Cutting Edge

Stephen Hawking, one of the world's greatest physicists and cosmologists, is once again warning his fellow humans that our extinction is on the horizon unless we figure out a way to live in space.

Not known for conspiracy theories, Hawking's rationale is that the Earth is far too delicate a planet to continue to withstand the barrage of human battering.

"We must continue to go into space for humanity," Hawking said today, according to the Los Angeles Times. "We won't survive another 1,000 years without escaping our fragile planet."… Read more

Now that winter has passed, those of us who live in cold climes can once again appreciate the beauty of snowflakes without feeling the urge to curse them for making us dig out the shovel. And if ever snowflakes looked lovely, it's in these images shot by a high-speed camera system developed specifically to photograph them in 3D as they fell.

"Until our device, there was no good instrument for automatically photographing the shapes and sizes of snowflakes in free fall," says Tim Garrett, an associate professor of atmospheric sciences at the University of Utah and one of the developers of the cam known as MASC, or Multi-Angle Snowflake Camera. "We are photographing these snowflakes completely untouched by any device, as they exist naturally in the air."

MASC -- under development for three years -- takes 9- to 37-micron-resolution stereographic photographs of snowflakes from three angles while simultaneously measuring the speed of their fall, a highly influential factor in the location and lifetime of a storm. … Read more

Wednesday afternoon Google Ventures, Andreessen Horowitz and Kleiner Perkins Caufield & Byers, jointly announced plans to form an investment syndicate to supply seed money to startups developing products around Google's Glass and what it described as the "Glass ecosystem."

In comments the partners posted about the announcement on their respective websites, the participants gushed about the potential represented by Google Glass.

Marc Andreessen, general partner at Andreessen Horowitz, described the "thesis" represented by Google Glass as truly transformational.

"Instead of … Read more

It seems creativity knows no bounds when it comes to the Raspberry Pi. The $25 credit card-size computer has turned mixologist, powered an R2-D2 toy robot, and was even sent into near space.

Now, thanks to a group of National University of Singapore engineering undergraduates, the Raspberry Pi has also conquered water. Dubbed the Coconut Pi, the autonomous underwater vehicle (AUV) uses the Raspberry Pi for memory-intensive functions, while it relies on Arduino for precise control. … Read more

Turns out that crazy rumor was true: NASA is planning to capture an asteroid.

The plans were included in the space agency's $17.7 billion fiscal 2014 budget, part of the new $3.7 trillion government budget proposed earlier today by President Obama.

In the budgets, about $78 million is set aside for a plan that involves sending a craft to rendezvous with what's described as a "small asteroid," and then moving the space rock into a stable orbit near the moon. Astronauts will later visit the asteroid and scoop up samples for study back on … Read more

Segway scooters are still kind of cool, but they have the disadvantage of being big. It's a bit difficult to just pack one up, take it on your morning public transportation commute, and then saddle up to ride it to the office. Israeli designer Amir Zaid is thinking smaller than Segway when it comes to his all-electric MUV-e scooter. It's small enough to fold up into a suitcase-size bundle.

Zair's resume includes design work for Ferrari and Fiat, so you know the MUV-e isn't going to look like other scooters. It has three wheels and lots of rounded edges. There's even a bit of a Tron aesthetic at work here in looking at the renderings for the final product. Dare I say, it looks a little sporty? Not at all like this boxy scooter we saw recently.… Read more

There's no crying in baseball, and there's no crying in space.

While zero gravity doesn't have an impact on tears forming, it has an effect on if they fall -- and they don't. The water that builds up in your eyes from crying will stay there until the bubble gets so big it moves to another spot on your face, or it's removed. It's not very pretty or graceful.

Watch how Canadian astronaut Chris Hadfield -- commander of the International Space Station and maker of all sorts of entertaining space videos -- demonstrates what … Read more

Xerox has a different view on the future than most.

The company recently gave The New York Times the opportunity to see a new technology it's working on at its Palo Alto, Calif., research center. Referred to as Xerographic microassembly, the technology is based on the idea of laser printing and could one day become the most efficient way to bring circuitry to electronics products, Xerox claims.

According to the Times, Xerographic microassembly breaks traditional silicon wafers into thousands of "chiplets" and then bottles them up as a physical "ink." Once that ink is produced … Read more

The U.S. Navy is continuing its flirtation with laser weapons.

The latest tip-toeing move toward a more serious relationship came today with word from the Navy that it plans to deploy a solid-state laser weapon system aboard the USS Ponce in fiscal year 2014. Other than that, though, the announcement was absent any details about the capabilities of the particular laser weapon system or the expectations for its performance, though the Navy talked up the virtues of laser weapons in general as a countermeasure against threats including aerial drones and fast-moving small boats.

The Navy also described the deployment … Read more
