The world is generally not kind to long-belated sequels. Or perhaps it would be more accurate to say that long-belated sequels are generally not kind to the world. When a film property sits on the shelf long enough, its recipe fades and its ingredients molder. Thus The Godfather: Part III. Thus The Two Jakes. Thus Indiana Jones and the Aliens George Lucas Insisted On Putting In. (Yes, yes, Toy... more.

First came the water-powered jetpack. Next came the water-powered jetboots. And now, we have the water-powered jetbike. It's Jetaviation's Jetovator, and they want you to "turn off the video games…Saddle up…and Ride the Hose!" So, go on, ride the hose. Ride it. RIDE IT. In order to ride the hose on the Jetovator, you'll need your own personal watercraft (Seadoo, Yamaha or Kawasaki),... more.

A few years ago, a 10 million watt wind turbine was built in Norway. Now, heading in the complete opposite direction, Scotland installed a 100-foot 1-megawatt turbine under water, off the coast of Orkney. Scottish Power Renewables is overseeing the project, and the reports show the turbine is performing well, already providing power for the island of Eday. It's part of the creation o... more.

Voyager 1 departing our solar system — lest it smash into an asteroid or run afoul of a black hole, say — is seen as an eventuality, though we've waited a while. Now, NASA's Jet Propulsion Laboratory, based on data sent by the craft, is saying the explorer could become the first manmade interstellar object very soon. NASA launched two identical Voyager probes in 1977: Voyager 2 went ... more.

When I was 13, I was sent to the optician for the first time, and came home with glasses. Suddenly, the world was sharp all around me. I was surprised by the crisp lines of the tree branches against the sky. It was news to me that I was near-sighted, because I had been used to seeing the world in a blur. Apple Inc. sells a similar epiphany, starting this week, in the shape of a notebook co... more.

With its stock value sinking, Facebook is looking to restore faith in its ad-based business model any way it can. It’s solution? A form of ad auctioning known as real-time bidding. With the new system, dubbed “Facebook Exchange”, advertisers will be able to display more targeted ads using the browsing history of individual Facebook users, Bloomberg reports.

Do you remember the first time you saw “Alien”? Of course you do. You remember that marvelously constructed ship, that understated score, that terrible, consuming sense of foreboding, which builds and builds relentlessly until it (quite literally) explodes and careens out of control. It was like nothing you had ever seen before. It was cold and unpleasant but contained just enough B-mo... more.

As you're about to see, it's a pretty good time to be both a fan of video games and science fiction. It's true that the two have always gone hand-in-hand, but at E3 2012 this year, we were treated to plenty of sci-fi goodness from familiar franchises and original ideas alike. Here we've collected all the games announced at the show that have a sci-fi angle. We've picked a few of our favorite... more.

Plasma thrusters may very well be the future of space propulsion. They're small, light, reliable, highly efficient, and are mostly powered by electricity. They do also need reaction mass to function, and researchers at the Australian National University have developed a new plasma thruster that runs on almost anything, including astronaut pee. ANU's helicon double layer plasma thruster ... more.
