At least two people are dead and dozens injured in a 100-vehicle pileup on Interstate 10 in southeast Texas that's being blamed on early morning fog on Thanksgiving Day.

KFDM TV reports that the dead included a man and a woman in a Chevy Suburban that was crushed by a tractor trailer. State troopers told the TV station that between 80 and 120 people were hurt; they were taken to hospitals in Beaumont, Port Arthur and Winnie. The crash occurred southwest of Beaumont, 80 miles east of Houston.

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.

Maybe the end is nigh, after all.

A judge has approved Hostess' plan to liquidate the company, all but assuring that the maker of Twinkies, Ding Dongs, Donettes and Wonder Bread will cease to exist.

The New York Times reports:

Full disclosure: The first thing I said when I saw that Rob Delaney would be talking to NPR's Audie Cornish on today's All Things Considered was that I was curious to see whether he had ever said anything on Twitter — where he has almost 670,000 followers (including me) as of this writing — that they thought they could read on the radio. It's an exaggeration. But not by that much.

New HIV infections have dropped more than 50 percent across 25 developing countries since 2001, the Joint United Nations Program on HIV/AIDS reported on Tuesday. And, transmission of the virus from mothers to infants has decreased by 24 percent in just the past two years.

Update at 3:02 p.m. ET. Jackson Resigns:

The time has come for the pill to be available over-the-counter, the nation's leading group of obstetricians and gynecologists says.

Why? "There's a 50 percent unintended pregnancy rate in the U.S., which is extremely high for a resource-rich country," says Dr. James T. Breeden, president of the American Congress of Obstetrician and Gynecologists. Easier access to oral contraceptives could go a long way to bringing that number down, he tells Shots.

It's been an eventful couple of months for those following the debate over affirmative action.

The FBI has concluded its investigation into the shooting spree at a Sikh temple that left six dead.

After interviewing 300 people and following 200 leads, the FBI concluded that Wade Michael Page acted alone when he opened fire at the Oak Creek, Wis. temple in August.

What's more, reports The Milwaukee Journal Sentinel, because Page killed himself, we may never know his motive. The FBI said that there was no evidence that Page acted because of his connections to white supremacist groups.
