Mark Memmott

Mark Memmott is NPR's supervising senior editor for Standards & Practices. In that role, he's a resource for NPR's journalists – helping them raise the right questions as they do their work and uphold the organization's standards.

As the NPR Ethics Handbook states, the Standards & Practices editor is "charged with cultivating an ethical culture throughout our news operation. This means he or she coordinates regular training and discussion on how we apply our principles and monitors our decision-making practices to ensure we're living up to our standards."

Before becoming Standards & Practices editor, Memmott was one of the hosts of NPR's "The Two-Way" news blog, which he helped to launch when he came to NPR in 2009. It focuses on breaking news, analysis, and the most compelling stories being reported by NPR News and other news media.

Prior to joining NPR, Memmott worked for nearly 25 years as a reporter and editor at USA Today. He focused on a range of coverage from politics, foreign affairs, economics, and the media. He reported from places across the United States and the world, including half a dozen trips to Afghanistan in 2002-2003.

During his time at USA Today, Memmott, helped launch and lead three news blogs: "On Deadline," "The Oval" and "On Politics," the site's 2008 presidential campaign blog.

Happy birthday, Mark Zuckerberg.

Not only do you turn 28 today, but at the end of the week Facebook stock is due to go public for the first time.

The social networking giant is expected to be valued around $100 billion and Zuckerberg's worth will then be around $18 billion, as Wired magazine's Steven Levy said earlier today on Morning Edition.

Sunday's news that Yahoo CEO Scott Thompson was stepping down in the wake of questions about his credibility is being followed this morning with accounts about how this is a victory for an activist hedge fund that's been pushing for changes at the Internet search giant.

As the Mercury News reports:

Three high-ranking executives, including one of the most powerful women on Wall Street, are expected to resign from JPMorgan Chase this week because of their roles in the $2.3 billion loss the bank recently suffered when some risky trades blew up in its face.

The Wall Street Journal, which broke that news, also reports that JPMorgan's losses from the "giant trading blunder" keep growing. It cites "people familiar with the situation," as its sources.

Many headlines and stories (including some of ours) have been saying that a "double agent" infiltrated al-Qaida in the Arabian Peninsula and foiled a plot to get another underwear bomb aboard a U.S.-bound passenger jet.

But we've been looking at definitions of spy terms and think that based on what we have been told so far, the person at the center of the story wasn't a double agent.

That character was at least an "agent."

It's incredible enough that Texas Rangers outfielder Josh Hamilton hit four home runs in one game Tuesday night — something that's only been done by 15 other major league players.

One of the most infamous ships still sailing can't dock at its final resting place just yet.

India's Supreme court has ruled that the Exxon Valdez (now called the Oriental Nicety) cannot enter a scrap yard in the western state of Gujarat until its owners can prove the tanker has been cleaned of mercury, arsenic, asbestos, residual oil and other potential contaminants.

"A Sukhoi SuperJet 100, the first new Russian passenger plane in more than two decades" has gone missing while on a "demonstration flight" in Indonesia, Bloomberg News writes.

Russia's RT News adds that "hijacking and a high-altitude crash into a mountain have not been ruled out." A search is underway.

Along with the headlines about Sen. Richard Lugar's loss in Indiana's Republican primary and passage of a ban on gay marriage in North Carolina, there's this news from Tuesday's voting:

More details are emerging about the plot to put another "underwear bomber" aboard a U.S.-bound passenger jet and what the CIA says was its successful foiling of the operation:

As NPR's Dina Temple-Raston reported on Morning Edition:

An Albanian man who more than a decade ago agreed to help the U.S. Justice build a case against a mobster accused of human smuggling has finally won his long-sought quest for asylum in the U.S.

Edmond Demiraj, his wife and adult son have been granted full asylum, NPR's Carrie Johnson reports.

As Carrie reported last year:

The death of children's author Maurice Sendak has brought back many memories for many of us.

This blogger remembers nephew Ben reading Where the Wild Things Are back in the late '60s and being fascinated by what seemed to be a very different, much more interesting, kind of book than I'd been used to as a kid just a few years before.

With same-sex marriage back in the news because of Vice President Biden's comment that he's "absolutely comfortable" with equal rights for partners in such relationships, the pollsters at Gallup are out with this report:

He made this decision before scientists told us that, back in the prehistoric day, dinosaur farts likely contributed to climate change:

Tyler Gold of York, Neb., is now officially named Tyrannosaurus Rex Joseph Gold, the local York News Times reports.

While initial headlines that said a man jumped into a vat of acid to rescue a co-worker at at New Jersey construction site may have overstated what happened just a bit, there's still a dramatic tale to tell.

According to

Saying that "above all else, we both agree that President Obama must be defeated," Rick Santorum on Monday evening endorsed former Republican rival Mitt Romney's presidential bid.

In an email to supporters, the former Pennsylvania senator said that:

Though she won't put a timetable on when activist Chen Guangcheng will be able to leave China with his family and go to the United States, Secretary of State Hillary Rodham Clinton said today that "we're certainly making progress."

Think the players on your favorite team are the most overpaid in the world?

Well, American sports fans, you may not be able to brag (or complain?) about that.

As the number crunchers at Sporting Intelligence reported earlier this month, European soccer teams hold the top four spots when it comes to average pay per player.

By saying Sunday on NBC's Meet the Press that he is "absolutely comfortable" with equal rights for partners in same-sex marriages and that love is at the root of all marriages "whether they're marriages of lesbians or gay men or heterosexuals," Vice President Biden has set off speculation about whether the Obama administration may soon fully endorse same-sex marriage.

The mystery surrounding the death of Army Capt. Bruce Kevin Clark, who collapsed on April 30 while on a Skype call from Afghanistan to his wife back in the U.S., has deepened.

"The United States has for several years been secretly releasing high-level detainees from a military prison in Afghanistan as part of negotiations with insurgent groups," reports The Washington Post, which calls the program "a bold effort to quell violence, but one that U.S. officials acknowledge poses substantial risks."

(Note: We updated the market news in this post at midday.)

A victory Sunday by Socialist presidential candidate Francois Hollande in France and the rejection by voters in Greece of that country's austerity policies have caused a "seismic shift" that threatens the future of the euro,

Update at 2:30 p.m. ET: The news that Adam Yauch of the Beastie Boys has died has now been confirmed by the group's public relations firm.

It was just a week ago that he dropped into our lives.

Now, we're sorry to report that "falling bear" is dead.

In case you're not familiar with the story, it was April 26 when University of Colorado Boulder student Andy Duann snapped a shot of a tranquilized bear as it was falling from a tree on campus.

The bear survived and was released back into the wild about 50 miles from Boulder.

Saying that the rules would "make sure that fracturing operations conducted on public and Indian lands follow common-sense industry best practices," Interior Secretary Ken Salazar this morning issued proposed regulations that would:

-- Require "public disclosure of chemicals used in hydraulic fracturing operations on federal lands."

-- Ensure that "wells used in fracturing operations [on public lands] meet appropriate construction standards."

-- Require operators to "put in place appropriate plans for managing flowback waters from fracturing operations."

As soon as it was learned on Wednesday that former NFL star Junior Seau had killed himself, there was speculation about whether he may have suffered brain injuries during his career that in turn led to depression or dementia.

Sixty seven years later, The Associated Press is apologizing for the way it condemned and then fired one of its correspondents for reporting "perhaps the biggest scoop in its history."

Edward Kennedy was among a small group of reporters taken by Allied military officials to witness the May 7, 1945, surrender by German forces at a schoolhouse in Reims, France.

The nation's jobless rate edged down to 8.1 percent in April from 8.2 percent in March, but just 115,000 jobs were added to private and public payrolls, the Bureau of Labor Statistics reports.

The job growth was well below expectations and has raised new questions about the strength of the U.S. economy.
