Growing Nanowires

Researchers have developed nanowire 'growing technology' which opens the door for faster, smaller microchips and lower power electronics. 3-D microchips, vertical stack of circuitry, is possible with this new discovery.

Altered Perception of Hands

The space within reach with our hands is named "action space". Research has shown that visual information in this area is organized in hand-centered coordinates, representation of objects in the human brain depends on their physical location with respect to the hand. New research shows that amputation of the hand results in distorted visuospatial perception.

Scans Show Learning 'Scripts' the Brain's Connections

Spontaneous brain activity formerly thought to be "white noise" is subject to change after an individual learns a new task. Scientists report that the degree of change reflects how well subjects have learned to perform the task. Even during sleep or anesthesia, the brain's spontaneous activity is not random, but organized patterns of correlated activity that occur in anatomically and functionally connected regions.
