                                    matter how big the Internet grows, it's likely 
                                    to remain a small world -- at least in terms 
                                    of how many hops it takes to get from one 
                                    point to another. A study shows that the structure 
                                    of the Internet means you'll never be all 
                                    that far from anything on the Net. Full

                              automate computer sharing Grid and peer-to-peer computing could turn computer 
                              processor time and disk space into commodities available 
                              by the hour. First, someone has to figure out how 
                              to keep track of who has what available when, who 
                              used what for how long, and how much it all cost.
 
 Nanotube 
                              kinks control current
 Put a couple of well-placed kinks in a vanishingly 
                              small carbon nanotube and you have a transistor 
                              that controls the flow of electricity one electron 
                              at a time. The bent tubes could be building blocks 
                              for superfast computers.
 
 Hydrogen 
                              chip to fuel handhelds
 Fuel cells will be the power source of the future 
                              if researchers can figure out how to generate hydrogen 
                              on the fly. A chip that pulls hydrogen out of a 
                              mixture of methanol and water could lead to longer-lasting 
                              portable devices.
 
 Scheme 
                              harnesses Internet handshakes
 Imagine if every time you shook somebody's hand 
                              you could secretly exploit their muscle movement, 
                              getting them to unwittingly contribute a little 
                              manual labor to the task of your choice.
