Rob Burnett started working with David Letterman as an intern in 1985 and never left, even when the talk-show host moved from NBC to CBS. During the course of his 29-year tenure, Burnett evolved from intern to head writer to executive producer of the Late Show with David Letterman, a position he held through last night's final show.

Prosecutors in Pakistan's Punjab province have charged 106 people in connection with the gruesome mob killing of a Christian couple who were incinerated in a brick kiln for allegedly desecrating a copy of the Quran.

In November, Sajjad Mesih and his wife, Shama — who was pregnant when the couple in their 20s was killed — were beaten and thrown into the kiln they tended as laborers.

Another sequel, another chance for Hollywood to hurl metal hither and yon and make with the flashy summer blockbuster blow-'em-ups. Yawn, right?

A new batch of 6,500 words are now available to Scrabble players, after publishing house Collins updated its widely used Official Scrabble Words list Thursday. The list includes tech jargon and slang, such as pwn, twerk and shizzle.

Also added: aji (the pepper), coqui (the frog) and the more old-fashioned ixnay and zowee. (See a longer list at the bottom of this post.)

Florida postman Doug Hughes made headlines last month for landing his gyrocopter on the lawn in front of the Capitol building.

In an interview with NPR, Hughes said he "made every effort to send word ahead" about the flight, but also knew he would be taken into custody. He made the flight anyway, he said, to "get a message to the American people — not that there's a problem with Congress but that there are solutions to the problem."

The Florida mailman who landed a gyrocopter on the lawn of the Capitol last month appeared in court today and pleaded not guilty to all six charges against him.

Douglas Mark Hughes was charged Wednesday and faces up to 9 1/2 years in prison.

NPR's Peter Overby reported on the charges against Hughes:

Rip open a little package of baker's yeast from the supermarket, peer inside, and you'll see your distant cousin.

That's because we share a common ancestor with yeast, and a new study in the journal Science suggest that we also share hundreds of genes that haven't really changed in a billion years.

Edward Marcotte, a biologist at the University of Texas at Austin, knew that humans and yeast have thousands of similar genes. But, he wondered, how similar are they?

Sen. Rand Paul of Kentucky, a Republican, held the floor of the Senate for 10 1/2 hours Wednesday afternoon and evening, airing his objections to the NSA bulk collection of telephone records in the U.S.

Many of the accounts of this lengthy performance referred to it as a filibuster, or a near-filibuster, or some kind of filibuster or other.

It was none of the above.

The mother of a University of Massachusetts, Amherst, student who died of a heroin overdose is frustrated that no charges have been filed against the dealer, 19 months after she found her son Eric Sinacori dead in his off-campus apartment.

Francesca Sinacori hadn’t known her son had recently been arrested by university police, and was enlisted as a police informant in exchange for dropping charges. The university has since suspended its drug informant program.

Officials say as many as 105,000 gallons of oil have spilled from a ruptured pipeline along the Santa Barbara coast, and around 21,000 gallons of that is believed to have made it into the waterways.

California Governor Jerry Brown yesterday declared a state of emergency because of the spill, and biologists are working on beaches to try to save wildlife from the oil.

Militants with the self-proclaimed Islamic State overran the famed archaeological site at Palmyra early today, just hours after seizing the central Syrian town.

Palmyra is a Unesco World Heritage site and there are concerns the extremists might destroy some of the priceless ruins, as they have done in neighboring Iraq.

The Islamic State’s capture of the town of Palmyra late yesterday was a stunning triumph for the militant group, only days after it captured the strategic city of Ramadi in Iraq’s largest Sunni province.

Vision loss and blindness can be devastating, isolating people and increasing their risk of illness and death. And that burden falls hardest on people in poor communities, especially in the South.

More than three quarters of the counties with the highest rates of severe vision loss are in the South, according to an analysis published Thursday in Morbidity and Mortality Weekly Report. It's the first analysis of severe vision loss at the county level.

President Obama says that while the loss of Ramadi to the self-declared Islamic State is a "setback," he doesn't think the U.S. is losing to the militant group.

The study “Suicide Trends Among Elementary School Aged Children in the United States,” published in this week’s JAMA Pediatrics, shows that the suicide rate among young black children has nearly doubled over the last two decades.

The extra point in football is one of the NFL’s easiest plays. This week, the league and owners agreed to make it a little more dramatic.

Starting this fall, the play will be moved back, from the 2-yard line to the 15-yard line. This change was one of three proposals the considered this week at the NFL’s spring meeting.

Here & Now’s sports analyst Mike Pesca joins host Jeremy Hobson with details.

To discover the new frontier of urban farming, you'll have to look up — and look sharp — for hanging fruit.

The sales pitch for contact lenses that help kids see better by reshaping their corneas sounds futuristically appealing. Sleep overnight in the lenses, pop them out in the morning and experience perfect or near-perfect vision for an entire day.

Beth Levenson of Williamsburg, Va., thought the lenses, even at a price of $2,000, seemed ideal for her son Logan, then 9, who played on several sports teams.

The Senate has voted to limit debate on a bill that would grant the White House "fast track" negotiating authority and clear a path for the Obama administration's trade deal with 11 Pacific Rim nations.

Reuters says the 62-38 vote, which clears a filibuster hurdle, boosts "hopes for a deal that is central to President Barack Obama's strategic shift toward Asia."

Many Democrats oppose the Asia-Pacific treaty, saying free-trade deals cost U.S. jobs, but the White House maintains that U.S. producers need access to foreign markets.

African-American women can be at risk of heart disease even if they don't have metabolic syndrome, a study finds.

That's a problem, because the current thinking is that metabolic syndrome — defined as high triglycerides, bad cholesterol, abdominal fat, high blood pressure and impaired glucose metabolism — is the big risk factor for heart attacks and strokes.

The picture with women appears to be a lot more complicated, especially when you compare women in different racial or ethnic groups.

In his New York Times column this week, Charles Blow discussed bikers and thugs in the aftermath of the Waco shootout on Sunday.

On April 22, WNBA stars Brittney Griner and Glory Johnson were arrested and charged with assault and disorderly conduct after the couple reportedly had a fight in their Phoenix home. A week later, Griner pleaded guilty to disorderly conduct and agreed to participate in a 26-week domestic-violence diversion program. On May 8, the couple got married in an outdoor wedding that was written up in The New York Times, and then, on May 15, each woman received an unprecedented seven-game suspension from the WNBA.

Citing the completion of a pretrial intervention program, a New Jersey judge has dismissed a felony assault charge that was filed against former Baltimore Ravens running back Ray Rice over a now-infamous incident in which Rice struck his then-fiancee in a casino elevator.

Rice hit Palmer during an argument while they were visiting Atlantic City, N.J., in February of 2014. A month later, he was indicted on a charge of third-degree aggravated assault. He then entered into a one-year pretrial program that would allow him to avoid a trial.

Do you ever feel like communication — in this Age of Communication — is more confused and confusing than ever? Does anybody even read whole messages anymore — beyond the subject line or the first screen? Do you get tangled up in threads and bewildered by attachments? Do txt msgs n-furi-8 u?

Here's the real question: Are all these communication devices truly improving interaction between humans or just providing more opportunities for miscommunication?

Malaysia's prime minister has ordered the navy and coast guard to search for stranded Rohingya migrants in the Andaman Sea, a day after Kuala Lumpur and Jakarta agreed to take boatloads of desperate refugees who have been in limbo for weeks since fleeing persecution in Myanmar.

Following the self-declared Islamic State's capture of Palmyra, concern today is turning to the security of the ancient Syrian city's archaeological sites and fears that the Islamist extremists might try to destroy them, as they have done elsewhere.

America's ongoing war on fat, which aims to save this country — and especially its young people — from a costly and damaging epidemic of obesity, turns out to be dangerous all on its own: It exacts a severe psychological and physical toll on the very individuals it purports to help, according to an upcoming book.

The Texas-based company responsible for the undersea pipeline that has leaked tens of thousands of gallons of oil into the sea near the coast at Goleta, Calif., has a history of federal safety violations, The Los Angeles Times reports.

RENEE MONTAGNE, HOST:

When the final episode came, after weeks of accolades and tributes to his genius, David Letterman made sure he punctured the emotion of the moment with a little old-fashioned, self-deprecating sarcasm.
