Republicans are hopeful about avoiding another special election upset in Arizona on Tuesday.

The race in the conservative 8th Congressional District northwest of Phoenix is being looked at closely, after special election shockers in recent months in Pennsylvania and Alabama, where Democrats won a House seat and a Senate seat, respectively, in territory where Republicans had been in control for years.

The race is between Republican Debbie Lesko, a former state senator, and Democrat Hiral Tipirneni, a physician new to politics.

In a rare joint statement, the U.S and U.K. last week warned that Russia is actively preparing for a future cyberwar against the West.

Volkswagen is trying yet again to turn the page after its emissions cheating scandal — leaving diesel behind in favor of electric cars.

The major shift comes as the German automaker — the world's largest in term of cars sold — has a new leader in Herbert Diess.

Iran's Foreign Minister Mohammad Javad Zarif tells NPR that renegotiating the 2015 nuclear deal between his country and six world powers would be opening a "Pandora's box" that risks damaging U.S. credibility in future international talks.

Jurors in Arizona found U.S. Border Patrol agent Lonnie Swartz not guilty of second-degree murder in a fatal through-the-fence shooting of a teenager from Mexico, but they deadlocked on a lesser charge of manslaughter.

U.S. District Judge Raner Collins declared a mistrial, meaning that Swartz, 43, could be retried for the 2012 death of 16-year-old Antonio Elena Rodriguez of Nogales, Mexico, who was among a group throwing rocks at border agents during an attempt to smuggle drugs into the U.S.

From San Francisco to Washington, D.C., e-scooters and dockless bikes have become the latest transportation trend to grip urban spaces — and local governments are struggling to keep up.

The concept is simple: Riders download an app, find and unlock a scooter or bike, and leave it when they're done. Many cost as little as $1, and fans of the services tout them as faster, easier, and greener ways to get where they're going.

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.

A team of surgeons says it has repaired the genitals of a serviceman severely injured by an explosion in Afghanistan. It's the first time a penis has been transplanted to treat a war wound.

Doctors at Johns Hopkins Hospital in Baltimore say 11 surgeons were involved in the 14-hour surgery in March.

Barkatullah is 13. He lost his right arm and leg in a mine explosion on May 2017. But that does not deter him from dreaming of a brighter future. "The policemen were among the people who rescued me and saved my life," he says on a chilly evening in the children's playground at the Emergency War and Trauma Hospital in Kabul. "That is what I want to do when I grow up."
