AKRON, Ohio (AP) - Millions of gallons of drilling waste have been injected underground in Ohio, leading some to worry about possible ties to earthquakes.

The drilling practice known as hydraulic fracturing uses chemically-laced water to free oil and gas from underground shale formations. Ohio has 181 wells to inject waste fluid underground.

The Akron Beacon Journal reports that nearly 50 percent of the drilling waste comes from Pennsylvania, which last year banned shipment of the liquid to state water treatment plants.

The "Occupy Wall Street" protests "appears to be settling in for the long term," NPR's Jeff Brady reports.

And as Jeff said on Weekend Edition Sunday:

Note: This report contains an offensive racial epithet. It is an essential part of the story, however.

"Gov. Rick Perry's presidential campaign pushed back quickly and forcefully Sunday against a Washington Post story that linked Perry to a hunting camp known to some by a racially insensitive name," the Austin American-Statesman reports.

The Nobel Prize in medicine has been awarded to three scientists whose discoveries about the human immune system "opened up new avenues for the development of prevention and therapy against infections, cancer, and inflammatory diseases," the Nobel committee announced earlier today.

NPR's board of directors announced Sunday that it had dipped into the world of public television for its new president and CEO: Gary E. Knell, chief executive of the company behind the beloved children's show Sesame Street.

Knell, 57, said he hopes to "calm the waters" at NPR after a rocky year in which the institution lost several top executives and faced renewed challenges to its funding.

Drug shortages mean a growing number of Americans aren't getting the medications they need. That's causing drug companies and doctors to ration available medications in some cases.

"We're now at 213 shortages for this year," says Erin Fox of the University of Utah, who tracks national drug shortages. "That surpasses last year's total of 211. And it doesn't seem like there's an end in sight."

The fabled Chelsea Hotel in Manhattan was home to Mark Twain, Virgil Thomson and Brendan Behan. Arthur C. Clarke wrote 2001: A Space Odyssey, there. Jack Kerouac worked on On the Road. Bob Dylan wrote "Sad-Eyed Lady of the Lowlands." Artists Larry Rivers and Mark Rothko, and scores of painters and photographers also spent creative time there. But now the future of the hotel is up in the air.

The Joint Select Committee on Deficit Reduction — also known as the supercommittee — created by Congress this summer has just seven weeks to agree on a plan reducing projected deficits by more than a trillion dollars.

If that panel of six Democrats and six Republicans deadlocks, or if Congress rejects its work, by law automatic across-the-board budget cuts — half of them from defense spending — will be triggered. Already, talk is growing of undoing that trigger.

The U.S. economy is struggling to grow. The European Union is trying to contain a debt crisis. And, in a case of bad timing, the world's fastest-growing major economy, China, is trying to slow down.

Shanghai has been one of the world's hottest real estate markets, but it's too hot for Chinese officials who are fighting high inflation and what some fear is a housing bubble.

Earlier this year, the Shanghai government tried to slow down real estate sales by restricting people from outside the city from buying more than one property.

If the U.S. Supreme Court term opening Monday were a Broadway show, all eyes would be on the stars waiting in the wings.
