With more than 2 billion monthly active users, Facebook can keep tabs on nearly a third of the world's population. Whether you visit the social network daily (as 1.32 billion people do) or only log on to RSVP to events, you should be aware of how much of your personal data you're giving to the site, and the company behind it.
A ridesharing service like Uber or Lyft seems like it should help stem drunk driving by offering an easy, cheap option for tipsy customers to get home at the end of the night. And Uber even claims on its website that ride-hailing options like it “are helping to curb drunk driving.” But new research shows that Uber's presence in a city only inconsistently leads to a decline in accidents caused by intoxication behind the wheel, and there's far from being a conclusive answer to the question.
In 1908, five years after the Wright Brothers first flight at Kitty Hawk, U.S. Army Lieutenant Thomas Etholen Selfridge earned the dubious distinction as the first person to die in an airplane crash. In fact, the early years of aviation are littered with bodies. Last week, a pair of brothers in Washington state debuted an aircraft they see as the answer to the long-sought dream of perfectly safe flight. With a rigid, winged body held underneath a massive helium-containing envelope, their craft is billed as a fusion of both airplane and blimp technology. It is called “Plimp.”
Have you heard? Siri, the virtual persona that speaks from your iPhone, sounds different now. The new voice officially rolls out today as a part of Apple's latest mobile operating system, iOS 11. Her new pipes make her sound higher in pitch and younger. She's perkier and more personable. Most important, she sounds more human.
Over the weekend, North Korea unveiled a new weapon. It is small, maybe small enough to fit in the nose cone of a missile. It is powerful, detonating with the force of possibly 140 kilotons, or almost 10 times the destructive power as “Little Boy,” the bomb dropped on Hiroshima in 1945. This thermonuclear warhead is shiny, bare metal like the naked skins of the early jets that first fought in the skies above Korea almost 67 years ago.
At about 6am on local time Tuesday morning, Japan's government issued a warning to its citizens that a missile was headed their way. That missile, fired from North Korea, crashed into the Pacific Ocean 575 miles east of Japan just 14 minutes after launch. This test was the third time that North Korea's ever successfully launched an object over Japan, and the first time that the object in question was explicitly a missile.
In the future, your workout—or your workout gear, to be precise—might generate enough energy to charge your activity tracker. Researchers from the University of Texas at Dallas and South Korea's Hanyang University (among other institutions) have figured out that by twisting carbon nanotubes into yarn, forming what they call a “twistron harvester,” they can harness mechanical energy and turn it into electricity. They published their results this week in the journal Science.
