A novel three-dimensional (3-D) touchless interactive display can change color based on the distance of the user's finger from the screen by detecting subtle shifts in ambient relative humidity, according to a new study. ...
MIT researchers have developed a process to manufacture and integrate "artificial atoms," created by atomic-scale defects in microscopically thin slices of diamond, with photonic circuitry, producing the largest quantum chip ...
