A "superbug" outbreak suspected in the deaths of two Los Angeles hospital patients is raising disturbing questions about the design of a hard-to-clean medical instrument used on more than half a million people in the U.S. every year.

At least seven people — two of whom died — have been infected with a potentially lethal, antibiotic-resistant strain of bacteria after undergoing endoscopic procedures at Ronald Reagan UCLA Medical Center between October and January. More than 170 other patients may also have been exposed, hospital officials said.

If you've recently purchased a laptop computer made by Lenovo, you may want to hear this: Experts say the world's biggest computer maker shipped laptops with pre-installed software that could let hackers steal passwords or other sensitive information when you use the web to shop, pay bills or check email.

Lenovo said Thursday that it has disabled the offending software, known as Superfish, and will provide customers with a tool that permanently removes the program from their computers. The company initially said its own investigation didn't find "any evidence to substantiate security concerns." But it later removed that sentence from a statement on its website.

Officials in India want to make one thing clear: The tree that President Barack Obama planted here three weeks ago is not dead.

It just looks dead.

A ceramic clown that went missing from a closed Wichita amusement park more than a decade ago has been found at the home of a sex offender who once worked at the park and two decades ago helped restore the clown.

The return of Louie the Clown, the mascot of the Joyland amusement park, was announced during a media briefing Thursday.

The Oscar-nominated film "The Imitation Game" may fudge some of the facts and amp up the drama to appeal to Hollywood audiences, but there's still a lot the film gets right about the Allied effort to crack the German armed forces' sophisticated communications code during World War II, says the owner of one of America's largest collections of Enigma encryption machines used by the Nazis.

Kenneth Rendell, a historian and collector who operates the Museum of World War II, says the movie's biggest achievements are introducing the critical wartime contributions of pioneering British mathematician and computer scientist Alan Turing to new audiences and showcasing the legendary complexity of the Nazi code machines, which were used for nearly every level of military communication, from the mundane to the top secret.

Earth's past, present and future come together here on the northern peninsula of Antarctica, the wildest, most desolate and mysterious of its continents.

Clues to answering humanity's most basic questions are locked in this continental freezer the size of the United States and half of Canada: Where did we come from? Are we alone in the universe? What's the fate of our warming planet?

Strap on the Samsung Gear S or the Sony SmartWatch 3 if you want to take a jog on the beach or head out for a bike ride without your phone clunking along.

One of my frustrations with early smartwatches has been how little they can do on their own. Sure, your phone might be with you most of the time, but sometimes you want to leave it behind. The Gear S and SmartWatch 3 still need to be close to an Android phone for a lot of things, but both do more solo than other smartwatches.

Cuba has temporarily reduced the hourly charge for using state-run Internet cafes in the country's first small but substantive public move to increase online access since the declaration of detente with the U.S.

President Barack Obama said late last year that Cuba had promised to increase Internet access, although U.S. and Cuban officials have since provided few specifics.

A San Francisco taxi company is ditching its 82-year-old brand and renaming itself after a smartphone app in the latest sign of how mobile technology is changing the way people get a ride.

The transformation dumps DeSoto Cab's Depression-era identity in favor of Flywheel, an app that helps traditional taxis compete against increasingly popular ride-hailing services such as Uber and Lyft.

A black man who was blocked from boarding a Paris metro train by Chelsea football fans chanting racist slogans wants the group to be "found, punished and locked up."

In an interview with Le Parisien newspaper, the man — identified only as Souleymane S. — said he had lost his phone in the scuffle in the metro and didn't learn until Wednesday evening that the altercation was filmed. Because he doesn't speak English, he said he didn't fully grasp what the rowdy group was saying — they chanted "we're racist, we're racist, and that's the way we like it" — but their meaning was clear.
