Bill Chappell

Bill Chappell is a blogger and producer who currently works on The Two Way, NPR's flagship blog. In the past, he has coordinated digital features for Morning Edition and Fresh Air, and edited the rundown of All Things Considered. He frequently contributes to other NPR blogs, such as All Tech Considered and The Salt.

Chappell's work at NPR has ranged from being the site's first full-time homepage editor to being the lead writer and editor on the London 2012 Olympics blog, The Torch. His assignments have included being the lead web producer for NPR's trip to Asia's Grand Trunk Road, as well as establishing the Peabody Award-winning StoryCorps on NPR.org.

In 2009, Chappell was a key editorial member of the small team that redesigned NPR's web site. One year later, the site won its first Peabody Award, along with the National Press Foundation's Excellence in Online Journalism award.

At NPR, Chappell has trained both digital and radio staff to use digital tools to tell compelling stories, in addition to "evangelizing" — promoting more collaboration between legacy and digital departments.

Prior to joining NPR in late 2003, Chappell worked on the Assignment Desk at CNN International, handling coverage in areas from the Middle East, Asia, Africa, Europe, and Latin America, and coordinating CNN's pool coverage out of Qatar during the Iraq war.

Chappell's work for CNN also included producing Web stories and editing digital video for SI.com, and editing and producing stories for CNN.com's features division.

Before joining CNN, Chappell wrote about movies, restaurants and music for alternative weeklies, in addition to his first job: editing the police blotter.

The U.S. says enough progress has been made in talks with Iran on its nuclear program to warrant an extension of Tuesday's 6 p.m. ET deadline by a day.

She said Secretary of State John Kerry, who was scheduled to leave the talks Tuesday, will remain until Wednesday.

Things are getting wild at the British prime minister's residence. No, that's not a reference to the official start of the 2015 election campaign: Photographers who staked out No. 10 Downing St. Monday captured images of a fox slinking past the door of the famous residence.

And that's not the only animal that appeared at Prime Minister David Cameron's door on Monday. His cat, Larry, popped out for some fresh air — and shared an awkward moment with a police dog.

Other details, such as rules controlling enrichment, the length of the deal and how it would be enforced, also remain unsettled.

An enormous limestone cave in Vietnam is the subject of a jaw-dropping new video that uses aerial drones to show its immense scale and beauty. Hang Son Doong is the world's largest cave, featuring a river and huge "skylights" that have allowed trees and wildlife to flourish within it.

Ole Miss scored 62 points in the second half last night to dig its way out of a hole and into the big bracket, on the first day of the NCAA men's basketball tournament. At the half, the Rebels were 17 points behind BYU — which had pulled off its own miracle comeback just three years ago.

BYU suffered the loss in Dayton, where it had made a historic 25-point comeback in the 2012 NCAA tournament.

The eight men are accused of killing "over 1,000 civilians of Muslim nationality, whose remains were identified in mass graves at several locations," reports Serbian news agency B92.

A test on an envelope that arrived at the White House Mail Screening Facility on Monday indicates that it contains cyanide, according to the Secret Service. The agency did not announce to whom the letter was addressed. Further tests are being conducted to confirm the results.

Secret Service spokesman Robert Hoback says:

Citing both potential harm to society and the Computer Crimes Act, Thailand's Culture Ministry is urging women to resist what it says is a new trend of taking photos that focus on the midriff and the lower portion of their breasts.

The warning was issued Monday — and a ministry official acknowledged that in speaking out against an online trend, the agency ran the risk of drawing more attention to it.

Answering pointed questions about new claims of misconduct by his agents, Secret Service Director Joseph Clancy says he had a "good stern talk" with his staff about why he wasn't told sooner about an incident in which two senior agents who were apparently drunk drove a government vehicle through an area at the White House complex where their colleagues were investigating a suspicious package.
