In ancient Rome, tipplers lined jars of wine with the precious metal to keep it from going bad. Millenia later we are buying refrigerators and socks, with microscopic silver particles to keep them fresh. The particles are called “nanosilver,” and they’re seeping into more and more consumer products.
Now the Environmental Protection Agency (EPA) says it plans to announce formally, in the federal registry, that it will take a look at its regulatory procedures for nanosilver. The announcement follows calls by health and environmental watchdog groups for a crackdown.

A patient without medical insurance downloads a medicine’s formula to his computer. A personal “nanofactory” sits on his desk. It builds the medicine he needs, molecule by molecule, as if printing a document.
Next door, an aspiring tyrant has a nanofactory, too. He’s building guns, lots of guns. Enough to arm a militia.
Mark A. Reed and his Yale colleagues have fashioned nano-wires one millionth of the diameter of a human hair, which hold the promise of hand-held medical scanners that can do blood work and find cancer cells in minutes.
