Ties
that bind boost searches
Web communities are easy enough to recognize when
you come across them. But finding sites dedicated
to obscure subjects can be tricky. A method of mapping
related sets of pages could make for better search
engines.
Sapphire
chips linked by light
Sapphire is an electrical insulator and it's translucent.
Computer chips containing it can communicate with
each other using speedy light pulses.
Lasers
grasp cell-size water balloons
Scientists have been using light to move tiny sacks
of fluids smaller than human cells for years. Bigger
versions of these artificial cells that are more
like their biological cousins have been more resistant
to laser manipulation. A new approach shows that
what's inside makes a big difference.
Fuel
cell aimed at handhelds
Fuel cells are getting a lot of attention these
days for their role as favored successor to the
internal combustion engine. Some researchers look
at the fuel cell and see something smaller.
