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.

IRA FLATOW, HOST:
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. And if you think you're safe because you're thin, consider that up to 40 percent of thin people have metabolic syndrome, in other words, on the road to type 2 diabetes, even if they can't tell by looking in the mirror.

It's hard to imagine how this teeny little rock — it's not even a whole rock, it's just a grain, a miniscule droplet of mineral barely the thickness of a human hair — could rewrite the history of our planet. But that's what seems to be happening.

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.
Small porpoises once swam in the brackish estuaries of the Colorado River delta. Jaguars stalked the river channels and marshes. It's not like that any more, though. The Colorado River no longer reaches the sea in Northern Mexico. It hasn't since 1983.

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.
You'd have to be heartless not to agree that pandas, especially the youngest of them, are as cute as all get-out. Right? But why?

According to photographer Jamey Stillings, the Ivanpah Solar Electric Generating System (ISEGS) will be the "world's largest concentrated solar thermal power plant" when complete at the end of this year. That's if we want to get all technical.
In plain terms: There's a huge solar plant under construction in the middle of the Mojave Desert, and Stillings has been documenting the process since the very beginning. Did you know this was happening? I didn't.
