stays small world
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.
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.
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.
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
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.
