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 USAToday.com news blogs: "On Deadline," "The Oval" and "On Politics," the site's 2008 presidential campaign blog.

"I'm now optimistic that we will find the aircraft, or what is left of the aircraft, in the not-too-distant future," the head of the search for Malaysia Airlines Flight 370 told reporters on Wednesday after an Australian ship detected two more pings that may be signals from the plane's black boxes.

A federal judge in Cincinnati said Friday that he will soon rule that Ohio must recognize gay marriages performed in other states.

WVXU reporter Ann Thompson writes that Judge Timothy Black said he will issue that ruling on April 14. She adds that:

As the nation's 43rd president says: "Who woulda thought it?"

Talking with his daughter Jenna Bush Hager during a pre-recorded interview on NBC-TV's Today show, the self-deprecating Bush says:

A little more than three months after he suffered a severe head injury while skiing in France, Formula One racing legend Michael Schumacher is experiencing "moments of consciousness and awakening" his agent says.

The nation's unemployment rate was unchanged at 6.7 percent in March, the Bureau of Labor Statistics reported Friday.

Meanwhile, there were 192,000 more jobs on public and private payrolls last month — a bit under the 200,000 or so economists had expected but still above the average growth in previous months.

As investigators try to determine why Army Spc. Ivan Lopez would open fire on his fellow soldiers at Fort Hood, Texas, stories are emerging about the harrowing minutes on the post Wednesday and what are being described as the heroic actions of the military police officer who confronted the gunman.

"A veteran Associated Press photographer was killed and an AP reporter was wounded on Friday when an Afghan policeman opened fire while they were sitting in their car in eastern Afghanistan," the wire service reports.

Federal agents, art experts and museum curators descended on the home of a 91-year-old man in central Indiana on Wednesday to take control of a huge collection of artifacts from Native American, Russian, Chinese and other cultures.

FBI Special Agent Robert Jones told reporters that the collection's cultural value "is immeasurable," reports RTV6 The Indy Channel.

There were 326,000 first-time claims filed for unemployment insurance last week, up by 16,000 from the week before, the Employment and Training Administration reported Thursday morning.

Although the number increased, claims remained at the lower end of the range they've been in for the past year and were running at a pace close to where they were before the economy sank into its latest recession in December 2007.

A picture is beginning to emerge of 34-year-old Army Spc. Ivan Lopez, who officials have said is the man who opened fire Wednesday at Fort Hood and killed at least three people and wounded another 16 before taking his own life.

The early signs indicate that while Lopez was being treated for depression or some other type of mental issue, he had shown no sign he might be a threat to either himself or others.

On the day after a deadly shooting incident on the grounds of Fort Hood, Texas, in which a gunman killed at least three people, wounded 16 and then reportedly killed himself, there was this welcome news:

Day Two of General Motors CEO Mary Barra's time testifying before Congress about safety problems with her company's cars has been highlighted by a top senator saying the company "repeatedly lied" about its problems and has fostered a "culture of cover-up."

From The Detroit News:

You won't be able to fire away at government drones — if any were to fly by — in Deer Trail, Colo.

A proposal to issue $25 drone hunting licenses was rejected Tuesday by voters in the little town about 55 miles east of Denver.

This year's Peabody Award winners for excellence in electronic media include The Race Card Project from NPR's Michele Norris.

Her project, which was featured in a series of reports on Morning Edition, invites people to distill their "thoughts, experiences or observations about race into one sentence that only has six words."

The first slice of data about job growth in March offers some hope that the U.S. labor market gained some strength:
