Rice University scientists have created a rubbery, shape-shifting material that morphs from one sophisticated form to another on demand.  Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences, together with collaborators from the Fu Foundation School of Engineering and Applied Science at Columbia University, have developed a system to convert one wavelength of light into another without the need to phase match.  Light, which travels at a speed of 300,000 km/sec in a vacuum, can be slowed down and even stopped completely by methods that involve trapping the light inside crystals or ultracold clouds of atoms.  A research team led by physicists at LMU Munich reports a significant advance in laser-driven particle acceleration.
