Scientists working at the U.S. Department of Energy's Brookhaven
National Laboratory have caused tiny strands of water, each less than
one nanometer (a billionth of a meter) in width, to form inside a
common mineral. These nanoscale "water wires" give the scientists a
new opportunity to study the properties of very small quantities of
water, such as that found inside cells, which behave differently than
water at the macro-scale....

I guess we all here will be happy when water nanotransistor appears!
