The White House gets a new Internet-security division

On the eve of Election Day, Americans are busy debating the issues, everything from health care and the economy to the war in Iraq and global warming. But there's a vital issue few citizens or politicians seem to be talking much about, though they should be: cyber-security.

Good morning, Senator (or should I say "President-elect"?), and congratulations. You talked during your campaign about using the Internet to engage with regular folks, and surely you did. So did your opponent. The last time I checked, the two of you had amassed about two million friends between you on Facebook and MySpace, and another few hundred thousand followers on Twitter and YouTube.
Using motion sensors, brain signals and a heap of creativity, several new technologies promise to do away with cramped typing fingers, videogame-fried eyes and hoarse phone voices. This past summer in Tokyo, for instance, a paralyzed man with electrodes attached to his head took his Second Life avatar on a virtual walk just by envisioning his character strolling.
We compare three high-definition compact cameras to see which
captures the most cinematic footage

New point-and-shoot cameras capture video in the 720p high-def format you've seen on TV networks such as ESPN. But all HD is not equal. The algorithm, or codec, that compresses the video onto a memory card affects the quality of the footage and your ability to edit it. We tried out three cameras, each sporting a different codec, to find the best mobile movie rig.
This ski stretches wide for easy turns and shrinks for downhill speed

The Atomic D2 Vario Cut is like two skis in one: It's straight and narrow for zooming downhill but expands to be wider at the tip and tail when you turn -- creating a curved ski that, like a sharply turned car wheel, carves through a tight arc.
When he was 12, John Santini's ankle swelled up to the size of a grapefruit. Several hospital visits later, he was diagnosed with lupus, a chronic disease marked by the immune system's attacks on healthy parts of the body. He learned he'd have to take medication indefinitely. But he has used his condition as inspiration, and has spent his life devising a completely new way to deliver drugs.
"Here's what happens when we turn on the light," Karl Deisseroth says. He points to a mouse, ordinary save for the thin optical fiber protruding through its skull. When a lab tech presses a lever, blue light shoots through the fiber, and the mouse -- which had been sauntering straight ahead -- starts to run in circles. "He's doing that because the blue light turns the neural circuit on," Deisseroth explains. "As soon as we stop the stimulation, he'll walk straight again."
Imagine a car veering off a lonely mountain road and tumbling down the embankment. Minutes later, a sleek aircraft zooms in quietly at 230 miles an hour, tilts its wings and rotors up, hovers, and sets down just feet from the wreck. The pilot and a medic load the injured driver into the aircraft and zip back to a hospital at twice the speed of a conventional helicopter ambulance.
Using an infrared filter blocks visible light, yielding a trippy effect.
Infrared photography, which blocks visible light and captures only the IR spectrum to produce strange, beautiful images like the one above, has been around for more than a century. But it's become more popular recently, since now anyone with a point-and-shoot camera can easily take these unusual shots. Not all subjects are suitable—some objects reflect part of the infrared spectrum, making them appear white and almost ghostly, so you won't want to shoot, say, candid family shots. When done right, however, IR can work wonders. Formal portraits, for example, gain a delicate touch. Because IR softens the image, your subject's skin will be imbued with a smooth glow that effectively hides blemishes and wrinkles. Landscapes, too, take on an ethereal look.
We’re not sure which is scarier, getting lost in the woods or being rescued by a swarm of mini robotic grasshoppers. But it’s search-and-rescue situations that a Swiss robotics lab had in mind when they built the world’s smallest hopping robot.
