Like a traditional hard drive, a flash-based drive stores information in the computer-readable language of 0s and 1s. But instead of writing data by flipping magnetic poles on a spinning disk, flash memory just shuttles electrons around on a stamp-size microchip.

When the GeoEye-1 surveillance satellite comes online this spring, its advanced optics will produce more-detailed images than any commercial satellite, capturing objects as small as home plate on a baseball diamond and filling in the fuzzy spots on Google Earth.

Creating a laser that can melt a soda can in a lab is a finicky enough task. Later this year, scientists will put a 40,000-pound chemical laser in the belly of a gunship flying at 300 mph and take aim at targets as far away as five miles. And we’re not talking aluminum cans. Boeing’s new Advanced Tactical Laser will cook trucks, tanks, radio stations—the kinds of things hit with missiles and rockets today. Whereas conventional projectiles can lose sight of their target and be shot down or deflected, the ATL moves at the speed of light and can strike several targets in rapid succession.

As cameras continue to shrink in size and weight, an often overlooked side effect is their lack of image stability. Naturally, the heavier the camera, the less your shaky hands move its lens. Via optical image stabilization, the Panasonic HDC-SD5 keeps footage rock solid while maintaining a pocket-size form factor.

Pop this pill, and eight hours later, doctors can examine a high-resolution video of your intestines for tumors and other problems, thanks to a new spinning camera that captures images in 360 degrees. Developed by the Japanese RF System Lab, the Sayaka endoscope capsule enters clinical trials in the U.S. this month.

In a “high-bypass” turbofan engine like the GEnx, 90 percent of the thrust comes from spinning fan blades in front that draw in massive quantities of air and force it out in a ring around the engine’s center, or core. The GEnx’s primary innovation is in its fan blades, which have been reshaped to move air more efficiently with fewer blades and are made of carbon fiber to save weight.

Four years in the making, Pleo, from California start-up Ugobe, is a baby dinosaur robot that acts and learns like a real animal, remembering traumatic experiences and friendly owners. We peeled off its skin to reveal more than a dozen motors, six processors and 38 sensors behind its personality.

The ReCharge, Volvo’s concept plug-in hybrid, could squeeze 160 miles from a gallon of gas by tossing out the power-wasting transmission. It packs a small electric motor inside each wheel, so that no power is lost in the drivetrain. Here’s a look at the next generation of fuel-efficiency
