the quirky world of quantum physics, electrons
are waves as well as particles. Making electron
waves interfere with each other could be a
way to make superfast computers. The key is
replacing ordinary computer circuits with
networks of ultrasmall wire rings.
orchestrates Web presentations
Making multimedia presentations that draw on information
scattered around the Internet means figuring out
how to fetch the right pieces in the right order.
A toolset brings a touch of movie editing to the
glass makes minuscule sensor
Mix the right chemicals with liquid glass, print
small buttons of the liquid onto a surface and you
have a compact sensor that can detect many different
map improves models
Building a realistic model of the Internet is a
tremendous challenge. A pair of researchers is mapping
the real thing to give the model makers some guidance.
The natural effects that cause trash to collect
along river banks and dye to rise in celery stalks
are at the heart of a labs-on-a-chip device that
uses a tiny, circular channel and an ordinary magnet
to concentrate particles like DNA.
