There's a developing story this morning from Paulsboro, N.J., south and across the Delaware River from Philadelphia, where several railroad tank cars have derailed and fallen into a creek after a bridge collapse.

It's being reported that the cars were transporting vinyl chloride, which could ignite and would be highly irritating if breathed in. There are local reports of about 18 people being treated for breathing problems.

The economic effects of Superstorm Sandy continue to be felt. According to the Bureau of Economic Analysis, consumer spending edged down 0.2 percent in October from September, and personal income dipped 0.1 percent.

As Bloomberg News says, "Sandy kept some in the Northeast from getting to work or from shopping at malls and car dealerships."

The White House and congressional leaders continue to talk about taxes, spending cuts and how to avoid the so-called fiscal cliff that arrives at midnight Dec. 31 — when Bush-era tax cuts are set to expire and automatic spending cuts are set to go into effect.

As NPR and others cover the story, we'll try to to point to interesting reports and analyses. Here are three of the latest.

Protesters have streamed into Cairo's Tahrir Square again today, correspondent Merrit Kennedy tells our Newscast Desk.

She says they're there both to demonstrate again against President Mohammed Morsi's decree giving himself sweeping new powers and to express concern about a draft constitution passed early today by Egypt's constitutional assembly.

Good morning. I'm Renee Montagne. The holidays bring out the spirit of giving and giving back what you've pilfered. Recently, we told you about a 1930s teapot returned to the Waldorf Astoria. This morning: a tale of toilet paper. Eastern New Mexico University received a gift box filled with 80 rolls of toilet paper and a Christmas card apologizing for stealing rolls from a dorm years ago. Another inspiring holiday moment, or another TP prank? It's MORNING EDITION. Transcript provided by NPR, Copyright National Public Radio.

Back in 1984, Congress gave authorities the power to let people out of federal prison early, in extraordinary circumstances, like if inmates were gravely ill or dying. But a new report says the Federal Bureau of Prisons blocks all but a few inmates from taking advantage of "compassionate release."

Photos of athletes in their moment of victory or defeat usually show faces contorted with intense emotion. But a new study suggests that people actually don't use those kinds of extreme facial expressions to judge how a person is feeling.

Instead, surprisingly, people rely on body cues.

Hillel Aviezer, a psychology researcher at Hebrew University of Jerusalem in Israel, wanted to see how accurately people can read intense, real-world facial expressions — instead of the standardized, posed images of facial expressions that are usually used in lab tests.

Federal officials are working to send out $1,000 checks in the next few weeks to hundreds of thousands of Native Americans. The money stems from a settlement of the Cobell case, a landmark $3.4 billion settlement over mismanagement of federal lands held in trust for Native American people.

The case was brought by Elouise Cobell, a member of Montana's Blackfeet Tribe, and four other Native Americans in 1996.

"No substantive progress has been made." That's what House Speaker John Boehner had to say Thursday about efforts to avoid automatic spending cuts and tax increases at year's end.

The administration's lead negotiator, Treasury Secretary Tim Geithner, met with congressional leaders from both sides of the aisle Thursday, looking for an agreement on the hazard Congress and the White House created last year to focus their minds on deficit reduction.
