In theory, three-dimensional video heightens the emotional impact of a movie scene — imagine if that guy from My Bloody Valentine appeared to be swinging his pickaxe straight at you, or if The Polar Express swooped out of the screen and just narrowly avoided running over your popcorn.
Pretty exciting, huh? Perhaps, but psychologists — who are a bit more even-tempered about the latest technology and a bit less interested in your wallet, compared with movie producers — say otherwise in a recent study.
Though movie makers might well take note, Daniel Bride, Sheila Crowell, and...
MoreMIT researchers have released a video of a robot they're calling "cheetah" making its way across campus. An earlier robot that was also called cheetah was part of a DARPA/Boston Dynamics (now owned by Google) collaboration that was notable for its speed. The MIT version is notable for ditching the tethers that supplied power to it—it goes for runs using on-board battery power and control logic.
Cheetah is only able to move at up to 10 mph, but its developers expect that they'll be able to get it to eventually travel at up to 30 miles an hour. For now, cheetah's biggest accomplishment is being able to move without any wires, which are normally used to supply power, and in some cases command-and-control, to more sophisticated robots.
The MIT group has also been working on the mechanics of the robot's stride, trying to have it exert more force each time it strikes the ground. The result is that it's been able to move across less rigid surfaces, like grass, which is why it's able to be taken out onto the MIT campus. Additionally, they've developed a routine that allows the robot to take a hop, which will let it bound over obstacles.

According to the traditional theory of nerves, two nerve impulses sent from opposite ends of a nerve annihilate

Taken from an Atlantic beach, Cape Canaveral, planet Earth, four identically framed digital images are combined in this night skyscape. Slightly shifted short star trails dot the sky, but the exposure times were adjusted to follow the flight of a Falcon 9 rocket. The September 21 launch delivered a Dragon X capsule filled with supplies to the International Space Station. Above the bright flare seen just after launch, the rocket's first stage firing trails upward from the left. After separation, the second stage burn begins near center with the vehicle climbing toward low Earth orbit. At the horizon, the flare near center records the re-ignition and controlled descent of the Falcon 9's first stage to a soft splashdown off the coast.
