think twice before discarding your old cell phone.
What's it like to live--and cook--on Mars? To find out, researchers are simulating Mars missions in Russia, and on the slopes of a Hawaiian volcano. Kim Binsted talks about her study to whip up tastier space food. Porcini mushroom risotto, anyone? And sleep expert Charles Czeisler talks about how humans adapt to the 24.65-hour Martian day.
Next up, yet another way that genetics is giving rise to new ways to treat cancer. A few months ago I was at a conference focusing on individualized medicine; that's treating people individually, using medicines that were designed for each person's genetic makeup. It's a new frontier that we'll be talking about more.
This is SCIENCE FRIDAY. I'm Ira Flatow. This isn't going to take you by surprise, but America is fat. One in three adults is obese. For kids, it's one in six. But don't forget the infants. Doctors say there's now an obesity epidemic among six-month-old babies.

Part of the nation's physical landscape is changing. Nature writer and commentator Craig Childs has been watching the dramatic transformation of a mighty river that is running dry.

Xiao Liwu made his public debut Thursday at the San Diego Zoo. Fans crowded around the exhibit, their camera lenses extended, hoping to catch a glimpse of the 5-month-old giant panda cub. If they're lucky and actually do see the 16-pound panda (his Chinese name means "Little Gift"), there'll be much oooing and aaahing.
