When you think of the giant tire manufacturers, names like Goodyear, Firestone, and BFGoodrich probably come to mind. So it might surprise you to learn that the largest maker of tires on the planet is none other than the most famous toy company in the world: Lego.

To be sure, Lego's tires are not all-weather, nor can they go off-road. They also fit in the palm of your hand. But for 50 years, Lego has been churning out its little wheels, millions per year, topping out at an unbelievable 381 million in 2011, the company said.

This tire empire … Read more

Did famed filmmaker James Cameron just do for the oceans what scientific experts have struggled to do for decades?

When "Avatar" and "Titanic" director Cameron piloted his custom submersible, the Deepsea Challenger, to the bottom of the Mariana Trench yesterday and became the first person ever to make a solo dive to the world's deepest spot, he shined a crucial spotlight on the field of ocean exploration.

In recent years, scientists have been shouting from rooftops around the world that unless humanity puts more energy into studying our oceans, we are at real risk of … Read more

Everyone likes a good paper airplane. But how much do you love a 45-foot paper airplane?

The answer is clear: A lot.

And your love doesn't have to be unrequited, because the good folks at the Pima Air and Space Museum in Tucson, Ariz., have not only built but also flown a 45-footer, achieving the feat earlier this week. (See video below.)

"It's not every day that a giant paper airplane is released high over the Arizona desert. In fact, it's never been done. But that's exactly what the Pima Air and Space Museum did,&… Read more

For years, Adam Savage and Jamie Hyneman were known for one thing: being the "MythBusters."

But now, the two have launched a new show, Discovery Channel's "Unchained Reaction," "a new six-part series that pits two teams of varying backgrounds against each other to build an elaborate chain-reaction contraption."

Think giant Rube Goldberg machines--balls falling and knocking things into other things. Seesaws going up and throwing things into the air, each step in the process impacting the next, with each team vying to build the most impressive contraption in five tension-packed days. The … Read more

IBM said this evening that its scientists have developed a computer chip that can move a trillion bits of information a second.

Known as the "Holey Optochip," the prototype optical chipset can transfer the equivalent of 500 high-definition movies a second, or the entire U.S. Library of Congress Web archive in an hour, Big Blue said. The innovation is possible because IBM's scientists figured out that, by drilling 48 minuscule holes in a standard quarter-inch silicon CMOS chip, they were able to ramp up data transfer rates from what was possible.

And by breaking through the … Read more

If you were ever a Boy Scout, you may recall earning an archery or camping badge. Girl Scouts offer athlete, naturalist, and many others. But what if you're a kid with serious 3D printing or laser cutting chops? Is there a badge for you?

There is now, thanks to the folks at Adafruit Industries, a New York-based open source hardware and maker products emporium. Starting in the next few days--timed to the 100th anniversary of the Girl Scouts on March 12--Adafruit will begin offering a broad set of skill badges that reward kids--and presumably others--for completing any of a … Read more

The U.S. Navy says it has tested one of two prototypes of its futuristic electromagnetic railgun, a weapon that could fire a 5-inch projectile up to 100 miles, yet which requires no explosives to fire.

The Office of Naval Research is evaluating competing railguns--one from BAE Systems, and one from General Atomics. Yesterday, ONR announced it has completed a successful test of BAE's model, and the Navy is expected to test-fire General Atomics' offering sometime in April.

"The firing at Naval Surface Warfare Center Dahlgren Division...kicks off a two-month-ling test series by [ONR] to evaluate the … Read more

A management swap at the top of Boeing's much-hyped 787 Dreamliner program is shining a spotlight on the airline industry's frustration at the slow pace of deliveries of the fuel-efficient and technically advanced plane.

Today, Boeing said that it's shuffling the leadership of the Dreamliner and 777 programs, with Larry Loftis, formerly vice president and general manager of the 777 program, moving into the Dreamliner program's top position. At the same time, Scott Fancher, formerly the VP and GM of the 787 program, is now taking over the 777 efforts.

While Boeing neither characterized the switch … Read more

With just 2 percent of the Smithsonian's archive of 137 million items available to the public at any one time, an effort is under way at the world's largest museum and research institution to adopt 3D tools to expand its reach around the country.

CNET has learned that the Smithsonian has a new initiative to create a series of 3D-printed models, exhibits, and scientific replicas--as well as to generate a new digital archive of 3D models of many of the physical objects in its collection.

Representative of that effort, the museum is touting the 3D printed replica of … Read more
