Don't believe everything you hear -- a new science app reminds iPad users that our brains like to play tricks on us.

Created by the Exploratorium museum, Sound Uncovered replicates sound phenomena experiments, using examples that test what you thought you knew -- like why we can hear our car engines -- and introduces some sounds you may have never heard before.

"It's revealing the kink in the system, how your brain works," said Jean Cheng, project director of the online engagement group for the Exploratorium. The app's creators -- a mix of scientists and … Read more

Since 1977, there's been "Star Trek" and there's been "Star Wars" and never the twain shall meet.

It's not that fans of one franchise couldn't be fans of the other. But for the most part, if you were involved in the production of one, you weren't involved in the other. But now, with word out of Hollywood that "Star Trek" and "Star Trek Into Darkness" director J.J. Abrams may helm the forthcoming "Star Wars Episode VII," we may have an unprecedented mixing of the … Read more

Led by Entrepreneur magazine's entrepreneur of the year Limor Fried, Adafruit has a long history of promoting the do-it-yourself movement, and giving those who play and work in it the tools they need. … Read more

LAS VEGAS--When you come to CES here, you expect to see computers and TVs galore. Mobile phones, sure. Printer and speakers? Check. But a 50-foot-long mechanical snake?

Though we're in an arid, desert-like Nevada environment (never mind all the cement and golf courses), this isn't Burning Man. But sure enough, just behind the CNET trailer here, Titanoboa is strutting its stuff. And indeed, Titanoboa is a 50-foot mechanical snake.

Created by EatArt, the Vancouver arts collective, Titanoboa seeks to invoke the promise -- or the threat -- of global climate change, and the kinds of things we might start to see happen on this wonderful planet of ours. According to the Titanoboa project page: … Read more

NASA might not agree, but plenty of folks seems to think the apocalypse is imminent. Whether it happens this Friday or decades from now, it's never too early to start preparing.

With that in mind, I scoured the CNET archives and watched hours of "The Walking Dead," "Falling Skies," "Revolution," "Wolf's Rain," "Red Dwarf," and dozens of other series to come up with this gallery of essential pieces of gear to start investing in now, while you still can.… Read more

PETALUMA, Calif.--Driving along the back roads of this idyllic, easy-going Northern California town, you'd never know that behind the walls of one of the most unassuming buildings around is perhaps the best collection of geek memorabilia in the world.

Welcome to Rancho Obi-Wan, Steve Sansweet's homage to his life's passion -- "Star Wars," a non-profit museum dedicated to serving "the public through the collection, conservation, exhibition and interpretation of [the films'] memorabilia and artifacts." Formerly Lucasfilm's head of fan relations and a Los Angeles-based reporter for the Wall Street Journal, Sansweet … Read more

Since September 11, 2001, the American security apparatus has been focused largely on stopping terrorists from striking again. But some feel a more pressing danger may be that of cyber attacks, digital hacks that disable critical infrastructure and bring society to a crawl.

As the U.S. government has tried to shape its approach to such attacks, President Obama and the secretary of defense have relied on contributions from a number of people in the Pentagon and elsewhere for ideas on how to stop bad actors, be they from national governments or small terrorist groups. Among them was Assistant Secretary … Read more

After a record-breaking 9,000-mile journey across the ocean, a small autonomous robot recently arrived in Australia having collected and transmitted a wealth of scientific data that could lead to a better understanding of the world's seas.

On November 17, 2011, a Silicon Valley startup called Liquid Robotics launched four of its Wave Glider robots from San Francisco, two of which were heading toward Australia and the other two on their way to Japan. The hope was that the Wave Gliders, which are designed to travel across the globe without fuel or outside propulsion, would set the Guinness World … Read more

It's easy to pamper your pet with some table scraps, a few extra treats, and a little too much dog food. Before long, your fit Fido has become a hefty hound. Fujitsu is looking to help dog owners fight the fat with a pedometer and cloud service system.

The Wandant pedometer is based on motion-tracking technology from Fujitsu Laboratories. It measures and records the steps your pooch takes, picks up shivering motions, and monitors temperature changes.

All that data gets uploaded to an accompanying cloud service so you can view graphs and reports on your dog's activities.… Read more
