Researchers have managed to cool a miniature mechanical object to its lowest possible energy state using laser light. The achievement paves the way for the development of exquisitely sensitive detectors as well as for quantum experiments that scientists have long dreamed of conducting.
An experiment published in the 28 September issue of Nature in which rats are "teleported" shows how memory is organized into discrete 125 millisecond-long packets, enabling a smooth transition between one memory and the next.
Researchers have demonstrated that electrons can move freely in layers of linked semiconductor nanoparticles under the influence of light. This new knowledge will be very useful for the development of cheap and efficient quantum dot solar cells.
