It's nightfall in Washington, D.C., at the end of the evening shift, when the throngs of students on school field trips have slowed to a trickle at the Vietnam Veterans Memorial.

With a flashlight in one hand and a clear plastic bag in the other, Bob Herendeen walks the length of the austere, black granite wall. The National Park Service ranger surveys the things visitors have left at the memorial: American flags, wreaths, flowers.

More than a decade ago, author Neil Gaiman wrote a short story that captures some of the strangeness of being a teenager discovering the world. It's called "How to Talk to Girls at Parties," and it's really only one scene: Two boys stumble upon a party where the girls seem rather alien. As it turns out, the girls are actual aliens.

For decades, Americans have seen celebrities through photographer Mark Seliger's lens. His work has appeared in magazines such as Vanity Fair, GQ and Rolling Stone.

"Having a sense of humor" is important to the work, he says. "Whether it's a big concept or whether it's a wink."

Last week, teachers-to-be WinnieHope Mamboleo and Cristina Chase Lane marched across the graduation stage at North Carolina State University.

This week, they'll be marching with future colleagues at the state capitol in Raleigh, asking for better pay and better school funding.

North Carolina is the sixth state to see teacher walkouts in the past four months. The others are West Virginia, Oklahoma, Kentucky, Colorado and Arizona. The Tar Heel state ranks 39th both in per-student spending and in average teacher pay as of 2017.

The new movie "Beast" is a psychological thriller set on a quaint island in the English Channel called Jersey. Twenty-seven-year-old Moll lives a quiet, stifling life with her controlling mother.

At any given moment, volunteers and paid workers are writing fictional narratives that they present online as news stories, and some of those will get picked up and shared — perhaps thousands of times — on social media.

Hoaxes are presented as fact, conspiracy theories are offered as truth, and some of them may even end up on Wikipedia, one of the most-visited sites online.

University of Michigan students Griffin St. Onge and Lauren Schandevel have published an online guide that anybody can edit called "Being Not Rich at UM." It's a Google Doc about navigating the costs of college that has grown to more than 80 pages.

Allan Monga, a junior at Deering High School in Portland, Maine, traveled to Washington, D.C. to compete in the Poetry Out Loud contest on Monday. It's a national competition in which students recite great works of poetry, and it's run by the National Endowment for the Arts and the Poetry Foundation.

But Monga, who says he fled violence in his home country of Zambia, was initially barred from the national final because of his immigration status: He's an asylum seeker and does not yet have U.S. citizenship.

Killer robots have been a staple of TV and movies for decades, from Westworld to The Terminator series. But in the real world, killer robots are officially known as "autonomous weapons."

At the Pentagon, Paul Scharre helped create the U.S. policy for such weapons. In his new book, Army of None: Autonomous Weapons and the Future of War, Scharre discusses the state of these weapons today.
