                                    some of the most advanced human-computer interaction 
                                    technology with one of the oldest forms of 
                                    entertainment -- puppetry -- and you get a 
                                    literal embodiment of a computer interface. 
                                    Meet Horatio Doc Beardsley, forerunner of 
                                    a future generation of personal assistants, 
                                    electronic pets, robotic waiters and salespeople 
                                    and animated historical museum figures. Full

                              cascade broadens laser Picture a flash of light every time a marble hits 
                              a step as it bounces down a set of stairs. Make 
                              each flash a slightly different color and you have 
                              a rough idea of how a new kind of laser works.
 
 Biology 
                              harbors hidden complexity
 Artificial systems do simple things and are made 
                              of simple components. They are also held together 
                              by complicated networks that remain behind the scenes 
                              until things go horribly wrong. The same is true 
                              for living beings.
 
 Heat 
                              engines gain quantum afterburner
 Thanks to some nifty quantum physics, the hot gases 
                              produced by internal combustion engines could be 
                              used to drive lasers.
 
 Nanotubes 
                              branch out
 Carbon nanotubes, those versatile, microscopic, 
                              rolled-up sheets of graphite, have already been 
                              made in Y and T shapes. A new process grows them 
                              in an intricate web of branches and junctions, opening 
                              new possibilities for making electronics, sensors 
                              and filters.
