MakerBot, one of the most well-known desktop 3D printing companies, has been acquired by Stratasys, the companies said Wednesday.

In a release, the companies said it was a stock-for-stock transaction worth about $403 million, based on Stratasys' stock price as of Wednesday. Stratasys will exchange 4.76 million shares of its stock for 100 percent of MakerBot's outstanding stock. By agreeing to be acquired, MakerBot becomes part of one of the leading industrial 3D printing companies. The deal also allows the publicly-traded Stratasys to compete more directly at the consumer level with 3D Systems and that company's Cube … Read more

Nvidia, trying to move its graphics chips into the supercomputing market, has found a niche helping engineers build brain-like systems called neural networks.

For years, the company has advocated the idea of offloading processing tasks from general-purposes central processing units (CPUs) to its own graphics processing units (GPUs). That approach has won over some researchers and companies involved with neural networks, which reproduce some of the electrical behavior of real-world nerve cells inside a computer.

Neurons in the real world work by sending electrical signals around the brain, but much of the actual functioning of the brain remains a mystery. … Read more

Performing more than 33 quadrillion calculations per second, a new Chinese supercomputer called Tianhe-2 arrived two years earlier than expected to claim the top spot in a list of the 500 most powerful supercomputers in the world.

The Top500 list, updated twice a year at the International Supercomputing Conference, measures performance for mammoth systems typically used for jobs like modeling nuclear weapons explosions and forecasting global climate changes. And the Chinese machine, at the National University of Defense Technology, is more mammoth than most.

The Tianhe-2 has 32,000 Xeon processors boosted by 48,000 Xeon Phi accelerator processors for … Read more

Imagine a souped-up Google Glass built into a motorcycle or bicycle helmet that superimposes information and directions in front of your eyes as you speed down a highway or move through a congested downtown area.

LiveMap, a startup based in Moscow, is developing a motorcycle helmet with a head-mounted display, built-in navigation, and Siri-like voice recognition. The helmet will have a translucent, color display that's projected on the visor in the center of the field of vision, and a custom user interface, English language-only at launch, based on Android.

Unlike visor-mounted heads-up displays, which have been available for a … Read more

In another step toward 3D printers finding a place in everyday businesses and homes, online retailer Amazon has dedicated a section of its site to selling 3D printers.

The site sells 3D printers from well-known manufacturers such as Makerbot, as well as others such as Cubify and fabbster, alongside 3D printer filament and spare parts.

Prices for machines range from the $1,099 JET/Open Source 3D printer Replicator G to $2,479 MakerBot Replicator 2 Desktop 3D printer.

The section marks another move toward mainstream adoption for 3D printing and follows office-supply chain Staples' decision to begin stocking 3D printers.… Read more

Everybody knows we all need faster Web sites: speedy load times and responsive pages means that people stay on a site longer, look at more photos, see more ads, and buy more stuff. Much of the work to speed things up has happened in the browser, but a startup called Instart Logic hopes to profit by changing what happens on the server, too.

The Mountain View, Calif.-based company came out of stealth mode Thursday, describing how its technology works and touting customers including Game of Thrones Ascent, GameStop, Bonfaire, and Kitchit.

"We generally drop people's load time … Read more

Drawing from engineering ideas that are revamping personal computers, IBM and two Swiss universities are using flash memory to improve performance of a supercomputer designed to simulate an actual mouse brain.

But there's a lot more flash memory than you'll find in the latest laptop.

A PC's solid-state drive may come with something like 128GB to 512GB of flash memory. The mouse-brain project's specially upgraded version of a Blue Gene/Q supercomputer has 250 to 1,000 times as much flash memory -- 128 terabytes.

The supercomputer project, in conjunction with the Ecole Polytechnique Federale de … Read more

With its six Thunderbolt ports and a "unified thermal core," Apple's new Mac Pro doesn't just sound like a futuristic piece of alien machinery, it also looks like something out of science fiction.

Far from the boxy designs of early personal computers, the new Mac Pro is compact, sleek, and nearly edgeless. The resemblance of the Mac Pro, which is aimed squarely at creative pros, to a tiny nuclear reactor is in part due to that heat sucking "thermal core" design. Heat generated from the Intel Xeon CPU and new solid-state drive (SSD) storage dissipates out through the core as the hot air rises -- a change from the typical front-to-back system of air flow in most consumer desktops.… Read more

SANTA CLARA, Calif. -- Reality isn't what is used to be. With increasingly powerful technologies, the human universe is being reimagined way beyond Google Glass' photo-tapping and info cards floating in space above your eye. The future is fashionable eyewear, contact lenses or even bionic eyes with immersive 3D displays, conjuring up a digital layer to "augment" reality, enabling entire new classes of applications and user experiences.

Like most technologies that eventually reach a mass market, augmented reality, or AR, has been gestating in university labs, as well as small companies focused on gaming and vertical applications, … Read more
