'Erin Brockovich' Town Faces New Threat

Nov 22, 2012

Hinkley, Calif., is the small town that battled toxic groundwater and inspired the 2000 film Erin Brockovich. Now residents say they are experiencing a sequel to their story.

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.

I'm giving thanks in two ways today, first for things that have lasted, persisted (and here's hoping they keep on going), and second — for change; for our ability to create beauty in new ways. So I'm saying thank you for what's old and what's new.

Thanksgiving, I think, can go both ways.

A few months ago, I let you in on a little secret about Greek yogurt. Not all of this extra-thick, protein-rich yogurt is made the old-style way, by straining liquid out of it it. Some companies are creating that rich taste by adding thickeners, such as powdered protein and starch.
