In the cover story, "The Promise of Plasmonics", a new technology squeezes electromagnetic waves into miniscule structures. It may yield super-fast computer chips, ultra-sensitive molecular detectors and perhaps even invisibility cloaks. Next, "Gassing up with Hydrogen". Researchers are exploring ways for fuel-cell vehicles to hold the hydrogen they need for long-distance travel.
