- toward the light, away from the light and circling and spiraling motions.

What has the researchers excited is that the experiments established two-directional communication between the brain stem and the robot. The commands generated by the brain stem create movement in the robot; the movement, in turn, causes a change in the input from the optical sensors passed to the brain stem since the intensity of the input depends on the robots location with respect to a light source.

Mussa-Ivaldi said the research shows great promise for helping those who suffer from Parkinsons disease and stroke victims.

Shanghai Considers 300 Story Skyscraper<\b>

SHANGHAI, China - Officials in this Chinese port city are discussing plans to build a 3,700-foot skyscraper capable of housing 100,000 people, according to the Sunday Times.

A team of architects from Spain will design the building, which resembles a giant cigar. The tower would contain 12 open levels, and each level would contain 25 floors of mixed housing, hotels, office space and parks. The levels would be separated by sealed sections that would act like fire doors, the architects told the Times.

Plans for the foundation of the tower incorporate a root-like system that would sink into the Earth to a depth of 656 feet, the architects said. The spines of the foundation would spread outward, akin to an upside-down umbrella.

In addition, the towers 3,000-foot wide, wheel-shaped concrete base would rise out of an artificial lake that the architects told the newspaper would absorb vibrations from geologic tremors.

The outer shell of the tower would be a membrane comprised of glass and aluminum, perforated with openings along concourses to allow fresh air into the building - residents would be banned from opening the windows of their apartments.

According to the Times, the tower would be the worlds tallest building, easily dwarfing Kuala Lumpurs Petronas Towers, a scant 1,483 feet tall.
