WATER MOLECULES, UNITE!
Compared with other liquids, water is very sensitive to an electric
field. The field strongly "polarizes" water, lining up the charges in
the molecules. In the 15 June Physical Review Letters researchers
use a new calculation scheme to explain this large electric response.
The results shed light on how water polarizes at short distances--the
range relevant for the charged pieces of a protein molecule packed
tightly among water molecules in biological cells.
