...case of the flight circuits," he says, "it is like pushing a swing. One initial kick and it keeps swinging back and forth for a while."...Octopuses occasionally stroll around on two arms, UC Berkeley biologists report
... Normally, it crawls over the bottom of the ocean, pushing and pulling with the suckers on its eight arms, or jets backwards through the water. All these movements are accomplished through muscles that squeeze and bend the fluid-filled arms and body.

...ll, themselves, rip electrons out of the molecule, pushing it back into its insulating state. This decrease of current with increasing voltage is called "negative differential resistance" (NDR) and it allows a useful device to be made with just two electrodes, not the three originally used.

...nd thus be unable to change gears in time to avoid pushing the wrong button. They then adjusted the delay time over many trials so that each participant eventually exhibited error rates of about 50 percent when provided with an initial blue priming dash, compared with error rates of only 4 percent when prese...Spit, and call me in the morning
...alants. Other researchers are also focused on the pushing the technology forward. Daniel Malamud of the University of Pennsylvania is working on taking prototypes and turning them into diagnostic devices. He has just shown, as a "proof of principle," that it's possible to detect certain microbes - HIV and a......er Emergence of Homo sapiens Brown says that pushing the emergence of Homo sapiens from about 160,000 years ago back to about 195,000 years ago "is significant because the cultural aspects of humanity in most cases appear much later in the record only 50,000 years ago which would mean 150,000 years...The death of a very special chimpanzee

... installing GEOPS is almost as clean and simple as pushing a needle into an apple, Clark says. GEOPS' tough tip punctures the surface of the earth and slides easily through without disturbing the soil beneath or damaging its own parts. GEOPS' hull can take more than 50 g of acceleration and 30 tons of direct......e of this snapping can push the cilia bundle. Like pushing a child on a swing, successive pushes can build up to a large oscillation, amplifying the sound. In addition, different hair cells amplify different frequencies, so this mechanism could create the sharp tuning in the ear that allows us to discriminat...
